Network security ensures the protection of digital infrastructure by safeguarding systems, data, and devices from cyber threats. Key strategies include:
- Firewalls: Monitor and control incoming/outgoing traffic.
- Encryption: Secure data during transmission and storage.
- Authentication: Verify users through passwords, biometrics, or multi-factor authentication (MFA).
- Intrusion Detection Systems (IDS): Detect unauthorized activities.
- Access Control: Limit system access based on roles and privileges.
Regular updates, employee training, and proactive monitoring are essential to defend against malware, ransomware, and phishing attacks.
