You should use encrypted communications channels when transmitting any personal data over an untrusted network.
Storing encrypted data still poses residual risks.Some applications and databases can be configured to store data in encrypted form.You can also encrypt individual files or create encrypted containers.Most modern operating systems have full-disk encryption built-in.Encrypting data whilst it is being stored provides effective protection against unauthorised or unlawful processing.You should also be aware of any sector-specific guidance that applies to you, as this may require you to use encryption.
You should have a policy in place governing the use of encryption, including appropriate staff education.You should consider encryption alongside other technical and organisational measures, taking into account the benefits it can offer and the risks it can pose.Encryption protects information stored on mobile and static devices and in transmission, and there are a number of different encryption options available.
It is a way of safeguarding against unauthorised or unlawful processing of personal data, and is one way in which you can demonstrate compliance with the security principle.Encryption is a mathematical function that encodes data in such a way that only authorised users can access it.It is possible that, where data is lost or destroyed and it was not encrypted, regulatory action may be pursued (depending on the context of each incident).It is also the case that encryption solutions are widely available and can be deployed at relatively low cost.In many cases, the damage and distress caused by these incidents may have been reduced or even avoided had the personal data been encrypted. The ICO has seen numerous incidents of personal data being subject to unauthorised or unlawful processing, loss, damage or destruction. This includes specifying encryption as an example of an appropriate technical measure, depending on the risks involved and the specific circumstances of your processing. Article 32 provides further considerations for the security of your processing.The UK GDPR’s security principle requires to you put in place appropriate technical and organisational measures to ensure you process personal data securely.What does the UK GDPR say about encryption? What does the UK GDPR say about encryption?.☐ We have considered the types of processing we undertake, and whether encryption can be used in this processing. ☐ We ensure that we keep our encryption solution(s) under review in the light of technological developments. ☐ Our encryption solution(s) meet current standards such as FIPS 140-2 and FIPS 197. ☐ We understand the residual risks that remain, even after we have implemented our encryption solution(s). ☐ We have assessed the nature and scope of our processing activities and have implemented encryption solution(s) to protect the personal data we store and/or transmit. ☐ We ensure that we educate our staff on the use and importance of encryption. ☐ We have an appropriate policy in place governing our use of encryption. ☐ We understand that encryption can be an appropriate technical measure to ensure that we process personal data securely.
