WGU C706 Questions and Answers Latest Updated 2024/2025 (100% Solved)

WGU C706 Questions and Answers Latest Updated 2024/2025 (100% Solved) Stride is a classification scheme for characterizing/measuring known threats/vulnerabilities according to the kinds of exploit that are used (motivation of the attacker). It also focuses on the end results of possible attacks rather than on the identification of each specific attack. The STRIDE acronym is formed from the first letter of each of the following categories. Spoofing Identity Identity spoofing is a key risk for applications that have many users but provide a single execution context at the application and database level. In particular, users should not be able to become any other user or assume the attributes of another user. Tampering of Data Users can potentially change data delivered to them return it and thereby potentially manipulate client side validation, GET and POST results, cookies, HTTP headers, and so forth. The application should not send data to the user, such as interest rates or periods, which are obtainable only from within the application itself. The application should also carefully check data received from the user and validate that it is sane and applicable before storing or using it. Repudiation Users may dispute transactions if there is insufficient auditing or recordkeeping of their activity. Information Disclosure Denial of Service Application designers should avoid expensive resources such as large files, complex calculations, long queries. Elevation of Privilege All actions should be gated through an authorization matrix to ensure that only the permitted roles can access privileged functionality.

It also focuses on the end results of possible attacks rather than on the identification of each specific attack. DREAD Risk assessment model Damage How bad would an attack be? Ranks the extent of harm that occurs if a vulnerability is exploited. Reproducibility how easy is it to reproduce the attack? Ranks how often an attempt at exploiting a vulnerability really works. Exploitability / Vulnerability How much work is it to launch the attack? Measures the effort required to launch the attack. Affected users How may people will be impacted? Measures the number of installed instances of the system affected by the exploit. Discoverability How easy is it to discover the threat? States the likelihood that a vulnerability will be found by security researchers or hackers. Threat Model A threat model is a diagram and description that tells a story of how an attacker could exploit the vulnerability. This is a narrative approach to the attack that should help guide the mitigation techniques that need to be put in place to protect the system at that point. It can define the security of an application and reduces the number of vulnerabilities. It also has the 2 steps of identifying and prioritizing the vulnerabilities. Sequence Diagram Detailed breakdown of he communication that will occur between actors and system objects or components. A sequence diagram bridges the gap between the business analysis and the development analysis; this type of diagram can be considered a business description or a development description of system functionality. T-Map T-MAP defines a set of threat-relevant attributes for each layers or nodes. These attributes can be classified as either probability-relevant, size of loss of relevant or descriptive. These class attributes are primarily derived from Common Vulnerability Scoring System. CVSS SDLC Domains Planning Organization Project Definition, User Requirements Definition and System Requirement Definition Acquisition / Implementation User requirements definition, System Requirement Definition, Analysis and Design and System Build/ Prototype/ Pilot Deliver and Support Analysis and Design, System Build/ Prototype / Pilot, Implementation and Training and Sustainment. Monitoring User Requirements Definition, Systems Requirements Definition, Analysis and Design, System Build / Prototype /Pilot, Implementation and Training and Sustainment. Requirements analysis Phases that defines security functions that an application should satisfy. Testing Phases Security should be involved in all phases of SDLC, but expectation of vulnerabilities to identify weaknesses should be done in the testing phase. Incident Response Plan An incident response plan is organized approach to addressing and managing the aftermath of a security breach or compromise on a system or software. The goal is to handle the situation and limit damage and reduces recovery time and costs.
