There is no specific document for information security in project management because you can use the same documents you use for an ISMS applied to your organization (there is no need for documents specific for managing information security in a project).

For example, in case your project needs to adopt a backup policy, you can use the same Backup Policy document adopted by your organization.

What happens sometimes is that for project management, you may have specific requirements, but you can implement those by adding specific sections in the related documents (e.g., a section called “backup for projects” in the Backup Policy).
