SECURITY
Lock-down
•
Restrict access to only those host paths and files that are included in that
server’s list of permitted resources
NOTE: Lock-down is not fully supported by all SAS tools and solutions.
Metadata-bound libraries
•
Universally enforce metadata-layer permission requirements for physical
tables—regardless of how a user requests access from SAS
SAS/SECURE
•
Automatically delivered with Base SAS at no additional cost*
Advanced Encryption Standard (AES) with SAS/SECURE
•
Encrypt SAS data on disks
* United States export regulations on encryption software restrict access to
SAS/SECURE software and related technical data.

EXTENDED
ATTRIBUTES
CUSTOMIZED ATTRIBUTES FOR DATA SETS
AND VARIABLES
Extended attributes are customized metadata for your SAS
files. They
• Can be defined on a data set or on an individual variable
• Are organized into (name, value) pairs
• Can be numeric or character – no pre-defined limit on the
number of bytes allowed for a character value
• Are managed by PROC DATASETS
• Base engine support with more to follow (MLE, ACCESS)
