A security analyst is troubleshooting a scenario in which an operator should only be allowed to reboot remote hosts but not perform other activities. The analyst inspects the following portions of different configuration files:
Configuration file 1:
Operator ALL=/sbin/reboot
Configuration file 2:
Command=”/sbin/shutdown now”, no-x11-forwarding, no-pty, ssh-dss
Configuration file 3:
Operator:x:1000:1000::/home/operator:/bin/bash
Which of the following explains why an intended operator cannot perform the intended action?
- The sudoers file is locked down to an incorrect command
- SSH command shell restrictions are misconfigured
- The passwd file is misconfigured
- The SSH command is not allowing a pty session
