The SANS Internet Storm Center's Handler's Diary provides a wonderful source of up-to-date information on current Internet security threats. Today, for example, it is reminding people that Microsoft will be auto-updating Windows XP machines to Service Pack 2 tomorrow, even if users have previously opted-out of the patch. It also includes a list of ports and IP addresses that might indicate your system is being used as a spambot. The diary is aimed at information security managers, information technologists and power users. If you are in these select groups, consider setting your browser's home page to the latest Handler's Diary page to keep up with current events.
