Ask Slashdot: Preparing For Windows XP EOL?
An anonymous reader writes "As most of us working in IT may know, Microsoft will stop supporting Windows XP on April 8th, 2014. Although this fact has been known for quite some time, XP is still relatively popular in companies and also enjoys noticeable marketshare for home users. Even ATMs are running XP and will continue to do so for some time. A lot of companies/users don't want to change because they see no additional benefit to do a costly upgrade, no reason to change a running system, and they may in some cases be right with their assumptions. So what is the best way to secure this remaining Windows XP systems? Installing the latest security patches, checking firewall status and user permissions etc. should be fairly obvious, as Microsoft Security Essentials may also not receive updates anymore, changing antivirus programs seems a sensible thing to do."
Use Firefox. Keep the biggest attack vectors up to date (Adobe stuff in particular). Get rid of Java entirely unless you desperately need it; in that case, keep it up to date religiously. Use Adblock Plus (or equivalent) to block ads which sometimes carry malicious code. Don't do stupid things online. Don't run executables unless you absolutely know they're safe. Don't install pirated software since pirated software sometimes comes with lovely surprise infections. Use a limited user account for your daily activities and an administrator account only for maintenance tasks or to run software that won't work under the limited account. Always use a NAT router between the computer and the Internet, and don't run any open wireless network with that PC attached.
It's largely just a matter of (A) don't do obviously dumb things and (B) don't run everything as an administrator in the first place. Remember that antivirus and security software is a final line of defense; everything else is basically a problem with the user's behavior or knowledge, and if you are careful and follow good security practices in the first place, you aren't at any significantly greater risk than you are now.
One more thing: if someone really wants to break in, they will. XP or 7 or 8 or 8.1 and all the updates in the world won't matter in such a case, so my final piece of advice: don't piss anyone off that might want to come after you.
At my company we have dozens of $500K+ machines that are controlled by NT 4.0 boxes, and dozens of somewhat newere $2M machines contolled by XP boxes.
The vendor has no incentive to upgrade their software to work with a new OS, they'd rather we spend several hundred million on new equipment. And the software that controls the machines is closed and proprietary to the vendor.
We'll still be using NT and XP in 2020.
