30 minutes
Dynamic Malware Analysis
Students will use utilize two virtual machines, inside a protected network, to observe configuration changes on a known good / clean system and all of the unusual network traffic generated by the suspect software they will be analyzing. On the clean system they will use Regshot, Argon Network Switcher, Process Hacker, Process Monitor and Noriben to gather details on what the suspicious program is actually doing. On another support machine they will set up a fake DNS server to receive all suspicious traffic, and pass that traffic over to Wireshark for further analysis. This lab will continue to foster tool familiarization and will provide the students an introduction to capturing network traffic by using a simple “man-in-the-middle” system.
1 hour
Denial of Service PCAP Analysis
The student will act as attacker and defender in this scenario. They will receive experience using a custom denial of service python script, and then will switch over to the defensive side.

System Hardening – Scored
A number of technologies exist that work together to protect systems and networks. The real value of your networks and systems rests in the data that networks carry and reside in systems. In this lab you will focus on some ways you can safeguard the data that resides on systems and when data is sent across the network. Securing an operating system, also known as hardening, strives to reduce vulnerabilities in order to protect a system against threats and attacks.

1 hour
Event Log Collection
In this lab you will use Splunk Enterprise to ingest logs from a local host for analysis.
1 hour
Securing Linux – Firewalls
Firewalls are an important part of limiting network traffic. Properly implemented firewalls can greatly limit the amount of damage an attacker can do by enforcing access control on the network interface. They can also be incredibly useful for regulating the amount of traffic or allowing certain network translations to occur that provide extra functionality.
1 hour
Use pfTop to Analyze Network Traffic – Scored
Students will use pfTop, a network traffic monitoring/statistics plugin used in pfSense, to analyze and monitor network traffic.

Students will then investigate and correlate system logs to identify missing patches, level of access obtained, unauthorized processes or programs.
38 minutes
Protect Against Beaconing
Students will take a PCAP indicating the presence of a beacon on the network and analyze it. The analysis will determine if there’s activity that we can mitigate mitigation and then implement a Firewall block with logging to prevent future beaconing.
