Use Amazon Verified Permissions for fine-grained authorization at scale
Implementing user authentication and authorization for custom applications requires significant effort. For authentication, customers often use an external identity provider (IdP) such as Amazon Cognito. Yet, authorization logic is typically implemented in code. This code can be prone to errors, especially as permissions models become complex, and presents significant challenges when auditing permissions and deciding […]
Migrate your Windows PKI from Microsoft Active Directory Certificate Services to AWS Private CA Connector for Active Directory
When you migrate your Windows environment to Amazon Web Services (AWS), you might need to address certificate management for computers and users in your Active Directory domain. Today, Windows administrators commonly use Active Directory Certificate Services (AD CS) to support this task. In this post, we will show you how to migrate AD CS to […]
Securing generative AI: Applying relevant security controls
This is part 3 of a series of posts on securing generative AI. We recommend starting with the overview post Securing generative AI: An introduction to the Generative AI Security Scoping Matrix, which introduces the scoping matrix detailed in this post. This post discusses the considerations when implementing security controls to protect a generative AI […]
SaaS access control using Amazon Verified Permissions with a per-tenant policy store
Access control is essential for multi-tenant software as a service (SaaS) applications. SaaS developers must manage permissions, fine-grained authorization, and isolation. In this post, we demonstrate how you can use Amazon Verified Permissions for access control in a multi-tenant document management SaaS application using a per-tenant policy store approach.

How to migrate asymmetric keys from CloudHSM to AWS KMS
In June 2023, Amazon Web Services (AWS) introduced a new capability to AWS Key Management Service (AWS KMS): you can now import asymmetric key materials such as RSA or elliptic-curve cryptography (ECC) private keys for your signing workflow into AWS KMS. This means that you can move your asymmetric keys that are managed outside of […]
Data masking and granular access control using Amazon Macie and AWS Lake Formation
Companies have been collecting user data to offer new products, recommend options more relevant to the user’s profile, or, in the case of financial institutions, to be able to facilitate access to higher credit lines or lower interest rates. However, personal data is sensitive as its use enables identification of the person using a specific […]
How to build a unified authorization layer for identity providers with Amazon Verified Permissions
Enterprises often have an identity provider (IdP) for their employees and another for their customers. Using multiple IdPs allows you to apply different access controls and policies for employees and for customers. However, managing multiple identity systems can be complex. A unified authorization layer can ease administration by centralizing access policies for APIs regardless of […]
How to use AWS Database Encryption SDK for client-side encryption and perform searches on encrypted attributes in DynamoDB tables
Today’s applications collect a lot of data from customers. The data often includes personally identifiable information (PII), that must be protected in compliance with data privacy laws such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). Modern business applications require fast and reliable access to customer data, and Amazon […]
OT/IT convergence security maturity model
For decades, we’ve watched energy companies attempt to bring off-the-shelf information technology (IT) systems into operations technology (OT) environments. These attempts have had varying degrees of success. While converging OT and IT brings new efficiencies, it also brings new risks. There are many moving parts to convergence, and there are several questions that you must […]
