  • Blog Post: Windows Identity Foundation (WIF) and Azure AppFabric Access Control Service (ACS) Survival Guide

    My friend Alik just sent me to a pointer to a Survival Guide he is working on for the Azure ACS. The survival guide is intended to help provide a standardized means of organizing topics related to a particular domain such as access control. Looks like a good start for anyone working with ACS. Best part...
  • Blog Post: A (Re)Introduction to Patterns

    A couple of people have asked me why I haven't responded to this initial post on the SE Insight site. Partially it was because I recently changed teams and this has just meant that I am crazy busy at the moment. One of the top asks was for a list of good pattern guides - so I figured I would repost this...
  • Blog Post: SecPAL Parser Updated for VS2008 and F#1.9.6.16

    I finally got around to updating the SecPAL Parser to run on the latest version of Visual Studio and F#. Development experience should be much cleaner now because F# is far better integrated into VS. If you run into any problems please post a note or drop me an email. For more information please see...
  • Blog Post: A Graphical DSL for Describing SOA Applications

    Last October we ran a SOA workshop in Redmond, with the goal being to have members of the MCS field, global practices and other customer facing organizations discuss scenarios and patterns that they see on a regular basis. Having run several of these workshops in the psat, one challenge that is hard...
  • Blog Post: Are banks encouraging phone phishing attacks?

    I recently called the support number to verify a charge on my Wells Fargo account and it surprised me when the automated teller requested that I enter my card number and then my pin number. I was always lead to believe that we should never share our pin numbers as that obviously breaches the security...
  • Blog Post: Geneva Identity Management Framework

    For anyone who has followed my blogs around developing an STS or writing authorization policies you will be very interested in Kim Cameron 's announcement at PDC of the Geneva Identity Management platform. Genvea includes: Geneva Framework - A .NET framework for writing interoperable, claims aware...
  • Blog Post: patterns & practices Improving Web Services Security: Now Available!

    Over the last 12 months we have had a lot of people who used the Web Service Security - Scenarios, Patterns and Implementation Guidance ask us where the implementation guidance for WCF was. Great news. JD Meier, Jason Taylor, Prashant Bansode and Rob Boucher and the rest of his P&P team have just...
  • Blog Post: SAML STS for WSE 3.0 (reposted)

    Every week or so I get another email asking where the sample code for the SAML STS for WSE 3.0 has been moved to now that GotDotNet GotNuked. It wasn't moved anywhere. So I figured I would repost it here for those that needs i. For those new to this you should also take a look at Pablo Cibraro's blog...
  • Blog Post: Sample declarative access control policy

    In my previous post I mentioned that we have now released a parser for SecPAL that allows policies to be written in a human readable simplified English grammar. I thought it might be worth including an example - based on the scenario that was used in the GridToday post on Access Control in Grid Computing...
  • Blog Post: Parser for SecPAL simplified English grammar now available!

    One of the great strengths of SecPAL is its unique support for multiple representations of a security policy; XML for interoperability; and a simplified English grammar for human readbility. The SecPAL v1.1 Research Release (available from http://research.microsoft.com/projects/secpal) allows SecPAL...
  • Blog Post: Swiss Army Knife of X.509 Certificate Tools

    Anyone who has dealt with X.509 certificates when trying to design, test and deploy secure Web services will know what an ordeal it can be to locate certificates in various cert stores using different cert identifiers, modify security properties of the private key to allow services accounts to sign or...
  • Blog Post: A Java implementation of SecPAL?

    Panos, from the University of Newcastle just dropped me a note to say that he is making progress with his Java based SecPAL implementation - which is very exciting. I noticed that he has moved away from XSB and has decided instead to create his own custom datalog implementation - which is very cool ...
  • Blog Post: The IEEE Computer Security Foundations Conference

    The 20th IEEE Computer Security Foundations conference is underway in Venice at the moment, and our friends from Microsoft Research in Cambridge (Moritz Y. Becker, Cedric Fournet and Andrew D. Gordon) presented the first paper of the conference - based on their formal design for SecPAL. The paper "Design...
  • Blog Post: Access Control Requirements for Grid Computing Environments

    One question I hear a lot is "How does SecPAL compare with [InsertRandomSecurityTechnologyAcronymHere]?". Well the good news is that Marty Humphrey , Sang-Min Park, Jun Feng, Norm Beekwilder and Glenn Wasson from the Department of Computer Science at the University of Virginia have been studying just...
  • Blog Post: SecPAL Query Editor Now Available

    A couple of people have remarked to us that they like the flexibility that SecPAL provides, but feel that it is difficult for people to get to grips with the API's when they first start evaluating SecPAL. For this reason Lonnie Wall (a consultant from RDA Corp ) has just released some sample C# source...
  • Blog Post: Writing SecPAL Assertions In F# - Contd

    In my earlier post I showed how SecPAL could be used to grant access to a particular user based on a token issued by an STS that we explicitly established a trust relationship with using the SecPAL "canSay" predicate. Now I am going to show you something that I think is really cool - and something that...
  • Blog Post: Writing SecPAL assertions in F#

    I figured I would try to learn F# over this summer - and thought what better way to start than create a couple of SecPAL samples in F#. I thought this might help people that are interested in learning more about F# , or potentially F# users that are interested in learning more about how SecPAL can be...
  • Blog Post: SecPAL v1.1 Now Available

    Just a quick note to let everyone know that we have just released a minor update to our SecPAL library. In addition to a couple of minor bug fixes there are two features which I think you are really going to like. The first is an update to our grammar - making it much clearer what conditions and constraints...
  • Blog Post: SecPAL In The News

    In my last post I promised to walk through a demonstration of SecPAL using a scenario that is challenging to implement using current technologies - but simple to implement using SecPAL. As timing would have it, rather than walking through the scenario in this blog, I can instead point you to an article...
  • Blog Post: SecPAL - Access Control for Grid Computing Environments

    It has probably been around 9 months since my last blog release where I described the release of our ASMX Service Factory. A lot has obviously happened since then - including the release of both WCF and the WCF Service Factory. So what have I been doing since that time? Well, around 9 months ago I...
