I added a bunch of courses to PluralSight’s security library – check them out!

    I’ve watched all your PluralSight courses. Great job, thanks.
    When are you going have a course on Identity and Access Control for Web APIs?

    Just finished watching your pluralsight videos – they helped me out massively.

    I’m looking at building my own IP-STS for an enterprise project in the UK. Are there any tips you can give or pitfalls you can advise me of (other than the standard security related problems).

    Thanks very much.

    • Well – writing an STS is very hard work. Check out IdentityServer – or a consultant ;)

      good luck!

        Hi Dominick! I’ve read a lot of your materials – seen all of the pluralsight stuff – all of which is very useful. One of the best features of WIF is what I perceive to be an incremental technology adoptance pattern. You don’t have to go full on federation to start taking advantage of claims – and you can implement more as you fully understand it. One thing that is concerning – is I do see it mentioned a lot from independent sources that writing your own STS is very, very hard. If an STS backed by several different authentication stores is required (including non-AD) – if you already have an RP-FP-IDp scenario working – if you already have a system for provisioning users, provisioning RP’s, if you already have fault tolerance and load balancing worked out – if saml11 is more than ok for the foreseeable future for a given environment – if you have all the different levels of encryption worked out – and things seem to be working really well – is there some stealth issue or major concern that is not mentioned in any of the standard materials that we should be looking out for? Something that is a deal breaker and is a real gotcha for any developer who dares to spin his own sts?

      • Well – just keep in mind that you are writing security software – and big parts of your application infrastructure depends on it. Then you’ll be fine ;)

    Hello Dominick,
    Maybe you could suggest or advise the best route to follow. I would like to know when using WCF and Web API what approach should i follow in terms of security. We have two ways in which our methods would be called, 1. Via the www and 2. Intranet. (Within the domain).

    Your Pluralsight videos are great. I’ve watched them all :-). Have you written anything about use cases where several users can read the same kind of data (like a list of documents), but access to each document is restricted to a subset of users. I don’t see how one can get this kind of access control separated from the business logic, like annotating a method in the controller using ClaimsPrincipalPermission annotation for instance.

    I have a Pluralsight subscription and am actively absorbing as much of your material as possible in order to use it in an enterprise scenario. I notice there are no videos with your identity server in the title. Do I need the idsrv STS to successfully federate my web API app?

  6. Course will be available next week or

    I have taken all of your courses thus far and I am currently in the middle of the ASP.NET Web API v2 Security course. I have learned a considerable amount from your courses and they have helped me considerably in my own development work

    I have a question about the ASP.NET Web API course. In the demo for client certificates during module 4 (Classic Authentication and Katana Authentication Middleware) you demonstrate a considerable number of options on your extension method to execute your certificate middleware. However, I never see you actually show the extension method code. My company does not give me a full subscription so I cannot download the code either.

    I was curious to know if there was an easy way I could see that extension method simply so I can understand how you are setting things relating to certificate validation. Like the option to not check Revocation, or the separate custom ThinkTecture options where you can set your own Validator function. I am just not getting how your extension method is gluing the Startup parameters to the Cert Authentication Handler.

    Thanks for all the good work you do. I have learned a ton from your courses.

    Any chance you will be updating courses for .Net Core? Are there any out there now that you recommend?

    I’m working on ASP.NET Web API. I want to create self signed certificate that works both on Chrome and IE. I tried creating certificate using IIS and bind it with default website but it didn’t work. While researching I got to know that CN (common name) of certificate should the host name. so I tried the following way, using make cert

    makecert.exe -r -n “CN=DevRoot” -pe -sv DevRoot.pvk -a sha1 -len 2048 -b 01/21/2010 -e 01/21/2030 -cy authority DevRoot.cer pvk2pfx.exe -pvk DevRoot.pvk -spc DevRoot.cer -pfx DevRoot.pfx

    Create root certificate and then

    makecert.exe -iv DevRoot.pvk -ic DevRoot.cer -n “CN=%1” -pe -sv %1.pvk -a sha1 -len 2048 -b 01/21/2010 -e 01/21/2020 -sky exchange %1.cer -eku pvk2pfx.exe -pvk %1.pvk -spc %1.cer -pfx %1.pfx

    passing in “web.local” as parameter. I changed my host file and make the entry “ web.local”. Now the url https://web.local works in IE and open default website but chrome is throwing a warning with error “ERR_CERT_COMMON_NAME_INVALID” and following error.

    This server could not prove that it is web.local; its security certificate is from [missing_subjectAltName]. This may be caused by a misconfiguration or an attacker intercepting your connection

  10. Is there any plan to update the JWT/Oauth2/OIDC course with modern OIDC developments? The OAUTH2 sections of the course are outstanding, but given the course was produced before the final OIDC specs were launched (Feb 2014 according to there’s definitely a sense that the course content on OIDC could be more robust.

    Hi Dominick, I subscribed as a low level patreon for IdentityServer and have enjoyed your Pluralsight courses. I was wondering – could you do a Pluralsight course on IdentityServer4 or some videos on what’s going on in the code? I’ve debugged through it quite a bit while implementing logons with client webapps in my project, and still don’t understand a few things like server side cookie handling.

    • Hi


      I have not planned any video training anytime soon. It’s very time consuming to record those videos.

      wrt cookies – I don’t think we do anything special with cookies – we just use the standard ASP.NET Core cookie facilities. If you have a specific technical question – the issue tracker on github might be the best place to ask.

    When are you going have a course on IdentityServer 4 and Access Control for Web APIs?

  13. JP says:

    Awesome course! Any plans to do the similar Course in Asp.Net Core?

    Hi Dominick .. your OAuth 2.0 and OpenID Connect lectures are spot on! Just starting the Pluralsight course now.
    I have a question i could really use some help with. See below. Thx in advance if you are able to comment.
    I have a mobile application (xamarin droid/ios) that is integrated with a .net Core 2.2 based webAPI implementation of services. The App authentication is currently using id/password login using core identity services and JWT.
    I need to add “sign-in with” Google/Facebook and Twitter using OAuth 2.0. I’m trying to find a good example as a reference implementation of what i am trying to do here. Basically i’m trying to understand how i can use the token returned from google to authorize access to my apps API? Every demo/example i have found seems to end by showing that it can be done??? but i’ve not found a good explanation of how to go about it. Do i somehow register the google/facebook etc. token/user in my AspNetUsers, AspNetUserLogins, AspNetUserTokens tables?
    Does Xamarin.Auth help with this process? Thanks if you can help clear my mis-understanding.
    Early stages of development with our company so our company website is placeholder only.
