Lab04: NSA Codebreaker Challenges
=================================

The Department of Homeland Security (DHS) has requested NSA's 
assistance in investigating unusual network activity within a 
large SCADA system. The system controls critical infrastructure 
for multiple cities, so it's imperative that an assessment is 
carried out immediately. If any intrusions are found, then we 
need to identify how the systems were compromised and neutralize 
the threat. DHS is concerned that someone might be attempting 
to take control of the distributed sensor nodes and form a large 
botnet. If this happens, they could use it to wreak havoc across 
the cities and potentially launch DDoS attacks against other 
critical networks. We need your help to stop this from happening! 

There are six different levels or "tasks" to the challenge, with each
one being progressively more difficult and building off of the
previous tasks. The basic goal of each task is as follows:

* Problems

  - Task 1: Analyze suspicious network traffic
  - Task 2: Develop a network signature for an intrusion detection system
  - Task 3: Analyze critical system components for vulnerabilities (1)
  - Task 4: Analyze critical system components for vulnerabilities (2)
  - Task 5: Perform forensic analysis of a compromised endpoint
  - Task 6: Craft an exploit to takedown the botnet server and devise 
            a strategy to clean the infected endpoints
