Packet filter firewall
It uses a set of rules to determine whether outgoing or incoming data packets are allowed to pass through

Circuit level firewall
It is quite similar to the packet filter firewall. It also works on the basis of a set of rules for filtering packets
but operates at the transport layer of the OSI Model so has greater functionality.
Application gateway firewall
It operates at application layer of the OSI Model. It uses strong user authentication to verify identity of a
host attempting to connect to the network using application layer protocols such us FTP. In contrast to
packet filter firewall, it filters the requests rather than packets entering/leaving the network. It can block
any outgoing HTTP or FTP requests.

How „Man in The middle Attacks‟ operates?
Man in the middle attacks
In it the attacker is able to monitor, capture and control data between sending and receiving
machines. He may apply IP address spoofing technique to divert the packets to its machine, then
modify the packets and resend the misleading information to the actual client. Another form of man-
in-the-middle attack is where the hacker is able to substitute the IP address of a genuine web site
with the IP address of his own web site due to some security hole in the software that runs on a
domain name server. A client would think that he is communicating or receiving the information
form a genuine web site, though it would not be the case actually.

Question No: 20 ( Marks: 3 )
What do you think, is there any difference between Static and Dynamic IP Address assignment? Discuss.
A static IP address is an address that does not change over time unless changed manually. It is used when you need the IP address or network location to remain the same consistently. A good example of this is for a web server. If you go to www.google.com you are really going to the IP address of 66.102.7.99. If this were to change suddenly you would not be able to get to Google unless you knew the new IP address or until Google updated their DNS records.
A Dynamic IP address is an address that keeps on changing. It is mostly used when having a consistent IP address is not necessary. An example of this would be the IP address your ISP (internet service provider) assigns you when you log on to the internet. You must have an IP address to surf the web but once you disconnect you loose that address. Then the next time you sign on you are assigned a new one. This is done using DHCP.
Question No: 21 ( Marks: 5 )
What is cryptography? What techniques are used for cryptography?
An investment in knowledge always pays the best interest
Cryptography is the technique of converting a message into unintelligible or non-understandable form such
that even if some unauthorized or unwanted person intercepts the message he/she would still not be able to
make any sense out of it. Cryptography is thousands of years old.
Techniques used for cryptography Substitution In substitution we replace each letter in the message with
another to make the message non-understandable. For example, each letter “a” in the message can be
replaced with letter “d” and letter “b” with letter “e” and so on. Transposition It is based on scrambling the
characters in a message. A transposition system may first write a message into a table row by row then the
message can be read and rewritten column by column to make it scrambled.
