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). Security teams must efficiently validate and document exceptions to AWS Security Hub (Cloud Security Posture Management, previously known as Security Hub) findings, while maintaining proper governance. 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 […]
Secure file sharing solutions in AWS: A security and cost analysis guide, Part 1
Securely share sensitive data with time-limited, nonce-enhanced presigned URLs that prevent replay attacks, minimizing exposure risks through granular access controls and rigorous monitoring.
How to migrate your Amazon EC2 Oracle Transparent Data Encryption database encryption keystore to AWS CloudHSM
July 30, 2025: This post has been republished to migrate the Amazon EC2 Oracle Transparent Data Encryption database encryption keystore to AWS CloudHSM using AWS CloudHSM Client SDK 5. Encrypting databases is crucial for protecting sensitive data, helping you to be aligned with security regulations and safeguarding against data loss. Oracle Transparent Data Encryption (TDE) […]
How to automatically disable users in AWS Managed Microsoft AD based on GuardDuty findings
Organizations are facing an increasing number of security threats, especially in the form of compromised user accounts. Manually monitoring and acting on suspicious activities is not only time-consuming but also prone to human error. The lack of automated responses to security incidents can lead to disastrous consequences, such as data breaches and financial loss. In […]
