Session hijacking has several approaches. What countermeasures exist for this onslaught

Give some examples of the many means through which a session may be taken over by an attacker. The question is how one would protect oneself against such an attack.

To what end does a firewall primarily serve?My current project is a packet-filtering programme. Please direct me to the guidelines.

How are different attacks on message authentication prevented and how are they prevented?

What are some of the other names for the many kinds of firewalls, apart from those that are based on network routers?

Suppose a user employs one-time passwords as above (or, for that matter, reusable passwords), but that the password is transmitted sufficiently slowly. (a) Show that an eavesdropper can gain access to the remote server with a relatively modest number of guesses. (Hint: The eavesdropper starts guessing after the original user has typed all but one character of the password.) (b) To what other attacks might a user of one-time passwords be subject?

Against what dangers is a firewall erected?When filtering packets, there is a certain protocol to follow.

Authorization lists should be encrypted and secured since they are so vulnerable to manipulation. Imagine if someone messed with these files without meaning to.

How may a remote attacker—also referred to as a client attack—gain access to the system when passwords are needed to authenticate users?
