Resetting GCC-compiler file permissions

Description

This appendix describes the post-deployment configuration of specific file permissions for additional NSP system security.

Read and execute privileges for the “other” user type may be enabled on specific RPM files during RHEL OS installation, upgrade, or update.

As a security-hardening measure after such a RHEL OS operation, you can revoke the privileges, as described in To remove world permissions from compiler executables.

In the event that you need to roll back the security hardening, see To restore compiler world permissions.
