WGU, Information Security and Assurance (C725), SET II Already Passed After determining the potential attack concepts, the next step in threat modeling is to perform ______________ analysis. ______... ________ analysis is also known as decomposing the application, system, or environment. The purpose of this task is to gain a greater understanding of the logic of the product as well as its interactions with external elements.Also known as decomposing the application ✔✔Reduction analysis Whether an application, a system, or an entire environment, it needs to be divided into smaller containers or compartments. Those might be subroutines, modules, or objects if you're focusing on software, computers, or operating systems; they might be protocols if you're focusing on systems or networks; or they might be departments, tasks, and networks if you're focusing on an entire business infrastructure. Each identified sub-element should be evaluated in order to understand inputs, processing, security, data management, storage, and outputs. Trust Boundaries, Data Flow Paths, Input Points, Privileged Operations, Details about Security Stance and Approach ✔✔The Five Key Concepts in the Decomposition process. In the decomposition process, any location where the level of trust or security changes. ✔✔Trust Boundaries In the decomposition process, the movement of data between locations ✔✔Data Flow Paths In the decomposition process, locations where external input is received ✔✔Input Points In the decomposition process, any activity that requires greater privileges than of a standard user account or process, typically required to make system changes or alter security ✔✔Privileged Operations In the decomposition process, the declaration of the security policy, security foundations, and security assumptions ✔✔Details about Security Stance and Approach The concept that most computers, devices, networks, and systems are not built by a single entity. ✔✔supply chain T or F When evaluating a third party for your security integration, you should consider the following processes:On-Site Assessment, Document Exchange and Review, Process/Policy Review, ThirdParty Audit ✔✔True When engaging third-party assessment and monitoring services, keep in mind that the external entity needs to show security-mindedness in their business operations. If an external organization is unable to manage their own internal operations on a secure basis, how can they provide reliable security management functions for yours? Investigate the means by which datasets and documentation are exchanged as well as the formal processes by which they perform assessments and reviews. ✔✔Document Exchange and Review Visit the site of the organization to interview personnel and observe their operating habits. ✔✔OnSite Assessment Request copies of their security policies, processes/procedures, and documentation of incidents and responses for review. ✔✔Process/Policy Review Having an independent third-party auditor, as defined by the American Institute of Certified Public Accountants (AICPA), can provide an unbiased review of an entity's security infrastructure, based on Service Organization Control (SOC) (SOC) reports. Statement on Standards for Attestation Engagements (SSAE) is a regulation that defines how service organizations report on their compliance using the various SOC reports. The SSAE 16 version of the regulation, effective June 15, 2011, was replaced by SSAE 18 as of May 1, 2017. The SOC1 and SOC2 auditing frameworks are worth considering for the purpose of a security assessment. The SOC1 audit focuses on a description of security mechanisms to assess their suitability. The SOC2 audit focuses on implemented security controls in relation to availability, security, integrity, privacy, and confidentiality. For more on SOC audits, see AICPA.For all acquisitions, establish minimum security requirements. These should be modeled from your existing security policy. The security requirements for new hardware, software, or services should always meet or exceed the security of your existing infrastructure. When working with an external service, be sure to review any service-level agreement (SLA) to ensure that security is a prescribed component of the contracted services. This could include customization of service-level requirements for your specific needs. ✔✔Third-Party Audi [Show More]
