IAM Access Analyzer Update: Extending custom policy checks & guided revocation

We are making IAM Access Analyzer even more powerful, extending custom policy checks and adding easy access to guidance that will help you to fine-tune your IAM policies. Both of these new features build on the Custom Policy Checks and the Unused Access analysis that were launched at re:Invent 2023. Here’s what we are launching: New Custom Policy Checks – Using the power of automated reasoning, the new checks help you to detect policies that grant access to specific, critical AWS resources, or that grant any type of public access. Both of the checks are designed to be used ahead of deployment, possibly as part of your CI/CD pipeline, and will help you proactively detect updates that do not conform…

Amazon Bedrock model evaluation is now generally available

The Amazon Bedrock model evaluation capability that we previewed at AWS re:Invent 2023 is now generally available. This new capability helps you to incorporate Generative AI into your application by giving you the power to select the foundation model that gives you the best results for your particular use case. As my colleague Antje explained in her post (Evaluate, compare, and select the best foundation models for your use case in Amazon Bedrock): Model evaluations are critical at all stages of development. As a developer, you now have evaluation tools available for building generative artificial intelligence (AI) applications. You can start by experimenting with different models in the playground environment. To iterate faster, add automatic evaluations of the models. Then,…
