Information

OpenSSH has the ability to create network tunnels (layer-2 and layer-3) over an SSH connection. This function can provide similar convenience to a Virtual Private Network (VPN) with the similar risk of providing a path to circumvent firewalls and network ACLs.

 NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

To set the PermitTunnel setting, add or correct the following line in '/etc/ssh/sshd_config':

PermitTunnel no
