Shifting from reactive to proactive: Cyber resilience amid nation-state espionage

This article argues that adversaries such as China-linked Salt Typhoon are shifting from hardened endpoints to neglected perimeter devices (routers, VPNs, firewalls), exploiting unpatched and end-of-life systems and using living-off-the-land tactics for persistent espionage. It urges organizations to master fundamentals—comprehensive asset/lifecycle management, prompt patching with secure baselines, credential rotation after suspected compromise, centralized logging with egress monitoring, and proactive threat hunting—aligning to the NIST Cybersecurity Framework to build a resilient, full-spectrum cyber defense posture.
