JavaScript OAuth2 Client - Authorization Code Grant

For a PoC, the OAuth2 authorization code grant use case, needed to be stubbed out.  Whilst this can be done over Curl, I decided to build this out in NodeJS to replicate a client application more closely.

The OAuth2 authorization code grant is fully explained here - http://docs.forgerock.org/en/openam/11.0.0/admin-guide/index/chap-oauth2.html#oauth2-authz

Basically there is a decoupling between the resource owner, the requesting client and the authorization server.


My basic client, first of all authenticates the end user to get an OpenAM session token.  That token is used to generate an authorization code, which is in turn used by the client to request access and refresh tokens and ultimately the attribute scopes for the user.

The code is available on Github - https://github.com/smof/node_openam_oauth2_client

WebAuthn Authentication in AM 6.5

ForgeRock AccessManagement 6.5, will have out of the box integration for the W3C WebAuthn. This modern “FIDO2” standard allows cryptographic passwordless authentication – integrating with a range of native authenticators, from USB keys to fingerprint and facial recognition systems found natively in many mobile and desktop operating systems.
Why is this so cool? Well firstly we know passwords are insecure and deliver a poor user experience. But aren’t there loads of strong MFA solutions out there already? Well, there are, but many are proprietary, require complex integrations and SDK’s and ultimately, don’t provide the level of agility that many CISO’s and application designers now require. 
Rolling out a secure authentication system today, will probably only result in further integration costs and headaches tomorrow, when the next “cool” login method emerges.
Having a standards based approach, allows for easier inter-operability and a more agile platform for change.
AM 6.5 has int…

Implementing Zero Trust & CARTA within AM 6.x

There is an increasing focus on perimeterless approaches to security design and the buzzy "defensive security architectures".  This blog will take a brief look at implementing a contextual and continuous approach to access management, that can help to fulfil those design aspirations.

The main concept, is to basically collect some sort of contextual data at login time, and again at resource access time - and basically look for differences between the two.  But why is this remotely interesting?  Firstly, big walls, don't necessarily mean safer houses.  The classic firewall approach to security.  Keeping the bad out and the good in.  That concept no longer works for the large modern enterprise.  The good and bad are everywhere and access control decisions should really be based on data above and beyond that directly related to the user identity, with enforcement as close as possible to the protected resource as possible.

With Intelligent AuthX, we can start to collect and s…

Forget Passwordless, What About Usernameless?

A year or so ago, I blogged about the wonderful world of passwordless and how WebAuthn was going to save the world!  Gone will be insecure passwords, with their terrible user experience, and contributions to data breaches and in with a standards driven, crypto based, technology agnostic way of authenticating a user. The panacea!  Well, the panacea might just be getting be getting a little better.

Take a look at the above blog for a quick "reccy" on how WebAuthn works and the main flows.  TLDR; we're using public/private key pairs for each website or service we want to authenticate against.  The private key gets stored somewhere safe - namely within the dedicated USB authenticator fob, or within the secure element on an operating system.

In ForgeRock Access Management 7.0 EA, the WebAuthn registration authentication node has been modified to now include a "Username to device" switch.  This essentially allows a user handle to be sent back down to the authenticato…
