If you think you have a sound IT policy because your administrators clamor about the continual need to update security patches, you might want to think again. One way to answer all these crucial questions and gauge true security preparedness is to undertake an IT security policy audit. . .
Whether or not you've deployed wireless networks, they're a threat. Fight back with these eight steps. Take one look at the tangle of cables connecting the computer to its monitor, peripherals and printers, and it's not hard to imagine how someone thought "wireless." Sample the wireless 802.11b network (a.k.a. Wi-Fi and AirPort) in a café after crawling around on your hands and knees underneath your desk trying to find a live Ethernet port.. . .
The IP Security Protocol (IPsec) and the Internet Key Exchange (IKE) protocol are designed to permit system and network administrators the capability to protect traffic between two systems. These systems can be network devices or individual hosts. With the release of . . .
Service providers have various options in the way in which they can offer outsourced IP virtual private network (VPN) services to customers. The original service offerings were mostly customer premises equipment (CPE)-based. In such services, service providers deploy and manage . . .
This paper describes the fundamental components of infrastructure design, provides an overview of risk management concepts, and illustrates samples of network topologies. . . .
Jason Coombs from forensics.org raises the "bad data" issue present in the way DNS works, and requests support to develop a solution. "With respect to DNS, and its eventual successor DNSSEC, it can no longer be tolerated by Internet users that the DNS makes no attempt to restrict the spread of "bad data".
