A computer network connects devices like computers and smartphones, enabling data sharing. These networks can be local (LAN) or wide-reaching (WAN), with the Internet being the largest example.

Network security is crucial for protecting data from unauthorized access, cyber-attacks, and breaches. Key components of network security include:

Firewalls: They filter incoming and outgoing traffic, blocking unauthorized access.

Encryption: It scrambles data, ensuring privacy by making it unreadable to unauthorized users.

Authentication and Access Control: These methods verify the identity of users, allowing only authorized access.

IDS/IPS: Intrusion Detection and Prevention Systems monitor and block suspicious activities.

VPN (Virtual Private Network): A VPN encrypts the internet connection, ensuring secure online activity, especially on public networks.

Effective network security is vital to protect sensitive data, prevent cyber-attacks, and maintain safe communication in a connected world.
