Real Security?

An anonymous reader writes "A recent article at Ask Tog raised the common argument about how much security is good. Tog says: 'I've been watching security people for years as they've slowly increased the security of everything they can get their hands on until any idiot can wander in.' Is this the case? Are we increasing security too much, so that the users circumvent it? Should we be allowing simple passwords?"

      Tier 2 passwords are passphrases for my ssh keys for non priviliged accounts. These are the same for 2 or 3 boxes, and again change every 30 days. When I expire tier 1 passwords, they are sometimes moved down to tier 2 for ease of remembrance, tho never for the same servers.

      Tier 3 passwords are for websites, like this one. Usually most of my website accounts share the same login details, as Im not really bothered if someone logged onto slashdot and stated that im a gay faggot or whatever. Tier 2 passwords are usually passed on when they expire.

      I tend to treat passwords as something like special email addresses. You rarely forget an email address because its in a known format: something @ something . something.

    No shit! At some places I've worked, passwords are required to contain X capital letters, Y numbers, and changed once a month. So what ends up happening? After forgetting the damned thing two or three times, most users (including myself, bad form I know but hey) come up with a pattern to their passwords. So, something like this begins to appear:

    Pa55J4n
    Pa55F3b
    Pa55M4r
    Pa55Apr

    Sure, now you have 'secure passwords', but once someone recognizes the patter... This, IMHO is counter productive security wise. Have the ultra secure passwords, but don't make you're users change them too often or this shit begins to appear.

  15. I use good passwords, and here's how by kaan · · Score: 5, Insightful

    And I have to spend nearly zero brainpower remembering a password. Here's what I do...

    Take a phrase (song lyric, phrase, personal mantra, etc.) and grab the first letter of each word. Then replace various letters with numeric digits.

    So an example phrase might be: "i love to post on slashdot"

    which would become: "iltpos", but then you could replace the "o" with the digit zero (0), and the "s" with the digit five (5), so now you've got:

    "iltp05"

    That's basically an unintelligible password, yet totally easy to remember because all you need to remember is your password geneation scheme and a tip for what your phrase is.

  16. Moore's Law vs. Evolution by Detritus · · Score: 4, Insightful
    Long and complex passwords are a waste of time and do little to increase security. Computer speeds have grown at a rate much faster than the user's ability to memorize "secure" passwords. Any system that allows an attacker to use brute force guessing or dictionary attacks is broken.

    My bank gave me a random 4-digit PIN for my ATM card. Why isn't this horribly insecure? Because the ATM eats the card after three failed attempts to enter the correct PIN.

  17. Password management by montey · · Score: 4, Informative

    I recently read a document proposing an alternative approach to an aspect of password management. I have since adopted this approach.

    The paper said that one of the biggest threats to password security was the frequency that changes were required.

    It seems that a fairly accepted norm is coming in to being in the form of organisations requiring their users to role their passwords once per month, and requiring that these passwords are unique. The problem with this requirement is that people are asked to remember so many passwords that they are tempted to either use weak passwords, or to write them down and stick them to something. Hence the previously secure password is now compromised.

    The document/approach I read/have adopted is to stop requiring users role their passwords every month. I now request users to role their passwords every 3 months (once per quarter). As a result in any year they have to get to know only 4 passwords (instead of 12), and as such can handle better quality passwords more easily.

    My users are far more happy with this approach, and now see it as a reasonable compromise. As such they now buy-in to the concept and we find far fewer people breaching the password policy.

  19. security is about economics by sir_cello · · Score: 4, Informative


    Security is nothing special in itself, it's just another aspect of a problem: all problems have many aspects and as you suggest, usability is another aspect of a problem. Turn the technical aspects of the security lever the wrong way (e.g. too frequent password changes), and you lose on usability, and this potentially has a negative impact on the social aspects of the security level (e.g. the passwords are written on a post it note).

    Really, it is about economics and engineering: using the measured amount of resources to solve the problem holistically: technically and socially - understand where all the impacts and flexibile point are. This is no easy task though. Peter Neumann and RISKS have been teaching us these lessons for many years - so there's nothing new here, but it is important to continually reevaluate.

  20. Password Safe by Anonymous Coward · · Score: 5, Interesting

    I've got hundreds of randomly generated passwords stored in Schneier's Password Safe (actually, it is a sourceforge project now). I don't have the faintest idea what any of them are. All I remember is the single password for Password Safe, which happens to be a 20+ digit combination of words, initials, numbers, and a couple of symbols -- all of which are easy for me to remember.

    The password db is blowfish encrypted (yes, there are some cracking programs out there for it, but I'm not trying to keep the info from the NSA). Only two requirements: 1) don't forget the main password, 2) backup the Password Safe db to multiple places.

    The only passwords I remember now are my ATM PIN number, the Password Safe pwd, and that single pwd that I use for every web site that demands registration to function (where I use a fake name as well).

  22. Don't know my own password by soloport · · Score: 4, Insightful

    Honest, I don't know any of my passwords. If someone were to ask me for my password, I'd have to first find a QWERTY keyboard, sit down, place both hands in the right position on the keys and start typing into a text editor. The pattern I type is sort of a rhythm and can be typed very quickly.

    I've been accused (Solaris Sys Ad) of tricking the computer into not needing a password for my login name -- because I type it is so quickly, it seems like I've just typed some random gibberish (which I sort of have). Keeps lookers guessing, too. My typical passwords are 12-18 characters in length -- but they seem a lot shorter ;-)

    As you've no doubt guessed by now, I love this method. I can also "memorize" dozens of unique passwords and never seem to forget one -- even one I haven't used in many months! When I see passwords like "password7", I just smile; Seems to me, mine are just as easy to remember.

    Just hope I don't someday encouter a Dvorak!
