Network Security refers to any activities that take place to protect the network; more likely to protect the usability, reliability, integrity, and safety of the network and data. Targeting the threats and stopping them to enter or spread on the network is the job of effective network security. Most common threats for any computer networks are: • Viruses, worms, and Trojan horses • Spyware and adware • Hacker attacks • Identity theft • Data interception To prevent these threats, multiple layers of security need to be implemented so if one fails, other stand.

Thus, users should be cautious at their side to protect their network by regularly scanning the computer against viruses, using firewall and be careful towards identity and data
