This article highlights why PowerShell logging is a critical foundation for modern detection, serving as the second most important data source according to MITRE ATT&CK. While standard process creation events show that PowerShell ran, they often fail to capture the actual content of obfuscated or in-memory commands. By enabling enhanced logging, security teams can gain visibility into script execution that leaves no trace on the physical disk.
The guide breaks down the three pillars of PowerShell logging: Module Logging (Event ID 4103), Script Block Logging (Event ID 4104), and Transcription. Script Block Logging is identified as particularly powerful because it captures code at the time of compilation, allowing analysts to see through layers of obfuscation and identify malicious payloads even when attackers use sophisticated evasion techniques.
Finally, the technical walkthrough provides implementation steps via Group Policy, Registry, and JSON configuration for PowerShell 7. It offers practical advice on managing log volume, setting retention policies, and correlating PowerShell events with other security logs to build robust detection logic for common threats like credential access, reconnaissance, and download cradles.
