New IAMCTL tool compares multiple IAM roles and policies
If you have multiple Amazon Web Services (AWS) accounts, and you have AWS Identity and Access Management (IAM) roles among those multiple accounts that are supposed to be similar, those roles can deviate over time from your intended baseline due to manual actions performed directly out-of-band called drift.

Enhance programmatic access for IAM users using a YubiKey for multi-factor authentication
Organizations are increasingly providing access to corporate resources from employee laptops and are required to apply the correct permissions to these computing devices to make sure that secrets and sensitive data are adequately protected. The combination of Amazon Web Services (AWS) long-term credentials and a YubiKey security token for multi-factor authentication (MFA) is an option […]
Securing resource tags used for authorization using a service control policy in AWS Organizations
In this post, I explain how you can use attribute-based access controls (ABAC) in Amazon Web Services (AWS) to help provision simple, maintainable access controls to different projects, teams, and workloads as your organization grows. ABAC gives you access to granular permissions and employee-attribute based authorization. By using ABAC, you need fewer AWS Identity and […]

IAM Access Analyzer flags unintended access to S3 buckets shared through access points
Customers use Amazon Simple Storage Service (S3) buckets to store critical data and manage access to data at scale. With Amazon S3 Access Points, customers can easily manage shared data sets by creating separate access points for individual applications. Access points are unique hostnames attached to a bucket and customers can set distinct permissions using […]
Rely on employee attributes from your corporate directory to create fine-grained permissions in AWS
In my earlier post Simplify granting access to your AWS resources by using tags on AWS IAM users and roles, I explained how to implement attribute-based access control (ABAC) in AWS to simplify permissions management at scale. In that scenario, I talked about relying on attributes on your IAM users and roles for access control […]
