Two tools which have become the norm in Linux- and Unix-based environments are SSH for secure communications, and sudo for performing administrative tasks. These are independent programs with substantially different purposes, but they are often used in conjunction. In this talk, I describe a flaw in their interaction, and then present our solution called public-key sudo.
Public-key sudo is an extension to the sudo authentication mechanism which allows for public key authentication using the SSH public key framework. I describe our implementation of a generic SSH authentication module and the sudo modifications required to use this module.

He received his B.A and M.Eng from MIT in 2000, and 2002, respectively. His research interests are in network anonymity, trust management, and enterprise-scale policy enforcement.
Configuration Management with Cfengine
Cfengine is a policy-based configuration management system. Its primary function is to provide automated configuration and maintenance of computers, from a policy specification.
The cfengine project was started in 1993 as a reaction to the complexity and non-portability of shell scripting for Unix configuration management, and continues today. The aim was to absorb frequently used coding paradigms into a declarative, domain-specific language that would offer self-documenting configuration.
about the speaker: Steven Kreuzer has been working with Open Source technologies since as long as he can remember, starting out with a 486 salvaged from a dumpster behind his neighborhood computer store. In his spare time he enjoys doing things with technology that have absolutely no redeeming social value.
