tcp trace packets

Hi all,

Is there anyway of blocking tcp trace packets that are being sent from outside interface to inside ? i have an application that is listening on port 80. Now its a requirement that hackers or unwanted users should not be able to send tcp trace packets to this port, it needs to be blocked ?. Is there anyway of doing it ?

Hello John,

The idea is that if your internal http server is availible for everyone, different scanners will identify this port as opened. Only thing that you can do, is to allow access to this server only for trusted sources using access-lists.

Thank you.
