With the fast, competitive evolution of new cloud services, particularly those related to security, cloud deployment is now definitively as secure as on-premises servers, and probably even more secure. This practical book surveys current security challenges and shows security professionals, IT architects, and developers how to meet them while deploying systems to popular cloud services. You’ll find up to date, cloud specific security guidance for popular cloud platforms in the areas of cloud and data asset management, identity and access management, vulnerability management, network security, and incident response. Author Chris Dotson offers practical cloud security best practices for multivendor cloud environments whether you’re just starting to design your cloud environment or have legacy projects to secure.
