ICS

ICS LabsWorld-class sponsored research on all aspects

of cyber security in collaboration with leading academic, industry and government partners

ICS IncubatorDevelops innovative security products and companies by

bringing in novel and commercially viable ideas and prototypes,

incubating and developing these and spinning out companies

ICS CIASConducts dark screen

exercises and training at the city and county level to

improve our nation’s capability to withstand coordinated cyber

attacks

We are a startupFounded June 2007 by multi-million start-up funding from State of Texas, conditional on recruiting Prof. Ravi Sandhu to lead ICS We are different

World-class research with commercialization

ICS Labs is off to a great start$1.7M (UTSA portion) in new funding won in 2008 in partnership withPurdue, UIUC, UMBC, UNCC, Michigan, UTD, Penn St., ASU, Georgia Tech

Theorye.g., P =? NP,

Automata

Implementatione.g., Virtualization,

Peer-to-peer

Modelse.g., 7-layer OSI nw stack,

OO Programming

A good PhD dissertation should involve all 3 elements but contributions will typically emphasize one of these

INSTITUTE FOR CYBER SECURITY Current Funded Projects Managing the Assured Information Sharing Life Cycle (AISL)

Sponsor: Air Force Office of Scientific Research, MURI, 2008-2013Partners: UMBC, Michigan, UIUC, Purdue, UTD 9/11 caused us to move from a "need to know" mindset to a "need to share" posture. What

does this really mean? What are the implications? How can we share safely? How do we “share but protect”?

Securing Dynamic Online Social Networks Sponsor: National Science Foundation, 2008-2012 Partners: Penn. State Univ., ASU, UNC-Charlotte Content, often including private sensitive data, is flowing into social networks at a very high

rate. How do we enable privacy and security without impacting the velocity of data transfer and

convenience?

A Framework for Combating Stealthy BotnetsSponsor: Air Force Office of Scientific Research, MURI, 2008-2013Partners: Georgia Tech. Botnets are the most dangerous, widespread and insidious attack vehicles on the Internet.

Future botnets are anticipated to use stealth techniques such as encryption and aggregation to avoid exposure, easily defeating current detection techniques. What do we do to contain this threat?

Secure Knowledge Management: Models and Mechanisms Sponsor: National Science Foundation, 2007-2009 How do we combine cryptographic techniques and access control techniques to effectively

protect information and knowledge?

INSTITUTE FOR CYBER SECURITY Conclusion

The need for cyber security will only grow Unless humans suddenly transform into angels Unless cyber innovations stop delivering productivity gains

The best we can offer is to stay ahead of the attackers Attackers are often more innovative and more incented than defenders Every cyber technology innovation creates a new attack-defend cycle No final solution

UTSA has a world class research operation in cyber security Take security courses Join our team Come talk to me: drop me an email and I will make

time We have multiple openings

Come join us on Nov 18th to celebrate our Founders Day 4:00-5:30pm: Distinguished lecture by Prof. Eugene Spafford of

Purdue 5:30-7:00pm: Wine and cheese reception See www.ics.utsa.edu
