Understanding Wireless Antennas
searchNetworking, March 6, 2003

Migrating To 802.11g

Vendors rushing to the "G party" include Actiontec (54 Mbps Wireless), Apple (AirPort Extreme), Buffalo (AirStation G54), D-Link (AirPlus Xtreme G), and Linksys (Wireless-G). Consumers struggling to choose between 802.11a and 802.11b now face another decision: whether and when to migrate to 802.11g.

The Sad And Increasingly Deplorable State Of Internet Security
Business Communications Review, February 2003

Internet security is, well, lame, and the situation may get worse before it gets better. Today, the vast majority of the security problems that plague us arise from three sources: insecure architectures, poor software engineering and sloppy management. Only by analyzing and committing ourselves to mitigate these root causes will we ever improve Internet security. Dave Piscitello and Steve Kent explore these issues in the February issue of BCR Magazine.
