One of CESG’s roles is to minimise the risk of electronic attack to the Government community. This involves assessing the technical capabilities of an attacker, identifying vulnerabilities associated with technologies utilised within Government systems, and to provide advice and guidance to the community on securing IT systems.

CESG through its CERT function (GovCertUK) will regularly release technical papers to the Government community. These technical papers will offer practical advice on network security issues and will be aimed at the information security teams within the Government community.
