		UNIX SECURITY SYMPOSIUM PROGRAM

The goal of this symposium is to bring together security
practitioners, system administrators, system programmers, and anyone
with an interest in computer security as it relates to networks and 
the UNIX operating system.  The symposium will consist of a broad
range of topics including tutorials appropriate for a technial
audience, peer-reviewer technical presentations and panel sessions.
Attendees will have a unique opportunity to share their experiences
and ideas on UNIX system security.

TUTORIAL PROGRAM
Monday, September 14, 1992

Network Security: The Kerberos Approach
Dan Geer,Geer/Zolot Associates and Jon A. Rochlis, MIT

Intended Audience: Systems developers responsible for networked
workstation environments, particularly those whose environments may 
include networks which are not themselves physically secure (i.e.,
``open'' networks) and systems managers concerned about the inherent
lack of security for managing today's network-based environments
(e.g., UNIX's .rhosts files).

The amazing and constantly growing numbers of machines and users
ensures that untrustworthy individuals have full access to the Internet.
Given the increasing importance of the information transmitted, it is
imperative to consider the basic security issues present as large open
networks replace isolated timesharing systems.

This tutorial will focus on the challenges of providing security for
cooperative work arrangements consistent with the location and scale 
independence of today's open networking environment. Attendees will
gain an understanding of the kinds of security threats which result
from operating in an open environment, such as one composed of a
network of workstations and supporting servers. Effective approaches
to meeting these threats will be presented. Although emphasis will be
on the Kerberos system developed at MIT, public key techniques for
ensuring privacy and authentication on an open network will be explored.
The X.509 authentication model and the new Internet Privacy Enhanced
Electronic Mail RFC's will be discussed.

Internet System Administrator's Tutorial

Ed DeHart and Barb Fraser, Computer Emergency 
Response Team

Intended Audience: This tutorial is designed for users and system
administrators of UNIX systems. It is especially suited for system
administrators of UNIX systems connected to a wide area network based
on TCP/IP such as the Internet. Some system administrator experience is 
assumed.

The information presented in this tutorial is based on incidents
reported to the Computer Emergency Response Team. The topics covered 
include:

System administration - defensive strategies	
 	oPassword selection 
	 o Default login shell for unused accounts
 	o Network daemon configuration 
	 o Verification of system programs
 	o System configuration files
 	o Searching for hidden intruder files 
 o Staying current with software releases 
 o Standard accounting files
 	o NFS configuration

System administration - offensive strategies
 	o COPS 
	 o /bin/passwd replacement programs 
 	o TCP/IP packet filtering
 	o TCP/IP daemon wrapper programs
 	o Security in programming

Site-specific security policies 
	o Maintaining good security at your site
 	o Providing guidance to users
 	o Handling incidents in an effective
 				orderly fashion
 	o Reviewing Site Security Policy Hand
 	 	book (RFC 1244)

 Incident handling
 	o What to do if your site is broken into?
