Implementing insider defenses

Insider Trading and Innovation

This paper assesses whether the enforcement of insider trading laws increases or decreases patent-based measures of technological innovation. Based on about 75,000 industry-countryyear observations across 94 economies from 1976 to 2006, we find evidence consistent with the view that enforcing insider trading laws spurs innovation—as measured by patent intensity, scope, impact, generality, and o...

Aspects of Insider Threats

The insider threat has received considerable attention, and is often cited as the most serious security problem. It is also considered the most difficult problem to deal with, because an “insider” has information and capabilities not known to external attackers. The difficulty in handling the insider threat is reasonable under those circumstances; if one cannot define a problem precisely, how c...

Defending Insider Threat

Network threat confronting organizations comes from not only outsider threat, but also insider threat. Nowadays, insider threat is widely recognized as an important issue of security management. However, tools and controls on how to fight against it are still in the research phase. Security architecture for defending insider threat is presented, which is composed of four parts: monitoring platf...

Adversarial Example Defenses: Ensembles of Weak Defenses are not Strong

Ongoing research has proposed several methods to defend neural networks against adversarial examples, many of which researchers have shown to be ineffective. We ask whether a strong defense can be created by combining multiple (possibly weak) defenses. To answer this question, we study three defenses that follow this approach. Two of these are recently proposed defenses that intentionally combi...
