Check: GEN000000-LNX00530

SUSE Linux Enterprise Server v11 for System z STIG: GEN000000-LNX00530 (in versions v1 r12 through v1 r9)

Title

The /etc/sysctl.conf file must not have an extended ACL. (Cat II impact)

Discussion

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

Check Content

Check the permissions of the file. # ls -lLd /etc/sysctl.conf If the permissions of the file or directory contains a '+', an extended ACL is present. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all /etc/sysctl.conf
