UK Gov Cookie Cutter Data Science Project Template

This is a data science cookiecutter template for analytical, Python-, or Python and R-based projects within Her Majesty's Government, and wider public sector including policing, where it has been trialled and used as a standardised template for effectively sharing data science work and includes security features using pre-commit hooks to preserve sensitive information.

It also provides an Agile, centralised, and lightweight analytical quality assurance (AQA) process. Pull or merge request templates are used to nudge users to complete this process. This helps meet HM Government best practice on producing quality analysis, as defined in the Aqua Book.

The original developer in GDS has provided a blog post explaining the reasons for creation and provided a live demonstration from March 2021 on version 0.5.3

The National Standards Assurance Board reviewed this in January 2022 and found it being owned and actively developed by the Office for National Statistics, Best Practice and Impact team.

Open Source Software - Exploring the Risk (Good Practice Guide 38)

This guidance seeks to assist a range of IA professionals in exploring the risks associated with the use of Open Source Software (OSS) products. It does so by prompting a number of ‘whole lifecycle’ issues and questions which potential users should ask themselves when making software choices, not just of OSS, but also of proprietary products. This is because there are no ‘right’ or ‘wrong’ answers when it comes to the security of OSS versus that of proprietary (typically closed source code) products. There are good and bad examples of each in this respect and no one type is inherently more, or less, secure than the other.

This guidance supports the Government ICT StrategyI objective of creating a level playing field for open source software solutions. It does not evaluate, recommend or otherwise offer judgement on the following:

Specific OSS products;
Savings in running costs that an organisation may realise by the adoption of OSS over proprietary products;
The legal risks that may arise, for example from issues concerning copyright, intellectual property, or infringement of licences

This guidance was reviewed by the National Standards Assurance Board in January 2021 and was deemed to still provide relevant information

Digital Investigation & Intelligence APP

The digital policing learning programme was created to for officers and staff to update their knowledge regarding digital intelligence and investigation. The programme helps explains the use and misuse of devices and applications and how they appear in the policing world. 

The programme’s aim is to ensure that all staff are:

  • confident facing situations where there is a digital element

  • competent in identifying and carrying out the actions required by those circumstances

  • able to ensure they are compliant in their actions.

The Digital Intelligence and Investigation project will deliver learning and knowledge resources that will ensure that all new and serving officers acquire the digital skills they need to undertake investigations effectively.
