1.151 RHEL-10-400320

Information

RHEL 10 must define default permissions for the c shell.

GROUP ID: V-281081RULE ID: SV-281081r1184682

The "umask" controls the default access mode assigned to newly created files. A "umask" of "077" limits new files to mode "600" or less permissive. Although "umask" can be represented as a four-digit number, the first digit representing special access modes is typically ignored or required to be "0".

This requirement applies to the globally configured system defaults and the local interactive user defaults for each account on the system.

Solution

Configure RHEL 10 to define default permissions for all authenticated users using the c shell.

Add or edit the lines for the "umask" parameter in the "/etc/csh.cshrc" file to "077":

umask 077
