Clause 7.5.2 states that an organization must establish, implement, and maintain documented information security policies that are consistent with the information security objectives and support the organization's overall business objectives. These policies should provide a framework for the management of information security and should be reviewed regularly to ensure their continuing suitability, adequacy, and effectiveness.
The specific requirements outlined in this clause include:
- Establishing information security policies: The organization must develop and define its information security policies. These policies should clearly articulate the organization's commitment to information security, its approach to managing risks, and the expectations for employees and other relevant parties regarding information security.
- Implementing information security policies: Once the policies are established, they need to be effectively implemented throughout the organization. This involves communicating the policies to all relevant parties, providing training and awareness programs to ensure understanding and compliance, and integrating the policies into the organization's business processes.
- Maintaining information security policies: The organization must ensure that its information security policies are regularly reviewed and kept up to date. This involves conducting periodic reviews to assess the policies' continuing suitability, adequacy, and effectiveness in addressing the organization's information security requirements. Any necessary updates or modifications should be made based on the review results.
