IT Pro Briefing: How To Secure Desktop PCs With Personal Firewalls
The top performer of the latest round of tests is the Jetico personal firewall, one that seems to stop just about anything, at least according to Firewall Leak Tester's results.UM Study: Hackers Attack Computers Every 39 Seconds
Personal firewalls aren't a luxury anymore. As more users roam with their laptops in and out of corporate networks, it's easy for their devices to become infected. This has prompted companies to look for ways to shield them from the continual attacks raging across the Internet.
Yes, continual attacks. A recent study from the University of Maryland Clark School's Center for Risk and Reliability and Institute for Systems Research finds that attackers attempted to breach the average Internet-connected computer every 39 seconds. "Our data provide quantifiable evidence that attacks are happening all the time to computers with Internet connections," says Michel Cukier, the author of the study and an engineering professor at the school. The computers in Cukier's study were attacked, on average, 2,244 times a day.
Cukier and two of his graduate students, Daniel Ramsbrock and Robin Berthier, set up weak security on four Linux computers with Internet access, then recorded what happened as the individual machines were attacked. They discovered the vast majority of attacks came from relatively unsophisticated hackers using "dictionary scripts," a type of software that runs through lists of common usernames and passwords attempting to break into a computer.Jetico Firewall (stable, beta)
