Network security protects your company's network to avoid unwanted security breaches, threats, and intrusions. It is the protection provided to the underlying networking structure from any unauthorized access, misuse, or theft. It involves access controls, application security, firewalls, virus and antivirus software systems, network analytics, VPN encryption, etc. It effectively combines multiple layers of defenses in the network and edge. It implements the controls and policies that can block the malicious entries and activities from carrying out any exploits on your network. Network security, therefore, helps in protecting proprietary information from any attack.
