Episode 111: Indicators of Compromise (IoCs) – Detection Foundations

Detecting an attack starts with recognizing the signs. In this episode, we explore Indicators of Compromise (IoCs)—artifacts that suggest an organization may have been breached or is under active threat. You’ll learn how IoCs include file hashes, domain names, IP addresses, registry keys, and behavioral anomalies, and how analysts discover them during investigations or receive them through threat intelligence feeds.

We’ll also discuss how IoCs are categorized, how they are validated, and how they’re fed into SIEMs, firewalls, and endpoint detection platforms to prevent future occurrences. Understanding IoCs is not just about knowing what to block—it’s about knowing what to look for, how to trace a threat’s origin, and how to build alerts that actually matter. This episode arms you with foundational knowledge that ties directly into multiple CySA+ domains and daily SOC operations. Brought to you by BareMetalCyber.com
