Matthew Burnside on Public Key sudo (MP3)

This is a talk (MP3) about sudo and ssh by Matthew Burnside (New York BSD User Group – NYC*BUB)

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.
