Network security is a set of measures to protect a computer network from unauthorized access, misuse, and malicious activities. It involves the authorization of access to data in a network, which the network administrator controls. Standard security measures include firewalls, virtual private networks (VPNs), data encryption, and user authentication. Network security also includes monitoring and controlling network traffic to detect malicious activities and protect against malicious attacks.
 

Network security is becoming increasingly popular because of the growing number of cyber-attacks and data breaches that organizations and individuals face. Networks are becoming increasingly interconnected, and as a result, they are more vulnerable to malicious attacks. 

Network security is crucial because it helps protect networks from unauthorized access, malicious attacks, and data theft. It also helps to ensure the integrity of data and system resources and can help protect against the theft of intellectual property and other sensitive information.
