The biggest factor in protecting your machine -- and everybody else in the department -- is YOU!  There are several areas to pay attention to, but in truth, it's all pretty easy... Virus Protection Make sure there is a virus scanner installed on your PC, and configured to do auto-updates. If the CSE Support Group configured your Windows PC, they already installed the McAffee virus scanner, and it is configured to automatically update itself daily. If you configured your PC, make sure you INSTALL a virus scanner. We recommend that you configure your scanner to auto-update on a daily basis, but if for some reason you don't, you must UPDATE your virus scanner frequently - i.e., daily. McAffee typically has an update to deal with a new virus very soon after it is unleashed on the world, and the update process is pretty painless (especially if you configure it to happen automatically, in the middle of the night.) Keeping your virus scanner updated is the best thing you can do to stay safe. Thinking before you open an attachment is the other best thing you can do (more on this further down this page.) Windows Security Patches If your system is a member of one of the CSE windows domains (CSERESEARCH & CSEPCLAB) then your computer is automatically update with the latest security patches. The latest Windowsupdate processes also update your microsoft applications that you have installed, like IIS, SQL, and Office. For information about Windowsupdate, follow the links in the left pane. Spy Software Destroyers Many of you may not know it but on any daily basis, your machine is inundated by various programs, tracking cookies, trojans and the like that are distributed via seemingly harmless web pages and file sharing applications (Kazaa, BearShare, etc...).  The past few months has seen a gigantic rise in this thus creating a whole new bread of applications built for the distinct purpose of cleaning your machine of garbage.  One of the best rated and amazingly enough **free** applications is "SpyBot Search & Destroy" by Patrick Kolla (donations appreciated).  We've tested this application and it seems to be as safe as anything else out there.  It also received the best reviews in one of the newer PC Magazine articles. Special Software If you are running any special software that utilizes the network/internet (Apache Web server, MYSQL server, etc) you *MUST* keep those applications patched. We have no way to update these packages for you. Even applications like Mozilla Firefox and Thunderbird can be gateways for hackers to get into your computer if you don't keep them patched. Enable Windows Firewall A firewall protects your computer by blocking incoming traffic and prevents infection from attacks directed towards your computer. All recent versions of MS operating systems now come with a nice firewall built in (XP SP2 and Win2k3 server SP1). Machines that are built and joined to the CSE domains (CSERESEARCH & CSEPCLAB) automatically have the firewall enabled. You are allowed to make exceptions for programs that you need. For information about configuring windows firewall, follow the navigation links to the left. THINK!  Before Opening an Attachment Be careful about opening attachments that come in email or ICQ, or files you download from the net, or that you get on a floppy. One simple rule is to check the extension of an email attachment. If the extension is .vbs then it's not a web page, it's a Visual Basic script that will execute as soon as you try to open it. And chances are very good that the effect will be very bad. Some viruses come packaged as screen savers (.scr). Word documents can contain macros with hidden viruses. You get the idea. A second simple rule is to pay attention to the sender of an email message, and whether anything strikes you as a little bit odd. Many viruses propogate themselves by first opening a person's address book and sending itself to everyone in there. Thus, you may receive a message from someone you know or have corresponded with in the past, buy maybe haven't heard from in a while. So if a message seems to come "out of the blue", or the message itself seems a little odd, BE SUSPICIOUS ! Contact support if you have any doubts.
