Description#
AWS Redshift is a fully managed, data warehousing solution from Amazon Web Services. It is capable of processing structured and unstructured data in the range of thousands of petabytes.
The database should always be encrypted at rest to protect the data if accesses are compromised.
Impact#
Not encrypting data at rest could lead to data leak in case of an attack.
Remediation guidelines#
Enable encryption for Redshift clusters, providing a customer managed key (CMK). See https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#key-mgmt for more details on CMK.
