GDB Topic

ICMP handles error and control messages and are very useful especially when an error occurs in WAN. ICMP messages are encapsulated and sent within IP datagrams while specific hosts and routers use ICMP to send reports of problems about the datagrams. There are several different types of ICMP messages depending on what the ICMP message is reporting. However, malicious users have found a way to turn a good network into an attack through which attacker attempts to disrupt a target machine causing the target machine to become inaccessible to normal traffic.



(A) In your opinion which type of attack from the following can become the cause of inaccessibility of the target machine? Justify your answer with sold reason in maximum five lines.

1: Ping of Flood

2: Ping of Death

(B) ICMP can also be used to test different tools. In your opinion, which are the 2 most common tools that use ICMP for basic management and troubleshooting on a network?



Instructions:

Please read the following instructions carefully before submitting the GDB:

A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 4-5 lines.

Solution :






#CS610 #GDB Idea from some one

According to my point of view the Ping of Death will cause of inaccessibility of the target machine. Because Ping of Death is a Denial of Service (DoS) attack in which no need of detailed knowledge of the machine intruder was attacking, except for its IP address. Ping of Death attacks were particularly effective because the attacker's identity could be easily spoofed. While in Ping of Flood attacker's need more bandwidth than victim and more knowledge about network.
(B) ICMP can also be used to test different tools. In your opinion, which are the 2 most common tools that use ICMP for basic management and troubleshooting on a network?
The ICMP used for the following most Common Test
1. TEST REACHABILITY (Specific Command Ping or Echo)
2. USING ICMP TEST TO TRACE A ROUTE (Specific Command Trace route or Tracert)
