AWS Security Blog

Read all about the latest AWS security features, compliance updates, and hands-on resources in our new, monthly digest posts. You’ll find expert blog posts, new service capabilities, code samples, and workshops. AWS Security Blog posts This month’s AWS Security Blog posts covered identity and access management, threat intelligence, network security, AI-powered security tooling, and multi-account […]

Security Hub is our foundation for full-stack enterprise security across clouds. It centralizes your security operations and turns raw signals into prioritized insights, so your team spends its time managing real risk instead of stitching tools together. Today that foundation grows in two directions our customers asked for most. We are adding purpose-built protection for […]

As AI agents and automated tools increasingly access web applications, distinguishing legitimate bot traffic from malicious attempts has become a critical security challenge. Traditional approaches such as IP-based filtering and reverse DNS lookups fail in multi-tenant systems (such as Amazon Bedrock AgentCore) where thousands of distinct workloads share the same IP space. Attackers can easily […]

We are pleased to announce the publication of a new AWS compliance implementation guidance: HITRUST i1 Compliance on AWS: Customer Implementation Guidance with an Illustrative Healthcare Platform. Healthcare organizations seeking HITRUST i1 certification increasingly rely on Amazon Web Services (AWS) as their cloud foundation. The HITRUST i1 assessment covers 182 curated controls at the Implemented […]

Amazon Web Services EMEA Sarl (AWS) has been designated as a critical third party (CTP) to the UK financial sector by HM Treasury. The CTP regime came into force on January 1, 2025, and establishes a framework through which the Bank of England, PRA, and FCA (collectively the UK regulators) can set requirements on and […]

You can now connect your agents to the AWS MCP Server using the same credentials and sign-in methods that you already use for connecting to the AWS Management Console or AWS Command Line Interface (AWS CLI) through a familiar browser-based experience powered by industry-standard OAuth. This new sign-in path supports AWS Identity and Access Management […]

System prompts form the foundation of generative AI applications. A system prompt is a collection of instructions and operational context provided to a large language model (LLM) that shapes how the model behaves and interacts with users and tools. System prompts often contain proprietary information, including role definitions, behavioral guidelines, tool descriptions and usage instructions, […]

Over a dozen major economies have now published post-quantum cryptography (PQC) adoption guidance. As a CISO, you’re probably well into your migration plan and know the most difficult part has little to do with changing algorithms. The real leadership challenge is driving coordinated change across a large, complex organization where asymmetric cryptography is embedded in […]

With the introduction of models that require data sharing with third-party providers—such as Claude Fable 5—organizations need a way to centrally enforce data retention policies. Amazon Bedrock gives you control over whether your prompts and model outputs are retained after an inference request completes. You might need a way to enforce your retention settings across […]

If you’re building multi-agent AI systems, you need to prevent authorization scope from silently expanding as agents delegate tasks through multi-hop chains. Without proper controls, an agent can potentially act beyond what the originating user authorized, even when role-based access control (RBAC) policies are in place. The OWASP Top 10 for Agentic Applications classifies this […]
