Your workloads reach most destinations by domain name, but a firewall can only act on what it sees in the traffic. For HTTP and HTTPS, AWS Network Firewall domain rules match the name that the client puts in the request, and the client chooses that name. The connections for protocols such as SSH and SSH […]

October 23, 2026-2: The PHP project disclosed CVE-2026-115560, a separate remote code execution issue that the October 21 releases don’t fix. It affects only applications with an uncommon configuration that keeps session upload progress enabled. The PHP2Shell_BODY rule in the PHP application managed rule group, version 2.4 and later, already blocks POST requests that carry […]

October 20, 2026: This post was republished to reflect the new migration capability from Active Directory to an external identity provider (IdP) or the Identity Center directory, now available in 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 […]

Most security tooling that fits into a CI/CD pipeline—static analysis (SAST), software composition analysis (SCA), and dynamic scanners (DAST)—flags potential issues from patterns and signatures. A flagged pattern shows you where to look; penetration testing is what confirms whether something is actually exploitable. That confirmation has traditionally come from a periodic, out-of-band engagement that runs […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
