Instructor comments: While I could tell the instructor was very knowledgeable, his instructions were not very clear. He could've done a better job preparing for the class.
Facilities comments: Room was fine. The location of the room could have been better as the dings from the elevator were a bit distractive.
User: TracyPaul
Instructor comments: Very knowledgeable. Diagnosed our programming problems in short order. Could go into the details of 'why', versus only the 'how'.
Facilities comments: Outstanding. The hotel staff did a great job supporting our class.

Course Overview:
This course is instructed with an instructor in the classroom with provided lab equipment and Cyber Range.
Students enrolled in the Certified Network Defender course, will gain a detailed understanding and hands on ability to function in real life situations involving network defense. They will gain the technical depth required to actively design a secure network in your organization. This program will be akin to learning math instead of just using a calculator.
This course gives you the fundamental understanding of the true construct of data transfer, network technologies, software technologies so that you understand how networks operate, understand what software is automating and how to analyze the subject material.
You will learn how to protect, detect and respond to, and predict threats on the network. This builds upon the typical knowledge and skills of Network Administrators in network components, traffic, performance and utilization, network topology, system locations, and security policies.
You will learn network defense fundamentals, the application of network security controls, protocols, perimeter appliances, secure IDS, VPN and firewall configuration. You will then learn the intricacies of network traffic signature, analysis and vulnerability scanning which will help you when you design greater network security policies and successful incident response plans. These skills will help you foster resiliency and continuity of operations during attacks.
This course supports a certification that is DoD approved 8570 Baseline Certificate and meets DoD 8140/8570 training requirements.
What’s Included:
- EC-Council official E-Courseware
