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.
