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.

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.
Prerequisites
Basic network routing concepts (firewalls, subnets, etc.) as well as basic networking concepts (TCP/IP, DNS, etc.). Students must also be comfortable working in command-line environments.
Expected Duration
2 hours, self-paced. Pause and continue at any time.

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.
Prerequisites
Basic network routing concepts (firewalls, subnets, etc.) as well as basic networking concepts (TCP/IP, DNS, etc.). Students should also be comfortable with the Linux/Unix command line.

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.
Prerequisites
Basic network routing concepts (firewalls, subnets, etc.) as well as basic networking concepts (TCP/IP, DNS, etc.). Students should also be comfortable with the Linux/Unix command line.

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.
Students will learn to set up a Certificate Authority to create the keys and certificates needed to (1) authenticate users (VPN clients) and the VPN server and, (2) encrypt communication between the two. They will also learn how to revoke client certificates when needed.
Prerequisites
Basic knowledge of public key infrastructures and certificates, and familiarity with the Unix/Linux command line.
Expected Duration
2 hours, self-paced. Pause and continue at any time.

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.
In this lab, students will configure a split-horizon DNS infrastructure that consists of two DNS servers: An External DNS server and an Internal DNS server. The External DNS lives in the organization's DMZ network; it is used by external hosts to resolve names of servers in the DMZ. The Internal DNS lives in the organization's internal network and is reachable only by hosts on the internal network. It resolves names of hosts on the internal network.
The lab uses BIND, the most popular DNS server in use today.
Prerequisites
Basic network routing concepts (firewalls, subnets, etc.) as well as basic networking concepts (TCP/IP, DNS, etc.). Students should also be comfortable with the Unix/Linux command line.

In this exercise students must configure the firewalls and routers of an enterprise network in accordance with the security policies of the organization. The computers and network devices in the network have been physically connected but the firewalls and routers have not been configured. You must configure these firewalls and routers to implement policies related to how traffic to/from the Internet and traffic between the different subnets is handled. This exercise is brought to you by the Rochester Institute of Technology-Global Cybersecurity Institute.
This exercise uses pfSense, an open-source firewall and router that is used by thousands of enterprises and officially supported by Netgate. Students must be familiar with the pfSense console and web interfaces. Those not familiar with pfSense are encouraged to complete the CYRIN Firewall Configuration with pfSense lab before attempting this exercise.
Prerequisites
Basic networking concepts including IP routing, Network Address Translation (NAT), basics of network firewalls, and familiarity with pfSense.
If you are not familiar with pfSense and its configuration, complete the CYRIN Firewall Configuration with pfSense lab before attempting this exercise.
Expected Duration
2 hours, self-paced. Pause and continue at any time.
