Short version: I think that Cisco is overreacting and is being a bully.
Long version follows... Cisco has a press release about the
permanent injunction against M. Lynn. Most of it reads like the usual
PC fluff. However, I take exception to the following: Cisco's
actions with Mr. Lynn and Black Hat were not based on the fact that a
flaw was identified, rather that they chose to address the issue outside
of established industry practices and procedures for responsible
disclosure. Based on available information, I feel that those
words are entirely bullshit and ask that someone (at Cisco hopefully)
point me to those "established industry practices and
procedures" (the phrase implies that they're written down
somewhere). Supposedly Cisco patched the flaw last April, which means
that it was known (or made known) to them before that. If "established
industry procedures" indicates the "Full Disclosure Policy" that was
drafted by Rain Forest
Puppy, then M.L. was well outside of the 5-day waiting period. Or
even the 30-day standard that Microsoft pushed for when that company
last trotted out
responsible disclosure. Or how about eEye's RDP where specific
information is withheld until the patch is realeased? Coincidentally,
eEye's reported process is similar to those of the OIS (Organization for
Internet Safety) (read their PDF for the actual written practices
and procedures) in that specific information is withheld until the patch
is released. So which "established industry practice and procedure"
did M. Lynn violate? Or did Cisco just not like someone airing their
dirty laundry? Just so that there's no confusion about my
"overreacting" opinion, I used that term in referring to the injunction
requirement put forth by Cisco, where M. Lynn never speak at Blackhat or
Defcon again, on any topic. I'd understand if the requirement was
limited to this specific vulnerability. In my opinion, anything extra
is malicious and over-the-top. Neither side has acted with logical
consideration to their actions, both are trying to appear to be "the
victim", and all involved should "get over it".

Tom's
Networking has a good piece going on the Cisco flop-and-twitch. I
consider the whole incident to be yet another go-round in the religious
war called "responsible disclosure". You've heard the arguments from
both sides. You'll hear 'em again. My personal view (at least of this
incident) is that this isn't something that M. Lynn "invented", it's
something that he heard of elsewhere which caused him to do a bit of
research. Some of "the bad guys" already have the info. It's nice to
know that some of "the good guys" now also have it. However, M. Lynn is
probably going to suffer in multiple ways and this incident has a strong
possibility to set a very nasty precedent. Watch for the legal pendulum
to very quickly to one side or the other.

I'm tired of hearing every tech journalist pontificating about how the
flavor of the hour could be used as a channel for worms/viruses/hacking.
Here's a good example. Yes, RSS could be a vector for malware but it's not a likely one. It's not like we constantly wander the Internet in search of new feeds. For the majority of people, their feed sources remain constant. Barring a web server compromise at one of those sites or the author does something really boneheaded, there isn't much risk of worms or spyware sneaking in via the RSS feed. Of course, if the author embeds crap like advertising in his/her feed, then it's another story.

Personally, I think that, while there's probably a legitimate argument
in there somewhere, this
fight is extremely silly. Someone is pissed off that someone else
wants to push television over IP. I think it's silly because I "get my
IP" over the same pipe that I get my TV. The fight is actually an
industry trying to "protect" their income stream and resisting the
economic force created by technological innovation. The situation is
not one that it easily resolved either. "Convergence" involves the
television, telephone, cell phone, wireless ISP, and even the power
companies. Future involvement will probably include the entertainment
industries, various hardware manufacturers and various
governments. With the move to wireless and IPv6, expect those
industries to spend more and more money on legal support and
advertisements. The industry or industries that come out on top will
probably be the one that offers the most to the customer for the cost.
(This usually translates to the company with the deepest pockets.) The
problem in the logic in the article is that Verizon and SBC assume that
consumers will want their IP-over-TV from a local "central office".
What they're currently missing is fledging Internet-based TV shows that
already exist and even have an existing distribution infrastructure
(BitTorrent). However, I skeptical enough that I expect at least one
attempt to Napsterize BitTorrent. So call me a
pessimist.

I'm a bit behind on my work so here's a quick bit of entertainment for you "conspiracy theorists": take a look at the backgrounds of the people that make up the managing board for the .XXX domain and answer the following questions: - Who's worked with each other at a previous comany
- Who's worked at other registrar's and what did they do?
- Who managed a .XXX domain in a previous light?
- How does the old registrar feel about this?
- Who left under "undisclosed" reasons?
- Who's also participated in ICANN?

I managed to make some headway into getting Galleon up and running. My

I found Joe Gergorio's article
during a lecture that I wasn't paying attention to (I was playing with
del.icio.us instead). The article
talks about a method for securing RSS feeds with encryption rather than
password protecting the site. I like the idea but I believe that Joe
did not take it far enough. The idea that should be on the end of his
train of thought is "public key encryption".

Perl.com has a good Bloom
filters, something I learned just this past week. In a nutshell,
Bloom filters are useful in dealing with gawd-awfully-large databases.
A Bloom filter will quickly tell you, accurately, if what you're looking
for is not in the database or, less accurately, if what you're
looking for might be in the database. Shorter version: it's a
way to avoid having to search massive databases for every query that a
user throws at a program.

I appears that Google Earth
downloads are available
again. So many people went absolutely nuts with this free toy, when
they first released it, that they had to block downloads of the software.
I'm willing to bet that the total man-hours of productivity lost to
Google Earth rivals opening day of one of the Star Wars films. Of
course, people have gotten organized so that they can
spend even more time site-seeing vicariously. Some are even excited
enough about it that they'll post Flickr photos about where they haven't been. What's that? A faux-moblog (fo-mo-blog)? (heh)

The following needs a bit of polish but you'll get the idea: Me
disagreeing with Paul Vixie?!?
I guess so. There are justifiable reasons for implementing private DNS
domains, the main one being "community". Or should I say "different
community" or "private community". There are those that like the idea
of not having to play by the rules imposed on them by others. Paul
Vixie makes a good point for against his own argument when he says "So
what? Everybody wants something. I want a pony. Get over it." I bet
your initial response is to think: "Geez! What an asshole!" To
be fair, he said that to just make a point. (I hope.) But it's one of
the major reasons that people set up their own communities and practices.
An example of this: fanatical "don't top post" crusaders have caused
mail list/forum splits more than once. Otherwise, there would be one
Perl list (with Tom in it), one security site (with Richard in it), one
political forum (dissenters will be shot!), one operating system (you'd
not be able to add functions either), and one movie list (we'll tell you
what you'll watch). Yes, another is "money", but you don't have to
play if you don't want to. In fact, those schemes are doomed to fail,
either due to lack of participation or by actions of the-powers-that-be.
(A local here managed the ".biz" domain two years before the powers that
be declared the ".biz" domain to be theirs. She even went before
Congress over the issue. The result: the "official" domain was assigned
to an "official" registrar and the ensuing "switch" caused a lot of
confusion, not to mention emotional responses. I also take issue with
the "coherency" and the "there can only be one" arguments. Coherency
has never been a basic assumption in the design of the DNS system.
"Trust", yes. "Coherency", no. The "There can only be one" argument
is fine for those sitting at the top. For those of us near the bottom,
there are good reasons to modify "the rules". For 50K+ users and a
small IT budget, filtering of porn, UCE or malicious code can only be
performed via DNS poisoning (declaring your server as authoritative for
those domains your users shouldn't be going)(or blocking
spyware/malicious code sources). There also may be a need to set up
private communities. Corporations can (and do) practice "security by
obscurity" by setting up private DNS roots and attaching vhosts to them.
While "security by obscurity" by itself is not a good thing, as an added
layer in "defense in depth", it increases overall security. (Think a
vhost attached to a private domain where the default page responds with
a 404 error. In other words, you have to know about the pseudo root
page to join the community. With added configuration, you have to be
part of the community to "see" the page.) A non-corporate example of
modifying DNS service for a private community is the UCE-fighting
community's blacklists. As an example, a response to a look up on
"40.30.20.10.relays.mail-abuse.org" means that it's listed as a problem
source. While this service is run within the ".org" domain, it could
just as easily be run under the ".bob" domain. As long as people know
how to configure their DNS services to include ".bob", the service would
be just as employable. This technique is also used to distribute
public encryption keys, host databases (think phone or address books),
keep track of hardware/software/books, and just about anything else a
private community might need. It's only when that community tries to
"go global" that they run up against "you can't have it, get over it"
crowd. Paul's response is not necessarily a "bad thing" either. It's
creates an environment for innovation. Invention is not done by "fat &
happy". It's usually performed by someone hungry, curious, frustrated,
seriously bored or even paranoid. So Paul, with or without your
approval (or help) it's being done. Get over it.
