Amazon Web Services places a high degree of importance on the security of your infrastructure. For an overview of the AWS Security Processes we recommend reviewing their whitepaper.
We also encourage you to review the Securing Data at Rest with Encryption whitepaper for an overview of the methods for securing your data.
If you have questions regarding any aspect of the whitepapers or the security of your environment, please contact a member of your Support team.
As Amazon Web Services says on their Security Bulletins web page, "No matter how carefully engineered the services are, from time to time it may be necessary to notify customers of security and privacy events with AWS services."
If you are interested in staying informed about these security bulletins, the AWS Security Bulletins web page or the companion RSS feed are the appropriate channels to watch. From time to time, Rackspace will provide additional detail or guidance to our customers for specific security incidents. We will publish such value-add security updates below.
