due to vulnerabilities in the TCP-IP protocol‚ and no global flow control mechanisms. The two problems lead to many TCP exploits and the horrible DDoS attacks. We have devised a method of incrementally upgrading the network infrastructure at the transport level that solves the above problems and makes the network significantly more resilient to attacks‚ particularly the DDoS attack. The approach uses "hardened routers"‚ routers that can do simple cryptographic functions (encryption‚ signatures) on

Besides the basic physical security of a site‚ the next most important aspect is controlling digital access into and out of the organization’s network. In most cases this means controlling the points of connectivity to the outside world‚ typically the Internet.

The Science of Transportation: Ancient World: The Wheel: • How do they work? Wheels work by rolling along a surface. The curved surface of the wheel reduces the friction between the two surfaces due to a decrease in surface area. With less friction it is much easier to move an object. This is because rolling friction is much weaker than sliding friction. • How did they come to be? The wheel was invented in prehistoric times; as the oldest example of a wheel yet found is from the region of
