Question

Please list and explain some examples of how network integrity and availability can be compromised?

Answer 1

Integrity

1) Salami attacks:

These are a series of minor data security attacks that together result in a larger attack.

Example: Extracting a small amount from your bank account which you cannot notice. But when this small amounts of deduction is done from large number of accounts, it will be a huge amount.

Avilability

1) DOS:

DOS polularly called as Denial of Service Attacks. It is a attack to a network server with huge number of service requests which cannot handle. Which causes the server to crash.

2) DDOS:

DDOS is known as Distributed Denial of Service Attacks. It is originated from many attacking computers from different geographical regions like DOS.

3) SYN flood attacks:

In this attacker sends many TCPSYN packets to initiate a TCP connected, but never send a SYN - ACK pack back.

4) ICMP flood attacks:

In this the victim computer is sent with many false ICMP packets.
