Check: GEN001200

Solaris 10 X86 STIG: GEN001200 (in versions v2 r4 through v1 r17)

Title

All system command files must have mode 755 or less permissive. (Cat II impact)

Discussion

Restricting permissions will protect system command files from unauthorized modification. System command files include files present in directories used by the operating system for storing default system executables and files present in directories included in the system's default executable search paths.

Check Content

Check the permissions for files in /etc, /bin, /usr/bin, /usr/lbin, /usr/ucb, /sbin, and /usr/sbin. Procedure: # ls -lL /etc /bin /usr/bin /usr/lbin /usr/ucb /sbin /usr/sbin If any command file is listed and has a mode more permissive than 755, this is a finding. Note: Elevate to Severity Code I if any command file listed is world-writable.

Fix Text

Change the mode for system command files to 755 or less permissive. Procedure: # chmod 755 <filename>
