Tutorial #1: Network Security Protocol Standards

This tutorial is an advanced course, a logical successor to the introductory material presented by the instructor at NDSS '98 , '99 and '00.

In this tutorial, the instructor analyzes security issues in the Internet environment, via examination of cryptographic-based, standard security protocols. The tutorial begins with a very brief review of network security concerns, terminology, and an analysis of security protocol layering issues. It then examines public-key certificate management technology standards (specifically X.509 v3). Three major IETF security protocols are examined in detail: IPsec, SSL (TLS), and S/MIME.

Tutorial #2: Network Security Protocols: Generic tricks and emerging standards

Who are you, and should you be doing that? These are the basic questions that a system connected to a network should be pondering. Network security protocols help to answer these in a secure way. This tutorial gives an overview of how such protocols work, including the basics of cryptography, key distribution, and protocol design pitfalls. Although there are plenty of standards in terms of cryptographic algorithms, certificate formats, and protocols, there are still open problems about how to make a system that will truly scale to the Internet, and allow mutually distrustful organizations to interoperate. This tutorial emphasizes the challenges as well as the well-known technology. Once the generic issues are covered, the tutorial gives an overview and analysis of deployed and emerging standards such as Kerberos, X.509/PKIX, IPSec, and SSL.

Tutorial #3: Building Secure Software: Why the standard approach to security doesn't work

These days, computer security is a hot topic. As businesses rush towards the e-commerce cliff like so many lemmings, security stops being a minor detail and starts to carry some serious weight. So it's no big surprise that security seems to be all over the place these days. Of course, since many technically-savvy people don't know very much about security, a majority of the hubbub devoted to computer security orbits around basic technology issues such as what firewalls are, when to use the DES encryption algorithm, which anti-virus product is best, or how the latest email-based attack works. The problem is, many security practitioners don't know what the problem is! Firewalls and cryptography are important, but they're not a complete solution to security. Deploying insecure systems that include both firewalls and cryptography is unfortunately common.

What lies at the core of most security problems, then? It's the software. You can have the world's best firewall, but if you let people access applications through your firewall and the software is exploitable over the network, then the firewall is irrelevant. Cryptography is rarely the weak link in a system that an attacker will try to break either. Finding security problems in the surrounding software is often much easier. Internet-enabled software applications, including those developed in-house, present the most important category of security risk encountered today, and are the target of choice for real attackers.

This tutorial is all about software security risk and how to manage it. The trick is to begin early, know your threats, design for security, and subject your design to thorough objective risk analyses and testing. My goal is to provide tips and techniques that architects, developers, and managers can use to produce Internet-based code that is as secure as possible.

Tutorial #5: Biometrics

"Biometric" identification refers to the automatic identification or identity verification of living human individuals based on behavioral and physiological characteristics. The modern science of human identification dates back to the 1880's, but it has only been in the last 50 years that "automatic" identification has been possible. Automatic speaker recognition has the oldest history, but automatic fingerprint and hand identification were not far behind. In the last 10 years, the scientific community has begun to understand biometric identification as a unified area of inquiry, but no textbook or dedicated journal yet exists in the field. A basic undergraduate understanding of mathematics, probability and statistics is assumed. A background in digital signal processing will be helpful, but not required.

In this short course, we will:

  1. review the history of biometric identification and the primary literature in the field;
  2. discuss several major applications;
  3. present an overview of face, fingerprint, voice, and iris recognition algorithms;
  4. establish a methodology for comparison of biometric devices and > applications;
  5. explain common testing measures and approaches;
  6. present results of scientific tests conducted over the past decade;
  7. present existing standards for performance and performance assessment;

Date/Time: 7 February 2001, am session

Tutorial #6: Secure Electronic Commerce Tutorial

Electronic commerce is flurishing, but security remains a critical concern, even an inhibitor for some potential businesses. This tutorial will present the major problems and solutions for secure e-commerce; our goal is that participants will gain the ability to invent, design and evaluate innovative secure e-commerce solutions. The focus on the tutorial will be on secure payments, an important and interesting area in which the tutor have made considerable contributions over the last eight years. We will also cover the important areas of business to business e-commerce, public key infrastructure and trust management for e-commerce, and security for mobile commerce.

Tutorial #7: Group Security

Multicast communications and group interactions are fast becoming critical Internet technologies. The ranges of business services that can benefit include; broadcast media delivery, interactive simulations, teleconferencing, IP Telephony, and collaborative applications. The security technologies for groups are not well served by current standard security protocols. Group security has been a research effort and has produced viable technologies to address the problems. This tutorial program will cover recent advances in multicast security. The program will include discussion of group security policy, group key management, group rekey (Logical Key Hierarchies and One-way Function Trees), and multicast source authentication.
