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 […]
Transforming Bedrock Guardrails events into OCSF with CloudWatch
Security teams investigating possible AI-related security events need guardrail intervention data alongside their existing security telemetry. When a guardrail identifies or blocks a prompt injection attempt or redacts sensitive data, that intervention carries additional investigative value comparable to a failed sign-in or a network intrusion alert. AWS Bedrock publishes this telemetry to AWS CloudWatch metrics […]
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 […]
The state of AI for security: Measuring what matters most for building trust
Security teams are starting to actively use AI for security work, including vulnerability triage, penetration testing, threat modeling, incident response, and code review. The promise is speed, but a security tool that moves fast and raises too many false alarms doesn’t save time. Engineers spend time on false alarms, on-call is noisier, and teams distrust […]
Incident response guide for AWS CloudTrail investigations – Part 2
In Part 1 of this guide, we examined two common incident scenarios: cross-account Amazon Simple Storage Service (Amazon S3) data deletion with ransomware implications, and cryptocurrency mining deployed through AWS CloudFormation using exposed AWS Management Console credentials. We also introduced key incident response terminology and investigative frameworks for analyzing AWS CloudTrail events. In this second […]
Incident response guide for AWS CloudTrail investigations – Part 1
AWS CloudTrail logs contain the evidence you need when investigating suspicious activity in your AWS environment, but knowing which fields matter and how to interpret them can mean the difference between surface-level analysis and uncovering the full scope of an incident. This guide walks you through real-world scenarios, showing you how to analyze CloudTrail events […]
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 […]
