Changes for v1.1 include:<br><b>New / Upgraded Features</b> <ul> <li>We have updated the SecPAL grammar to a new and much more readable grammar. I will post a longer explanation in the coming weeks, but in short when you read a SecPAL policy conditions will now be prefaced by an "IF" statement, and constriaints will now be prefaced by a "WHERE" statement. These changes along with improved readibility of fact qualifiers should make the English representation of your policies / assertions much simpler to read. Note: This change should have no impact on existing policies, as it only affects the output of policies / tokens when you call .ToString() on them. <li>The 'CanActAs' predicate can now be used as a conditional fact within an assertion. <li>No breaking changes were made to API's so any SecPAL dependent code that you have written should behave the same. </li></ul> <blockquote> <h4><a title="The Hogg Blog : SecPAL v1.1 Now Available" href="http://blogs.msdn.com/thehoggblog/archive/2007/06/13/secpal-v1-1-now-available.aspx">SecPAL v1.1 Now Available</a></h4> <p>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 are. The second (which was actually a bug fix) is that our graphical proof graphs now work. </p></blockquote> <p>Source: <a href="http://blogs.msdn.com/thehoggblog/archive/2007/06/13/secpal-v1-1-now-available.aspx">The Hogg Blog : SecPAL v1.1 Now Available</a></p> Cross Posted from Dan Fay's Blog (http://blogs.msdn.com/dan_fay)<img src="http://blogs.msdn.com/aggbug.aspx?PostID=3284610" width="1" height="1">Cool SoftwareResearchGridTech Interophttp://blogs.msdn.com/escience/archive/2007/05/01/linuxinsider-security-microsoft-invites-collaboration-with-grid-computing-research.aspxWed, 02 May 2007 00:25:34 GMT91d46819-8472-40ad-a661-2c78acb4018c:2363315eScience0http://blogs.msdn.com/escience/comments/2363315.aspxhttp://blogs.msdn.com/escience/commentrss.aspx?PostID=2363315<p>Article on <a href="http://research.microsoft.com/projects/SecPAL">SecPAL</a> from LinuxInsider...</p> <blockquote> <h3><a title="Microsoft Invites Collaboration With Grid Computing Research" href="http://www.linuxinsider.com/story/sjtdPLOzASp203/Microsoft-Invites-Collaboration-With-Grid-Computing-Research.xhtml">Microsoft Invites Collaboration With Grid Computing Research</a></h3> <p>Microsoft's Security Policy Assertion Language, or SecPAL, is the company's attempt to develop a language for expressing decentralized authorization policies.
