We asked 7 experts 7 questions to find out what has occurred recently in terms of applying formal methods (FM) to security-centric, cyber problems.

Given daily press announcements concerning new malware, data breaches, and privacy...

This paper describes a classification for detecting hacked Twitter accounts. The model is mainly based on features associated with behavioural change such as changes in language, source, URLs, retweets, frequency an...

Male putty-nosed monkeys have two main alarm calls, pyows and hacks. While pyows have a broad distribution suggestive of a general call, hacks are often indicative of eagles. In a series of articles, Arnold and Zuberbühler showed that putty-nosed monkeys sometimes produce distinct pyow-hack sequences made of a small number of pyows followed by a small number of hacks; and that these are predict...

In recent years, wireless networks have become increasingly common and an increasing number of devices are communicating with each other over lossy links. Unfortunately, TCP performs poorly over lossy links as it is unable to differentiate the loss due to packet corruption from that due to congestion. In this paper, we present an extension to TCP which enables TCP to distinguish packet corrupti...
