Security researchers show lightweight, host-based access-control scheme that dumps attack packets without overwhelming memory, CPU
Researchers have come up with host-based security software that blocks distributed denial-of-service attacks without swamping the memory and CPU of the host machines.The filtering, called identity-based privacy-protected access control (IPCAF), can also prevent session hijacking, dictionary attacks and man-in-the-middle attacks, say researchers at Auburn University in their paper, "Modeling and simulations for Identity-Based Privacy-Protected Access Control Filter (IPCAF) capability to resist massive denial of service attacks."
