We recently had an external audit and it was recogmended that we disable SSH-1 on our Cicso Pix 515e. It is currently enabled by default. The current firewall version is 6.3(4) and we currently VPN into this device using Cisco VPN client 5.0.03. We use Transport IPSec over UDP to connect to the Pix via the VPN client. Everything is working well in our network setup and is stable.
My question is if I disable SSH-1 would it effect anything negitivily. How do I know if there is any SSH-1 traffic on the Pix device. I'd like to just disable SSH-1, and not have to upgrade the firewall version. What would be the commands to disable SSH-1?
