Cryptographic Policy Template
A cryptographic policy template setting out how encryption is used to protect information, including confidential information and personal data, when it is taken off the premises, transferred or accessed remotely.
The policy has Approved By and Date Approved fields and carries a Public information classification, so it can be shared with workers, clients and other interested parties.
What the Cryptographic Policy Covers
- Scope - access to and processing of all information by workers and anyone acting on the organisation's behalf
- Removing information - classified information only removed from the premises in encrypted form
- Portable media and networks - encryption to protect information on portable media and in transit, such as email, websites and backups
- Remote access - encryption on remote access connections to the network
- Algorithms - only recognised strong algorithms, with examples of acceptable symmetric, asymmetric and hash algorithms
- Online transactions - HTTPS with a current version of Transport Layer Security (TLS), and outdated protocols not used
- Key management - keys, certificates and passwords generated, stored, shared and destroyed securely throughout their life
- Enforcement - the consequences of breaching the policy
Checked Against Cyber Essentials
The IT policies in the range have been checked against the Cyber Essentials requirements, so their rules on passwords, devices, access and updates do not contradict what a Cyber Essentials assessment asks for.
Using the Policy
Add your company name and logo, check each commitment matches what your organisation does and edit any that do not, then approve and date the policy and share it with workers and anyone else who needs to see it.
Who Needs a Cryptographic Policy?
Organisations working to ISO 27001, where the use of cryptography is one of the Annex A controls, and organisations that transfer or store confidential or personal information on portable devices or over networks.
Included in the ISO 27001 Toolkit
This policy is part of the ISO 27001 Toolkit and every alphaZ ISO toolkit that covers ISO 27001.
Works with the Information Security Policy Procedure
The same policy is included as the Cryptographic Policy section of the PP-8-100 Information Security Policy Procedure, which is complete without the standalone file. This standalone policy is for organisations that want it as a separate document they can share.
The PP-8-06 Information Transfer Policy Procedure covers transferring information securely.
Document Control
The footer carries the policy number and title, information classification, version and page numbers, and the approval fields record who approved the policy and when, so it can be controlled with the rest of your management system documents and listed on a document register such as the F-IMS20 Document Register.
