In Q2 2022, the National Cyber Security Centre (NCSC) plans to implement a new assurance scheme for incident response (IR) and simulated exercises (SimEx), which might be a game-changer in the security sector. This will essentially result in the standardization of IR and SimEx across the board, as well as the expansion of commercial reach, opening up new markets for assured suppliers. Previously, the NCSC only offered the Cyber Incident Response (CIR) Service – shortly to be renamed CIR Level 1 – to UK Central Government and major corporations with complex IT systems that were regarded to have "national significance" networks.
The new CIR service will dramatically broaden its reach to include local businesses, major businesses, and SMEs, while the new Cyber Incident Exercising Service will target large and medium organizations, as well as central and regional UK government. Because of the scope of the undertaking, the NCSC aims to hire Assured Scheme Partners to assess and onboard Assured Service Providers to police the scheme.
The government agency is presently selecting its Assured Scheme Partners, with whom it will collaborate to develop the operating model and define how it will execute its technical standards across both services.
SimEx can range from simple desktop exercises to full-fledged simulations, allowing corporate teams to respond to a given attack scenario. They could take the shape of a ransomware or phishing assault, DDoS simulation, or sensitive data being released on the dark web. A simulated exercise's purpose is to practise, analyze, or enhance the IR plan, so the true learning comes from how effectively the incident response process functions.
Although it is unclear how the new Cyber Incident Exercising Service can support this wide range of activities, the NCSC has announced that it will include table-top and live-play formats. It will likely provide a sliding scale of increasingly complicated services, bringing much-needed clarity to the market.
One of the main difficulties with SimEx today is that once the business considers testing its IR, prices may quickly escalate, so a formal framework with multiple techniques would help teams know precisely what they've signed up for and how much bang for their buck they're getting.
Rather than the organization blindly investing in technology and presuming that its policies are being followed, these tests evaluate the effectiveness of security protocols by using attack scenarios that the organization is likely to face in the current threat landscape, informing the business of what is/isn't working and where the disparities are so that future spend can be focused.
