Unfortunately, the current draft document for the Center for Internet Security
(www.cisecurity.org) Solaris security checklist suffers from the same problem.
It mandates RFC2644 broadcasts, RFC1918 martian and RFC2827 egress filtering,
but I couldn't find any stuff on the victim end of it.
If anybody can provide me with a good reference, I'll be happy to add it and
give credit. http://www.sans.org/dosstep/index.htm is what I have currently
on filtering. If you have a *partial* reference (something that will work
for *many* or *most* sites, for example), I am able to phrase it as
"Evaluate the techniques listed at <URL> for appropriateness".
Anybody got input to add?
