Here’s an overview of both concepts:

Network Security

1. Firewalls:
   • Devices or software that filter incoming and outgoing traffic to prevent unauthorized access.
2. Intrusion Detection and Prevention Systems (IDPS):
   • Monitors network traffic for suspicious activities and can take action to block potential threats.
3. Endpoint Security:
   • Protects devices connected to the network (like computers and smartphones) from malware and other threats.
4. Virtual Private Networks (VPNs):
   • Encrypts internet traffic and ensures secure remote access to the network.
5. Access Control:
   • Implements policies to control who can access what resources within the network, using authentication and authorization methods.
6. Encryption:
   • Protects data in transit and at rest to prevent unauthorized access or breaches.
7. Security Information and Event Management (SIEM):
   • Collects and analyzes security data from across the network to identify and respond to threats.

Health Monitoring

1. Network Performance Monitoring:
   • Tools that track network traffic, bandwidth usage, and performance metrics to ensure optimal operation.
2. Availability Monitoring:
   • Ensures that network devices and services are operational, alerting administrators to outages or performance degradation.
3. Configuration Management:
   • Monitors changes in network configurations to detect unauthorized alterations that could indicate security issues.
4. Log Management:
   • Collects and analyzes logs from various devices for troubleshooting and security incident analysis.
5. Real-time Alerts:
   • Systems that notify administrators of critical issues, enabling prompt action to mitigate problems.
6. Regular Audits and Assessments:
   • Conducting routine security assessments and health checks to identify vulnerabilities and areas for improvement.
