Develop the network security and troubleshooting skills that prove a network professional's readiness for real-world work. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll learn defense in depth and how to recognize DoS and DDoS attacks, on-path attacks, VLAN hopping, malware, and social engineering. Then you'll apply logical and physical security controls, access control lists, least privilege, device hardening, and authentication methods. Finally, you'll monitor networks with baselining and alerting and follow a systematic troubleshooting methodology from symptom to root cause. Online labs reinforce attack scenarios, hardening, and troubleshooting.

Not planning to take the exam? Security and troubleshooting skills are valuable in any IT role, so they apply on the job whether or not you pursue the certification. The first module is designed as an accessible entry point, and each module builds toward the confidence to resolve complex network problems. Expert instruction keeps every topic practical. Each of the four modules builds toward real-world readiness.
