Web browsers use GPUs to render graphics on desktops, laptops, and smart phones. GPUs are also used to accelerate applications on the cloud and data centers. GPUs are usually programmed using application programming interfaces, or APIs, such as OpenGL. OpenGL is accessible by any application on a desktop with user-level privileges. Since desktop or laptop machines by default come with the graphics libraries and drivers installed, the attack can be implemented easily using graphics APIs.

A new technique protects power grids from attacks against utility control systems that can shut down facility operations, trigger longer-term blackouts and even cause permanent physical damage.

The criticality of certain sectors, as well as the requirement of users, involve Cloud providers to guarantee a high level of performance. This article embraces two parts, including a first section that assesses the factors which influence performance by using an analysis methodology inspired by the concept of the Taguchi experience plan. The second part builds on the conclusions of the first section by proposing a three-level architecture that optimizes load balancing via an ACO algorithm.

Cyber-security researchers have identified a total of at least 57 different ways in which cyber-attacks can have a negative impact on individuals, businesses and even nations, ranging from threats to life, causing depression, regulatory fines or disrupting daily activities

At a time when demand for cybersecurity expertise has never been higher, Carnegie Mellon University has just been awarded a $5 million renewal of its National Science Foundation CyberCorps Scholarship for Service program through 2023. Led by Dr. Dena Haritos Tsamitis, the Barbara Lazarus Professor in Information Networking and director of Information Networking Institute, the SFS@CMU program provides students a full-tuition scholarship and a generous stipend in exchange for government service in a cybersecurity role.

Researchers from MIT have developed a new security system that has been shown to outperform Intel's own approach at preventing so-called 'timing attacks' made possible by vulnerabilities like Meltdown and Spectre.
