Episode 13 — Make external threat feeds actually pay off
External threat feeds are often a major investment for security teams, but they only provide value if they are correctly integrated and operationalized within the local environment. This episode teaches you how to "curate" commercial and open-source feeds, ensuring that the indicators of compromise (IOCs) you ingest are relevant to your specific industry, geography, and technology stack. We discuss the danger of "IOC bloat," where an overwhelming number of low-fidelity indicators lead to alert fatigue and wasted investigative resources. A best practice is to use these feeds not just for blocking, but as a starting point for "proactive hunting" to find existing infections that your automated tools may have missed. In a GCTI context, you must demonstrate the ability to evaluate a feed’s quality and to "contextualize" its data by linking it to known adversary campaigns or TTPs.
