Dependability of Safety-Critical Computer Systems through Component-Based Evolution

-The article is an extension of this paper 1 . It describes methods for dealing with reliability and fault tolerance issues in cloud-based datacenters. These methods mainly focus on the elimination of a single point of failure within any component of the cloud infrastructure, availability of infrastructure and accessibility of cloud services. Methods for providing the availability of hardware, software and network components are also presented. The analysis of the actual accessibility of cloud services and the mapping of a cloud-based datacenter infrastructure with different levels of reliability to the Tier Classification System 2 is described. Non-compliance of the actual accessibility with the level of High Availability for cloud web services is unraveled.

“…Moreover, the dependability of a computer system is a property that equates to its trustworthiness. The dependability attributes in CBSD has been considered in many studies (De Andrés et al, 2008;Gallina et al, 2012;Kharchenko et al, 2009;Tambe et al, 2010;Yi and Li, 2011). Dependability counters the security vulnerabilities, abnormal behavior and untrustworthy issues in a software system.…”

Existing software applications become increasingly distributed as their continuity and lifetimes are lengthened; consequently, the users' dependence on these applications is increased. The security of these applications has become a primary concern in their design, construction and evolution. Thus, these applications give rise to major concerns on the capability of the current development approach to develop secure systems. Component-Based Software Development (CBSD) is a software engineering approach. CBSD has been successfully applied in many domains. However, the CBSD capability to develop secure software applications is lacking to date. This study is an extension of the previous study on the challenges of the security features in CBSD models. Therefore, this study proposes a solution to the lack of security in CBSD models by highlighting the attributes that must be embedded into the CBSD process. A thorough analysis of existing studies is conducted to investigate the related software security attributes. The outcome analysis is beneficial for industries, such as software development companies, as well as for academic institutions. The analysis also serves as a baseline reference for companies that develop component-based software.
