In the first four months of 2014, two major vulnerabilities were announced affecting operation of the Transport Layer Security (TLS) protocol, which is used by applications to secure Internet communications. The ‘goto fail’ bug affected Apple’s iOS and OS X software and the ‘Heartbleed’ bug affected versions of the OpenSSL software. Whilst the Apple bug was serious because it affected a wide range...
Safety and security disciplines are often independent domains, with little interaction. There is increasing convergence driven by common technologies, platforms and networking, where safe operation of complex systems requires appropriate security. The two disciplines may also conflict, creating new hazardous that may require new safety functionality to reduce the security derived risk. Solely using...
The increasing use of communications and computer-based technologies within vehicles and the highways network, creates both risks and opportunities. This paper examines the need to adopt a security-minded approach to the use of these new technologies in order to reduce the likelihood of them being maliciously exploited, and impacting on the safety or security: highway systems; vehicles, vehicles occupants;...
Faced by serious challenges affecting competitiveness, sustainability and the safety and security of their inhabitants, cities’ authorities are investing in complex infrastructure projects to make more intelligent and efficient use of resources. Investments include improved asset management through greater use of building information modelling (BIM) and introduction of complex cyber–physical systems...
Given the increasing prevalence of cyber-physical systems in both the critical national infrastructure and in an emergent Internet of Things, our safety and security depends on their trustworthy operation. The combination of interconnectivity and the dynamic nature of many cyber-physical systems present new challenges if we are to reduce the risk of cascading or escalating failures. This paper examines...
The concept of an intelligent building has existed for over 30 years and is seen as a solution to a number of economic and environmental problems. Intelligent buildings are often seen as a means of improving the energy efficiency of the built environment. However they are increasingly being promoted as a means of improving the operational efficiency of buildings, providing enhanced building and personal...
