Theme-specific policy documents can help the communication and viewing of tasks, instructions and other documentation related to different areas, as well as connecting possible upper-level principles to these contents of the management system, which describe a more detailed implementation.
The organization must define which theme-specific policy documents are maintained and, if necessary, reviewed as a whole at desired intervals. Examples of topics for which you may want to maintain your own policy document include:
- access control
- physical security
- management of assets to be protected
- backup
- encryption practices
- data classification
- technical vulnerability management
- secure development
