Most software developers aren't primarily interested in security. For decades, the focus has been on implementing as much functionality as possible before the deadline, and patching the inevitable bugs when it's time for the next release or hot fix. However, the software engineering community is slowly beginning to realize that information security is also important for software whose primary function isn't related to security. Security features or mechanisms typically aren't prominent in such software's user interface.

The federated Cloud paradigm aims to provide flexible and reliable services composed of a mixture of internal and external mini-clouds, but this heterogeneous nature is also fuelling the security concerns of the customers. To allay the fears and deal with the threats associated with outsourcing data and applications to the Cloud, new methods for security assurance are urgently needed. This paper presents current work on Cloud Security Service Level Agreements and our approach on how to manage this in the context of hybrid clouds. The purpose is to facilitate rapid service composition and agreements based on the necessary security requirements and establish trust between the customer and provider. We also show how this can be applied on a realistic case study related to a hybrid Unified Communication service.

This article investigates and analyzes the security aspects of 5G specifications from the perspective of IoT‐based smart grids. As the smart grid requires high‐speed and reliable communication to enable real‐time grid monitoring via Internet of Things (IoT) devices, 5G can be considered a catalyst to transform the current power grid infrastructure into a smart grid. Thus, an understanding of what 5G can bring in terms of cyber security in IoT‐based smart grids is important for design decisions and future risk analysis efforts. In this article, we explore a smart grid use case on automatic voltage control—a use case utilizing 5G as a wireless communication infrastructure with edge support. We identify the benefits 5G brings to several security aspects, and show how 5G security techniques are applicable to the smart grid, thus providing a foundation for future security analysis of 5G enabled smart grid systems. Future research should extend this work to additional smart grid use cases.
