Security risk assessment framework provides comprehensive structure for security risk analysis that would help uncover systems’ threats and vulnerabilities. While security risk assessment is an important step in the security risk management process, this paper will focus only on the security risk assessment framework. Viewing issues that exist in a current framework, we have developed a new framework for security risk and vulnerabilities assessment by adding new components to the processes of the existing framework. The proposed framework will further enhance the outcome of the risk assessment, and improve the effectiveness of the current framework. To demonstrate the efficiency the proposed framework, a network security simulation as well as filed tests of an existing network where conducted.

In software engineering, a software pattern is a reusable solution to solve recurring software design problems. Traditionally, suitable patterns are identified by software designers to satisfy a set of requirements. A part of appropriate patterns is then applied to a recurring software design problem. However, the existing software patterns part has to be properly integrated to specific design problems. Therefore, the introduction of formalization is required to describe this integration accurately. In this paper, we propose a framework of UML class diagrams and software patterns integration prepared for formal specification to solve different software designer's experiences. The integration rules in this formal framework is intended to complement existing textual and graphical descriptions in order to eliminate the ambiguity of class diagrams with software patterns integration. A case study of our approach is illustrated in a purchase order system.

In this paper, we propose a resource allocation and Tx power control scheme, called resource allocation and power control (RAPC) in an LTE-Advanced device-to-device (D2D) network. In the proposed scheme, the macro base station (mBS) and D2D senders (D2DSs) service macro user equipment (mUEs) and D2D receivers (D2DRs) use the different frequency bands and Tx power chosen as D2D links' locations in inner and outer zones to reduce interference substantially. We analyze and compare the proposed scheme and random resource allocation (RRA) scheme with fractional frequency reuse (FFR) systems in terms of the system throughput for DL and outage probability according to the number of D2D user's (D2DR) traffic density. Simulation results show that the RAPC scheme has better performance than the random resource allocation (RRA) scheme performance in terms of the system throughput and outage probability for mUEs and D2DRs.
