  Review: Deep Inspection Firewalls
  6th, May, 2005

If it were on public display, this portion of our Firewall Blowout would be the geek equivalent of the Chicago Auto Show. Our Chicago Neohapsis partner labs focused on the muscle cars: enterprise-class, gigabit-capable network firewall appliances and turnkey systems that support high-availability stateful failover, VPNs and centralized management as well as DI (deep inspection), which we define as having the ability not only to perform stateful packet filtering, but also to inspect packet payloads higher up the OSI model using specific attack signatures and Layer 7 protocol engines.

  In praise of Gentoo
  2nd, May, 2005

On the server end, you get the best release schedule in the business for security updates and bug fixes. On the desktop, you get the latest and greatest packages (if you enable 'beta' packages to be used) like KDE 3.4 (which I'm running), X.org with awesome openGL support, and a nicely compiled nvidia driver. Wonderful. Absolutely wonderful.

  Why Snort makes IDS worth the time and effort
  5th, May, 2005

The decision of whether to implement an intrusion-detection system (IDS) is a complicated one. Unfortunately, IDS has a well-deserved reputation for requiring a lot of "care and feeding" and commercial systems can be very expensive. However, there is an enterprise-grade open source IDS called Snort that may tip the scales over to a "can't lose" position.

  Is VoIP Service the Next Big Target for Hackers?
  5th, May, 2005

Internet telephone service's appeal as a cutting-edge technology for cutting phone costs is convincing more and more people to ditch their landlines and go hi-tech with Voice over Internet Protocol.

Vonage, one of many Internet telephone service providers, says that about 1500 people sign up for its service alone per month.

  Five Linux Security Myths You Can Live Without
  6th, May, 2005

Before I wrote this article, I went to some Linux newsgroups to find out what typical concerns among security-conscious Linux users might be. I asked, simply, what they felt were the biggest myths surrounding Linux security. Boy, did I get an earful! It was as if I had gored someone's pet ox. When I asked about the most common misperceptions of Linux security, I wasn't implying that Linux is any worse, or any better, than other operating systems. There are few "religions," however, with followers as zealous as those of Linux. As with any religion, you can't make zealots question the perfection of their belief systems.

  Business inaction could lead to data privacy laws
  2nd, May, 2005

U.S. businesses for years have urged the government to let them set computer-security standards of their own, but their inability to do so could now prompt Congress to step in, experts say.

  Spying on the spyware makers
  5th, May, 2005

The 25-year-old researcher has spent years analyzing how spyware and adware programs work and publicizing his findings.
