Network Security

What Is Network Security?

Network security is the practice of protecting networks, systems, and programs from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. It also involves preventing and detecting unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources.

Usage and Examples

Network security is used to protect networks, systems, and programs from digital attacks. Common examples of network security measures include firewalls, antivirus software, intrusion detection systems, and encryption. Firewalls are used to block unauthorized access to a network, while antivirus software is used to detect and remove malicious software. Intrusion detection systems are used to detect suspicious activity on a network, while encryption is used to protect data from being accessed by unauthorized users.
