What methods are used to prevent network threats and attacks?

Preventing network threats and attacks is achieved through a combination of methods and tools:

• Firewalls: Filtering incoming and outgoing traffic based on rules.
• Intrusion Detection and Prevention Systems (IDS/IPS): Analyzing traffic to detect suspicious activity and block attacks.
• Traffic encryption: Using TLS/SSL protocols to protect data during transmission.
• Authentication and authorization: Controlling access to network resources.
• Updates and patching: Regularly updating software to fix vulnerabilities.
• Network segmentation: Dividing the network into zones with different trust levels.
• Monitoring and logging: Tracking events and analyzing them for quick response.

For example, configuring a firewall to block unauthorized ports and using VPNs for secure access to the corporate network are basic security measures.
