About Lesson
Network security involves implementing measures to protect data and resources from cyber threats. Key components include:
Authentication:
- Verifying the identity of users or devices before granting access.
- Examples include passwords, biometrics, and two-factor authentication (2FA).
Encryption:
- Ensuring data confidentiality by converting it into unreadable formats during transmission.
- Protocols like SSL/TLS provide secure communication channels.
Access Control:
- Restricting user access to only the information and systems necessary for their role.
- Examples include Role-Based Access Control (RBAC) and Mandatory Access Control (MAC).
Network Segmentation:
- Dividing networks into smaller segments to contain potential breaches.
- Techniques include using VLANs or creating isolated zones for sensitive data.
Intrusion Detection and Prevention:
- Systems like IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) monitor network traffic for malicious activity.
These practices form the foundation of a secure network, ensuring that sensitive data and resources are protected from unauthorized access and misuse.
