Overview

Setting up your network securely is the first step in preventing attacks and misuse of your resources. The labs in this category help you gain experience with common network security practices, intrusion detection systems, and firewall policies. You will gain exposure to multiple tools in order to apply your existing knowledge seeing how specific tools implement best practices and principles. Even if your network uses different software packages, the principles and procedures honed here will apply equally in your configuration.
This package includes all labs in the Secure Network Setup category, as well as all new labs in the category released during your subscription period. The MITRE ATT&CK Matrix is a taxonomy of adversary tactics and techniques, including detection and mitigation techniques for each. These techniques are aligned as appropriate to CYRIN exercise lab packages.

Outline

All CYRIN labs, exercises and attacks happen within a virtual environment. Each trainee or student gets their own virtual instance of a lab, exercise or attack, allowing training to be self-paced and available anywhere at any time. In order to meet specific training objectives, CYRIN subscriptions are sold on a packaged basis. That is, groups of CYRIN labs, exercises and/or attacks are recommended and bundled to meet the individual needs of the student.
CYRIN Secure Network Setup Package:
EXPECTED DURATION:
• 14 hours, self-paced. Pause and continue at any time.
• 14 CPEs awarded on successful completion.
• 6 months of access.
EXERCISE LAB CONTENTS:
1. Introductory IDS Configuration with Snort
Students will learn how to configure an Intrusion Detection System (IDS) to examine traffic to/from a firewall. The popular Snort® IDS will be used in this exercise. The exercise will include both harmless background traffic and potentially malicious traffic to be detected by Snort.
2. Intrusion Detection using Zeek (formerly Bro)
Students will learn how to deploy, configure and customize a Zeek Network Intrusion Detection System (NIDS). They will customize Zeek to generate enterprise specific logs and to send email notifications of events of interest. They will also create a simple Zeek plugin, using the Zeek scripting language, to detect and block brute force ssh login attempts.
3. Firewall Configuration with VyOS
Students will configure a network firewall using the VyOS router appliance, which mimics physical router hardware. The exercise will include both ingress and egress filtering, stateful packet inspection, and best practices. Students will set up a partitioned network and a DMZ area to isolate specific enterprise services, such as an e-mail server. Evaluation will include network probes from both inside and outside the firewall to ensure proper rules are configured.
4. Firewall Configuration with Iptables
Students will configure a network firewall using the standard Linux iptables module. The exercise will include both ingress and egress filtering, stateful packet inspection, and best practices. More advanced techniques such as port knocking will also be introduced. Evaluation will include network probes from both inside and outside the firewall to ensure proper rules are configured.
5. Firewall Configuration with pfSense
Students will learn to secure and configure the widely used, open-source pfSense firewall. They will learn to create firewall rules, the order in which rules are applied, how pfSense aliases can be used to simplify the pfSense rule set, and how to secure pfSense itself. They will also learn to view statistics and logs collected by pfSense.
6. VPN Server Configuration with OpenVPN
Students will learn to configure and set up an OpenVPN server. OpenVPN is an open-source virtual private network (VPN) solution. VPNs extend a private network over a public network, allowing users to send and receive data the public networks as if they are directly connected to the private network.
7. Split-Horizon DNS Configuration using BIND
Hackers shouldn’t be able to explore your internal network. To make sure they do not, you need to learn about split horizon DNS configuration. And it might help to know something about BIND, probably the most used DNS software on the internet.
NIST NICE FRAMEWORK
All of the CYRIN exercise labs are mapped to the NIST NICE Framework - Specialty Areas:
  • Network Services (NET)
  • Systems Architecture (ARC)
  • Cyber Defence Infrastructure Support (INF)
CYRIN training is sold on a subscription basis. All CYRIN subscriptions come with two free labs: “Getting Started with CYRIN” and “Web application Security Analysis using OWASP-ZAP”. All new CYRIN courses that are added to the training platform during a subscription period will be made available to subscribers at no additional cost.

How do QA’s virtual classroom courses work?

Our virtual classroom courses allow you to access award-winning classroom training, without leaving your home or office. Our learning professionals are specially trained on how to interact with remote attendees and our remote labs ensure all participants can take part in hands-on exercises wherever they are.

We use the WebEx video conferencing platform by Cisco. Before you book, check that you meet the WebEx system requirements and run a test meeting (more details in the link below) to ensure the software is compatible with your firewall settings. If it doesn’t work, try adjusting your settings or contact your IT department about permitting the website.

How do QA’s online courses work?

QA online courses, also commonly known as distance learning courses or elearning courses, take the form of interactive software designed for individual learning, but you will also have access to full support from our subject-matter experts for the duration of your course. When you book a QA online learning course you will receive immediate access to it through our e-learning platform and you can start to learn straight away, from any compatible device. Access to the online learning platform is valid for one year from the booking date.

All courses are built around case studies and presented in an engaging format, which includes storytelling elements, video, audio and humour. Every case study is supported by sample documents and a collection of Knowledge Nuggets that provide more in-depth detail on the wider processes.

When will I receive my joining instructions?

Joining instructions for QA courses are sent two weeks prior to the course start date, or immediately if the booking is confirmed within this timeframe. For course bookings made via QA but delivered by a third-party supplier, joining instructions are sent to attendees prior to the training course, but timescales vary depending on each supplier’s terms.
