ISO 27001 Identification of legal, statutory, regulatory and contractual requirements is about making sure an organisation follows all the rules and agreements that apply to its information. Think of it as a checklist to ensure you’re not breaking any laws or promises when handling data.

Examples

  • Privacy Laws: A company must follow laws like the General Data Protection Regulation (GDPR) when it handles people’s personal information. This means it has to protect the data and get permission to use it.
  • Industry Rules: A bank has to follow rules set by the financial industry that say how it must protect customer money and information.
  • Contracts: A business has a written agreement with a client to keep their project details secret. This business must have a way to make sure only the right people can see those details.

Context

Following this control helps a company avoid trouble. If a company doesn’t follow the rules, it could get finedsued, or lose business. For example, a hospital must keep patient records private by law. If it doesn’t, it could face a big penalty. This control helps businesses stay in business by showing they can be trusted with important information.
