03/26/08 Don 't Get Tricked into Downloading
Recently, there has been an increase in the number of Lab computers with trojans, spyware and other malicious software installed. In many cases, these infections can be traced back to a user who has downloaded and installed something from a shady website. Two big areas of concern are false video CODECs and deceptive system tune-up utilities or spyware scanners.
If you visit a website that claims you need to have their special CODEC to view their video clips, IT IS PROBABLY A SCAM. Sites like YouTube have been very successful in delivering video without requiring any special software to be installed, and nearly everyone has copied their technique. In almost every case, there is no legitimate need to install anything other than a common video-viewing program such as Windows Media Player, RealPlayer, etc. to watch video on the web. Anything they want you to install is more likely to give them control over your computer instead.
We 've also seen a number of systems with so-called "system utilities " or "spyware scanners. " With names like SafeStrip, System Soap Pro, Spyware Shredder, Spy Sheriff (to name but a few), these applications often do not actually do what they claim. THEY ARE USUALLY SCAMS. At best, they may introduce spyware of their own. At worst, they may contain genuinely malicious software designed to hand over control of your PC. Many even lie about problems they are supposed to have found with your system 's performance or security, in order to entice you to "purchase the full version " to fix them. Remember, JLab already provides Norton AntiVirus software, which includes an excellent anti-spyware component, and our CNI staff are constantly working to keep your computer in good running order.
Please remember that the ability to download and install software onto your computer is something that should not be taken lightly. If you are having trouble accessing some online multimedia resources, think your computer is running too slowly or are concerned that there might be some spyware on your PC, the safest thing to do is to call the JLab Help Desk at x7155. The security of the Lab 's computers depends on you!
04/25/07 Network Registration and Asset Management
DOE cyber security guidelines require that we maintain a database of machines on the Jefferson Lab network. As part of this, users are required to register their machines at this web page
NetManager
If your machine gets its address automatically (DHCP), your machine name on the registration page may be different than you expect, but please proceed anyway. If you are unsure about your machine 's registration, you may visit the above web page to update your registrations.
After May 1st, user machines that are not registered will be in jeopardy of being removed from the network without notice.
Please note that this does not apply to networks managed by the accelerator controls group or machines in building 98.
Users of laptops who access the network in both wired and wireless modes should register on both networks. Machines that are on the network infrequently, belong to another institution, or are personal machines should be registered the next time they are connected to the network. New machines should be registered as soon as possible.
Further questions should be directed to the help desk, x7155, or helpdesk@jlab.org.
Thank you for your help in this process.
