Question 1
Solution: Honeypot is nothing but a mechanism used to enhance the security of computer systems from various illegitimate attackers. Here, in case of a server in use, a server is used as a honeypot, that portrays the same functionalities of the actual main server. The attacker believes this server to be the actual server and tries attacking the server. Any such unusual behaviour is recognised and the attacker is blocked from accessing the server. Thus, the security of the network and the systems involved in it, are significantly enhanced with the aid of honeypots.

Here, the cuckoo is taken as a reference to explain that it lays its egg in another nest, and similarly a malicious user tries to inject or execute his/her program illegitimately causing havoc to the system.

Question 17
Solution: Dictionary attack is nothing but a type of attack wherein an attacker tries several different attempts to break down the secret key or determine the decryption key so that he can be successful in attempting to overwrite the system or the mechanism as a whole. Brute-force attack is nothing but, the attacker gives several attempts to guess the password right before getting access to the system. The similarity between the two attacks is that both the attacks involve several attempts in trying different combination of possibilities. The difference between the two is that in dictionary attack, the attacker only probes the possible passwords from a dictionary and not the complete key space. Whereas in the Brute-force attack, the attacker probes the complete key space.
