In the Department of Defence Rainbow Book Series: A Guide To Understanding
AUDIT In Trusted Systems (1988). There is a part in the book that explains
trusted systems audits using write-once media -- CD-Rom. This prevents
crackers from inflitrating computers and changing their contents. I believe
this is what major "public" web sites should use for there homepages to keep
them from being altered.
The Web server would have to be based on all write once media -- from the
Operating systems and all other aspects, otherwise the attacker would just
redirect the homepage contents to a hard drive.
this would prevent any altering of pages. A cracker could still bring down
a site--just not put up altered pages.
