Meetings

sudo - secure and convenient

Mike Potter

Introduction to XML

Scott Nemec

Tuesday July 25th 2006 at 7:00pm
Wheaton, Illinois Institute of Technology - Rice Campus, Room 103

Abstract

The first half of the meeting will be about the 'sudo' administration utility. sudo is a security tool that comes pre-installed on many *NIX systems, including Mac OS X, and most distributions of Linux. sudo allows for fine grained control of privileges as an alternative to setuid programs & scripts, turning on read & write privileges on sensitive files, sharing passwords, and (gasp) giving out the root password. This presentation will begin with a quick demo for those of you who are unfamiliar with sudo, continue with an overview of the syntax of the configuration file, and end with a series of problems and solutions that will help you configure sudo to be secure and convenient.

The second half of the meeting will be an introduction to XML. The presentation will cover how an xml document is defined, along with several concepts like 'well-formed' and 'valid' (the modern definition of which uses an XML schema). Examples will be used in the presentation to help explain.
