Why ISO 27001 Information Classification Is Important

Information classification is a crucial aspect of any ISO 27001 project. A proper classification allows you to determine how information should be handled and what controls need to be in place for its protection. Failing to classify your information puts its value and security at risk. So, where should you begin with information classification? The first step is to develop an information classification policy. This policy will establish different levels of classification, define which information falls into each category, and determine the corresponding controls. Rather than creating a policy from scratch, it is advisable to use a template designed by ISO 27001 experts. Once you have a classification policy in place, applying information classifications practically becomes essential. Some individuals choose to add classifications to the footer of their documents. For instance, if a Word document contains information classified as 'confidential,' they would include the word 'confidential' in the footer. However, this method is not foolproof, as there is a risk of forgetting to classify important documents. Other options, like using stamps, have proven impractical for certain types of information.
