Good logging turns invisible activity into actionable intelligence. This episode explains what to log, where to collect it, and why retention matters. You’ll learn how system, application, and network logs each tell part of the story—and how structured, timestamped entries enable analysis across environments. The discussion clarifies core principles like completeness, consistency, and normalization, and why simply “turning on logging” is never enough. Listeners also hear how time

Log normalization and time synchronization may sound like technical housekeeping, but they’re the foundation of credible analytics. This episode unpacks how normalization translates diverse log formats into a common structure that security tools can understand. You’ll learn how field mapping, parsing, and schema alignment make search queries meaningful, enabling cross-platform correlation. The discussion also covers timestamp alignment—why even a few seconds of clock drift between devices

A Security Information and Event Management (SIEM) platform is only as valuable as the detections it produces. This episode examines how SIEM systems aggregate, correlate, and alert on log data to reveal meaningful security events. You’ll learn how analysts define use cases—structured patterns that turn raw telemetry into insights—and how correlation rules connect disparate indicators into a single narrative. The conversation highlights why tuning is critical: too many false positives erode

Dashboards transform raw data into visual understanding, and this episode explains how to design them for clarity and purpose. You’ll learn how to select metrics, define thresholds, and organize views by function—whether for SOC analysts, managers, or auditors. We discuss why dashboards should focus on signal, not noise, and how color coding, trend lines, and time windows support rapid situational awareness. The episode also connects these visualization principles to exam objectives around

This episode explores what happens after logs and evidence are collected—the policies that determine how long to keep them, how to protect them, and how to handle privacy obligations responsibly.
