What is a communication plan?
A communication plan is a document that outlines how information about an organisation's information security management system (ISMS) will be communicated to all interested parties. This includes both internal and external parties, such as employees, customers, suppliers, and regulators.
The communication plan should identify:
- The information that needs to be communicated
- The audience for the information
- The methods of communication
- The frequency of communication
- The responsibilities for communication
An internal communication plan is used to communicate information about the ISMS to employees within the organisation. This information could include the organisation's information security policy, procedures, and risks.
An external communication plan is used to communicate information about the ISMS to parties outside of the organisation, such as customers, suppliers, and regulators. This information could include the organisation's commitment to information security, its security controls, and its incident response procedures.
Why is a communication plan essential?
A communication plan is important for the following reasons:
- It ensures that all interested parties are aware of the organisation's information security risks and controls.
- It helps to build trust and confidence with stakeholders.
- It can help to prevent and mitigate information security incidents.
- It can help to improve the organisation's overall information security posture.
ISO 27001 clause 7.4 is an important requirement for ensuring that all relevant information about the organisation's information security management system is communicated to all interested parties.
By following the guidance in this clause, organisations can effectively communicate their information security risks and controls and can ensure that all personnel are aware of their responsibilities in relation to information security.
