What are the types of network security?

Network security typically consists of several primary categories that work together to safeguard organizational systems:

1. Access Control: Access control mechanisms restrict who can access the network and resources within it, often based on user authentication, authorization levels, and encryption. This helps prevent unauthorized users from gaining access and protects against misuse of resources.

2. Firewalls: Firewalls are a crucial part of network security that monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between internal networks and external entities, filtering harmful traffic and preventing unauthorized access.

3. Intrusion Detection and Prevention Systems (IDPS): IDPS monitor network traffic for signs of malicious activities or security threats. They can detect and respond to security incidents in real-time, helping to defend against various types of attacks.

4. Network Segmentation: Network segmentation involves dividing a network into smaller subnetworks to isolate and restrict access between different parts of the network. This limits the potential impact of security breaches and helps contain threats within specific segments.

5. Encryption: Encryption techniques are used to secure data in transit and at rest by converting it into an unreadable format that can only be deciphered with the appropriate keys. This helps protect sensitive information from unauthorized access or interception.

6. Security Information and Event Management (SIEM): SIEM tools collect and analyze security event data from various network sources to identify potential security incidents and provide insights for incident response and threat management.
