CellStream, Inc. – Telecom Consulting and Training!
2-Day Instructor Led Hands On Lab Class
Network security protocols are designed to ensure privacy and integrity of data that is transitioning our networks, and prevent unauthorized access. They define the processes and message exchanges to protect networks from illegitimate attempts to capture and extract meaningful information about the network or the data being carried over the network.
This course shows the learner how to use Wireshark to further their understanding of commonly deployed network security protocols that are deployed in IP networks today. Security protocols covered in in this course include: Telnet and SSH, TLS both the legacy versions and the new version 1.3, key IPsec protocols, which includes IKE, ISAKMP, AH, and ESP, and 802.1X port-based access control, which encompasses RADIUS, EAP, and EAPoL.
This course shows the student how to use Wireshark to capture traffic and identify the security protocols that are being implemented in the network. This course will also highlight key capabilities in Wireshark that can be used to analyze and troubleshoot network traffic to identify security issues. This includes defining Wireshark security profiles, using Wireshark capture and display filters to identify protected and unprotected traffic, coloring rules, and using relevant Wireshark statistical tools, in addition to how to leveraging Wireshark decryption capabilities.
The objectives of the course are:
- Understand how to identify network security protocols and mechanisms being deployed to protect network traffic
- Use the Wireshark statistical and decryption tools available to analyze network security traffic
- Develop Wireshark profiles, filters, and coloring rules to facilitate analyzing and troubleshoot network security protocols and mechanisms
- Distinguish between common security protocols being applied at the application, transport, network, and data link layers.
- Explore in detail the most common security protocols used in protecting network traffic, including SSL/TLS, HTTPS, Telnet, SSH, IPsec including IKE, ISAKMP, AH and ESP, and 802.1X, including RADIUS, EAP, and EAPoL.
- Improve the learner’s knowledge on network security and how to apply it to their job function.
This course is designed for individuals that require a deeper understanding of network security protocols, including designers, product developers, analysts, and technical support personnel. Specific use cases include:
- Security professionals that need to understand how to leverage Wireshark in their job
- Network administrator that need to understand the security mechanisms implemented in the networks they support
- Network security engineers that need to examine and investigate wireless security issues
- Developers that need to debug protocol implementations
- IT professionals that need to understand and explore network security protocol internals
This course is designed to appeal to anyone needing to further their understanding of network security. This course does not require any specific prerequisites, however knowledge of how to use Wireshark and an understanding of network security principles would be beneficial.
This is a hands-on course. Students are expected to have access to a computer that they can install the Wireshark application on. However, no prior knowledge of Wireshark is required.
Class size is limited to 20 students.
Students will be provided with a PDF Course Student Guide and PCAP files used in the hands-on labs. Students will also have access to labs and supporting material at the Online School of Network Science (www.netscionline.com).
