Check: GEN000000-LNX00520

SUSE Linux Enterprise Server v11 for System z STIG: GEN000000-LNX00520 (in versions v1 r12 through v1 r9)

The /etc/sysctl.conf file must have mode 0600 or less permissive. (Cat II impact)

The sysctl.conf file specifies the values for kernel parameters to be set on boot. These settings can affect the system's security.

Check /etc/sysctl.conf permissions: # ls -lL /etc/sysctl.conf If /etc/sysctl.conf has a mode more permissive than 0600, this is a finding.

Use the chmod command to change the mode of the /etc/sysctl.conf file. # chmod 0600 /etc/sysctl.conf
