On February 16 at 9:20 a.m. PST, Noonan will deliver his keynote speech entitled, "Defending the self-defending network: Can computing be trustworthy in the 21st century?" Noonan will address his vision for the next generation of security and explain why it will take more than just technology to combat the ever-changing threat landscape.

Additional activities that ISS will conduct at the show include:

Booth # 1022 - New Products Expand Proventia Security Platform - ISS will announce four new solutions that offer organizations greater visibility, integrity and protection of their business-critical networks. The new solutions will play a key role in safeguarding customers' intellectual property, improving network efficiency and automatically detecting security threats and noncompliant activities that could compromise critical assets.

February 14 at 5:35 p.m. PST - Conference Session On Internal Network Security - ISS' Eric Hanselman will explore behavior and anomaly-based network security as an extension of gateway and host systems for safeguarding internal networks. The session, entitled "Advancing Internal Network Security: Beyond Perimeter & Host Protection," will address the value of network anomaly detection as a means to enforce security policy, improve asset management and prevent internal network abuse.

February 15 at 3:25 p.m. PST - Security Sector Roundtable - What's in store for the security sector? Thomas Noonan will join a panel of leading security sector CEOs to discuss topics including: the state of the security business, customer/market trends, product innovation and growth areas, managed security services, the evolving attack and threat model, new entrants into the sector and future potential industry consolidation.

Driving The Dialogue Around Vulnerability Research - 2005 was an active and sometimes controversial year in the field of vulnerability research. Debates arose regarding intellectual property rights and the practice of vendors paying bounties to people outside their own organization for vulnerability research. ISS' CTO Chris Rouland will be on hand to discuss current and future trends in vulnerability research and the role that the human element will play in the next generation of security.

Cyber Security/Public Policy Issues - ISS Director of Intelligence, Pete Allor, will be on site for an important meeting of the Information Technology - Information Sharing and Analysis Center (IT-ISAC) (https://www.it-isac.org). Allor, director of operations for the IT-ISAC, will be addressing the myriad cyber security and policy issues slated for discussion at the show. The success of the IT-ISAC has been driven in part by major structural changes announced at a previous RSA Conference that have ensured the long-term viability of the organization.
