CD12-00-005100 - PostgreSQL must generate audit records when successful logons or connections occur.

Information

For completeness of forensic analysis, it is necessary to track who/what (a user or other principal) logs on to PostgreSQL.

Solution

Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging.

If logging is enabled the following configurations must be made to log connections, date/time, username, and session identifier.

First, as the database administrator (shown here as 'postgres'), edit postgresql.conf:

$ sudo su - postgres
$ vi ${PGDATA?}/postgresql.conf

Edit the following parameters as such:

log_connections = on
log_line_prefix = '< %m %u %d %c: >'

Where:
* %m is the time and date
* %u is the username
* %d is the database
* %c is the session ID for the connection

Now, as the system administrator, reload the server with the new configuration:

$ sudo systemctl reload postgresql-${PGVER?}
