Concepts and techniques from mathematics--specifically, from lattice theory and reflexive theory--have already been applied to counterterrorism and computer security problems. The following is a partial list of such problems:

1. Strategies for disrupting terrorist cells
2. Data analysis of terrorist activity
3. Border penetration and security
4. Terrorist cell formation
5. Information security

This article proposes the creation of a European Institute for Mathematical Methods in Counterterrorism (IMMC), to be based in Austria. Such an institute would require minimal investment but could serve as a catalyst to draw several million euros in research grants and contracts to Austria. This influx of funding would benefit not merely scientists and firms working in homeland security, but other aspects of Austrian science as well.
