Marcus Ranum, President and CEO of Network Flight Recorder, Inc.
How to REALLY secure the Internet.

Is it possible to really secure the Internet? With current technology and methods, the answer would appear to be a resounding "no." We've tried security through stepwise refinement and security through consensus - the best remaining solutions are totalitarian and draconian.  Marcus will present an outline for how the Internet could be secured through some simple, cost effective methods. He'll also explain why it won't happen.

Marcus Ranum is CEO of Network Flight Recorder, Inc., and has been specializing in Internet security since he built the first commercial firewall product in 1989. He has acted as chief architect and implementor of several other notable security systems including the TIS firewall toolkit, TIS Gauntlet firewall, whitehouse.gov, and the Network Flight Recorder. Marcus frequently lectures on Internet security issues, and is co-author of the "Web Site Security Sourcebook" with Avi Rubin and Dan Geer, published by John Wiley and sons.


Bruce Schneier, President of Counterpane Systems and author of Applied Cryptography.
Mistakes and Blunders: A Hacker Looks at Cryptography.

From encryption to digital signatures to electronic commerce to secure voting cryptography has become the enabling technology that allows us to take existing business and social constructs and move them to computer networks.  But a lot of cryptography is bad, and the problem with bad cryptography is that it looks just like good cryptography; most people cannot tell the difference.  Security is a chain: only as strong as the weakest link.  In this talk I'll examine some of the common mistakes companies make implementing cryptography, and give tips on how to avoid them. 

Bruce Schneier is president of Counterpane Systems, the author of Applied Cryptography, and the inventor the Blowfish algorithm.  He serves on the board of the International Association for Cryptologic Research and the Electronic Privacy Information Center.  He is a contributing editor to Dr. Dobb's Journal, and a frequent writer and lecturer on cryptography.


Theo DeRaadt, Lead developer of OpenBSD.
Secure coding, problems with maintain source trees, and secure design philosophies.

Theo de Raadt heads the OpenBSD project.  This 4.4BSD derived operating system project has increasingly placed it's focus on discovery and repair of security issues.  Due to a 2 year auditing process by a 10 member team, OpenBSD is probably the most secure operating system in common use today.  For more information, see http://www.OpenBSD.org/security.html



 
Ira Winkler, President of the Information Security Advisory Group.
Information Security: Beyond the Hype

If you read the headlines today, you would think that no matter what people are doing to secure themselves, they will never be secure.  The reason that the concept comes across is that the media focuses on the Threats and stories about unstoppable geniuses that can compromise even the Pentagon. The truth is that you can protect yourself from even the most diabolical genius.  This presentation discusses Information Security from a Risk based perspective.  The threats to your systems are discussed, but more important the vulnerabilities that actually allow the threats to compromise your systems are discussed.  Using that information, you can then choose the countermeasures you need to protect yourself and your organization.  This presentation will show you that while there is no such thing as perfect security, you can protect yourself from almost all of the most serious threats.  Probably what is most valuable to attendees is guidance on how to spend limited funding in the most efficient manner.

Ira Winkler, CISSP is considered one of the world's leading experts on Information Security, Information Warfare, investigating information related crimes, and Industrial Espionage.  He is author of the book, Corporate Espionage, and President of the Information Security Advisors Group.  His clients include some of the largest companies and banks in the world.  He is also a columnist for ZDTV with his column titled Spy Files.  He also functions as the networks security expert.  Previously, Mr. Winkler was with the National Security Agency and was the Director of Technology with the National Computer Security Association.  He has also performed studies on Information Warfare for the Joint Chiefs of Staff.

Their Presentation! (PowerPoint 81k)


Dominique Brezinski, Network Security Professional Secure Computing Corporation.
Penetrating NT Networks Through Information Leaks and Policy Weaknesses.

The focus of this presentation will be a demonstration of how Windows NT hosts can be queried for information and how the information can be correlated to provide an attacker with a path of least resistance. Even though many Windows NT networks have few remotely exploitable technical vulnerabilities (buffer over-runs, flawed CGI scripts, address based authentication etc.), most NT networks give away too much information. By analyzing the information it is easy to find policy weaknesses that can be exploited to gain access to the NT hosts. Custom tools will be demonstrated on a small network.

Dominique Brezinski is a Network Security Professional at Secure Computing Corporation and has been concentrating on Windows NT and TCP/IP network security issues for four years. Prior to working for Secure Computing, Mr. Brezinski worked as a Research Engineer at Internet Security Systems where he was responsible for finding new vulnerabilities and security assessment techniques for Windows NT.  In 1996 Mr. Brezinski published a white paper entitled "A Weakness in CIFS Authentication" which revealed a serious flaw in the authentication protocol used in Windows NT (NT LM Security). It was shown for the first time that an attacker could completely subvert the network authentication in Windows NT to gain unauthorized access to Windows NT servers. Mr. Brezinski has continued to demonstrate advanced techniques for assessing the risks present in Windows NT networks. 


Richard Thieme, Thiemeworks, Inc.
Convergence -- Every Man (and Woman) a Spy.

Arbitrary digital interfaces - television, PCs, PDAs - are converging, but that's only part of the story. The roles people play in work and life are converging too. Intelligence agents, knowledge managers for global corporations, competitive business intelligence agents, sysadmins, hackers,  journalists, and CIOs are becoming indistinguishable. Why does that matter? Because the ability to synthesize and integrate information, manage complexity and ambiguity, morph continually into roles appropriate to a shifting work context, and somehow remember who you are - that's what matters most. Our presentations of ourselves are the powerful levers that move mountains in the digital world. Richard Thieme discusses why and how to do it. 

Richard Thieme is a business consultant, writer, and professional speaker focused on the human dimension of technology and the work place. His creative use of the Internet to reach global markets has earned accolades around the world.  "Thieme knows whereof he speaks," wrote the Honolulu Advertiser. He is "a prominent American techno-philosopher" according to LAN Magazine (Australia), "a keen observer of hacker attitudes and behaviors" according to Le Monde (Paris), "one of the most creative minds of the digital generation" according to the editors of Digital Delirium, and "an online pundit of hacker culture" according to the L A Times.

Thieme's articles are published around the world and translated into German, Chinese, Japanese and Indonesian. His weekly column, "Islands in the Clickstream," is published by the Business Times of Singapore, Convergence (Toronto), and South Africa Computer Magazine as well as distributed to subscribers in 52 countries.  Recent clients include:  Arthur Andersen; Strong Capital Management; System Planning Corporation; UOP; Wisconsin Power and Light; Firstar Bank; Northwestern Mutual Life Insurance Co.; W. H. Brady Company; Allstate Insurance; Intelligent Marketing; and the FBI.


Ian Goldberg -ISAAC Research Group, UC Berkeley.
Cell phone security: a history and the state of the art.

Cellular phones are a growing convenience for many people of many walks of life.  Recently, ads for new "digital" cell phones promise privacy and unclonability to their customers.  In this talk, we will examine these claims, looking at systems from the oldest analog phones to the modern digital standards.  Special attention will be paid to the security of the GSM system, the most popular digital cell phone standard in the world.

Ian Goldberg is a Graduate Student Researcher and founding member of the Internet Security, Applications, Authentication and Cryptography (ISAAC) research group at UC Berkeley.  His research areas include cryptography, security, privacy systems, and digital cash.  In April, he, along with colleagues David Wagner and Marc Briceno, announced the discovery of a major security flaw in most of the deployed GSM digital cell phones.


Ray Kaplan - 
Who are the enemies of computer and network security?

Generally, "hackers" are regarded as criminals by the "legitimate community."  Who are these "hackers" that seem to keep whacking on our systems and networks? Are they merely scumbag reprobates that should be purged from the society?  Is there anything to learn from them?  This session is intended to introduce the two sides of the security equation to one another in a forum which fosters open, detailed, honest communication.  Bring your questions.

  What techniques do they employ against us?  Are those that attack our  systems all just a bunch of slime balls that are devoid of morals,  ethics, and common sense?  While in the minority of reported  computer crime statistics, the skilled outsider still represents a  significant threat.

This session explores who they are, their attitudes, their techniques, their successes and their failures from the perspective of what we have to learn from them to better protect your systems and networks.  This classic session allows you to interact directly with members of the computer underground.   Join us for some stimulating conversation with those who computer security professionals consider to be their enemies.

Mr. Kaplan has been actively involved with system and network security as a consultant for over half of his more than 20 years in the industry. There is no question that he hacks.  However, he is not a criminal.  His clients have included the world's largest financial institution, smallest commodities broker and a wide variety of organizations, including multinational and Fortune 100 companies from all segments of the economy, and public institutions all over the world. 

Mr. Kaplan is a very prolific lecturer, instructor and writer.  He consults, lectures and teaches technical system and network related topics all over the world.  His articles are frequently published in major computer journals and magazines.  In over ten years of public speaking and audio/video conference production, he has given over 2,000 technical, tutorial style presentations and lectures in forums such as professional societies, seminars and his consulting.  As a frustrated inventor, he is forever trying to rid the world of inefficiency, frustration and waste by pursuing new paradigms in the delivery of training, education and technical information.

Thomas Ptacek, Network Security Professional at Network Associates, Inc. (Formerly SNI
Defeating Network Intrusion Detection.

Network intrusion detection (ID), a technology that attempts to identify attackers by monitoring network traffic, is fast becoming one of the hottest products in the security market. Beneath the hype, however, lie some serious concerns about the reliability of currently available ID systems, as well as the fundamental techniques they use to collect information. This talk will explain why the most popular ID systems on the market can't be trusted, demonstrate how to avoid detection by them, and, in the process, eliminate some very widespread misunderstandings about the capabilities of sniffers and intrusion detection systems. 

Thomas Ptacek is a developer at Secure Networks, Inc. His work focuses on vulnerability assessment, which involves researching and testing network systems for exploitable design and implementation flaws. In the course of this work, his team has discovered some of the Internet's most serious security problems, including vulnerabilities in Windows NT, Checkpoint Firewall-1, and Solaris, as well as core Internet software such as the BIND, INN, and Apache.

Bruce K. Marshall, CISSP at Feist Communications.
Statistical analysis of reusable passwords and recommendations.

Bruce will present his study which is focused on analyzing the passwords of 3,163 users of a corporate computer network.  Since he actually has the plain text passwords of the users from a project Feist initiated, he was able to pump them into a database and then mine for information and correlations.  Robert Morris Sr. & Ken Thompson did a similar analysis (although their details aren't nearly as comprehensive) in 1979 and he will use that to show some time / trend progressions.  He doesn't think it will shock any of us who have dealt with security and know reusable passwords are insecure, but it will provide hard figures and new analysis.

Bruce K. Marshall, Information Security Specialist for Feist Communications Inc.  He has studied identification and authentication systems for several years to gain insight into their inherent strengths and flaws.  While the world grows increasingly computer based, he has fought to enforce acceptable means of securing these systems.  As a member of the Biometric Consortium and other security groups, Bruce has been exposed to a wide variety of alternatives to standard authentication methods.

When he's not removing sticky notes on monitors, Bruce Marshall multitasks his attention between business internetworking technologies, network operating systems and the related security for these areas.
