Wireless networks, specifically IEEE 802.11, are inexpensive and easy to deploy, but their signals can be detected by eavesdroppers at great distances. Even with existing and new security measures, wireless networks have a higher risk than wired nets. WIDS, Wireless Intrusion Detection System, provides an additional layer of security by combining intrusion detection with physical location determination, using directional antennas. We briefly describe WIDS and present our initial results of remote station location using inexpensive hardware.
63ifteen years ago, servers for university computer science departments used disks with 2GB capacity; indeed, 1MB floppy disks were still useful. Many computers were connected to the Internet, many of them malicious, many at low, dial-up speeds of 9.6Kbps. But, thanks to Moore's Law, that scale of operation is now considered meager. Today's desktop computers commonly have 2GB of memory, and more than 100GB of disk space. A 10-person company can have over a terabyte of disk space on its desktop machines alone. Home computer users connect to the Internet with high-speed links of 3-6Mbps, rivaling the bandwidth of smaller CS department networks not long ago.
DIAGNOSING YOUR SYSTEM WITHOUT KILLING IT FIRSTF By FRANK ADELSTEIN Live Forensics:Live forensics gathers data from running systems, providing additional contextual information that is not available in a disk-only forensic analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
