1.278 RHEL-10-600540

Information

RHEL 10 must require reauthentication when using the "sudo" command.

GROUP ID: V-281209RULE ID: SV-281209r1166579

Without reauthentication, users may access resources or perform tasks for which they do not have authorization.

When operating systems provide the capability to escalate a functional capability, it is critical that the organization requires the user to reauthenticate when using the "sudo" command.

If the value is set to an integer less than "0", the user's time stamp will not expire, and the user will not have to reauthenticate for privileged actions until the user's session is terminated.

Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000373-GPOS-00157, SRG-OS-000373-GPOS-00158

Solution

Add the following line to "/etc/sudoers" or a file in "/etc/sudoers.d":

Defaults timestamp_timeout=0
