Briefly describe the following types of attacks: DoS, man-in-the-middle, and IP service.

Question

What will be an ideal response?

Answer 1

In a DoS attack, a service is inundated with service requests, or malformed service requests cause a server to hang. In either case, legitimate users are denied access to a server's services because it is kept completely busy or becomes unavailable.
In a man-in-the-middle (MITM) attack, the attacker is able to intercept traffic from both parties and either pass the traffic unaltered to the other end of the communication link, or the attacker can forge replies from either side.
Numerous IP services are subject to attack (IP service attacks), often through their well-known ports (but sometimes through other ports as well) in ways that can expose the underlying systems to inspection or manipulation, particularly when the underlying file system is accessible.
