    Absolutely wrong!

    The authors and publisher of a newspaper has no moral right to determine how I use my lawfully acquired copy of their newspaper. It's up to me if I want to read it, discard it, or wad it up to aid starting wood burning in my fireplace.

    Likewise, Microsoft has no moral right to determine is I use Word to write a business letter, or write advertising material for products I might sell, or any other function. How I use the copy I have legally obtained is up to me. The author has absolutely no moral right to dictate how I make use if it.

    In fact, I would argue that it is morally obectional for authors to attempt to control exactly how people may make use of their works, after having lawfully obtained them.

    There is a distinction between using work and publically performing it, such as movies.

  3. Re:What is a PGP signature? on Microsoft Releases 'Caller-ID For Email' Specs · · Score: 1
    PGP is not designed for the same purpose as Microsoft's Caller-ID and SPF.... to determine if the transmitting server's IP number is an authorized transmit point for the domain claimed as the sender.

    A PGP signature will be vunerable to replay attacks if it does not sign the message body, or at least a good portion of the headers. So using PGP (or quite likely Yahoo's domain keys when they finally release the spec), you can not detect that the transmitting MTA is not authorized to send BEFORE wasting the bandwidth to receive the message. SPF can do that. Caller-ID probably can too...

    PGP requires the secrecy of the private key to be maintained. Maintaining and managing secrets is costly. Caller-ID and SPF do not require keeping secrets.

    PGP also requires costly computation, which is costly for servers that handle a large volume of mail.

    There are numerous other problems with deploying PGP or a similar crypto system, which have been discussed over and over on the SPF mail list.

    IMHO MS is reinventing a wheel, or trying to own it.

    Well, they've apparantly been working on this for 1 year... so they began roughly around the time RMX, DMP and SPF began in a serious way. It would only be fair to characterize their effort as reinventing the wheel if a viable wheel existed around the timeframe they began.

    Maybe the idea that mail could potentially be completely private (read:encrypted) is not that appealing to everyone.

    MS's Caller-ID and SPF (and the earlier DMP and RMX that SPF has effectively superceeded) are sender authentication systems. They solve the problem of spoofed headers, commonly used by spammers and email worms/viruses, which is a very widespread problem in need of a solution.

    PGP, as it is applied today, does not solve header spoofing.

    PGP also solves the problem of unauthorized reception. But that simply is not a widespread problem. Certainly not on the scale of spam and email virus propagation.

    Is is true that strong crypto is illegal in many countries, which is also a great problem in its widespread acceptance. MS Called-ID and SPF do not suffer from that problem.

    So, tell them you read it here first.

    Nope, sorry. Many others have thought of this before.

    (Or point me to a similar idea.)

    Try the SPF mail list archives for recent, relevant discussion. There are numerous other lists with older discussions on using PGP and similar systems for sender authentication.

    Yes, you are absolutely correct. This approach you describe, and which is implemented in the sendmail milter, is indeed very effective in filtering out mail.

    It's effective against spam too.

    Let's bash the shit out of MS.

    I'm the one who submitted the story that Timothy posted.

    Microsoft damn well deserves some bashing. They didn't fix the phishing bug in their monthly patch set, and the phishing bug was reported very close to the beginning of that monthly cycle, and only 1 week after it was discovered, scammers started making heavy use of it in their attempts to defraud people of banking details. So Microsoft had 3 weeks to witness the phishing bug being abused in the wild, and still they did not patch it almost a full month.

    This all comes on the heels of a bunch of PR Microsoft spewed not long ago, claiming a study (they paid for) found that Microsoft issues patches faster than Redhat.

    I call them a bunch of lying hypocrites who only care about money and not the security of their customers. You call me a Microsoft basher. You are right, I'm saying Microsoft sucks and the lie. I believe I am right too, they do suck and they do have little regard for honesty, as can plainly be seen.

    In fact, you can do that while installing the 35th sendmail patch this week. Or the 54th SSH.

    In fact, the last security patch for sendmail was on September 17, 2003. That's over 4 months ago. There have been zero sendmail security patches this week, not 35. The previous patch was released March 29th, 2003. Not the same week, but 5.5 months earlier.

    OpenSSH doesn't have the same web pages with patch info as Sendmail... so looking at Redhat's update history on OpenSSH, I see new RPMs published on the following dates: 17-Sep-2003, 16-Sep-2003, 04-Jul-2003, 14-Feb-2003. It's not clear if these are security updates or other less serious updates. But only once did two patches appear in the same week. On average, it's over 2 months between updates.... hardly 54 in one week.

    Now compare that the MSIE. Microsoft's customers complained that multiple patches were required every week, so they recently switched to a monthy patch schedule. But there was news coverage that shortly after the switch, they still had to break that schedule and release patches more frequently because of very critical security bugs discovered.

    And remember that Microsoft doesn't even bother to fix things like this phishing bug, which makes it easy for scammers to direct people to false banking login pages and have them appear to be the legitimate websites of the banks people trust! Contrast that lack of concern for customers getting ripped off against some of the openssh patches, which fix timing problems where the sub-milisecond delay changes could theoretically leak info if probed repetitively probed over a low-latency LAN.... but virtually impossible to attack over the internet, and no known exploits in use.

    It's pretty clear which software has a good security track record and which software has more holes that swiss cheese. It's quite clear who deserves to be bashed.

    It's already been established that Mydoom installs a backdoor and allows routing of tcp/ip connections to mask the identity of the originator. More or less exactly what scammers hoping to defraud ordinary people of banking details (phishing) need. Also the standard approach to turning machines into a valuable asset that can be sold to spammers in need of mail relays or "bulletproof hosting" for their websites that host the images all those spam messages reference.

    Attacking SCO is a smart diversion.... especially if SCO takes the bait and publishes a flamebait press release (seems almost certain), which will of course provoke a response from the free software / open source communities.
