Adopt a Zero Trust Approach with OAuth 2.0 Mutual TLS Client Authentication

In the modern IT stack, API gateways act as the first line of defense against attacks on backend services by enforcing authentication/authorization policies and validating and transforming requests. When backend services are protected with a token-based approach, client applications must obtain an…
Understanding Microsegmentation in Zero Trust Security

With digital transformation shifting networks into the cloud — from remote workforces to online banking — cyberattacks are growing more prevalent and sophisticated. Legacy security models like VPNs and perimeter-based firewalls are proving inadequate in addressing modern threats because perimeters…
Top GraphQL Security Vulnerabilities: Lessons Learned Analyzing 1,500+ Endpoints

With its flexible querying capabilities, GraphQL makes it easy to combine data from multiple sources into a single endpoint. GraphQL and API management go hand in hand to build next-generation API platforms. However, GraphQL's features can also introduce security risks if not properly…
Tightening Bearer Token Authentication with Proof-of-Possession Tokens

In token-based architecture, tokens represent the client’s entitlement to access protected resources. Access tokens (or bearer tokens as they're commonly known) are issued by authorization servers after successful user authentication. The tokens are passed as credentials in the request to the…
Common API Authentication Methods

As businesses expand and gain visibility, it’s natural that their API attack surfaces become more exposed — increasing the risk of dangerous data breaches. Protecting cloud communications and securing data in transit should be your organization’s top priority. API authentication mechanisms help…

OpenID vs OAuth: Understanding API Security Protocols

When it comes to digital identity, OpenID and OAuth are two peas in a pod, but they have their differences. OpenID connects you to relying parties using a single sign-on, while OAuth grants access tokens so you can give apps limited access. They both make authentication simple, seamless, and…
Understand the Differences: API Authentication vs API Authorization

If you landed on this blog post, chances are that you care about keeping your API secure. It's an important topic to discuss: API exploits are on the rise, and you don't want unauthorized users accessing your data. A big part of that security is implementing API authentication and API…
What are API Keys? Overview and Use Cases

Application programming interfaces (APIs) allow software to communicate and share data. But how can those APIs confirm the identity of the clients theyre communicating with? API keys are one solution. API keys are unique codes for authenticating and authorizing access to the features, data, or…
GraphQL Authorization at the API Gateway with Kong Konnect and OPA

In this blog we are going to learn about the technical challenges behind solving GraphQL authorization and how many organizations resolve it today. Then discuss how a Kong / OPA integration can help drive security standards in this space and bring some parity with REST API solutions. Last, we will…
What is OAuth?

OAuth (short for Open Authorization) is a popular, standardized API protocol that provides a secure way for services to quickly share resources for a seamless user experience. Examples of OAuth in action include giving a greeting card service access to your photo library to make a custom holiday…
Dynamic Routing Based on JWT Token’s Claim with Kong Konnect

A common use case that is frequently requested is how to dynamically route requests based on authentication attributes. An example of this technique is routing requests to relevant upstream services based on claims contained in a JWT token. Admins would like all their clients to go to the same URI…
