Network security refers to the practices, technologies, and policies designed to protect networks, devices, and data from cyber threats, unauthorized access, and attacks. It ensures confidentiality, integrity, and availability of information while preventing risks like data breaches, hacking, malware, and phishing.

Key Aspects of Network Security:
✅ Encryption (TLS, SSL) – Protects data in transit by making it unreadable to attackers.
✅ Firewalls & Intrusion Detection – Monitors and filters traffic to block unauthorized access.
✅ Authentication & Access Control – Uses passwords, biometrics, and multi-factor authentication (MFA) to verify users.
✅ Secure Communication (HTTPS, VPNs) – Ensures that sensitive information remains private online.
✅ Regular Security Updates – Keeps software and hardware protected from vulnerabilities.
