GuardDuty Extended Threat Detection has added five new indicators to surface attack sequences
Amazon GuardDuty Extended Threat Detection correlates weak GuardDuty signals into a single, critical-severity attack sequence finding when their composition crosses a threshold of credibility. On May 20, 2026, the service started attaching five new indicator types to those sequences: MALICIOUS_PACKAGE, MISCONFIGURATION, REACHABILITY, SENSITIVE_DATA, and VULNERABILITY. For more information, see Document history for Amazon GuardDuty and […]
Quantum-resistant signing on AWS, Part 2: Enforce your ML-DSA algorithm policy with SCPs and IAM
You want to set a cryptographic algorithm policy and stop non-compliant choices from being made in your Amazon Web Services (AWS) environment. This post shows you how. As you adopt post-quantum cryptography, one of the first decisions you face is which algorithms and parameter sets fit your business needs, balancing security against signature size, key […]
Quantum-resistant signing on AWS, Part 1: Build a software supply chain with ML-DSA
Software supply chain attacks have grown in both frequency and sophistication. Recent high-profile compromises of build systems and open source dependencies demonstrate that attackers increasingly target the trust mechanisms that verify software integrity. Those trust mechanisms rely on digital signature algorithms, and today many use traditional algorithms such as Rivest-Shamir-Adleman (RSA) and the Elliptic Curve […]
Improving SPIRE security and resiliency with AWS managed services
In cloud-centered environments, establishing trust between workloads is fundamental to securing machine-to-machine communication. Traditional approaches such as API keys, shared secrets, and static service account credentials weren’t designed for the scale and ephemeral nature of cloud workloads. This drives an organizational need to shift from long-term, static credentials to short-lived cryptographic workload identities. Organizations are […]
Identity-aware AI data agents with AWS Lake Formation and Trusted Identity Propagation
You’re building a data agent that lets business users ask questions about lakehouse data in natural language. You’ve already built governance policies that control who can access which datasets. The challenge is making the agent respect those rules without rebuilding them in your application code. When a user asks a question, the agent maps it […]
Architecting a secure landing zone in the AWS European Sovereign Cloud
The AWS European Sovereign Cloud is a new, independent cloud for Europe, physically and logically separate from existing AWS Regions and operated within the European Union (EU). It provides the same services, features, and APIs as AWS commercial Regions, but runs as a distinct AWS partition (aws-eusc), with its own control plane, AWS Identity and […]
AWS STS simplifies session token size limits and adds session token size monitoring
AWS Security Token Service (AWS STS) has simplified session token size limits, giving you more room for your session policies and session tags. STS has replaced the packed policy size and the overall session token size limits with a single token size limit of 4,096 bytes. STS now reports session token size in API responses, […]
Architecting resilient authentication with Amazon Cognito multi-Region replication
Your consumer identity and access management (CIAM) system is the foundation of your customer experience. It’s how users sign in, access services, and engage with your applications. As your business scales across geographies, ensuring authentication is always available becomes a core architectural requirement. However, building multi-Region authentication has traditionally required complex custom replication solutions that […]
Operationalizing least privilege: Automate IAM remediation through your CI/CD pipeline
The principle of least privilege is straightforward to articulate but challenging to maintain at scale. When teams first deploy applications to AWS, they often grant broader permissions than strictly necessary; it’s faster to get things working, and the plan is always to tighten permissions later. But later rarely comes. Permissions accumulate, AWS Identity and Access […]
Managing identity source transition for AWS IAM Identity Center
September 2, 2026: This post was republished to include Active Directory migration strategies and automation for permission sets. AWS IAM Identity Center manages user access to Amazon Web Services (AWS) resources, including both AWS accounts and applications. You can use IAM Identity Center to create and manage user identities within the Identity Center identity store […]
