Explanation
Plan to defend your network against different types of DoS attacks:
* Application-Based Attacks
-Target weaknesses in a particular application and try to exhaust its resources so legitimate users can't use it.
An example of this is the Slowloris attack.
* Protocol-Based Attacks
-Also known as state-exhaustion attacks, these attacks target protocol weaknesses. A common example is a SYN flood attack.
* Volumetric Attacks
-High-volume attacks that attempt to overwhelm the available network resources, especially bandwidth, and bring down the target to prevent legitimate users from accessing those resources. An example of this is a UDP flood attack.
