		<description><![CDATA[Now that Secure Computing Corporation is a memory, having been acquired by McAfee, I&#8217;m going to write up a few memories of my own experiences. At one point I posted much of this in the appropriate Wikipedia entry, but that&#8217;s actually not kosher. Since much of it is based on personal recollection, these words fall [...]]]></description>

		<description><![CDATA[A SANS Handler Notebook entry by Toby Kohlenberg reports on data leakage in cloud computing, and links to a terrific paper from some UCSD/MIT people: Ristenpart, Tromer, Shacham, and Savage. If we set the wayback machine to the early 1970s, we find a paper by Butler Lampson about something called the confinement problem. It&#8217;s the [...]]]></description>

Ambinder notes that &#8220;Government Blackberries&#8221; can handle classified information &#8220;up to Secret&#8221; but that you need a Sectera Edge from General Dynamics to do anything (voice only) at Top [...]]]></description>

He&#8217;s posted a lot of it on his &#8220;all.net&#8221; web site, which he&#8217;s had since about the dawn of the World Wide Web. What the site lacks in pizazz it makes up [...]]]></description>

		<description><![CDATA[The LOCK project (short for LOgical Coprocessing Kernel) developed a &#8220;trusted computing system&#8221; that implemented multilevel security. LOCK was intended to exceed the requirements for an &#8220;A1&#8243; system as defined by the old Trusted Computing System Evaluation Criteria (a.k.a. the TCSEC or &#8220;Orange Book&#8221;). The project was modestly successful in that we actually deployed a [...]]]></description>
