Schneier's latest Crypto-Gram is out, with the results of a provocative study:
A random computer on the Internet is scanned dozens of times a day. The life expectancy of a default installation of Red Hat 6.2 server, or the time before someone successfully hacks it, is less than 72 hours. A common home user setup, with Windows 98 and file sharing enabled, was hacked five times in four days. Systems are subjected to NetBIOS scans an average of 17 times a day. And the fastest time for a server being hacked: 15 minutes after plugging it into the network.
