im trying to do some lab for my ccna security. one of them is loading ios ips signature. It seem like you need have special permission to download from cisco. anyone knows is there a way for you to get one just for testing?
If your device is IPs capable it should ship with either 128MB.sdf, 256MB.sdf or attack-drop.sdf in the flash. If you've deleted it you can get any of the three form Cisco.com for nothing. Those files give you some basic signatures that you can load and work with without being under a support contract.
