Lesson 4 • Malware Categories and Behavior
Covers viruses, worms, ransomware, spyware, and rootkits. Explains how each propagates and what damage it causes.
Lesson 5 • Advanced Persistent Threats
Explains multi-stage, long-dwell intrusion campaigns. Students understand how APTs differ from opportunistic attacks.
Chapter 4HideHide detailsSee detailsAttack Lifecycle and Adversary Tactics
Attack Lifecycle and Adversary Tactics
Lesson 1 • Reconnaissance and Footprinting
Details passive and active information-gathering methods attackers use before striking. Connects open-source intelligence to attack planning.
Lesson 2 • Exfiltration and Impact Techniques
Examines how attackers extract data and cause damage at campaign end. Students recognize indicators of exfiltration in logs.
Lesson 3 • Exploitation and Privilege Escalation
Covers how attackers leverage vulnerabilities to gain and expand access. Builds understanding of post-exploitation goals.
Lesson 4 • The Cyber Kill Chain Model
Breaks intrusions into seven sequential phases from reconnaissance to actions on objectives. Enables defenders to identify intervention points.
Lesson 5 • MITRE ATT&CK Framework Basics
Introduces tactics, techniques, and procedures organized in the ATT&CK matrix. Students navigate the matrix to describe adversary behavior.
Chapter 5HideHide detailsSee detailsVulnerability Assessment and Management
Vulnerability Assessment and Management
Lesson 1 • Continuous Vulnerability Monitoring
Introduces ongoing scanning cadences, threat intelligence feeds, and metrics. Builds a proactive rather than reactive security posture.
Lesson 2 • Common Vulnerability Scoring and Databases
Explains CVSS scoring, CVE identifiers, and the NVD. Students use scores to compare and prioritize vulnerabilities objectively.
Lesson 3 • Vulnerability Scanning Fundamentals
Introduces authenticated vs. unauthenticated scans and common scanning tools. Students configure and interpret basic scan results.
Lesson 4 • Patch Management and Remediation
Covers patch testing, deployment pipelines, and compensating controls. Students design a repeatable remediation cycle.

Lesson 2 • Data Protection and Encryption Controls
Explains encryption at rest, in transit, and key management practices. Protects data confidentiality against interception and theft.
Lesson 3 • Identity and Access Management
Explains multi-factor authentication, least privilege, and privileged access management. Reduces credential-based attack success.
Lesson 4 • Security Information and Event Management
Covers SIEM architecture, log ingestion, correlation rules, and alerting. Students build a basic detection use case.
Lesson 5 • Endpoint Protection Strategies
Covers antivirus, EDR, application whitelisting, and host hardening. Connects endpoint controls to malware and exploitation defense.
