Network Access Control

Network Access Control (NAC) is a security method that manages and enforces who and what can connect to a computer network. It ensures devices meet specific security standards before granting access, such as having up-to-date software or security features. NAC helps prevent unauthorized devices from accessing sensitive information, reducing the risk of cyber threats. Think of it as a gatekeeper that checks if a device is secure and authorized before allowing it to join the network, maintaining overall safety and integrity of the system.
