Network security refers to the set of procedures, programs, and technologies an organization uses to ensure the safety of the computers and the integrity of data in its network. Having a secure network translates to keeping users safe from cyber attacks and ensuring that programs and tools perform their functions well.

You can think of a network security as the armed forces of your computer systems. Armed with state-of-the-art weapons, your forces are always on high alert and ready to defend your computing resources from attackers.
