(This will come as no surprise to those who recall the definition of training as the modification of attitudes and behaviour.) He also notes that security professionals frequently concentrate solely on presentation of problems. The remainder of the introduction looks at other major security activities, and the part that awareness plays in ensuring that they actually work. http://www.linuxsecurity.com/content/view/128459/171/ --- Robert Slade Review: "Information Security and Employee Behaviour" The best way to secure you against sniffing is to use encryption. While this won't prevent a sniffer from functioning, it will ensure that what a sniffer reads is pure junk. http://www.linuxsecurity.com/content/view/128404/171/ -------- --> Take advantage of the LinuxSecurity.com Quick Reference Card! --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf +---------------------------------+ | Distribution: Debian | ----------------------------// +---------------------------------+ * Debian: New iceweasel packages fix several vulnerabilities 3rd, August, 2007 Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser.
