What the GFSC Cyber Security Rules and Guidance 2021 mean for your business.

Cyber Security
27 April 2022

The Guidance issued states that all Guernsey licensed institutions are required to have robust policies, procedures and controls in place to identify, assess and manage cyber security risks on an ongoing basis consistent with the minimum licensing requirements.

The five core principles (Identify, Protect, Detect, Respond & Recover) that the GFSC outlines are most often associated with the NIST* framework but ISO 27001 and the IASME Governance Standard** are broadly equivalent.

Many companies in Guernsey and Jersey now have Cyber Essential accreditation, which assures compliance with many of the technical elements required by the GFSC, but as they correctly state, this certification will not result in full compliance.

The goals of NIST, ISO 27001 and IASME Governance are the same, with the emphasis on identifying, evaluating and managing the acceptable risks to information systems. All three frameworks require an Information Security Management System (ISMS).

The GFSC state that “accreditation alone is unlikely to result in full compliance” and from a technical perspective they are correct. Robust Cyber Security requires an ISMS built on three pillars: people, processes and technology. An ISMS developed in accordance with the IASME Governance Standard and which also incorporates technical controls can and will demonstrate compliance to the Cyber Security Rules published by the GFSC.

The new requirements are extensive and far-reaching and it would be no exaggeration to say that many, or most, licensed institutions do not comply with the new Cyber Security rules.

** The IASME Governance standard was developed over several years during a UK Government funded project to create a cyber-security standard which would be an affordable and achievable alternative to the international standard, ISO 27001.
