Version control systems are designed to manage changes to documents, computer programs, large websites, and other collections of information. By implementing a version control system, the administrator can track changes made to the security policy documents, establish who made each change, and revert to earlier versions of the documents if required. This provides an audit trail, fosters accountability, and ensures the integrity of documents over time. While permissions and backing up files are essential, these do not inherently provide the ability to manage and track changes to the documents as they evolve or maintain a history of revisions.
