This course is dedicated to network security, one of the most comprehensive chapters in the curriculum. Covering approximately 3 hours of expert instruction, learners develop a solid understanding of how to design, implement, and operate a secure network infrastructure.
Learners benefit by gaining knowledge of network security zones, firewall architecture, network access control, intrusion detection and prevention, VPN technologies, and network monitoring and hardening techniques. Online labs reinforce firewall configuration, VPN setup, and network security monitoring tasks. This course directly covers the Security Architecture and Security Operations domains of the exam. By the end of this course, learners will be able to design and implement secure network architectures and apply monitoring and response techniques to defend enterprise networks.
This chapter highlights data states, key protection, encryption concepts, certificate use, trust models, network layers, segmentation choices, access controls, proxy functions, tunneling security, and detection techniques.
