Security Concerns
You might be concerned about security with the
current support of SSH for the following reasons:
- Only RADIUS user authentication is supported. If you disable
user authentication, all users are accepted if the client and server
successfully complete negotiation.
- Because the load on the system CPU increases with use
of SSH, you might be concerned about denial-of-service attacks. However,
the forwarding engine takes care of this issue, because it limits
the rate at which it sends packets to the system controller. A flood
of packets from a packet generator does not cause problems regardless
of whether SSH is enabled.
