Centrally manage VPC network ACL rules to block unwanted traffic using AWS Firewall Manager
Amazon Virtual Private Cloud (Amazon VPC) provides two options for controlling network traffic: network access control lists (ACLs) and security groups. A network ACL defines inbound and outbound rules that allow or deny traffic based on protocol, IP address range, and port range. Security groups determine which inbound and outbound traffic is allowed on a […]
Access AWS services programmatically using trusted identity propagation
With the introduction of trusted identity propagation, applications can now propagate a user’s workforce identity from their identity provider (IdP) to applications running in Amazon Web Services (AWS) and to storage services backing those applications, such as Amazon Simple Storage Service (Amazon S3) or AWS Glue. Since access to applications and data can now be […]
SaaS tenant isolation with ABAC using AWS STS support for tags in JWT
As independent software vendors (ISVs) shift to a multi-tenant software-as-a-service (SaaS) model, they commonly adopt a shared infrastructure model to achieve cost and operational efficiency.

Establishing a data perimeter on AWS: Analyze your account activity to evaluate impact and refine controls
A data perimeter on Amazon Web Services (AWS) is a set of preventive controls you can use to help establish a boundary around your data in AWS Organizations. This boundary helps ensure that your data can be accessed only by trusted identities from within networks you expect and that the data cannot be transferred outside […]

How to set up SAML federation in Amazon Cognito using IdP-initiated single sign-on, request signing, and encrypted assertions
When an identity provider (IdP) serves multiple service providers (SPs), IdP-initiated single sign-on provides a consistent sign-in experience that allows users to start the authentication process from one centralized portal or dashboard. It helps administrators have more control over the authentication process and simplifies the management. However, when you support IdP-initiated authentication, the SP (Amazon […]
Governing and securing AWS PrivateLink service access at scale in multi-account environments
Amazon Web Services (AWS) customers have been adopting the approach of using AWS PrivateLink to have secure communication to AWS services, their own internal services, and third-party services in the AWS Cloud.
