software architecture assessment methodology

For example, the good principle of "least privilege" prescribes that all software operations should be performed with the least possible privilege required to meet the need. How do you know if a software architecture is deficient or at risk relative to its target system qualities? Distributed processing 4. Software can also be vulnerable because of a flaw in the architecture. Through a series of interviews with business representatives, the initial information regarding assets should be discovered. 4. In the implementation phase, the identification of vulnerabilities should include more specific information, such as the planned security features described in the security design documentation. Application portfolio upgrade or replacement can be targeted towards the need for the technology modernization, optimization of LOBs (Line of Business), improving sustainability of the system, etc. The act of designing in architecture is a complex process. System design documents and the system security plan can provide useful information about the security of software in the development phase. 1.1 Phase 0 . Enterprise Architecture Assessment Enable business transformation, strategic alignment, and effective IT investment decisions From business vision to architectural change Enterprise Architecture (EA) is the planning function between strategy formulation and implementation. The software is designed, purchased, programmed, developed, or otherwise constructed. For instance, integrity of audit records is most important (that none are added or deleted inappropriately, and that they are all accurate). Other methodologies already describe how to deliver software projects, this methodology helps provide the architecture to ensure that the delivery is Service Oriented. Introduction Who besides the original customer might have a use for or benefit from using this system? [1] Michelle Keeney, JD, PhD, et al. If sessions expire after 10 minutes of inactivity, then the window of opportunity for session hijacking is about 10 minutes long. It is important to note that nonmalicious use by threat actors may result in system vulnerabilities being exploited. The table below describes a method of generating the risk exposure statement. Software specification(or requirements engineering): Define the main functionalities of the software and the constrains around them. Transa… Threats are agents that violate the protection of information assets and site security policy. This paper describes the scope of AQA and its intended use; the evaluation methodology embodied in the AQA; the process of conducting an architecture assessment using the AQA; the current status of Risk Management Guide for Information Technology Systems (NIST 800-30). One is risks that may impact a domain system, such as a national or enterprise-wide system, that is by its nature a single point of failure (for example, a Red Telephone that fails to ring). Software Architecture. Technology assessment mainly includes the activities like analyzing and reviewing the various layers and association to each other in the system. Three activities can guide architectural risk analysis: known vulnerability analysis, ambiguity analysis, and underlying platform vulnerability analysis. Likewise, the number of risks mitigated over time is used to show concrete progress as risk mitigation activities unfold. Such a diagram would be a small part of a much larger overall system architecture and would only be diagrammed to this level of detail if it were protecting an important information asset that was the subject of some scrutiny. All the information assets that can be found should be gathered in a list to be coordinated with risk analysis. Contributions and reviews by Niels J. Bjergstrom, Pamela Curtis, Robert J. Ellison, Dan Geer, Gary McGraw, C.C. Who besides the original customer might have a use for or benefit from using this system? It was launched by the Object Management Group (OMG) in 2001. Code reviews might be valuable if an implementation already exists. Each … Unstructured external threats are usually generated by individuals such as crackers. 4. In addition to characterizing the monetary impact, the location in other dimensions may be useful or required. The customer is utilizing a Policy Management System (PMS) which is evolving as a global product over the time that triggered the need for architecture assessment. CIOs can’t avoid SOA today. This assessment is derived from the CERT Resilience Management Model (CERT-RMM), a process improvement model developed by Carnegie Mellon University’s Software Engineering Institute for managing operational resilience. Vendors apply the label, often speciously, to help sell their products. The Assessment starts with discovery phase where brainstorming sessions are conducted with the key stakeholders to explore and understand the existing system architecture, non-functional requirements, current business and technical challenges in the system.
