“Network security is any activity designed to protect the usability and integrity of your network and data, it includes both hardware and software technologies.”
Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.
Types of network security:
Antivirus and Antimalware Software
