How Long is Too Long to Update?

StWaldo asks: "I'm sure everyone knows the story about the life expectancy of an fresh, un-updated PC, once it's connected to the internet. What about a PC which just hasn't been updated in a while? I've been deployed in Iraq for the last 9 months, and haven't been able to hook up my laptop to the internet to get updates (I do HAVE access, just can't hook up a personal laptop, gov't only). Before I deployed, I would update my software (system, anti-virus, firewall, anti-spyware, etc) regularly, but as I get closer to coming back to the States and my broadband connection, I'm beginning to wonder what the life expectancy of my PC will be. What's the lifecycle of a security exploit, hack, virus, etc - between discovery/release, propagation, and extinction (or a state approaching extinction)?"

    1. Put your computer behind literally any personal firewall/router (Linksys, DLink, etc.) that can be had - wireless and wired or both - for under $50.

    2. If you have Windows XP Service Pack 2 (SP2), just make sure the firewall for your network connection is still enabled; it is by default on SP2, and Security Center will warn you if it isn't. Unless you explicitly disabled it, it will still be enabled.

    If you don't yet have Service Pack 2, simply enable the Windows firewall (Internet Connection Firewall) for any network interface(s) you have. This can be done on the Advanced tab of each connection's Properties.

    3. There is no step 3.

    There's nothing you have to do other than ensure you have a software firewall enabled, and optionally have your machine behind a nice little personal firewall/router. Then it doesn't matter how long it's been or what exploits are out there[1].

    That's it. Even the built-in Windows software firewall on a machine with no patches or service packs installed will protect a Windows XP system. Seem simple? It is. One wonders why it took Microsoft *so long* to make it the default.

    [1] Sure, there may be exploits that affect browsers or other aspects of the system that could be exploited by *visiting malicious sites*, but the machine, just sitting there, won't be vulnerable. If all you're going to do is immediately update everything anyway, you have nothing to worry about.

      Simply using a NAT router DOES NOT protect your machine from e-mail worms (like Sober, for example).

      Right. But running a properly-engineered browser (like Firefox) and a properly-engineered email client (like Thunderbird) and not being a complete moron who opens up executable attachments that haven't been virus scanned yet will accomplish that far more effectively than merely updating your system, since the latter is only temporary (until the next exploit is inevitably found).

      Step two is to immediately update your system.

      No, step two is to enable the firewall on the OS.

      Step three is to run as a restricted user and to never run with administrative privileges except to install software. Being forced to explicitly log in as administrator forces you to think about what you're doing. That alone is worth the price of admission.

      Virus scanning everything you download from the internet prior to executing it, combined with running a firewall both on the machine and right in front of the internet connection, will eliminate most of the risk. Running as a restricted user on top of that will eliminate almost all of it.

      Remember: the reason all of this is an issue to begin with is that Microsoft is a piece of shit software company that doesn't give a flying fuck about real security, and only cares in passing about even the appearance of security. The threat level would be order of magnitude less if it weren't for their idiocy.

    An arbitrary time point just to demonstrate the degree of change. The most extreme example's required time period depends on the specific issue - for example, top tax brackets would be compared to the period from World War II to the late 1960s, when they were almost 90% (they fell to under 30% by the end of Reagan's term, rose somewhat under clinton, then fell back down under Bush).

    Exactly. The US *Has* shifted radically over its history, in case you forgot. Remember slavery? Remember when our government's income was due to tarriffs and land sales? Remember when witchcraft was illegal in much of the US? Need I keep going?

    not sure what you're getting at

    Do you not know what bracketted taxation is? Then what are you doing in this debate? Lets back up to income taxes 101.

    For most of the US's history, there were no income taxes. However, a growing movement in the late 1800s as backlash against "robber barons" (the same movement that eventually led to antitrust laws), and the decrease in traditional income sources for the US government, led to the first income taxes. Income taxes initially only affected the rich; eventually more and more of the population was included, but the rich kept getting higher percentile rates.

    The purpose of income taxes, and specificially *bracketted* income taxes (where people fall into a given tax bracket based on their total income) is as an equalizer without destroying the motive to work - and by all standards, it's been an astounding success. Income taxes for the top bracket peaked during World War II, but only fell slightly after that, to just under 90%. They remained this way until the late 1960s - our nation's greatest boom time. The poor barely payed any income tax. During the 1970s, the top bracket fell, but remained above 70%. Under reagan, it plummetted to under 30%, only to raise under Clinton and fall under Bush II.

    The flatter the tax, the less of an equalizer it is. The more bracketted, the more of an equalizer it is. This is known as a "flat tax structure" and a "progressive tax structure" respectively. Bracketted taxes can be better thought of in terms of a tax on luxury. Picture the following scenario: there is no income tax. Instead, all taxes are on purchase. The highest tax rates are on items of luxury, while the lowest rates are on items of necessity. The poor, simply not being able to afford much if any luxury, end up averaging a very low tax rate. The wealthy, simply not able to spend even a sizable fraction of their money on necessity, end up paying a very high tax rate. Now picture this shifted back to the income side: you have the bracketted tax structure.
