Network security refers to the practice of protecting computer networks and their data from unauthorised access, misuse, or disruption. It involves implementing various measures to ensure that only authorised users can access the network and its resources while keeping out intruders and malicious attackers.

Think of network security as protecting your home. You install locks on doors and windows to keep burglars out, and you might have security cameras or alarms for added protection. Similarly, in a computer network, you use tools like firewalls, antivirus software, encryption, and strong passwords to safeguard against cyber threats and keep your data safe from hackers and cybercriminals.

Network security is all about keeping your digital "home" safe from unwanted visitors and potential threats.
