How to check hacking attempts ?

[Steve Harvey]

Hi all;

Is there anyway to check who is trying or have tried to hack network ? I am using ASA 5520 firewall. Is there any command to check it ?

Thanks.

Hi,

You can start by using the 'show local-host' command. This would show you if there's multiple attempts for a half-opened TCP sessions. You could narrow it down to known IP such as servers.
