Using AWS Secrets Manager Agent with Amazon EKS

AWS Secrets Manager is a service that you can use to manage, retrieve, and rotate database credentials, application credentials, API keys, and other secrets throughout their lifecycles. You can also use Secrets Manager to replace hard-coded credentials in application source code with runtime calls to retrieve credentials dynamically when needed. Managing secrets in Amazon Elastic […]

Securing Amazon Bedrock API keys: Best practices for implementation and management

Recently, AWS released Amazon Bedrock API keys to make calls to the Amazon Bedrock API. In this post, we provide practical security guidance on effectively implementing, monitoring, and managing this new option for accessing Amazon Bedrock to help you build a comprehensive strategy for securing these keys. We also provide guidance on the larger family […]

Protect your generative AI applications against encoding-based attacks with Amazon Bedrock Guardrails

Amazon Bedrock Guardrails provides configurable safeguards to help you safely build generative AI applications at scale. It offers integrated safety and privacy protections that work across multiple foundation models (FMs), including models available in Amazon Bedrock and models hosted outside Amazon Bedrock from other providers. Bedrock Guardrails currently offers six key safeguards to help prevent […]

Build secure network architectures for generative AI applications using AWS services

As generative AI becomes foundational across industries—powering everything from conversational agents to real-time media synthesis—it simultaneously creates new opportunities for bad actors to exploit. The complex architectures behind generative AI applications expose a large surface area including public-facing APIs, inference services, custom web applications, and integrations with cloud infrastructure. These systems are not immune to […]

How to accelerate security finding reviews using automated business context validation in AWS Security Hub CSPM

October 1, 2025: This post was updated to reflect the new name of Security Hub, which is AWS Security Hub CSPM (Cloud Security Posture Management).

Enterprise security teams need […]

Authorizing access to data with RAG implementations

Organizations are increasingly using large language models (LLMs) to provide new types of customer interactions through generative AI-powered chatbots, virtual assistants, and intelligent search capabilities. To enhance these interactions, organizations are using Retrieval-Augmented Generation (RAG) to incorporate proprietary data, industry-specific knowledge, and internal documentation to provide more accurate, contextual responses. With RAG, LLMs use an […]

Enhance TLS inspection with SNI session holding in AWS Network Firewall

AWS Network Firewall is a managed firewall service that filters and controls network traffic in Amazon Virtual Private Cloud (Amazon VPC). Unlike traditional network controls such as security groups or network access control lists (NACLs), Network Firewall can inspect and make decisions based on information from higher layers of the OSI model, including the Transport […]

Automate OIDC client secret rotation with Application Load Balancer

Elastic Load Balancing simplifies authentication by offloading it to OpenID Connect (OIDC) compatible identity providers (IdPs). This lets builders focus on application logic while using robust identity management. OIDC client secrets are confidential credentials used in OAuth 2.0 and OIDC protocols for authenticating clients (applications). However, manual management of OIDC client secrets introduces security risks […]

Amazon EC2 defenses against L1TF Reloaded

The guest data of AWS customers running on the AWS Nitro System and Nitro Hypervisor is not at risk from a new attack dubbed “L1TF Reloaded.” No additional action is required by AWS customers; however, AWS continues to recommend that customers isolate their workloads using instance, enclave, or function boundaries as described in AWS public […]

Secure file sharing solutions in AWS: A security and cost analysis guide: Part 2

As introduced in Part 1 of this series, implementing secure file sharing solutions in AWS requires a comprehensive understanding of your organization’s needs and constraints. Before selecting a specific solution, organizations must evaluate five fundamental areas: access patterns and scale, technical requirements, security and compliance, operational requirements, and business constraints. These areas cover everything from […]
