“In a move that company detractors said is another sign of
its infamous ‘Embrace, Extend, Extinguish’ strategy, Microsoft has
used an open Internet security standard in its Windows 2000
operating system and made modifications without openly documenting
its changes.”
“Microsoft has incorporated open standard Kerberos security,
which keeps user passwords from being sent over a network where
they can be sniffed and stolen, into Windows 2000, making its
marquee operating system (OS) more competitive with Unix.”
“But in doing so, it has made changes to Kerberos – producing
‘Microsoft Kerberos, which is proprietary,’ said Ted Ts’o, who
helped lead the development team on the network authentication
protocol with others at the Massachusetts Institute of Technology
(web.mit.edu/kerberos/www) in the early 1990s.”
