NCSC’s Approach to Enhancing Cyber Resilience: Observability and Threat Hunting

The National Cyber Security Centre (NCSC) emphasises that strong cyber resilience relies on combining observability with threat hunting. Organisations must address visibility gaps across cloud, network, identity, and endpoint environments to detect threats swiftly. Key steps include enhancing telemetry, enabling cross-domain data correlation, and following standards such as RFC 9424.

Relying solely on indicators of compromise (IOCs) is no longer adequate. The focus should shift towards detecting tactics, techniques, and procedures (TTPs), which are far more difficult for adversaries to disguise. This demands comprehensive visibility, skilled analysts, and continuous, hypothesis-driven investigation.

Now, more than ever, strengthening resilience and enhancing defences against these threats is essential.
