Depending on how it's implemented (much like every other mechanism) it
could have theoretically prevented it from spreading, assuming all servers
were using it appropriately. See this whitepaper for a quick overview:
http://www.research.ibm.com/gsal/tcpa/why_tcpa.pdf
As implemented by IBM, it is nothing more than another means of
discretionary access control. The key word here is discretionary. DAC is a
requirement for TCSEC C2 certification, IMHO the only practical
certification that can be obtained. Mandatory access control (MAC) would
be considered too intrusive (complex) by many and would probably not be
very well accepted in consumer systems.
