CTCH 615: Cybersecurity Threats and Analysis

CTCH 615 at the University of Maryland Global Campus teaches you to understand threats systematically: who threatens an organization, how exposed it is and why security fails.

UMGC describes it as an introduction to the tools and tactics used to manage threats, identify common threat types, analyze organizational exposure, and collect and analyze cybersecurity intelligence. The goal is to analyze common security failures and identify the specific design principles that were violated.

Emphasis is on the interaction between security and usability, and on minimizing potential harm from modern threats, attacks and usability challenges. It is a 3-credit graduate course; students may receive credit for only one of CST 610 or CTCH 615.

What CTCH 615 Covers

• Threat management tools and tactics: how organizations track and respond to threats.
• Common threat types: malware, phishing and social engineering, insider threats, denial of service and more.
• Exposure analysis: working out which assets are at risk and how reachable they are.
• Threat intelligence: collecting and analyzing information about attackers and their methods.
• Security failures and design principles: tracing breaches back to violated principles.
• Security and usability: why controls people work around are not really controls.

Key Concepts Explained

Secure Design Principles

Classic principles, such as those set out by Saltzer and Schroeder, give a vocabulary for explaining failures: least privilege, fail-safe defaults, economy of mechanism, complete mediation, separation of privilege and psychological acceptability, among others.

Usability as a Security Property

Psychological acceptability means security must be easy enough that people use it correctly. Password rules so strict that staff write passwords on notes, or alerts so frequent they are ignored, create new weaknesses. UMGC's emphasis on usability reflects this.

Threat Intelligence Levels

Intelligence is often described at strategic (trends for leaders), operational (campaigns and actors) and tactical (indicators such as malicious IP addresses or file hashes) levels. Good reports match the level to the audience.

Typical Assignments and How to Approach Them

Where Students Get Stuck

• Describing the attack only. Marks come from explaining why it worked and which principle failed.
• Unreliable sources. Prefer official advisories, vendor research with clear methods and scholarly work.
• Ignoring people. Many failures are human or usability failures, not purely technical ones.

Study Tips for CTCH 615

• Memorize the main design principles with one example each.
• Read public post-incident reports and practice naming the violated principles.
• Follow official advisories from national cybersecurity agencies to see intelligence written for different audiences.

Analyzing Organizational Exposure

Exposure analysis asks how reachable and attractive an organization's assets are to the threats you have identified. A structured approach keeps it manageable:

1. List critical assets (data, systems, services) and their value to the organization.
2. Identify which are exposed: internet-facing systems, third-party connections and remote access routes.
3. Match likely threat actors and techniques to those exposed assets.
4. Rate each combination by likelihood and impact, and recommend reductions in exposure.

Frameworks such as MITRE ATT&CK can help describe attacker techniques consistently, which makes your analysis easier to follow and compare.

How We Help with CTCH 615

Send the assignment, rubric, case material and earlier feedback. A tutor can explain design principles and threat analysis methods, prepare a model case study for reference, or edit your paper for depth, clarity and APA style.
