What is Network security?

• A. Measures for protecting a computer network from intruders, including both wired and wireless connections.
• B. The practice of securing a single computer.
• C. The process of backing up data to the cloud.
• D. The management of user credentials.

Answer: (A)

Network security is the set of measures that protect a computer network from intruders, covering both wired and wireless connections. It involves safeguarding the devices that make up the network (like routers, switches, and wireless access points), protecting data as it moves across the network, and controlling who can access network resources. Techniques such as firewalls, encryption, secure configurations, authentication and access controls, intrusion detection and prevention systems, and continuous monitoring work together to prevent unauthorized access, data theft, and service disruption. The aim is to secure the network as a whole, not just individual machines. Think of it as safeguarding the pathways and devices that let computers talk to each other and share information, rather than only protecting a single computer. For contrast, protecting a single computer is endpoint security, backing up data to the cloud is data protection and disaster recovery, and managing user credentials is identity and access management.
