Discussion

Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict individuals' and groups' privileges could go undetected. In PostgreSQL environment, modifying permissions is typically done via the GRANT and REVOKE commands. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

Check Content

At the command prompt, execute the following command:

# grep '^\s*log_statement\b' /storage/db/vcops/vpostgres/data/postgresql.conf

If "log_statement" is not set to "all", this is a finding.

Fix Text

At the command prompt, execute the following commands:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "ALTER SYSTEM SET log_statement TO 'all';"
# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "SELECT pg_reload_conf();"
