A network is simply two or more computers linked together so their files can easily be shared or transferred from computer to computer. The simplest network is the LAN, the Local Area Network. These computers are in the same office or building. A LAN can have virtually any number of computers. You make a LAN when you connect two computers together in your office or at home.

A computer virus is a parasitic program written intentionally to alter the way your computer operates without your permission or knowledge. A virus attaches copies of itself to other files and, when activated, may damage files, cause erratic system behavior, or display messages.

System security is important! If you ask the question, “Who would want to break into this system or why would they want to?,” the how and why of this line of questioning could fill volumes. The “who” could be anyone whether they have legitimate access or not. The “why” is simple: free computing resources, access to data, damaging your system, embarrsing the university. A compromised system can quickly become a liability as it can affect the network or operations on other machines both locally and remotely.

This white paper provides step by step instructions to apply Microsoft patches with Lieberman
Software’s Task Scheduler Pro.
1. Applying Microsoft Patches with Task Scheduler Pro
The MSBlast worm, also called the RPC/DCOM vulnerability, requires that you install a specific version of the patch for each platform you are patching. Task Scheduler Pro allows enables you to copy the appropriate platform specific patch to each of your systems, execute the patch in an unattended manner, and reboot the systems remotely without any further action on your part. Task Scheduler Pro allows administrators to deploy patches across their enterprise much faster than distribution systems like Microsoft SMS. Patch tasks can be created on all of your systems simultaneously, and they begin executing on your systems almost immediately. In a virus outbreak situation, speed is essential.

The Point-to-Point Tunneling Protocol (PPTP) is used to secure PPP connections over TCP/IP links. In this paper we analyze Microsoft’s Windows NT implementation of PPTP. We show how to break both the challenge/response authentication protocol (Microsoft CHAP) and the RC4 encryption protocol (MPPE), as well as how to attack the control channel in Microsoft’s implementation. These attacks do not necessarily break PPTP, but only Microsoft’s implementation of the protocol.

Investigating computer intrusions can be a complicated matter. Attackers are continually hiding their malicious code, erasing or modifying log files, and finding new techniques to minimize the trace evidence they leave behind. After reviewing nearly 200 compromised systems in the last 12 months, I have often become frustrated with the lack of evidence found on victim systems after the intrusions took place. In fact, the exploitation and post-exploitation techniques used by current attackers almost always thwart traditional physical media analysis practiced by the majority of computer forensic examiners.
