Discussion

Configuring the operating system to implement organization-wide 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.

Check Content

From the ISPF Command Shell enter:
ISHELL
/etc/profile
If the final or only instance of the UMASK command in /etc/profile is specified as "umask 077", this is not a finding.

If the LOGNAME variable is marked read-only (i.e., "readonly LOGNAME") in /etc/profile, this is not a finding.

Fix Text

Configure the etc/profile to specify the UMASK command is executed with a value of 077 and the LOGNAME variable is marked read-only for the /etc/profile file, exceptions are documented with the ISSO.
