Lockdown: Dynamic Control-Flow Integrity

Applications written in low-level languages without type or memory safety are especially prone to memory corruption. Attackers gain code execution capabilities through such applications despite all currently deployed defenses by exploiting memory corruption vulnerabilities. Control-Flow Integrity (CFI) is a promising defense mechanism that restricts open control-flow transfers to a static set o...

Simplifying Network Management with Lockdown

The administrator of an enterprise network has a responsibility to enforce the policies on the network. Yet, most security mechanisms do not map well to the intended policies. This has been due to the prevalence of simplistic tools that have poor enforcement but, yet are easy to manage. While advanced commercial solutions do exist that have stronger enforcement, they are significantly harder to...

Interactive Maths with GeoGebra

Paper brings information on dynamic multiplatform mathematical software GeoGebra produced by Markus Hohenwarter in 2002 for learning and teaching mathematics, available free on web in 45 languages. GeoGebra enables production of self-standing dynamic worksheets as interactive java applets embedded in html pages presenting dynamic constructions and interactive calculations on Internet Thus it is...

The maths of memory

Mathematical modeling reveals that long-term immunological memory is maintained in a manner that is even more dynamic than previously thought.
