The EDB Postgres Advanced Server must generate audit records showing starting and ending time for user access to the database(s) and concurrent logons/connections by the same user from different workstations.
An XCCDF Rule
Description
<VulnDiscussion>For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to the DBMS lasts. This can be achieved by recording disconnections, in addition to logons/connections, in the audit logs. Disconnection may be initiated by the user or forced by the system (as in a timeout) or result from a system or network failure. To the greatest extent possible, all disconnections must be logged. Concurrent connections by the same user from multiple workstations may be valid use of the system; or such connections may be due to improper circumvention of the requirement to use the CAC for authentication; or they may indicate unauthorized account sharing; or they may be because an account has been compromised. (If the fact of multiple, concurrent logons by a given user can be reliably reconstructed from the log entries for other events [logons/connections; voluntary and involuntary disconnections], then it is not mandatory to create additional log entries specifically for this.)
