Keynote Speakers

Neal Ziring

IA Technical Director U.S. National Security Agency (NSA)

Title: Cyber Threat and Defense Trends

Bio: Mr. Neal Ziring is currently a technical director in the Information Assurance Directorate (IAD), at NSA. The IAD provides cryptographic, network, and operational security products and services to protect and defend national security systems. Prior to his role at the IAD level, Neal was a technical director for the Vulnerability Analysis and Operations Group, which provides technology evaluations, defensive operations, and secure configuration guidance for the DoD and the IC. During that time, Neal also served as security architect for two major NSA mission systems programs, collaborated with NIST on the Security Content Automation Protocol (S-CAP) specifications, and lead analysis efforts for Cloud Computing technology and IPv6. Neal has degrees in Computer Science and Electrical Engineering from Washington University. Before coming to NSA in 1989, he worked at AT&T Bell Labs.

Richard Stiennon

Chief Research Analyst IT-Harvest

Title: Post Apocalyptic Cyber Realism

Abstract: Predictions of impending cyber doom have become the clarion call of pundits, book authors, and defense contractors. They exhort their audiences to spend more, make changes, and prepare for cybergeddon. Richard Stiennon, industry analyst, and author of Surviving Cyberwar presents a different perspective. He looks at the recent history of cyber intrusions and demonstrates that disaster has already befallen us. The executive branches of government of each Western country have already been infiltrated. The military centers of the US, UK, Germany, and India, have already been compromised. Carefully orchestrated cyber riots have been encouraged to attempt regime change in Estonia and Georgia. The technology, mineral resources, and defense industrial bases have been seriously compromised. Those that look to the sky and predict its fall should take care not to stumble on the shards of that sky under their feet.

CERIAS Security Seminar Session

Carter Bullard, CEO/President

QoSient, LLC

Title: Society, Law Enforcement and the Internet: Models for Give and Take

Abstract: The interaction of society, law enforcement and telecommunications has evolved over the last 140 years to a successful balance of give and take. Society gives, providing well-defined processes and procedures that allow the government, law enforcement and citizens regulated access to information routinely collected by telecommunications service providers. And society benefits, where its justice systems can effectively use the information in support of criminal investigations and civil dispute resolutions.

Internet technology has been designed, developed and deployed without any consideration to this relationship, and the technical and social void that has emerged is actively being exploited, reducing the security of the Internet, and the natural compensatory actions threaten innovation and privacy.

The presentation discusses how a comprehensive policy regarding Internet communications identifying information (CII), could align the Internet with the existing public private partnerships that have evolved, minimizing the threats to privacy that an Internet ‘wiretapping’ strategy alone could generate.

Bio: Carter Bullard is a pioneer and industry expert, holding both academic and industry positions researching computer network security. In the early 1990’s, he established research programs in network vulnerability analysis and assessment at Carnegie Mellon’s CERT, where he pioneered and developed the concepts of network flow based forensics, and situational awareness. Carter helped develop and standardize the complete security architecture for ATM networking while a principal at FORE Systems and Nortel Networks, and most recently has been conducting security research in the areas of high performance virtual networking, forensics, optimization, awareness, and protection, at the U.S. DoD. He has authored over 20 contributions to the IETF, ITU, and the ATM Forum in the areas of network security, has consulted to U.S. Federal and State agencies regarding large scale network surveillance, mitigation, attribution and protection.
