CTCH 655 at the University of Maryland Global Campus teaches graduate students to use technology that spots, records and prioritizes cyberattacks.
UMGC describes it as the study and application of technological solutions that identify, catalog and triage cyberattacks. Topics include host-based monitoring, auditing, network intrusion detection and prevention, and report generation tools, all taught in a lab-intensive environment.
Students often find the volume of data the hardest part. Logs and alerts are plentiful; deciding which ones matter, and explaining why, is the real skill.

What CTCH 655 Covers
| Topic | In plain language |
|---|---|
| Host-based monitoring | Watching activity on individual computers and servers |
| Auditing | Recording and reviewing who did what, and when |
| Network intrusion detection | Spotting suspicious traffic on the network |
| Intrusion prevention | Blocking suspicious traffic automatically |
| Triage | Sorting alerts by urgency and likely impact |
| Report generation tools | Turning raw data into findings people can act on |
Key Concepts Explained
Detection Versus Prevention
An intrusion detection system (IDS) alerts on suspicious activity; an intrusion prevention system (IPS) sits in the traffic path and can block it. Prevention is stronger but riskier, because a wrong rule can block legitimate business traffic.
Signature and Anomaly Detection
Signature detection matches known attack patterns and produces few false alarms, but misses new attacks. Anomaly detection flags unusual behavior against a baseline and can catch new attacks, but generates more false positives.
Triage
Triage means deciding what to investigate first. Useful questions are: how critical is the asset, how reliable is the alert, and is there corroborating evidence elsewhere?
Example: Three alerts arrive: a port scan from the internet against the web server, repeated failed logins on a test machine, and a domain controller connecting to an unfamiliar external address. The scan is common background noise. The failed logins matter but involve a low-value host. The domain controller's outbound connection gets top priority, because the asset is critical and the behavior suggests possible command and control.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Tool configuration lab | Setting up monitoring correctly | Document settings and why you chose them |
| Alert or log analysis | Interpreting events | Separate true positives from noise, with reasons |
| Audit report | Reviewing controls and records | State criteria, evidence, findings and fixes |
| Monitoring strategy | Designing coverage | Map key assets to the data sources that watch them |
Auditing: Criteria, Evidence and Findings
Monitoring watches activity as it happens; auditing checks, after the fact, whether controls worked and rules were followed. CTCH 655 covers both, and assignments often ask you to connect them.
An audit finding has a standard shape that reviewers expect:
- Criteria: the rule or standard, such as a policy requiring account lockout after failed logins.
- Condition: what you actually found in the logs or settings.
- Cause: why the gap exists, for example a misconfigured group policy.
- Effect: the risk the gap creates.
- Recommendation: a specific, testable fix.
Example: Criteria: privileged logins must be logged and reviewed weekly. Condition: audit logging is disabled on two of five servers. Cause: a new server template omitted the setting. Effect: privileged misuse on those servers would go unseen. Recommendation: update the template, enable logging and forward events to the central log server.
Where Students Get Stuck
- Treating every alert as an incident. Show your triage reasoning instead.
- Screenshots with no interpretation. Explain what each event means.
- No baseline. Anomalies only make sense against normal activity; describe what normal looks like.
- Weak recommendations. Suggest specific tuning, rules or coverage changes.
Study Tips for CTCH 655
- Learn the main log sources: operating system event logs, firewall logs, authentication logs and IDS alerts.
- Keep a simple triage checklist: asset value, alert confidence, corroboration, action.
- Record every configuration change in labs so your report can be reproduced.
- Use MITRE ATT&CK technique names to describe suspicious behavior precisely.
