For the small or home office user, retail antivirus programs such Norton AntiVirus 2003, McAfee VirusScan 7.0, and F-Secure Anti-Virus Personal Edition offer adequate protection and are easily managed. But for the enterprise tech with dozens or even thousands of PCs to protect, such products require too much oversight and place too much control with the end user. To resolve this dilemma, enterprises often choose a centrally managed antivirus solution. The most well-known providers of centrally managed antivirus software are Symantec (Norton), McAfee, and F-Secure. These companies each offer enterprise solutions that can be maintained by one or more techs with little to no end-user intervention. Although each product offers a unique set of features, they all share the advantages and disadvantages common to centralized antivirus solutions. Before you recommend such a solution to your boss, however, you should be familiar with these common characteristics. Reduce network traffic and administration time Most virus signature/definition files are somewhere between 1 MB and 2 MB. Not a bad download for one machine to handle, but with just 50 machines, that number jumps to between 50 MB and 100 MB. In addition, stand-alone antivirus programs often require each computer to have an Internet connection. This means opening a port in your firewall (if you have one) for all machines and downloading the same data repeatedly. With a centrally managed antivirus solution, you have the benefit of downloading the virus signatures/definitions and software updates to a single server, thus requiring only one machine to be connected to the Internet on that port. Once the update files are downloaded, the PCs can then pull them from the server and not the Internet. This is an attractive solution for organizations with limited Internet bandwidth or organizations that don't provide an Internet connection for every PC. Not only can centrally managed antivirus solutions reduce network traffic, but they can also significantly reduce the time techs spend on managing the antivirus system and troubleshooting end-user problems related to antivirus software. Asking end users to regularly update their antivirus software can be tiresome at best and downright dangerous at worst. I know of help desks that routinely e-mail end users, reminding them to update their antivirus software, only to be flooded with a wave of “How do I do that?” questions. Worst yet, many end users simply ignore the e-mails altogether. Some IT organizations use login scripts to automate antivirus updates, but this too is often fraught with difficulty as users can close the script's command window without letting the task complete. Because centrally managed antivirus software often runs quietly in the background, no end-user intervention is required, nor does the end user realize the process is occurring. Simply set your organization's update schedule and let the software do the work. A single point of failure Despite their advantages, centrally managed antivirus solutions are not without drawbacks. Because such systems store the virus signature/definition files in a single location—usually a network server—this server becomes a single point of failure for the entire system.
