The never-ending battle
You’ve secured your network. Congratulations — take the rest of the day off. But come back bright and early tomorrow, because you’re in danger again.
Securing an organization is a process without end. You do your best to keep your network and your clients safe from vulnerabilities, but it’s virtually impossible to seal all the holes.
At ZDNet, we try to provide not only the latest security news, but commentary, analysis, and security products you can download and try. However, there’s often some delay between the first appearance of an exploit and the first report of it in the media. If you’re vulnerable, that time could be critical. Therefore, you should keep a close eye on some dedicated security sites.
SecurityFocus.com is a clearinghouse of security information. It hosts a vulnerability database that lists newly discovered security holes, and Bugtraq, a moderated mailing list that discusses those vulnerabilities. You can also access the Bugtraq archives. There’s probably no better place to stay abreast of new computer security dangers.
A good complement to SecurityFocus.com is Carnegie Mellon University’s CERT Coordination Center, a computer emergency response team whose mission, according to its Web site, is to "provide technical assistance and coordinate responses to security compromises, identify trends in intruder activity, work with other security experts to identify solutions to security problems, and disseminate information to the broad community." CERT too offers a mailing list for security advisories.
You can also find resources aimed at specific kinds of problems. For example, an excellent resource center on viruses is Symantec’s Antivirus Resource Center.
But don’t act on security alerts without a little forethought. Before you start e-mailing the entire company about a new vulnerability your friend in Silicon Valley just sent you a message about, make sure it’s legit. Sometimes hoaxes are just as vexing as real problems, because users buy the scam and pester IS staff with questions or requests. Forewarned is forearmed — check whether the latest alert is a hoax.
Plan, implement, and test your security countermeasures, but stay up-to-date. And if you have any favorite sites or defensive tools, please share them.
