Misuse of Ben Brady's Firewall Log Reporting Utilities
with Ben Brady serves as a perfect case in point:
Throughout the weekend I hoped that this issue would quickly extinguish itself. But instead, Ben Brady's "press release" has spread rapidly throughout the Internet security community (as you'll see). During this time, my position has been without formal representation. Given the content of Ben Brady's note, it is no surprise that our office is receiving a flood of hate mail from angry people who consider me to be acting like a Goliath stepping upon poor David. But, as in any dispute among intelligent people, there is more than one side to the story. The following is mine:
Ben Brady's Statement
apparently decided to take on yet another crusade....
I believe that providing powerful, but brain dead, automated eMail generating tools to uninformed users is the height of hubris and irresponsibility. It has an effect not unlike eMail viruses that now plague the Internet empowered to automatically look up destination eMail addresses and generate specious eMail content. But this is apparently the way Mr. Brady has chosen to pay his bills. While I disagree with the fundamental ethics of Mr. Brady's utilities, I had no complaint with them until the eMail they generate began harassing my company and my ISP. If the generation of such eMail was a good idea, you might imagine that this would be an obvious feature to build into any existing personal firewall in order to give it a competitive advantage . . . but no reputable firewall vendor would, or has, done so. I explained to Mr. Brady that I consider his utilities to be defective because they incorrectly and irresponsibly interpret and judge the content of their users' firewall logs, portraying them as "intrusion attacks", then encouraging and facilitating the generation of specious "intrusion report" eMail. Since contact by my security testing facility is user-requested and absolutely benign, EVERY PIECE OF EMAIL EVER GENERATED THROUGH THE USE OF MR. BRADY'S SOFTWARE which declares our IP addresses to be the source of presumably deliberate "Intrusions" and further characterizes those who innocently visit our site as "Victims" (see the sample report below) is incorrect, has never been correct, and will never be correct. Furthermore, Mr. Brady has known of this problem with his software for at least two months and has repeatedly and adamantly refused to take responsibility and voluntarily correct the situation. I say "voluntarily" here, because in the public comp.security.firewalls newsgroup over the weekend, Mr. Brady stated that he would repair his programs, as I had requested . . .
Here is a sample erroneous "intrusion report" typical of those being continuously generated by one of Brady's defective utilities. This eMail was subsequently addressed to and received by my company and my ISP:
You'll note that whereas firewall logs label activity by "source" and "destination", Brady's program interprets and translates this into "Intruder" and "Victim".
What Did I Ask of Brady? Contrary to his repeated claims, I have not asked him in any form or fashion to censor the reporting of his utilities. I asked him to repair their defective operation (defined as I did to him) by presenting their user with a simple "Windows Dialog Box" mentioning that the firewall log entry they are viewing, and presumably believe represents "another intrusion", apparently originating from an Internet security testing activity requested by the user, in this case the one known as "ShieldsUP! at grc.com." Brady flatly refused to make any such changes during our eMail interchange Friday, and continued to do so in the public comp.security.firewalls newsgroup throughout the intervening weekend. Finally, at my wits end, I explained to him that later this year we would be introducing an autonomous, background, daily security testing facility, known as "NanoProbe". I explained that I was extremely worried that this would tremendously increase the amount of erroneous eMail being generated through the use of his utilities and that absent any changes to correct their presently aberrant behavior, I couldn't see that I had any recourse other than making their non-use a clear prerequisite for users wishing to employ our future subscription service. Because I knew that this was an extremely crucial issue for us both, because I wanted him to have plenty of notice, and since he had, by this time, threatened me with legal action and told me I "would be sorry" if I said anything derogatory about his software in public, I wanted to be very clear with him. So I stated this future problem in the clearest possible language which you read in his public disclosure of our private conversation.
Where's That Silver Lining I Promised? I read through all of the postings there about two pages worth at the time and saw all of the damage being done by Ben Brady's, as yet unrebutted, public statement. At the end of the existing thread, I jumped into the discussion and explained more of the background, as I have here. The tone of the thread changed immediately when people were presented with a more balanced picture of the dispute. And I knew then that I needed to create this page in order to counter Mr. Brady's gross mischaracterization of the situation.
While reading through the online thread, I encountered one of the site's many resident Gurus (1555 posts on the site) who goes by the handle "Wildcatboy" and who has demonstrated his expertise at DSL Reports many times over. His initial posting in the thread was typical of many there at the time, and clearly demonstrated that he had no particular bias in favor of my present situation as he knew of it from Mr. Brady. Excerpting, to characterize his first posting:
By wading through posts like that one, I learned that everyone there was already familiar with a fabulous firewall log analyzing and reporting utility I had not heard of before called "ZoneLog Analyzer". Later in the thread, when "Wildcatboy" learned the details of my position relative to Mr. Brady's utilities, he downloaded a copy of Brady's ClearZone, examined it relative to the familiar ZoneLog Analyzer and with his proven expertise in personal firewalls in a publicly reported message to the group's moderator (see the thread), characterized Brady's ClearZone utility by saying:
"Wildcatboy" subsequently fleshed out and explained the basis for his judgement about Mr. Brady's utilities:
As you can see from Wildcatboy's "before and after" postings, he was originally every bit as poisoned by Brady's public statements about me as were so many others who encountered them. But then, judging NOTHING other than the relative merits of Brady's software, he came to thoroughly understand and support my position and arguments. (And we all agree that having the industry switch over to Matt's ZoneLog Analyzer would quickly solve the problems being created by Brady's utilities.) The "warnings" Wildcatboy refers to in his posting above, would be clear if you were to read through the entire discussion thread at DSL Reports, as you are certainly welcome to do. But, essentially, Brady (and others who support him) have been contending that this is entirely a "user education" problem which can be solved by working to make users aware that not all entries in their firewall logs represent actual "intrusion attacks." The difficulty with accepting this line of reasoning from Mr. Brady is that the entire function of his own software appears to be the parceling out of the deliberately inflammatory labels "Intruder" and "Victim." As we have seen from Wildcatboy's review, unlike ZoneLog Analyzer which significantly aids the judgement of its users, a functional evaluation of Brady's utilities concludes that they exist for the purpose of generating what is probably erroneous and inflammatory eMail.
observer could reasonably draw any other conclusion. While Brady attempts to deflect responsibility with empty rhetoric about "educating the users" of Internet firewalls, the users' experience with Brady's software encourages exactly the opposite result.
The product is currently at "finished late beta" stage and nearing its formal release. It may be freely downloaded and used for no charge at this time. Once Matt, the program's author, decides that it's ready for the world, it will become full-function shareware incorporating a little "nag" dialog to remind its user that with continued use comes an obligation to register and pay. Matt indicates that the cost of registration will be approximately $13 (US). The second bit of silver lining, as disclosed within the DSL Reports thread, is that this discussion has stimulated the programmers and software developers over at DSL Reports to immediately begin working toward the provision of a similarly useful, comprehensive, and responsible utility (they believe it may be freeware!) for the BlackICE Defender intrusion detection system. An evolution of this page will keep track of developments as they progress, and my eMail system will notify its subscribers of these important developments.
It is a complex topic, in need of a careful and concise explanation, with plenty of peer review. It is a need I will address at the first opportunity. In the meantime, in response to many people who felt that a clearer warning about the logging consequences of using the ShieldsUP! site would be a big help, I immediately (earlier today) added language to the pages to explain that the use of our system WOULD CERTAINLY RESULT in appearances in the user's firewall log, if any.
. . . just by glancing at the IP address? Due to the realities of the problem, I hold out very little hope that the typical user running a poorly conceived, automated, firewall log processing program will take notice of our IP address when they are being told by that program that they are victims and that their system has suffered an intrusion. Wouldn't most people just press the "Blast 'Em" button?
less, is socially irresponsible.
a program to assume, not accepting that responsibility is unnecessary. I think that makes it wrong.
In Closing . . . I believe that Ben Brady has been wrong about many things, one of them being that "I would be sorry." How could I be sorry when the ultimate consequence of this event will certainly be improved options, better software, and enhanced education for the typical Internet security concerned personal computer user?
No. I'm not sorry at all. To be kept informed about the development of this new breed of high-quality firewall log analysis and reporting utility, you are invited to join my eMail list. (Click the GRC Mail System icon below.) I never send mail unless I have something significant to report. In the entire history of the system, I have only ever sent seven mailings. |
