    For those who complain that ISPs end up footing the bill because the spammers don't pay, well, I guess they'll need to be more careful about vetting their customers next time.

    You do realize that includes you, doesn't it? Your activism costs your ISP money which they pass on to their customers. Given the competative market, chances are they can't raise rates very much, so instead they cut the quality or support or add bandwidth limits to the customers (another thing /. loves to complain about).

    Plugging other machines that are non-Windows is not likely to create near as many problems.

    Plugging in anything without a compentent admin can create problems. The hordes of owned Linux machines banging away on ssh is proof of that. The theory is that the company hires competent people to keep the work machines secure and bans all other machines because they have no way to guarantee that the desktop jockey who wants to run his/her own machine can and will do so. It also helps with software licensing issues and means that JeFF!!1! over in accounting doesn't get overly enthusiastic with security, put company documents on an encrypted OpenBSD system, and then get hit by a bus the next day, taking the password with him.

  3. For the server or for the desktop? on Linux and Windows Security Neck and Neck · · Score: 4, Insightful

    The figures mentioneed by the hosting company seem to indicate that the discussion is focused on Windows security on the server side, where it is fairly true that Windows can be about as secure as Linux when both are competently managed. In both cases, there will be someone who knows about the systems taking care of them and ensuring that they're properly patched, firewalled, etc. I personally find managing Linux boxes easier, but Windows can be kept secure as a server.

    Where Windows still falls down security-wise is on the desktop, where the combination of a vulnerable browser/Office Suite along with the fact that the de facto standard way for desktop users to set up their accounts is with administrator priviledges. That turns what would be a non-existant threat on the server (you shouldn't be doing general surfing or office work on a server) into a major issue. Microsoft has made feeble attempts to encourage users and developers to use limited accounts, but the fact remains that reconfiguring poorly written software to work in a limited account is a major headache that the average desktop user is not willing to put up with.

    Microsoft also falls behind [most] Linux systems in that the majority of the software on a Linux box can typically be updated from a single tool (apt-get, yast, urpmi et al) while Windows Update only covers the core OS. Microsoft does have a better system in the works, but that will still only cover MS software.

    With multiple boxes, having an external facing firewall only helps so much. If one of the "protected" boxes gets infected by student activity, it'll run all over the LAN. That's part of why so many places got hit hard by the last couple Windows worms - they had firewalls and let down their internal guard and got pounded by infected internal machines, particularly when users brought in laptops that had gotten infected at home.

    There's a few things to do to limit the problem:

    1. As you said, have an external facing firewall.
    2. Have firewalls on each individual computer.
    3. Configure services to only connect to systems they actually need to talk to. (And obviously, turn off unneeded services)
    4. If feasible, you can have switch level security that prevents unauthorized machines from making connections. (IE block port 135 TCP from desktop to desktop if they're only ever supposed to connect to a server.)

    Your rote suggestion that I use a "full" character set only doubles the entropy of my password.

    Rote? Knowing industry best-practices is rote these days?

    Check your math. The complexity grows exponentially. Your statement suggested that randomness makes a secure password, which is not true. A secure password requires a combination of length and (at least pseudo-)randomness or extreme length.

    A randomly generated 8 character password from the character set {ab} has 256 possibilities. Increasing the set to {abc} increases it to 6561, and {abcd} to 65536. That's far beyond doubling.

    The difference in the average time to force an 8 characted {a-z0-9} set like you suggested (which can be brute forced in about a day (at most) on a standard desktop computer) and an 8 character 95 character set is *4703. That means that a standard computer could brute force it (on average) in a dozen years or so. Which for most people's standards is a big enough number.

    (Note that "good enough" doesn't apply to people who aren't bright enough to properly salt their hashes, leading the possibility of just generating rainbow tables.)

    Non-Latin characters would increase the strength, but at the cost of backwards compatability and usability on systems that didn't support them. A properly designed hash system can accomidate an inifintely long password, meaning that in practical terms you can just add a few characters when you need additional strength. My main online banking password is a 13 character pseudo-random string (it's derived from something, but only in a way that makes sense to me) that draws from the extended character set. It's prolly more memorable to me than your 8 character random one yet provides much, much stronger protection.

    If you're that paranoid about password protected access, you shouldn't use it at all.

    Most things don't offer a practical alternative. I use practical but relatively strong passwords, whereas you made the statement that a simple random password was secure. Simply adding a mix of capital letters to yours would increase the time to brute force by over *72, while not being much less memorable than the original.

    So microsoft says windows is cheaper to patch, whereas Novell (who own Suse) say linux is cheaper to patch.

    Part of it is that it's subjective depending on what you place value on. From an enterprise standpoint where you're rolling out patches to hundreds or thousands of systems, Microsoft has put a lot of effort into making it easy to manage remote updates. Active Directory has a lot of really nice features that are either missing from Linux or a proprietary add-on (ie Novell's Zen). That carries a lot of value to many people.

    To other people the lack of constant rebooting creates great value. As does the fact that distribution upgrades tend to allow you to update the entire system from a single program, compared to the many different ways that Windows software can and has to be updated from.

    It's still not news, but Microsoft has a very valid point in saying that from the enterprise management standpoint for CORE SYSTEM updates, Linux is not as easy and accessable to use. All software has problems. Choose the one that you can handle best and get on with life.

    OS X is worse than [most - assume that the word most proceeds Linux in the following statement] Linuxes to patch in the following ways:

    1. Linux distributions cover the commonly used server tools as part of the distribution. OS X does not include all of the same things, such as MySQL.
    2. Linux distributions can be configured to download and install patches automatically - add the appropriate line to your cron (or your patch management software if it supports it) and it'll pull in and install updates as needed. With OS X, you're required to click-through licensing in some cases, so it can't be done in the same way.
    3. Linux makes separate updates separate patches - I can pick and choose if I want to update package $FOO but leave package $BAR as it is.
