Considering the following facts, using CSRF token for a restful API (which of course is intrisincly session-less) seems inevitable:
storing JWT in local storage(any where other than http-only cookie) makes the API vulnerable to XSS attack… Continue reading How to implement the CSRF token mechanism for restful APIs?
I am working on security analysis of jwt python libraries. I want to analyze how the libraries work and how they were used in development. Not the source code. Also I have to check the jwt libraries against known attacks like:
None algori… Continue reading How to perform security analysis of jwt authentication libraries
I’d like to rewrite a monolithic social website to use JWT for authentication instead of traditional cookie/sessionm, and I’m looking for a secure implementation. I read here that:
You might think an HttpOnly cookie (created by the server… Continue reading What is considered a secure way to store JWT in browser?
Are there any security risks to returning a user’s JWT in the response body to a GET request? The JWT is only returned for authenticated users. Authentication is managed via a JWT stored as a HttpOnly, Secure, SameSite:Lax cookie.
Flow, in… Continue reading Security risks to returning JWT token in the response body to a GET request?
In Kubernetes, I use an nginx ingress controller to do TLS termination and load balancing.
When mutual TLS is used, the ingress controller can be configured to forward the client certificate as an http field, but this information is obviou… Continue reading How to trust the Kubernetes ingress controller?
My question is : Is this approach correct given I have a non-Oauth service? My goal is to use the simplest amount of security features while still being as strong as possible.
My approach is as follows and I am asking for feedback on wheth… Continue reading I have a non-Oauth service and am using this approach with Server initiated HttpOnly cookies with stripped JWT
I have an API server (ASP.NET Core 5) and SPA client (ASP.NET Blazor). Nothing else: no external oauth servers, identity providers and whatnot
To secure access, the server issues and validates access tokens (JWTs) and refresh tokens.
A JWT… Continue reading Should I specify JWT audience and issuer if I have only one SPA client?
I have a stateless backend app, session data is stored on the front-end in a JWT token, so the front-end app passes this token in Authorization header to all the requests.
I need to add 3rd party API integration that will use OAuth2.
I imp… Continue reading Access to JWT session after OAuth redirects
For simple authentication with backend services, without more sophisticated needs (e.g. roles and scopes), is there any security benefit in using JWTs instead of sending HMAC hashes to verify a payload?
HMAC:
Client generates a timestamp … Continue reading HMAC hashing vs JWTs for stateless authentication
Many popular reverse proxies (tomcat, nginx, …) seem to handle OpenID Connect and act as a Relying Party to hide the authentication complexity to all applications behind the reverse proxy, which just receive http headers containing user … Continue reading OpenID Connect with or without reverse proxy?
