Fix Recommendation

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.

As the system administrator, change the permissions of PGDATA:

$ sudo chown -R postgres:postgres ${PGDATA?}
$ sudo chmod 700 ${PGDATA?}

As the system administrator, change the permissions of pgsql:

$ sudo chown -R root:root /usr/pgsql-${PGVER?}

Check Contents

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.

As the database administrator (shown here as "postgres"), verify the permissions of PGDATA:

$ sudo su - postgres
$ ls -la ${PGDATA?}

If PGDATA is not owned by postgres:postgres or if files can be accessed by others, this is a finding.

As the system administrator, verify the permissions of pgsql shared objects and compiled binaries:

$ ls -la /usr/pgsql-${PGVER?}/bin
$ ls -la /usr/pgsql-${PGVER?}/include
$ ls -la /usr/pgsql-${PGVER?}/lib
$ ls -la /usr/pgsql-${PGVER?}/share

If any of these are not owned by root:root, this is a finding.
