PHTN-40-000267 - The Photon operating system must be configured to use the pam_deny.so module.

Information

Configuring the operating system to implement organizationwide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DOD that reflects the most restrictive security posture consistent with operational requirements.

Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters impact the security state of the system and include the parameters required to satisfy other security control requirements. Security-related parameters include, for example, registry settings; account, file, and directory permission settings; and settings for functions, ports, protocols, services, and remote connections.

Solution

Navigate to and open:

/etc/sysctl.d/zz-stig-hardening.conf

Add or update the following line:

fs.suid_dumpable = 0

Note: "0" is recommended for normal operation. If core dumps need to be captured for troubleshooting purposes, then "2" is also an acceptable value.

At the command line, run the following command to load the new configuration:

# /sbin/sysctl --load /etc/sysctl.d/zz-stig-hardening.conf

Note: If the file zz-stig-hardening.conf does not exist, it must be created.
