"In the computer industry, there are three kinds of lies: lies, damn lies, and benchmarks."
The Jargon File, 4.4.7, Eric S. Raymond
http://www.catb.org/~esr/jargon/html/B/benchmark.html
I agree entirely with Ofer's first paragraph below, but the example
in the second paragraph isn't a "benchmark".
If you want to know the "quality" of a web application security tool,
scanner, WAF, source code analyzer, pixie dust, "enterprise anomaly
detector", you mean the term 'quality' in regards to the ability
of that tool to accomplish some goal.
My goal in evaluating automated testing tools may be roughly defined:
"Ability to accurately identify software defects that lead to specific
security implications of the kind that a tool claims to detect."
I /am/ interested in a global catalogue of software security defects
that lead to security implications, and evaluating tools against
the kind and degree of catalogue defects they detect.
However, at this state in the industry there is no global catalogue,
no consensus, and I am more interested in evaluating whether or
not a vendor that claims to detect/block XSS attacks does do so.
There are several types of "benchmarks" that have value:
1) What does a widget do on the applications you need to use it on?
2) What does a widget do in relation to its claims?
3) What does a widget do in relation to its competitive landscape?
"Additionally, you will not know in advance what the security problems
are (but than this is the reason to choose this method: neither will
the tool makers)."
Downloading an opensource (src='random') package and running a tool
against it to analyze results provides a benchmark of the type:
4) What unquantified results can this widget produce from random input?
Unless you go through that application manually and know *exactly*
what it is you are looking for I find limited value in those results.
Again, though, we need to more clearly define the target here before
we go off shooting holes in random source.
note: I think most of us on this list agree here, but certain vendors
are still performing their tautological magic shows on pre-built apps,
or pulling the (src=$random) stunts for the uninitiated buyers.
