CHAPTER

Overview
The Cisco Registered Envelope Service (CRES) is a hosted service that provides
support for Cisco IronPort Encryption technology. CRES works in conjunction
with Cisco IronPort Email Security appliances and Cisco IronPort Encryption
appliances, which provide on-premises content scanning, policy enforcement, and
encryption. CRES stores per-message encryption keys for encrypted messages.
Recipients of encrypted messages authenticate themselves with the service to
receive decryption keys.
Note
The latest version of this guide and other CRES documentation is available on this
product page.
Role of Cisco Registered Envelope Service in Encryption
The service manages the following elements of encryption:
•
Recipient enrollment. Recipients of a registered envelope (an encrypted
message) must enroll with the service the first time they open an envelope,
unless the message is sent with low security. Enrollment is free of charge.
•
Authentication. Enrolled users use Single Sign-On (SSO) or provide a
password to open registered envelopes and read encrypted messages.
•
Encryption keys. An encryption key is created for each encrypted message.
When enrolled recipient enter their password in the registered envelope, the
service sends the decryption key that opens the envelope.
Cisco Registered Envelope Service Account Administrator Guide
1-1
Chapter 1
Overview
•
Message expiration and locking. Enrolled users can set the expiration date
and control message locking for the encrypted messages that they send.
Corporate account administrators can control expiration dates and message
locking for all encrypted messages sent using the corporate account.
•
Secure Forward and Secure Reply messages. Depending on the corporate
account configuration, recipients may be able to forward and reply to
encrypted messages using encryption. CRES handles the encryption for
Secure Forward and Secure Reply messages.
The figure shows how CRES works in conjunction with a Cisco IronPort Email
Security appliance. The service supplies the decryption key to the registered
recipient of a encrypted message.
The diagram depicts the following process:
Step 1
A Cisco IronPort Email Security appliance uses encryption to encrypt a message
and deliver it.
Step 2
The recipient enters his or her CRES password in the registered envelope.
Note
If the message is configured for low security, then the recipient need not
enter a password to open the secure envelope.

Step 3
CRES supplies the decryption key that opens the envelope.
Step 4
The recipient’s web browser displays the decrypted message.
Corporate Account Administration
CRES provides administrative functionality for organizations’ corporate
accounts. The initial CRES administration role is assigned to the Registered
Technical Contact. An administrator for a corporate account can perform the
following tasks, among others:
•
Customize the logo displayed on registered envelopes
•
Manage messages sent through the service
•
Generate account usage reports
•
Manage users (such as lock accounts and reset passwords)
•
Configure TLS settings for encrypted secure reply without requiring an
envelope

Administration FAQs
This section provides answers to frequently asked questions (FAQs) about the role
of a Cisco Registered Envelope Service (CRES) corporate account administrator.
What is a Cisco Registered Envelope Service corporate account?
Each organization that uses encryption technology and CRES has a corporate
account with the service. This account can be used in conjunction with one or
more Cisco IronPort Email Security appliances that send encrypted messages.
Typically, an organization has a single corporate account, and the account
administrator(s) manages only that account.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
2-1
Chapter 2
Administration
What are the typical tasks of an account administrator?
Typical administrative tasks include:
Note
•
Configuring the corporate account (for example, uploading an organization’s
logo to display it on Registered Envelopes sent using the account).
•
Monitoring account usage (for example, viewing statistics about user
registration and user account activation).
•
Managing messages sent using the account (for example, disabling access to
a particular message).
Account administrators cannot access the content of user messages that they
manage in the Administration Console.
For more information about administrative tasks, see the “Common Tasks”
section on page 2-8.
Which email administration topics are covered in this guide?
Administration of a Cisco IronPort secure email solution involves two distinct
areas of responsibility:
•
Managing Cisco IronPort appliances, such as Cisco Email Security
appliances and Cisco IronPort Encryption appliances
•
Managing a CRES corporate account
This guide contains information about managing a CRES corporate account. For
information about managing Cisco IronPort Email Security appliances, see the
product documentation available on the Cisco Customer Support Portal.
What is recipient enrollment?
Recipient enrollment, also called user registration, is the process of creating a
CRES user account for a first-time recipient of a Registered Envelope. Most
message recipients must complete the enrollment process before they can open
the encrypted messages that they receive. However, if the message uses low
security, the user can open the message without registering.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
2-2
Chapter 2
Administration
During the enrollment process, the recipient provides user profile information,
chooses a password, and selects security questions and answers.
Cisco Registered Envelope Service Accounts
When a user enrolls with CRES, the user is not associated with a particular
sender’s corporate account.
Senders have accounts, and recipients have accounts. The sender CRES account
allows the sender of an encrypted message to manage their secure messages by
expiring or recalling them.
Users
User account administration is handled by system administrators at CRES.
Typically, corporate account administrators do not manage individual user
accounts.
It is possible for a corporate administrator to manage internal CRES users for the
purpose of resetting passwords or locking existing accounts. If a CRES
administrator wishes to manage their user accounts, a customer support ticket
must be filed to add the managed domains to the account.
What are user groups and roles?
Groups are lists of enrolled users. Roles are sets of privileges that you can
associate with groups. For example, to create an account administrator, someone
with administrative privileges for the account must add the user to the account
administrator group. Roles are not associated with individuals.
Note
Every user in a particular account administrator group can administer that
account.
Cisco Registered Envelope Service 4.6 Account Administrator Guide

Chapter 2
Administration
Getting Started
This section explains how to get started using the Administration Console for a
CRES corporate account.
Understanding the Corporate Account Setup Process
When an organization configures a Cisco IronPort Email Security appliance to
use encryption with CRES as the hosted key service, a corporate account is
created for the organization. The organization’s Cisco IronPort Email Security
appliance is associated with the corporate account.
Note
As a corporate account administrator, you are not involved in the initial account
setup process.
By default, the Account Administrator group for the new account includes the
organization’s initial corporate account administrator. The corporate account
administrator can create additional administrators by adding users to the Account
Administrator group. For more information, see the “Adding a Corporate Account
Administrator” section on page 2-10. The Account Administrator group may also
include IronPort Sales Engineers who are familiar with the organization’s Cisco
IronPort Email Security appliances and system configuration.
Logging In
To manage your corporate account, log in using this URL:
https://res.cisco.com/admin
If you are the administrator for multiple accounts, you are asked to select an
account when you log in. You can then select whether you want:
•
The selected account to be remembered on your computer.
•
The remembered account to be automatically selected the next time you log
in.
Cisco Registered Envelope Service 4.6 Account Administrator Guide

Using TLS Delivery
Transport Layer Security (TLS) delivery allows CRES-originated messages such
as secure replies to be delivered encrypted back to the sending domain without
having to use an envelope.
You can enable TLS delivery to provide a secure method of delivering email
without requiring end users to log in to CRES or install the encryption plug-in to
receive or view email.
TLS is enabled on a per-account basis. For each account, you specify one or more
TLS domains and error handling behavior.
Adding and Testing TLS Domains
To enable TLS for an account, you must add at least one domain. Adding a domain
initiates a process where the domain is scanned for TLS support. A domain must
pass TLS domain testing before it can be added.
The TLS domain test uses the CRES servers to verify information and
connectivity. The check ensures that:
•
that there are MX records associated with the domain entry, and
•
that the MX records can be resolved to an IP address and each MX record has
working mail servers associated with it, and
•
that the CRES servers can establish an SMTP connection via port 25 with the
above-mentioned mail servers, and
Cisco Registered Envelope Service 4.6 Account Administrator Guide
2-20
Chapter 2
Administration
•
that each above-mentioned mail server supports the STARTTLS extension,
and
•
finally, that the CRES servers can initiate a successful TLS connection to
each mail server serving the MX record.
To use TLS for secure replies, you must use a certificate signed by, or chained to,
one of the certificates listed in the Supported Certificate Authorities for CRES
section of the Cisco Email Encryption Compatibility Matrix. You must also use a
certificate that has not expired. A certificate has expired if the date and time when
a TLS connection is made is not within the certificate’s validity window.
A TLS test for a domain generates one of three possible results: pass, inconclusive
(partial pass), and failure.
•
Pass: A domain is considered to pass a TLS test when the test on all servers
in the MX records passes. Domains that pass TLS tests are added as TLS
domains and receive a status of “processing” while they await approval by
Customer Support.
•
Inconclusive: If the test has passed on at least one associated mail server but

default, not added as TLS domains. You can add an inconclusive domain by

TLS Error Handling
If TLS delivery stops working (due to an expired certificate, for example), you
need to configure TLS error handling. You can choose “Bounce Messages” or
“Fallback to Registered Envelope Delivery.”
Note
If the TLS failure delivery preference is set to “Fallback to Registered Envelope
Delivery,” remember to change the TLS delivery option to TLS Preferred on your
in-house mail server.
•
Fallback to Registered Envelope Delivery: If the TLS delivery fails (due to
an expired certificate, for example), the system reverts to sending registered
envelopes.
•
Bounce Messages: For accounts configured to bounce messages during TLS
delivery failure, the bounce will happen after 24 hours, during which a retry
will be attempted every hour. For accounts configured to fall back to
registered envelope delivery, fall back will happen after 1 hour, during which
a retry will be attempted every 20 minutes.

SAML is an XML application for Single Sign-On (SSO). For further information
on how CRES implements SAML authentication, see Authenticating with SAML,
page 2-26.
You may want to use SAML-based authentication if you are already using the
Cisco IronPort Web Security Appliance or PingFederate as a SAML identity
provider for SSO. For more information, see Configuring the PingFederate

Authenticating with SAML
SAML is an XML-based standard primarily used for Single Sign-On (SSO), a
simpler way for end users to authenticate with multiple web services, such as
CRES. Currently only SAML 2.0 is supported.
Single Sign-On means users log in once to authenticate (with an identity provider)
and thereafter use a range of services from service providers without having to log
in again. The protocol also supports Single Log-Out.
This simplifies the user experience, and improves security because the user no
longer has to remember login details for multiple services. CRES support for
SAML works for new and existing CRES envelopes. SAML authentication must
be enabled individually for each corporate account. After this is done, all users in
that account must authenticate with SAML. Any users not owned by the account
will continue to use CRES authentication.
Cisco Registered Envelope Service 4.6 Account Administrator Guide

Chapter 2
Administration
SAML Overview
SAML enables exchanging authentication and authorization data between
different secure networks, sometimes referred to as security domains. Typically,
SAML is used when there are users in one domain accessing a network (a different
domain) using a web browser.
To achieve Single Sign-On, a SAML dialogue must be engaged by an entity in
each domain, which SAML defines using the following terms:
•
Identity provider (IdP). An identity provider is an entity that produces
SAML assertions. The identity provider is expected to authenticate its end
users before producing a SAML assertion. CRES should work with most
SAML 2.0 identity providers. However, it is certified to work only with the
Cisco IronPort Web Security Appliance, Active Directory Federation
Services (AD FS), and PingFederate.
•
Service provider (SP). A service provider is an entity that consumes SAML
assertions. The service provider relies on the identity provider to identify the
end user and communicate that identification to the service provider in the
SAML assertion. The service provider makes an access control decision
based on the assertion. With SAML authentication enabled, CRES acts as a
service provider.
SAML assertions are containers of information passed between identity providers
and service providers inside SAML requests and responses. Assertions contain
statements (such as authentication and authorization statements) that service
providers use to make access control decisions. Assertions start with the
<saml:Assertion> tag.
SAML dialogues are called flows, and flows can be initiated by either provider:
•
Service provider initiated flow. The service provider is contacted by an end
user requesting access, so it starts a SAML dialogue by contacting the
identity provider to provide identification for the user. For service provider
initiated flows, the end user accesses the service provider using a URL that
contains the service provider’s domain, such as
http://www.serviceprovider.com/.
•
Identity provider initiated flow. The identity provider starts a SAML
dialogue by contacting the service provider, requesting access on behalf of an
end user. For identity provider initiated flows, the end user accesses the
service provider using a URL that contains a local domain, such as
http://saas.example.com/.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
2-27
Chapter 2
Administration
CRES supports only service provider initiated flows.
Note
This section does not provide a comprehensive discussion of SAML, nor how
identity and security providers communicate with each other. For more detailed
information, see http://saml.xml.org/wiki/saml-wiki-knowledgebase.
For further information about using the Web Security appliance as an identity
provider, see the “Controlling Access to SaaS Applications” chapter in the Cisco
IronPort AsyncOS for Web User Guide (release 7.0 or later).
Requirements
To use SAML authentication with CRES as the service provider, the following
requirements must be met:
•
CRES currently supports using only the Cisco IronPort Web Security
Appliance, Active Directory Federation Services (AD FS), or PingFederate
as an identity provider.
•
The indentity provider’s SAML login mechanism must be able to work
without JavaScript.
•
The identity provider must support SAML 2.0.
•
In the SAML assertion, the SAML NameID or attribute must contain the
email address.
Caveats
There are some caveats when using SAML authentication:
•
SAML must be enabled individually for each corporate account.
•
The SAML login page is provided by the SAML identity provider, not by
CRES. This means no CRES logging is available for the SAML logins and
login problems should be reported to your SAML identity provider.
•
User password maintenance, such as recovering a forgotten password or
changing a password, must be performed via the identity provider, not CRES,
for users with SAML-authenticated accounts.
•
SAML authentication is not enabled for administration accounts (admin
config) to prevent those accounts being inadvertently locked out.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
2-28
Chapter 2
Administration
•
Unlike CRES-authenticated accounts, you cannot consolidate SAML
authenticated accounts.
•
When the Cisco IronPort Web Security Appliance is used as the identity
provider, JavaScript must be enabled for the login page to function correctly.
•
When the Cisco IronPort Web Security Appliance is used as the identity
provider, passwords are not cached and the user must authenticate every
session.
•
If there is a problem with the identity provider, SAML users may be unable
to authenticate even when their credentials are valid.
•
If the identity provider becomes permanently unavailable, you must change
the authentication method to CRES to enable users to authenticate.
•
The administrator is dependent on the identity provider to provide an alert if
there is a problem with the SAML service.
•
Even if end users have valid credentials, they may be unable to access the
service if there is a problem with the identity provider.
User Experience
The user experience with SAML authentication is much the same whether
JavaScript is enabled, whether there are one or more recipients, or whether those
are BCC recipients. Users open an envelope (or Mobile Device Support (MDS)
link), select their user identity or provide their email address as required, and
authenticate through the identity provider. Alternatively, users can navigate to
https://res.cisco.com in a web browser, enter an email address, and authenticate
through the identity provider.
Configuring SAML Account Authentication
You can configure SAML authentication to use one of the following identity
providers:
•
Active Directory Federation Services (AD FS)
•
Cisco Ironport Web Security Appliance
•
PingFederate
The configuration procedures for using these identity providers are described in
the following sections:

Configuring SAML Account Authentication When Using AD FS as the Identify Provider
When you enable SAML authentication, it is very important to configure the
CRES account to match the settings of the AD FS account.
You will need the following information (AD FS equivalents):
•
Service provider entity ID (SaaS application name / connection ID)
•
Customer service URL (Single sign-on URL / base URL)
•
Identity provider verification certificate
•
(Optional) Alternate email attribute name (SAML attribute / email address)

CRES compares the user’s name from Active Directory with the user’s CRES
account.
To use “E-Mail Addresses,” value, you must enter the email address in the
“E-mail” field under the General tab of the User’s Properties configuration.
Because CRES takes the email address from the user’s account in Active

Configuring SAML Account Authentication When Using a Cisco Ironport Web Security Appliance or
PingFederate as the Identify Provider
When you enable SAML authentication, it is very important to configure the
CRES account to match the settings of the identity provider account.
You will need the following information (Cisco Ironport Web Security Appliance
or PingFederate equivalents):
•
Service provider entity ID (SaaS application name / connection ID)
•
Customer service URL (Single sign-on URL / base URL)
•
Identity provider verification certificate
•
(Optional) Alternate email attribute name (SAML attribute / email address)
If you are using the Cisco IronPort Web Security Appliance as the identity
provider, this information can be found on the SaaS Application Authentication
Policies page. The certificate can be downloaded from the Edit Identity Provider
Settings for SaaS Single Sign On page.
If you are using PingFederate as the identity provider, this information can be
found in the Summary area.
Note
When configuring PingFederate as the IDP, you must specify the CRES Assertion
Consumer Service URL as an endpoint. In addition, for the users to log out, the
SSO Logout URL must be configured. For instructions on configuring this
setting, see “Configuring the PingFederate Logout URL” on page 37.
To configure SAML authentication for an account:

The Single Sign-On binding, typically HTTP-Redirect or HTTP-POST, is
displayed together with the SSO Assertion Consumer URL.
Step 8
(Optional) Click Download to download a copy of the SSO service provider
verification certificate. This is the public self-signed certificate that is required by
your identity provider (IdP) to verify the signature of the SAML logout request
from CRES.
Step 9
Click Browse, and select and upload the SSO identity provider verification
certificate, provided by the SAML identity provider (Cisco IronPort Web Security
Appliance or PingFederate). The current certificate is displayed.

When you have saved the details, you must then activate the SAML login.
This prevents you from accidentally locking out users in case of a
configuration error.
Configuring the PingFederate Logout URL
In order to log out from an envelope that was configured with PingFederate as the
IDP, the logout URL must be configured in PingFederate. This is critical because
the end user must click the logout button to completely log out of CRES.
To configure the logout URL in PingFederate:
Step 1
From the CRES Account Management screen for the account, download and save
the public certificate.
Step 2
On the PingFederate server for the account, click Signature Verification
Certificate.

administrator for more information.
If DNS is not configured to include CRES, when secure compose and secure
replies are generated and delivered through the hosted key servers, the outgoing
IP address will not match the listed IP addresses at the recipients end, resulting in
a SPF verification failure.

Information About Migrating the Data Needed to
Create Keys from the IEA to CRES
If you have an existing installation of Cisco Ironport Encryption Appliance (IEA)
and you want to use Cisco Registered Envelope Service (CRES) for key creation
and management, instead of using IEA as a local key server, you must perform the
migration procedure.
The preferred method is to copy all existing user and key data from IEA into
CRES so that the end users can still open their old envelopes and will not need to
re-register. To do this, CRES now provides a data migration client for the IEA and
a data import service for CRES. These utilities use the existing hardware and do
not require any changes to your infrastructure, allowing you to continue to take
advantage of existing capabilities such as load balancing and failover.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
OL-22158-02
4-1
Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
By default, the migration client will perform one pass at migrating the data. You
can configure the client to run multiple passes. The migration client keeps track
of which records have already been sent and will not re-send any data that has
already been received by CRES.
After the IEA records have been migrated, you must complete several steps to
ensure the redirection of traffic from the IEA to CRES. These steps are described
in detail in the next section and include, but are not limited to:
1.
Set up the redirection of HTTP traffic from end users to go to an HTTP proxy
instead of to the IEA.
2.
Set up the HTTP proxy to use an existing or new SSL certificate that the end
users can trust for their HTTP traffic with the proxy, in place of the certificate
used with the IEA. You must use a certificate signed by, or chained to, one of
the certificates listed in the Supported Certificate Authorities for CRES
section of the Cisco Email Encryption Compatibility Matrix.
3.
Configure the proxy to use an SSL certificate for trusted HTTP
communication with CRES.
4.
Update your DNS server and firewall rules to redirect all HTTP traffic
intended for the IEA to go to your HTTP proxy instead.
5.
Update the tokens on all encryption appliances and clients.
6.
Disable the IEA.
7.
Associate your email domains with your CRES account.
Because the switchover process is not instantaneous, some IEA clients may
continue to use the IEA, so there may be database updates that need to be mirrored
to CRES. You can configure the data migration client to periodically check for
any updated data and to migrate any updated data to CRES.
The CRES administrator can configure simple policies that permit the importation
of keys for a given account and that specify time periods when data can be
imported.
The migration process will copy user data and any pending user activity from IEA
to CRES. However, the migration data will not include any user role or permission
data, and the migration process will not change the CRES permissions for account
administrators or any other user belonging to an account. So, the permissions for
users will not be upgraded to those for account administrators on CRES, but if a
user already has account administrator permissions, that access will not be
removed, regardless of their status on the IEA. After the migration, users can be
upgraded to account administrators in the usual manner.

How to Migrate the Data Needed to Create Keys from
the IEA to CRES
Migration Prerequisites
Before you migrate to CRES, you must meet the following perquisites:
•
Ensure that you do not need to use any existing features that will not
supported after you migrate to CRES. For more information and examples of
these features, see the “Features That Are Not Supported on CRES” section
on page 4-4. Discuss your situation with Cisco Technical Support when you
contact them to initiate the migration process.
•
Ensure that the person performing the migration is a database administrator
or has access to a database administrator that can help them.
•
Ensure that you have a machine that can be used as an HTTP proxy and the
software required to run an HTTP proxy.
•
You must upgrade your Cisco IEA software to version 6.5.6.1.
•
If you do not have a CRES account, send an email to
stg-cres-provisioning@cisco.com and provide the following information:
– Name of the account—This is usually a company name. For Hosted
customers, the account name should be “Company Name ‹ HOSTED”
– Customer’s mail address that will be used for the Account Administrator
– Serial number(s) of ESA appliances that will be doing the encryption
•
Initiate the migration process by contacting a Cisco Customer Support
Representative at iea-migrations@cisco.com and providing the following
information:
– Your CRES account number. If you do not have a CRES account, contact
Cisco to create an account, as described in the previous prerequisite.
– The date that you would like to start the migration. You should contact
Cisco at least 30 days before you plan to actually perform the migration.
The Cisco Customer Support Representative will then:
– Configure your account to enable migration.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
OL-22158-02
4-3
Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
– Set the start and end date and times for the migration.
– Send you an email with the details of your account and links to the
migration software.
– Send you an email with the security key in a secure envelope.
•
Download the following installation script as instructed in the email sent to
you by the Cisco Customer Support Representative:
– cres-dbmigrate_install-4.5.1.xxx.sh
•
Verify that the installation script downloaded correctly by running the
following command and comparing the SHA1 digest printed to the console
against the SHA1 digest shown on the download site:
openssl dgst -SHA1 cres-dbmigrate_install-4.5.1.xxx.sh
•
Obtain the following items as described in the first two steps in the procedure
that follows:
– token.jar
– security key (emailed to you in a secure envelope after you schedule your
migration.
•
If you use PostgreSQL to manage your database, you must have PL/pgSQL
installed in order to run the database modification script for Step 4 below.
Features That Are Not Supported on CRES
When you migrate to CRES, you must use a Cisco Email Security Appliance
instead of your Cisco Ironport Encryption Appliance (IEA). Because CRES is a
hosted service, it cannot support some of the features provided by a local key
server, such as an IEA. Therefore, before you migrate to CRES, you must make
sure that you do not need any IEA features that are not supported on CRES.
To help you determine whether you can migrate to CRES, the following list
includes some examples of commonly used IEA features that are not currently
available on CRES:
•
ORACLE database — An IEA using Oracle is not currently eligible for
migration. This will be supported in a future release.
•
Secure mailbox
•
LFS (large file support)

OL-22158-02
Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
•
Statement delivery
•
Some authentication methods — Users registered in the CRES local database
and SAML (for customer owned email domains only) are the only available
authentication methods for CRES. The remaining IEA authentication
methods such as LDAP, Kerberos, and others are not supported. Also,
authentication lookups in multiple sources (known as chained lookups) are
not supported.
For detailed information about IEA features, see the Cisco Ironport Encryption
Appliance 6.5 Configuration Manual.
Migration Procedure
To migrate data from IEA to CRES:
Step 1
Save the token.jar file to your local drive:
a.

b.
Choose the Manage Accounts tab.
c.
Choose the Customer Account Manager’s account.
d.
Choose the Tokens tab.
e.
Click the download icon under the Actions column for the SecureCompose
token in the table of tokens.
Step 2
The security key will be emailed to you by Cisco Technical Support in a secure
envelope after you schedule your migration.
Step 3
Install the migration client on the IEA.
a.
Enter the following commands to use SCP to copy the migration client files
to your IEA.
scp cres-dbmigrate_install-4.5.1.xxx.sh admin@<IEA IP Address>:

Note
d.
Migrating the Data Needed to Create Keys from the IEA to CRES
The x option is a hidden command and does not appear in the list of menu
options.
Use the following command to install the migration client:
sh ./cres-dbmigrate_install-4.5.1.xxx.sh
Step 4
Run the database modification script.
•
For PostgreSQL, enter:
cd dbmigrate/scripts/postgres
psql -p 5432 -h localhost -d database-name -U db-admin-name
-f ~/dbmigrate/scripts/postgresql/migration_table.sql
Note
You must have PL/pgSQL installed to complete this procedure.
•
For MSSQL, copy the script to a Windows machine with the SQL Server
administrator tools installed and execute the script by either:
– Using the SQL Server Management Studio GUI
– Running the following CLI command:
sqlcmd -H hostname -S sqlserver-instance-name -d database-name -U
db-admin-name -P db-admin-password -i migration_table.sql
Step 5
Work with Cisco Technical Support to set the parameters in the
dbmigrate.properties file, which are used to configure the functionality of the
migration client. These parameters are described in the following table.
In addition to the basic configuration parameters shown in the following table,
you can also use several more advanced parameters, which are explained in
Appendix B.
One of the functions that you can configure is the sending of a notification email
to you and Cisco Technical Support when the migration is complete. Configure
the following parameters for this notification: mailserver, mailserverport,
notifyComplete, notificationRecipient, and notifyCompleteForm.
Cisco Registered Envelope Service 4.6 Account Administrator Guide

OL-22158-02
Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
You can also configure the sending of a notification email to end users when the
migration of their data is complete. If you configure notifications for end users,
Cisco recommends that you explain the migration process to your end users to
avoid any confusion when they receive the notification email. Therefore, this
functionality is considered an advanced feature. For information about the
optional advanced parameters for end user notifications, see Appendix B.
You can configure the migration client parameters listed in the following table
using either in the dbmigrate.properties file or using CLI. The
dbmigrate.properties file is located in the conf subdirectory of the folder with the
migration client installer:

Migrating the Data Needed to Create Keys from the IEA to CRES
Step 6
Enter the following command to run the dbmigrate_check script:
./dbmigrate_check
The dbmigrate_check script verifies that the migration client is configured
properly (the tables needed for migration are created, and you have proper token
and security key). The script also provides information on the user, key, contact,
uuid count, keys count by year and checks the database for non-PostxAuth keys.
The following information from database will be printed to the console:
Step 7
•
Count of keys in the T_KEYSTORE table
•
Count of users in the T_USER table
•
Count of users in the T_CONTACT table
•
Count of users in the T_UUID table
•
Count of keys split by year in the T_KEYSTORE table
•
Count of keys in the T_EXPORT_KEYSTORE table
•
Count of users in the T_EXPORT_USER table
•
Warning if your database uses the non-PostxAuth keys (the T_KEYSTORE
table)
Enter the following command to run the script included in the downloaded files
to start the migration client.
./dbmigrate_client --password=db_password
When the migration is complete, the migration client sends a completion
notification email to you and Cisco Technical Support, if you configured the
mail server and notification parameters as described in Step 5. Cisco Technical
Support then checks the results of the migration and notifies you whether the
migration was successful.
Note
User account and domain membership will not be handled by the migration
process. Existing user records will not be moved to a different account, and all
new user records are added to the default Users account (id 1). Cisco Technical
Support must log in and manually move users to the correct account after the
migration.
If the IEA user already exists on CRES, the CRES data for that user is preserved
and no error message is generated.
Cisco Registered Envelope Service 4.6 Account Administrator Guide
OL-22158-02
4-9
Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
If the sender of IEA message cannot be found on CRES (for example, when
messages were sent from currently inexistent or removed user), this key will not
migrate, and error message will be shown. To migrate such keys, you need to
create an appropriate user on CRES manually and rerun migration.
After the migration is complete, and the proxy is set up, your users will need to
use their CRES credentials to open envelopes instead of their IEA credentials. It
is the Administrator’s responsibility to inform the end users that this will happen.
Step 8
After the migration is complete, you must set up the redirection of HTTP traffic
from end users to go to an HTTP proxy instead of the IEA. The traffic that needs
to be redirected includes:
•
Key server requests to create a new key for an envelope or retrieve a key for
an existing envelope
•
Connections to Websafe
•
Connections to Secure Compose
•
Connections to the online envelope opener
•
Connections to any other web applications
To redirect this traffic, you should set up an HTTP/HTTPS proxy to act in place
of the IEA. How you implement this proxy depends on your existing network. If
you do not have an existing web server or proxy server on which to run the HTTP
proxy, you will need to set up a new machine to run the HTTP proxy. For an
example configuration, see the “Example Configuration of HTTP Proxy” section
on page 4-14.
Note
After the migration process, the default CRES logo will be displayed
instead of your custom logo for the IEA secured envelopes. To set up your
custom logo, configure the proxy to change the requests for an IEA
custom logo to requests for a CRES custom logo.
An example of the IEA logo request is at
https://customer_domain/websafe/branding/customer-logo.gif
An example of the request for the CRES custom logo is at
https://res.cisco.com/websafe/logo/your_CRES_account_ID/branding/c
ustomer-logo.gif
To add a custom logo to your CRES account, see the “Customizing the
Logo on Registered Envelopes” section on page 2-8.

Chapter 4
Migrating the Data Needed to Create Keys from the IEA to CRES
Step 9
Note
Set up the HTTP proxy to use an existing or new SSL certificate that the end users
can trust for their HTTP traffic with the proxy, in place of the certificate used with
the IEA.
You must use a certificate signed by, or chained to, one of the certificates listed
in the Supported Certificate Authorities for CRES section of the Cisco Email
Encryption Compatibility Matrix.
SSL version 3 will not be supported in future releases. Therefore you should make
sure that you use software that works with Transport Layer Security (TLS).
You can use the same certificate that you used with the IEA, if it is signed by a
supported Certificate Authority, or you can use a new one. If possible, Cisco
recommends that you use your existing certificate.
Step 10
Configure the HTTP proxy to use an SSL certificate for trusted HTTP
communication with CRES.
The best way to do this is to configure the proxy to reference a trusted store of CA
certificates. A less manageable alternative is for you to configure the proxy to
explicitly trust the CRES certificate, but this approach requires you to update the
explicit trust relationship every time the CRES certificate is updated.
Step 11
Once you set up the HTTP proxy, you must update your DNS server and firewall
rules to redirect all HTTP traffic intended for the IEA to go to your HTTP proxy
instead.
Step 12
Update the tokens on all encryption appliances and clients. This is required for the
encryption and decryption of keyserver parameters to work.
To update the token on the Cisco Email Security Appliance, a CRES encryption
profile should be provisioned. To update the tokens on clients such as the Outlook
plug-in, the Cisco BCE Mobile App for Android, and the Cisco BCE Mobile App
for iOS, download a new BCE configuration file created with a CRES profile and
send it to those users as an encrypted email from an administrator of the CRES
account.
Step 13
Stop the IEA encryption server, but do not physically disconnect the IEA.

4-11
Chapter 4
Step 14
Migrating the Data Needed to Create Keys from the IEA to CRES
Run the migration client again to propagate any updates since the first run.
Alternatively, you can leave the migration client running in multiple pass mode.
Once the second run has completed successfully, Cisco Technical Support
disables further migration for the account.
Step 15
Contact Cisco Technical Support to associate your email domains with your
CRES account. As part of this process, Cisco Technical Support will move any
preexisting CRES users within those email domains to your accounts. Only email
domains owned by you can be associated with your CRES account.
Differences In Functionality Once the Migration Is Complete
CRES has a different feature set than IEA and this difference may cause some
confusion with your users. Cisco recommends that you educate your users on
differences in functionality between the two feature sets.
For detailed information about IEA features, see the Cisco Ironport Encryption
Appliance 6.5 Configuration Manual.
Also, as stated in Step 15 above, if an email account is not owned by you, it cannot
be associated with your CRES account. Emails originating from those accounts
will therefore have a different domain name in the email alias. Cisco recommends
that you also educate your users on this difference to help them avoid confusion.

Migration Error Messages
The following error messages are the most common messages that will be
generated during the migration process. If you receive any other error messages,
contact Cisco Customer Support for information about how to resolve the issue.
Error Message
This IEA database uses a non-standard authentication system for
keys, you may continue with this migration, but when these keys
are moved to CRES they will be modified to use CRES
authentication.
Explanation The IEA database is using a key server authentication type other
than PostXAuth.
Recommended Action As a workaround, you can respond Yes to continue with
the migration and use CRES authentication, but we recommend that you
contact Cisco Customer Support before you make that decision.
Error Message
This IEA database uses non-standard key authentication, i.e.,
C_LOOKUPNAME <> 'PostXDatabase' and the Keystore checker failed
to prompt the user for resolution (console not available).
Explanation The IEA database is using a key server authentication type other
than PostXAuth, and the precondition.keychecker.actionOnFail parameter is
set to fail.

Example Configuration of HTTP Proxy
This example shows how to configure one of the most commonly used products
when configuring a HTTP/HTTPS proxy, the Apache HTTP server. This is by no
means the only possible example or the most recommended product. Your
infrastructure will determine which product is best for you to use as an
HTTP/HTTPS proxy.
Use the following procedure to configure this scenario.
Step 1
Enable the proxy and SSLs by entering the following commands in the Apache
httpd.conf file or the equivalent file.
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule ssl_module modules/mod_ssl.so
Step 2
Make sure the CA certificates are located in the appropriate folder (for example,
in /etc/ssl/certs) and enter the following command to configure the Apache server
to look for the CA certificate in that folder.
SSLCACertificatePath /etc/ssl/certs/
Step 3
Install the IEA certificate by copying the certificate file into the directory that
your Apache installation uses for certificates (for example,
/etc/ssl/your-host-certificate.pem).
Step 4
Enable proxying for HTTP port 80 by entering the following commands:
<VirtualHost www.your-hostname.com:80>
ServerName www.your-hostname.com

Additional Parameters for Migrating
the Data Needed to Create Keys from
the IEA to CRES
In addition to the parameters used in the migration client’s dbmigrate.properties
file or the command line that are described in Chapter 2, you can also use the
parameters in the following table.
You should not change the default values of these parameters using either the
dbmigrate.properties file or the command line, without the help of Cisco
Technical Support.
The max-Errors parameters indicate the maximum number of errors that can occur
before the migration client abandons the current run. A value of 0 for the
max-Errors parameters indicates that there is no limit to the number of errors that
can occur.
Some parameters are used for the key checker process to specify the preconditions
that must be met before the migration can be run. The key checker process scans
the database for the presence of any key server authentication types other than
PostXAuth. You can configure the parameters to cause the key checker process to
take specific actions if the specified preconditions are not met.
For information about the errors that can occur during the migration process, see
the “Migration Error Messages” section on page 4-13.
