Cyber Essentials Scheme History 2011-2023

This page brings together the key dates and documents relating to the UK Governments Cyber Essentials Scheme. Where possible links are to the National Archives versions of the historic government websites.

When reviewing historic documents care should be taken to understand how the scheme was organised and run prior to 2020.

The scheme originated in the 2011 UK Cyber Security Strategy which mentioned encouraging the development of a cyber 'kite-mark'. A consultation in 2013 was carried out and concluded that no existing cyber standard would meet their requirements - a new one would therefore need to be created.

Shortly before launch it was reported in multiple outlets that it would be a 3-tier scheme:

# Find-log4j.ps1
#
# Searches a machine for files named log4j-core-*.jar using robocopy and outputs to a file
#
# Virtually all of the code is from Matt Benninge; I've just added a very simple file output 
#   https://gist.github.com/matbe/df32f7257d9eab07fb388bef85edab04
#
# Once you have the files you can combine the ones that found log4j using 
#
#   dir *_found* | Get-Content | Out-File c:\users\public\log4jfound.txt
