Using Screend to Implement IP/TCP Security Policies
Abstract
True network security requires that all hosts attached to the network are themselves made secure, but network administrators often find it helpful to block certain kinds of packets at the routers. The screend program was designed to provide this function for routers based on the ULTRIX(Trademark) operating system. Although screend is a simple program, creating a screend configuration that does not compromise security can be a complex problem, requiring deep understanding of how IP/TCP networks are used and abused. This technical note provides some guidance.
