Discussion

An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message.

Check Content

Verify TOSS 5 file system automount function has been disabled using the following command:

$ sudo systemctl is-enabled  autofs

masked

If the returned value is not "masked", "disabled", "Failed to get unit file state for autofs.service for autofs", or "enabled", and is not documented as operational requirement with the information system security officer (ISSO), this is a finding.

Fix Text

Configure TOSS 5 to disable the ability to automount devices.

Disable the "autofs" service using the following command:

$ sudo systemctl mask --now autofs.service
