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...
متن کاملSimplifying 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...
متن کاملModel of Narrative Nowness for Neurocinematic Experiments
Cognitive neurosciences have made significant progress in learning about brain activity in situated cognition, thanks to adopting stimuli that simulate immersion in naturalistic conditions instead of isolated artificial stimuli. In particular, the use of films in neuroscientific experiments, a paradigm often referred to as neurocinematics, has contributed to this success. The use of cinematic s...
متن کاملLockdown: A Safe and Practical Environment for Security Applications
We describe, build, and evaluate Lockdown, a system that significantly increases the level of security for online transactions, even on a platform infested with malicious code. Lockdown provides the user with a highly-protected, yet also highly-constrained trusted environment for performing online transactions, as well as a high-performance, general-purpose environment for all other (non-securi...
متن کاملThe nature of ferroelectricity under pressure
Advances in first-principles computational approaches have, over the past fifteen years, made possible the investigation of physical properties of ferroelectric systems. In particular, such approaches have led to a microscopic understanding of the occurrence of ferroelectricity in perovskite oxides at ambient pressure. In this paper, we report ab-initio studies on the effect of hydrostatic pres...
