•Items that should be accomplished before the beginning of the current time frame:•Activities
• Document/Inventory the computers in preparation for Installation in week 4
• Control Panel System, and Control Panel System\hardware\device drivers
• Focus on CPU, RAM, video, monitor, and Network cards for now.
• Discuss virus, trojans, worms; types of attacks on networks, anti-virus, anti-malware, anti-adware, etc.

3 NETWORKING
Peer to Peer
Client Server
| Note: In this class We will set up two servers, and we will create two small small networks; however we may NOT install, or activate, ALL the available features or services discussed. This is partially due to limits of raising servers within an existing network... not having enough computers to connect your server too, the lack of fully licenced software, and/or issues with the campus DNS and real security fear of the campus admins over rouge networks suddenly appearing; these are not scenario you encounter in the real world; we just have to live with it. However, this has no impact on your learning... once you turn on a service, you get the idea of how to turn on other services... the server does the work. Therefore you don't need to turn on DNS, just understand what it's job is; you don't need to turn on remote access, it is just a matter of activating the included software in the server and a client. You don't need to turn on a dynamic disk to know its benefits and limits... a picture showing you what it would look like after the conversion is just like looking at the dialog box after conversion, as the server won't appear to work any differently. So, this class is a lot of theory, and after installation, a lot of looking to find where we could turn something on or off. Recall, while this is an upper division class at a two year school, this is a fairly low level class at a four year school... just understanding what a server can do after installation is the majority of the battle! |

Antivirus info, by Larry Dignan http://blogs.zdnet.com/BTL/?p=32789&tag=nl.e539
BitDefender is one of my favorites on the list. Why? Because it has one of the best graphical virus tools available for the Linux operating system. Of course it doesn’t offer just a Linux solution. BitDefender offers antivirus for both Linux and Windows, as well as for various server installations. In fact, BitDefender has solutions for mail servers, Samba servers, desktops, and much more.
Avira Antivir has, in many cases, found viruses where others have not. One of my favorite uses for this solution is to slap it on a Linux machine (the Linux version is command-line based, but does have a GUI if you prefer), attach an infected Windows drive externally, and run Avira on that drive. Much like BitDefender, Avira will find viruses many other solutions won’t find. And because it is mostly command line, it is also quite a bit faster than other tools.
ClamAV is mostly a mail server antivirus for Linux, but it does a bang-up job. If you’re hosting a Linux-based mail server, you will want to include ClamAV on it; otherwise, you risk winding up spreading the love of viruses around the globe.
Avast is not as much a wallflower as the other tools, but it certainly has never been crowned Prom Queen. It’s an outstanding tool that offers a lot of options many other tools over look. One of my favorite aspects of Avast is the built-in rootkit check. You can’t go wrong when you know your antivirus is keeping you safe from rootkits.
rkhunter is not so much an antivirus tool as it is an anti-rootkit tool. If you’ve never come across a rootkit on a machine, consider yourself lucky. Very lucky. Rootkits are the Mac Daddy of viruses. And if your current antivirus solution doesn’t protect you from rootkits, either add a rootkit protection tool on your system or uninstall and install one that does!
Dr.Web CureIt! is an interesting tool in that it requires no installation. It’s a simple binary file that, when double-clicked, will execute and scan your machine. The only drawback is that to get the latest definitions, you have to re-download the tool and use the newest version. But how easy would this tool be to use as a portable virus scanner?
ESET Smart Security is from the makers of the NOD32 Antivirus tool that has been around for quite some time. ESET sets itself apart by being an antivirus and a firewall in one. But the firewall isn’t just a standard firewall. It’s a “learning firewall,” in that it observes how its users use the network and, theoretically, adapts to that usage. ESET also protects you from removable data and from viruses that attempt to disable your antivirus protection.
ZoneAlarm is an antivirus tool that offers something others do not — DataLock. The DataLock portion of ZoneAlarm uses encryption on your hard drive so that it is readable only by those with the encryption key. DataLock also offers pre-boot authentication so that unauthorized users can’t even boot your machine. Yes, these features can be added from the BIOS or from other tools, but with ZoneAlarm, you have antivirus, encryption, and boot authentication all in one.
iAntiVirus is for — you guessed it — Mac. Like Linux, nothing is immune (no matter how much the media and the PR say it is). And that beautiful new Mac you bought can use protection as well as that new quad-core Windows 7 machine. iAntiVirus is as inherently Mac as you will ever find in an antivirus tool. Not only is it user-friendly, it has that same Mac interface that everyone has grown to love (or hate). And what’s best, iAntiVirus works like any other antivirus software you have ever used — only it does so on a Mac. So it must be better.
Microsoft Security Essentials has to be on this list. After all, it wouldn’t be fair of me to highlight inherently Linux and Mac tools without offering the Windows equivalent. What is really surprising about this antivirus protection is that it is free AND produced by Microsoft. Those two don’t usually go hand in hand. If you want free virus protection, and you want something that will seamlessly integrate with Windows, Security Essentials is your best bet.
