PEP and PDP for Secure Authorization with AVP and ABAC

2025-05-06

aws, authz, serverless

Taking our authorization system to the next level! In this third part of our series, we're enhancing our Amazon Verified Permissions (AVP) solution with Attribute-Based Access Control (ABAC). By combining RBAC and ABAC, we get a powerful authorization system that can enforce fine-grained access based on user attributes and context - perfect for multi-tenant applications where access control needs to account for more than just roles.

2025-04-10

Serverless EventDriven AWS Devops

This talk will explore how a fintech market leader in Sweden, created a serverless and event-driven integration with Slack on AWS. Creating a solution, to automate tasks across a multi-account setup. Learn how this journey optimized cost, enhanced productivity and security by eliminating repetitive tasks, by minimizing human error. A key aspect was integrating alarms and notifications directly into Slack, enabling developers to take immediate action on system alerts. We will look at the problems, deep dive into implementation, and the challenges we faced. Join us to gain valuable insights and practical tips for transforming your workflows.

Event-Driven and serverless in world of IoT

2025-04-02

Serverless IoT AWS

In large-scale IoT systems, where thousands of devices are constantly communicating, data and control messages can flow unpredictably and at varying rates throughout the day. Serverless and event-driven architectures provide a dynamic and efficient solution to this challenge. In this session, we’ll explore why serverless is a great fit for IoT, particularly in handling data ingestion and management. We’ll dive into the key architectural patterns used in IoT systems, highlighting how event-driven design enables scalability, flexibility, and cost optimization. I’ll also walk you through an architecture I designed for an IoT use case, showcasing the integration of various AWS services tailored for data ingestion, processing, and analytics. Along the way, we’ll discuss the challenges encountered and lessons learned during development, offering actionable insights into the unique aspects of building serverless IoT solutions. Join me to understand how serverless and event-driven architectures can unlock the full potential of IoT, enabling resilient and scalable systems that are easy to manage and adapt to evolving demands.

PEP and PDP for Secure Authorization with AVP

2025-02-20

aws, authz, serverless

As authorization needs evolve, managing access efficiently becomes even more crucial. In this follow-up post, we extend our Policy Decision Point (PDP) and Policy Enforcement Point (PEP) solution by introducing Amazon Verified Permissions (AVP) for fine-grained authorization. Instead of storing permissions in DynamoDB, we leverage AVP’s centralized policy engine and Cedar policy language to define and enforce access control dynamically.

PEP and PDP for Secure Authorization with Cognito

2025-01-30

aws, authz, serverless

Authorization is a critical part of securing cloud applications, and understanding the best practices for implementing it can make all the difference. In this post, we dig deep on the concepts of Policy Decision Points (PDPs) and Policy Enforcement Points (PEPs), and how they work together to manage user access efficiently. We dive into a serverless solution using AWS Lambda and API Gateway, implementing Role-Based Access Control (RBAC) for fine-grained access control based on Cognito User Groups. This solution ensures scalability, low latency, and efficient authorization in serverless environments.

Serverless self-service IoT certificate management - Part 2.

2024-12-22

aws, iot, security, serverless

Secure communication is a important in IoT systems, where certificates and trust play a vital role. In this post we extend the API introduced in part 1, we will add functionality to create device certificates, introduce an inventory, add some event-driven parts, and the possibility to list and get certificates. This hands-on approach is great for learning purposes and development environments, production setups however require robust managed solutions.

Serverless AI powered content moderation service

2024-10-31

aws, ai, security, serverless

In this post, I extend the File Manager service I built previously by adding content moderation capabilities. The original service stores files in S3 and records them in a DynamoDB table, using a serverless, event-driven approach. Now, with AWS GuardDuty and Rekognition, I’ve enhanced the service with malware scanning and image moderation.

Building a serverless connected BBQ as SaaS - Part 4 - AuthZ
