🔴New whitepaper: Designing and deploying a data security strategy with Google Cloud

New 23 page whitepaper from the GCP team: “we wanted to explore both the question of starting a data security program in a cloud-native way, as well as adjusting your existing daily security program when you start utilizing cloud computing.” It covers the 3 pillars of effective cloud security (Identity, Boundary and Access, Visibility), controls that enable the pillars, rethinking your data security strategy, and more.

🔸AWS Accounts as Security Boundaries - 97+Ways Data Can be Shared Across Accounts

Security teams cannot simply rely on the AWS account boundary to limit access between environments. Instead, they must carefully audit IAM policies, resource policies, Organization membership, RAM shares, service-level integrations, and sometimes combinations of one of more of these options, in order to properly evaluate how data from one account is being sent to others.

Although we rely on a one-page diagram as our foundation, an architecture goes deeper than a single block diagram and must be built on a well-structured foundation of fundamentals and security principles. You can use this document in two ways: as a narrative or as a reference.
