TN-545: Certified Network Defender

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.

Observations of Instructor Led Training with Real Hardware

TechNow has heard many students talk about virtualized/remote training that TechNow Does Not Do. While training our most recent offering of PA-215: Palo Alto Networks Firewall Essentials FastTrack a student told his story of how he endend up in our course. His story we have heard for other technologies like Cisco, VMware, BlueCoat and other products.

A large percentage of training is moving to the virtualized/remote lab environments. Students are asked to use some variant of remote access software and remote into the training company's lab environment. Our student in our Palo Alto Networks Firewall course informed us that he went to a very costly offering of that course from the vendor and was not able to perform any labs. There were either network connectivity issues, or issues with the remote access software, or other problems. The whole training experience was very frustrating and not productive.

We keep our labs open to students if they would like after hours, or before hours access. Repeatedly going through a lab engrains that knowledge for later recall. Touching hardware is so critical in understanding the problems that arise when a cable comes loose, or a cable gets plugged in the wrong port. There are other scenarios such as just pulling the power cable, or turning off a power strip, or accidently overwriting a configuration. These disaster scenarious requires hands-on physical access to hardware. Preventing and recovering from disasters is what it's all about, and that requires hands-on, instructor led, real hardware.

TN-913: Cloud Security Fundamentals

Course Overview:

TechNow Cloud Security Fundamentals addresses the loss of hands-on control of system, application, and data security in the Cloud computing environment. Security teams wrestle with the impact and liability of Cloud computing on an organization. This course enables the security team to assist in contract language and Service Level Agreements (SLAs) when utilizing Cloud Service Providers (CSPs).

Compliance and auditing are introduced with strategies for control verification and audit analysis in the CSP environment. Software as a Service (SaaS) to Infrastructure as a Service (IaaS) and everything in between require a compliance strategy. Students will go in-depth into the architecture and infrastructure fundamentals for private, public, and hybrid clouds. Topics covered include: patch and configuration management, virtualization security, application security, and change management. Policy, risk assessment, and governance within cloud environments will be covered with recommendations for both internal policies and contract provisions to consider.

TechNow has worked worldwide enterprise infrastructures for over 20 years and has developed demos and labs to exemplify the techniques required to effectively manage security in the cloud environment.

Attendees to TN-913: Cloud Security Fundamentals will receive TechNow approved course materials and expert instruction.
