Question 1. If an attacker is trying to do an attack with telnet how to avoid that attack? Answer: If an attacker is trying to do a DOS attack then we can block that login with the IOS login enhancement concept. Login block for 30 attempts 2 within 15. The give command gives the possibility that if any user failed login for 2 attempts then it will block that user for 30 sec within 15 sec. If someone is trying to take access so this way we can protect the router with the customized timings.
