MITRE ATT&CK User Discovery: Threat Detection and Defense

In modern cybersecurity, understanding how attackers explore your network is key to stopping them before they escalate privileges. Adversaries frequently use user discovery techniques to map out accounts, find high-value targets, and plan their next moves. This text-based course guides you through the foundational concepts of the MITRE ATT&CK framework, focusing specifically on user discovery techniques. You will learn to think like an attacker to identify vulnerabilities and implement robust, modern defensive strategies. What you'll learn: Understand the core principles of the MITRE ATT&CK framework and the Discovery tactic; Analyze common techniques adversaries use to discover domain and local user accounts; Identify suspicious discovery commands and behaviors in Windows and Linux environments; Apply logging and monitoring strategies to detect unauthorized user enumeration; Implement zero-trust principles and least-privilege access controls to mitigate discovery risks; Practice analyzing text-based log files and security events to spot reconnaissance activity. The course begins with foundational definitions of cybersecurity reconnaissance before moving into specific Windows, Linux, and Active Directory discovery techniques. You will then explore modern defensive strategies, threat hunting concepts, and practical log analysis exercises. This course is designed for beginner cybersecurity enthusiasts, junior security analysts, and system administrators looking to understand threat actor behaviors. No prior security experience is required. Start reading today to build your foundational threat detection skills and secure your network against unauthorized discovery.
