Subject: FW: Security Index  SECURE SOCKETS LAYER COELACANTH: Phreak Phishing Expedition


Again we see that a factual and independent index of security 
vulnerabilities is needed to objectively assess security in a
complex environment.

I have proposed the Clairmont-Everhardt Index of Security Vulnerability
to be that objective measurement.  As published earlier, this index could
give the Security Manager, CSO or other security personnel some objective
measurement as to their actual Network security within a margin of error.

Right now there is no known objective security measurements that are generally
known.

A paper that is forthcoming will propose as a start: the methodologies
and objectives metrics that could be used in creating a credible 
Index of Vulnerability.   The higher the Index of  Vulnerability
the lower the security of the overall computer network.


Absolute security is never possible, as Six Sigma is the goal in 
manufacturing, these methodologies and goals should be used in securing networks 
on the internet.  


Any useful ideas and contributions would be greatly appreciated and acknowledged.
I look forward to the ensuing discussions and subsequent diversionary humor 
that always results when a serious security discussion is broached on this
rather mendacious forum of paladian mavericks.8->

Really?

Surely you are just being polite?

This is entirely consistent with a long line of shoddy "fixes" from 
Microsoft (and, to be fair, many other vendors).  Instead of seeing the 
"%20 bug" reported by Slemko above for what it turns out it was -- a 
clear indication something was horribly broken in multiple parts of the 
codebase where (HTML) URL parsing occurs, it is now quite clear that it 
was seen as a "there is a problem if '%20' is present in URLs" problem.

When "fixing" the %00/binary null issue recently, was _that_ seen for 
what it really was -- a clear indication there was something horribly 
broken in multiple parts of the codebase where (HTML) URL parsing 
occurs?
