Over the last decades, there were lots of studies made on malware and their countermeasures. The most recent reports emphasize that the invention of malicious software is rapidly increasing. Moreover, the intensive use of networks and Internet increases the ability of the spreading and the effectiveness of this kind of software. On the other hand, researchers and manufacturers making great efforts to produce anti-malware systems with effective detection methods for better protection on computers. In this paper, a detailed review has been conducted on the current situation of malware infection and the work done to improve anti-malware or malware detection systems. Thus, it provides an up-to-date comparative reference for developers of malware detection systems.

In the modern System on Chip (SoC)-based designs, embedded memory occupies the majority of the area. Therefore, the demand for fast self-testing plays a vital role in the SoC device as its memory density increases. The focus of this research study is to provide a self-testing mechanism integrated with the SoC design for fault diagnosis and failure analysis. In particular, this paper proposes a controller design to test memories at SoC devices, called a memory built-in self-test (MBIST) controller. This controller works on the principle of the proposed March-ee (enhanced elements) algorithm with the primary objective to improve the test speed, fault coverage, and power consumption at a low area overhead. The complete design of the MBIST controller with the associated March-ee algorithm is minimal and easy to be integrated into any SoC device to provide a vibrant feature of memory fault detection. The results obtained are compared with that provided by the existing March algorithms, using the same design specifications, where the proposed March-ee MBIST controller has shown better results in terms of power consumption, fault coverage, timing, and area.

Internet of Things (IoT) architecture, technologies, applications and security have been recently addressed by a number of researchers. Basically, IoT adds internet connectivity to a system of intelligent devices, machines, objects and/or people. Devices are allowed to automatically collect and transmit data over the Internet, which exposes them to serious attacks and threats. This paper provides an intensive review of IoT evolution with primary focusing on security issues together with the proposed countermeasures. Thus, it outlines the IoT security challenges as a future roadmap of research for new researchers in this domain.
