CS610 GDB No. 1 Spring 2020 Due date 19-08-2020
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?

#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)
