The UK's National Cyber Security Centre (NCSC) announced a new Cyber Adversary Simulation (CyAS) scheme on 2026-11-11 (ncsc.gov.uk), aimed at helping critical organisations strengthen their cyber resilience. Trusted providers will carry out rigorous, real-world testing to identify and fix vulnerabilities (ncsc.gov.uk). Infosecurity Magazine's coverage on 2026-11-12 adds that the scheme targets critical infrastructure providers and is initially running as a Minimum Viable Product (MVP) so the approach can be refined and confidence built before full deployment (infosecurity-magazine.com). The NCSC ties the announcement to an upcoming wave of security patches meant to address long-standing technical debt, and stresses proactive vulnerability management (ncsc.gov.uk). It is also researching how to tell 'forgivable' vulnerabilities from 'unforgivable' ones, to support top-level mitigation and prevent organisations losing memory of past vulnerabilities (ncsc.gov.uk). The sources describe no specific threat actor, CVE or active exploitation.
Detalhes técnicos
- Participating organisations select vetted suppliers to simulate realistic cyberattacks tailored to their own IT environments and threat landscapes (infosecurity-magazine.com).
- The approach takes an adversarial mindset that goes beyond typical threat intelligence or fixed TTPs (infosecurity-magazine.com).
- CyAS complements existing NCSC frameworks, the Cyber Assessment Framework (CAF) and the Cyber Resilience Audit (CRA). It aims to provide more rigorous assessments that better reveal security weaknesses and support continual improvement (infosecurity-magazine.com).
Remediação
- Critical organisations should consider taking part in CyAS and choosing a vetted supplier for adversary simulation, as the scheme is currently an MVP (infosecurity-magazine.com).
- Prepare for the upcoming wave of security patches and use it to reduce long-standing technical debt (ncsc.gov.uk).
- Keep records of past vulnerabilities so that organisational memory is not lost (ncsc.gov.uk).

The UK National Cyber Security Centre (NCSC) has introduced the Cyber Adversary Simulation (CyAS) scheme to help critical infrastructure providers test and improve their cyber resilience. Participating organizations select vetted suppliers to simulate realistic cyberattacks tailored to their specific IT environments and threat landscapes, adopting an adversarial mindset beyond typical threat intelligence or fixed TTPs. CyAS complements existing NCSC frameworks like the Cyber Assessment Framework (CAF) and Cyber Resilience Audit (CRA), aiming to provide rigorous assessments that better reveal security weaknesses and support continual improvement. Initially operating as a Minimum Viable Product (MVP), the program seeks to refine its approach and build confidence before full deployment, ultimately enhancing the UK's ability to protect essential services from cyber threats.

The UK's National Cyber Security Centre (NCSC) has announced a new Cyber Adversary Simulation scheme aimed at helping critical organisations strengthen their cybersecurity resilience. This initiative will involve trusted providers conducting rigorous, real-world testing to identify and rectify vulnerabilities. The timing coincides with an upcoming wave of security patches to address long-standing technical debt, emphasizing the importance of proactive vulnerability management. Additionally, the NCSC is researching methods to distinguish 'forgivable' vulnerabilities from 'unforgivable' ones, facilitating top-level mitigation strategies and preventing the loss of organizational memory regarding past vulnerabilities. This comprehensive approach aims to enhance the preparedness and response capabilities of essential sectors.
