Discussion

An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163

Check Content

Verify that OL 9 file system automount function has been disabled and masked with the following command:

$ systemctl is-enabled  autofs
masked

If the returned value is not "masked" and is not documented as operational requirement with the information system security officer (ISSO), this is a finding.

Fix Text

Configure OL 9 to disable and mask the ability to automount devices.

The autofs service can be disabled and masked with the following command:

$ sudo systemctl mask --now autofs.service
