Our libraries now function as an essential vehicle for ensuring that a diverse public has access to the Internet. Yet, we face an unending task of maintaining security for the technology we now support. Connecting your library network to the Internet introduces security concerns that require valuable technology resources. The recent attack by the W32/SQL Slammer worm, also known as "Slammer," slowed and, in some cases, stopped Internet traffic worldwide. This worm attacked servers rather than individual computers, but reminds us again that protection and security are absolutely essential even at the individual computer level.

There are several ways you can protect yourself from malicious hackers and users. Here is a brief list of the software security options available for the Windows, Macintosh, and Linux operating systems. These span a range of antivirus programs, firewalls, and anti-vandal intrusion detection systems, either alone or in combination.

Windows operating system

BlackICE merges a personal firewall with an intrusion detection system that is designed to constantly monitor your Internet connection for suspicious behavior. It responds by alerting you to trouble and blocking the threat. BlackICE also defeats dangerous programs that attackers deliver through instant messaging, e-mail, or your Web browser. BlackICE automatically blocks attacks by inspecting all information coming into your computer. The program works with Windows 98, XP Home, XP Pro, 2000 Pro, ME, and NT 4.0 workstation.

ZoneAlarm provides a variety of firewall solutions for your network. It also offers ad blocking, which stops annoying banners and pop-up ads from appearing on your screen. Cookie control halts Web sites that use cookies to spy on your online activities. E-mail protection prevents your computer from being infected by, or inadvertently spreading, malicious code. Hacker tracking lets you pinpoint the origins of intrusion attempts. It works with Windows 98, ME, NT, 2000, and XP. To view product information, go to www.zonelabs.com.

Macintosh operating system

Norton Internet Security protects your computer and network against viruses, hackers, and other privacy threats. This suite of products includes Norton AntiVirus, Norton Personal Firewall, and Norton Privacy Control. Together these programs provide virus protection, eliminate hackers by blocking unauthorized Internet connections, and safeguard your personal data. The firewall notifies you when someone attempts to access your system, letting you deny access to service, port, or IP address. Version 1 of the program works with Mac OS 8.1 through OS 9.2.2. Version 2 works with Mac OSX. There is also a Windows version for XP Home, XP Pro, 2000 Pro, ME, and 98. For more information on this product, go to www.symantec.com.

NetBarrier takes a four-pronged approach to protecting your system. Its Personal Firewall monitors all incoming and outgoing data. Its Antivandal program blocks attempts to break into your computer, detects wrong passwords, and logs vandal attacks. Internet Filter analyzes data as it leaves your computer and prevents you from exporting private information such as credit card numbers and passwords. An Internet Privacy feature lets you control cookies, and block ad banners and spam. It works with Mac OS 8, 9, and X. There is also a version for Windows 98 SE, ME, NT, SP 4, 2000, and XP.

Vexira Antivirus for Linux workstations uses a multi-platform virus inspection technology that boosts virus-scanning speed. It looks for viruses and other suspicious activity on local hard disks, floppy disks, e-mail attachments, and Internet downloads. It can scan files automatically and block access to infected files. Another version is available for Linux servers and for Windows 95, 98, ME, NT, 2000, and XP. For more information, go to http://www.centralcommand.com/.

It is no surprise that along with the benefits and opportunities that technology brings come some fundamental challenges. Still, our libraries remain committed to providing Internet access and other technical tools to their patrons. While this requires a great deal of attention by an already overwhelmed library staff, the partners of the portal project hope that security information among other tips will allow our libraries to more efficiently and effectively meet the needs of the public and the library community as a whole in a safe and sustainable way.
