Network Monitoring and Security Best Practices: A Comprehensive Guide
Explore essential frameworks, best practices, and secure network architecture concepts to monitor and diagnose networks effectively. Learn about ISO standards, NIST guidelines, PCI-DSS, and OWASP recommendations for secure systems design. Discover secure staging deployment concepts including network segmentation, honeypots, and VPN tunneling. Enhance your understanding of security devices like firewalls, SDN, and IDS/IPS to bolster network security.

CompTIA Security+ Study Guide (SY0-501) Chapter 2: Monitoring and Diagnosing Networks
Chapter 2: Monitoring and Diagnosing Networks Explain use cases and purpose for frameworks, best practices, and secure configuration guides Given a scenario, implement secure network architecture concepts Given a scenario, implement secure systems design Explain the importance of secure staging Deployment concepts
Frameworks, Best Practices, and Configuration Guides ISO Standards North American Electric Reliability Corporation (NERC) National Institute of Standards and Technology (NIST) ISA/IEC-62443 Payment Card Industry Data Security Standard (PCI-DSS)
Payment Card Industry Data Security Standard (PCI-DSS)
Open Web Application Security Project (OWASP) 1. Verify for security early and often 2. Parameterize queries 3. Encode data 4. Validate all inputs 5. Implement identity and authentication controls 6. Implement appropriate access controls 7. Protect data 8. Implement logging and intrusion detection 9. Leverage security frameworks and libraries 10. Error and exception handling
Secure Network Architecture Concepts Zones Demilitarized zone (DMZ) Extranet and intranet Wireless
Honeypots and Honeynets Honeypot: A separate system that appears to be an attractive target but is in reality a trap for attackers Honeynet: A fake network segment that appears to be a very enticing target (a logical extension of a honeypot)
Security Devices Firewalls Software-defined networking (SDN) IDS/IPS
Secure Systems Design Hardware and firmware Operating systems Peripherals
