Future Defenses: Technologies to Stop the Unknown Attack Current anti-virus software, combined with sensible filtering (such as quarantining all executable content from e-mail and Web traffic), firewalling, and religiously maintaining patches, serves as a reasonably good defense against the current classes of virus, worms, and script kiddies. This malware includes conventional file infectors, mail worms, people running attack scripts, and active worms based on old security holes. Unfortunately these techniques are not sufficient to stop a speed-optimized active worm based on a previously undiscovered security hole.

Anti-virus Software: The Challenge of Being Prepared for Tomorrow's MalWare Today Defending ourselves against MalWare is obviously a daunting task since depending on your preferred source of information there are between 30,000 and 63,000 known viruses out there. As discouraging as this may sound there is also no shortage of good advice on how to establish some lines of defense and how to recover if your defenses fail. One of the common themes in this advice is to select and deploy at least one and possibly more Anti-virus Software packages. So just what is an Anti-virus package and what will it do for you? Is there a way to measure the efficiency of a package short of buying it, installing it and just crossing your fingers? And finally, in an environment where viruses are increasingly more sophisticated and more easily spread is Anti-virus software up to the task of defending us against tomorrow?s threat today?

Anti-Virus Strategy in a Public K-12 Educational Environment In today's private industry, it is imperative to have virus protection on all of the organizations electronic resources. Corruption of data means loss of revenue and possibly your job. Unlike private industry, public K-12 educational institutions rely heavily on government funding and community fund raising. This means that many K-12 educational institutions have very limited budgets that restrict their ability to use the latest and greatest in virus protection technology. This also means less money to hire enough qualified resources. School boards are often left with hiring temps, contractors, and even parent volunteers to help maintain sometimes very complex networks.

Securing the Symantec LiveUpdate Administrative Utility on Windows 2000 This paper describes in detail the steps required to implement and harden a Symantec LiveUpdate server on a Microsoft Windows 2000 platform. Such a server can greatly reduce the bandwidth required by Norton Antivirus client machines across a campus or enterprise network. It can also prevent denial of service attacks against Norton Antivirus client machines and control the rollout of virus updates. Like any server connected to the Internet, it should be hardened (turned into a bastion host) in order to prevent malicious outsiders from accessing and exploiting it.
