Configure PostgreSQL to produce audit records when unsuccessful attempts to delete privileges occur.
All denials are logged if logging is enabled. To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging.
Note: The following instructions use the PGDATA environment variable. See supplementary content APPENDIX-F for instructions on configuring PGDATA.
First, as the database administrator (shown here as "postgres"), create the roles joe and bob with LOGIN by running the following SQL:
$ sudo su - postgres
$ psql -c "CREATE ROLE joe LOGIN"
$ psql -c "CREATE ROLE bob LOGIN"
Next, set current role to bob and attempt to alter the role joe:
$ psql -c "SET ROLE bob; ALTER ROLE joe NOLOGIN;"
Now, as the database administrator (shown here as "postgres"), verify the denials are logged:
$ sudo su - postgres
$ cat ${PGDATA?}/pg_log/<latest_log>
< 2016-03-17 11:28:10.004 EDT bob 56eacd05.cda postgres: >ERROR: permission denied to alter role
< 2016-03-17 11:28:10.004 EDT bob 56eacd05.cda postgres: >STATEMENT: ALTER ROLE joe;
If audit logs are not generated when unsuccessful attempts to delete privileges/permissions occur, this is a finding.
