Explain the concept of network security.

Network security refers to the measures and practices implemented to protect a computer network and its data from unauthorized access, misuse, modification, or disruption. It involves the use of various protocols, technologies, and strategies to ensure the confidentiality, integrity, and availability of network resources. Network security aims to prevent unauthorized access to sensitive information, detect and respond to security incidents, and minimize the potential risks and vulnerabilities within a network. This includes implementing firewalls, encryption, access controls, intrusion detection systems, and regular security audits to safeguard the network infrastructure and maintain a secure environment for users and data.
