1 Preliminary Solution Design Change Log
Any moderate or significant changes to the solution design must be resubmitted to TSG for
review and approval prior to making any actual implementation change(s). In most cases, the review
and approval of any changes would be performed internally within TSG.
Notes:
1. Use of a word processing automated change tracking feature is required when
resubmitting this document in order to simplify the review and approval process. Once a version
of the document has been approved, then that version of the document should be saved for
archival purposes. Prior to submitting a new version of the document, all prior tracked changes
should be accepted. This process for resubmission can then be repeated as many times as
necessary until the final approval has been issued.
2. Failure to resubmit changes for review and approval could result in a recommendation by
TSG that the project approval status be reconsidered. If there are any questions as to
whether or not a change is substantive enough to warrant review and approval, please send
an email on eau.mita@gov.mt for clarification.
3. Maintain a summary of changes in the table below.

Appendix A – Service Contract/Adapter Definition
Section 1 – Functional

Consumption Information
<How is the service going to be consumed?>
(Example: The service provides an SMTP relay from the consumer to gov.mt domains and
other domains registered through ICANN domain registration services, including subdomains
and have the appropriate Mail Exchanger DNS Mechanisms in place.
The transmission of data through the consumption of this service is not secured through the
use of TLS/SSL certificates; therefore it is the responsibility of the consumer to encrypt data.
User authentication for each connection is not required.
Sender domain must be valid and defined by MITA.
Access control is configured through Firewalls at the Segregated Environment Edge.
Each message is scanned against a list of viruses and malicious content)

Interfaces provided
<Provide technical information on how the service can be accessed>

Standards
<Provide the standards which are relevant to the provisioning of the service within the table
below>

Standard
Information

Location of Documentation
<Provide the technical design, including interfacing documentation and architecture blueprint
of this adapter>

(Example: The adapter is monitored through MITA central monitoring services via SNMP. The
uptime availability is available through the MITA hosting services. Each consumer should not
send more than 10 mails per second when messages do not exceed 10 Kilobytes each.
Consumers abusing the system will be disconnected without notice)

Quality of Service
<Specify the quality checks that will be carried out during the design, development and
deployment of this adapter?>
(Example: This adapter was designed according to IETF specifications and best practices. It
is based on IP protocols to ensure scalability and re-usability. The implementation is
controlled by the MITA Change Management process)

Auditing Information
<Specify the auditing mechanisms provided by the adapter, including the data elements that
are recorded for auditing purposes. Include the Data Protection measures that are in place
according to GMICT policy and legislation>

Defined processes
<Specify the processes which are available in order to apply for usage, disconnection or
modifications of this adapter, as well as processes related to the consumer accessibility to the
adapter>
(Example: Requests for consumption of this adapter are controlled by MITA. A change
request is required to open port 25 from the Segregated Hosting Environment to the service
as defined under interfaces.
Requests for access to the adapter are identified through the solution architecture to be
presented according to the Solution Architecture Templates available at http://mita.gov.mt.
Project Manager is responsible to trigger change management process)
