Information Security Policy
Section titled “Information Security Policy”An information security policy states why the organization protects information and what leadership commits to doing. It should explain whose information is protected and leadership’s responsibilities, rather than list detailed configuration values.
Here, “security policy” means the top-level policy. Since other organizations use the term for the entire documentation system, explain the document’s position at the start.

Section titled “Public and internal versions”A public version can focus on purpose, commitments, and general practices. Assess disclosure before including monitoring details, system architecture, personal contact information, or specific weaknesses; place sensitive details in controlled internal documents.
If an internal version explains scope and authority more fully, keep its commitments consistent with the public version. Avoid unverifiable promises such as preventing every incident or guaranteeing complete safety.
