UK Cyber Resilience Gaps Put Focus on Security Basics, Arctic Wolf Says

· Original article ↗

Summary

Arctic Wolf’s review of NCSC findings says UK cyber resilience lags behind threats: 88% of large-organisation incidents involved four familiar routes. It recommends stronger asset, identity, patching and response practices as AI accelerates attacks.

Key points

  • The NCSC received 1,831 cyberattack reports and supported 337 incidents over the year; 80 were nationally significant.
  • For large organisations, 88% of NCSC-handled incidents involved public-facing applications, phishing, misuse of valid accounts or external remote access services.
  • Arctic Wolf’s survey of 1,350 IT and security decision-makers found AI risk was the top concern for 35%, ahead of ransomware at 25%; 14% said AI was central to security operations.
  • The article recommends continuously inventorying internet-facing assets, tracking time to patch critical flaws and replacing end-of-life technology.
  • It advises strengthening identity controls with MFA on remote access, limiting privileges and using phishing-resistant authentication where possible.
  • For AI-enabled threats, it recommends layered defenses, human oversight of AI, incident-response exercises and clear limits on AI agents’ access and actions.
  • The article says the proposed UK Cyber Security and Resilience Bill would update NIS Regulations and introduce incident-reporting requirements; it also notes announced funding for Cyber Essentials and an NCSC agentic security unit.
