How to document your information security policy

Information security policies play a vital role in organisational security. Getting your policy right will give you an excellent framework to build on, making sure that all your efforts follow a single goal. But if you get it wrong, you risk neglecting key issues and exposing yourself to data breaches.

To make sure you get off on the right track, we’ve taken some advice from Alan Calder and Steve Watkins’ IT Governance – An International Guide to Data Security and ISO27001/ISO27002 and Calder’s Nine Steps to Success: An ISO 27001 Implementation Overview

As renowned experts in ISO 27001, the international standard for information security,  their guidance is invaluable for any organisation that’s serious about security. 

Information security policy basics

An information security policy is a set of documents explaining an organisation expects its employees to do in order to prevent security incidents. It doesn’t need to be lengthy, but it must capture senior staff’s ideals and objectives for the organisation. 

The best way to keep the length down is to keep things as simple as possible. You should avoid anything overly prescriptive, as managers need enough freedom to adapt their policies in line with organisational changes. 

The key questions

When putting your information security policy together, there are four questions you must answer: 

  • Who is responsible for the policy? Senior staff must be completely behind the project, and that means they are ultimately accountable. Whoever puts the policy together must communicate with senior staff regularly, and they should have clear evidence (in the form of meeting minutes) showing that the policy was agreed upon. 
  • Where does the policy apply? The policy might apply to the whole organisation or only to certain parts (corporate, divisional, a specific office, etc.). This must be addressed and documented. 
  • What is the policy’s aim? ISO 27001 is specifically about preserving the confidentiality, integrity and availability of information. Your policy should focus on that and only that. 
  • Why is the policy in place? There are many ways information can be compromised, and although you don’t need to go into specifics at this stage, you should have a clear understanding of the threats you are addressing.
