WGU C706 Questions and Answers Latest 2022 Graded A Stride ✔✔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. STRIDE ✔✔classification scheme for characterizing/measuring known threats/vulnerabilities according to the kinds of exploit that are used or motivation of attacker. 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 seq [Show More]
