List 3 best practices when attempting to identify and fix a network issue.
1.Get the right information
2.Keep it Simple: Check the obvious first; power, connections, cables etc.
3.Establish what has changed
4.Test the results
5.Document the solution
This is a process of information gathering, in which the attacker attempts to learn about the configuration of the network and security systems.
Footprinting
This protocol delivers status and error messages and is used by diagnostic utilities.
Internet Control Message Protocol (ICMP)
