Network security describes the protection of IT networks against unauthorized access, attacks or data loss.
Technical and organizational measures ensure that only authorized persons and systems can access a network. At the same time, data is protected and attacks are detected or averted at an early stage.
Typical measures include firewalls, encryption or access controls.
Practical example:
A company uses a secured WLAN with a password and additional protective measures such as a firewall. Unknown devices cannot simply connect and suspicious activities are blocked.
