Configuration and Vulnerability Analysis in Amazon Redshift

AWS handles basic security tasks like guest operating system (OS) and database patching, firewall configuration, and disaster recovery (DR). These procedures have been reviewed by certified third parties. For more information, see Compliance Validation for Amazon Redshift, the Shared Responsibility Model, and the Amazon Web Services: Overview of Security Processes whitepaper.

Amazon Redshift automatically applies upgrades and patches your data warehouse so you can focus on your application and not on its administration. Patches and upgrades are applied during a configurable maintenance window. For more information, see Maintenance Windows.
