The paper "The Role of a Security Consultant in the Architecture Design Process' is an outstanding example of a capstone project on architecture. The study empirically explored the roles of security professionals in the architecture design process. The objectives included determining how security professionals seek to ensure that threats and controls are in balance during the architecture design process. The study also aimed to integrate the systems approach in explaining the role of security professionals in the architecture design process and identifying the role of security professionals in ensuring the integrity of the security architecture. The study used a qualitative research design.
Primary data was collected through semi-structured qualitative interviews. Secondary data was collected through document analysis. Data analysis was through the qualitative interpretive method. The study summarised into three: To prevent overspending on unnecessary security devices, to prevent risks of liability due to failure to comply with regulatory requirements, and most lasting, to ensure that all the security layers or components serve their objective as required. These roles are fixed to the Defence in-depth theory and systems approach, as they make sure that the security architecture is designed to operate as part of the security system in order to holistically detect, delay, deter, and respond to security threats. Introduction The roles and responsibilities of security management professionals have expanded in scope since the 1990s parallel to the expansion of the private sector and the tendencies by firms to downsize, outsource, and adopt the technology (CISSP, 2012; Sennewald, 2012).
The rise in demand for security professional services has also been persistent since 9/11. While security consulting has grown, the roles of security professionals continue to remain unclear (Farah, 2004; Walek & Masar, 2013). Many organizations see a security professional be an individual tasked with recommending proper, cost-effective strategies to attain a wide range of security objectives, crime prevention, loss control, and investigative roles (Scholl et al, 2010).
This is, however, insufficient. Obviously, a rewarding dimension of security professionals is the opportunity to manage and control an organization’ s security (Tsohou et al. , 2015). The security professionals seek to ensure that threats and controls are in balance (Bogers et al. , 2008). Designing secure system architecture and its implementation and application are costly, time-consuming, and complex processes that demand expertise and intervention of a security professional, who is the expert for a particular problem domain.
A security professional selects the security features that can be integrated into a secure operating system (Vellani, 2009). The features selected that need to be implemented by security mechanisms have to see to it that the risks of disrupting the company asset’ s integrity, availability, and confidentiality are eliminated. Therefore, understanding the specific roles of a security professional is critical. In fact, as ISACA (2009) confirms, the exact role of security professionals is yet to be clearly defined in most enterprises. In some projects, the project team may proceed with defining the security requirement without the involvement of the security professional mostly due to a lack of understanding of the significance of security professionals (ISACA, 2009).
Their roles become more complicated when they are tasked with designing security architecture (Vellani, 2009). Security architecture is an integrated security design intended to handle the requirements and potential risks associated with a particular environment or scenario. The Security architecture details out when and where security controls should be applied (Tsohou et al. , 2015).
The process of designing the architecture is often reproducible and needs extreme expertise to ensure its effectiveness. This calls for the participation of a security consultant. As Gibbs (2008) mentions, in designing security architecture, the difference between hiring a security professional and ignoring it is on how holistically and effectively the security systems are expected to protect assets.
