Finding ID Version Rule ID IA Controls Severity
V-48125 SOL-11.1-040420 SV-60997r1_rule Medium
Description
On many systems, only the system administrator needs the ability to schedule jobs. Even though a given user is not listed in the "cron.allow" file, cron jobs can still be run as that user. The "cron.allow" file only controls administrative access to the "crontab" command for scheduling and modifying cron jobs. Much more effective access controls for the cron system can be obtained by using Role-Based Access Controls (RBAC).
