TN-865: Wireshark Network Traffic and Security Analysis

Course Overview:

This course delivers the technical knowledge, insight, and hands-on training to receive in-depth knowledge on Wireshark® and TCP/IP communications analysis. You will learn to use Wireshark to identify the most common causes of performance problems in TCP/IP communications. You will learn about the underlying theory of TCP/IP and the most used application protocols, so that you can intelligently examine network traffic for performance issues or possible Indicators of Compromise (IoC).

Duration: 5 Days

Audience:

Anyone interested in learning to troubleshoot and optimize TCP/IP networks and analyze network traffic with Wireshark, especially network engineers, information technology specialists, and security analysts.

CT-225: Network+

Course Overview:

CT-225: Network+ is a five-day course that teaches students the fundamentals of networking. Through hands-on training, students learn the vendor-independent networking skills & concepts that affect all aspects of networking, such as installing & configuring the TCP/IP client. The course also helps to prepare students for three popular certification examinations: CompTIA Network+, Microsoft Networking Essentials, and Novell Networking Technologies.

Attendees to CT-225: Network+ will receive TechNow approved course materials and expert instruction.

Instructor comments: Great instructor.

Facilities comments: BEST HOTEL!!!!!!! AMAZING LOCATION, GOOD FOOD, NICE SPACE. The location of the hotel is what is almost the best about it. Driving up hwy 10 in the morning is absolutely awful.

Like the class? Then let everyone know!

Virtualization/Cloud

TechNow has been involved in enterprise client server architectures since 1990. TechNow has delivered national and international implementations for Valero, Wholefoods, Quest, USAA, Golfsmith, AMD, Motorola, and many other fortune 1000 corporations,

TechNow's training program has followed the evolution of enterprise computing into virtualization and cloud computing. With a focus on security, TechNow can present the ramifications of many centralized strategies. All courses utilize enterprise instructors with experience and can discuss the detail of implementation and the integration into an existing infrastructure.

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.
