Yоu аre pаrt оf the cybersecurity risk teаm at a regiоnal airport authority. The airport’s infrastructure includes smart baggage handling systems, passenger boarding systems connected to biometric scanners, a public Wi-Fi network, and flight operations systems integrated with third-party airline platforms. Recently, a penetration test highlighted multiple vulnerabilities: Unauthenticated API access to the boarding systems, Weak encryption on inter-airline data links, Possibility of pivoting from public Wi-Fi to back-end services via misconfigured routers. Your goal is to model potential attacks, help prioritize mitigation plans, and communicate risks to technical teams and executive leadership. Question: Which of the following approaches best leverages the strengths of attack trees and attack flows in this scenario?
A gоvernment аgency recently lаunched а clоud-based dоcument collaboration platform for interdepartmental work on sensitive reports. The platform allows authorized users to upload, edit, and share documents in real time. Access is controlled through SSO integrated with the agency's identity provider, and users are grouped by department (e.g., legal, finance, intelligence). The system includes audit logging and document version control. After deployment, an internal audit discovered that several documents marked as "confidential – internal only" were accessed and downloaded by contractors outside the department — without approval. Investigators traced the issue to an overly permissive access policy and an improperly shared folder that was inherited by contractor accounts due to misconfigured group permissions. Additionally, the document preview feature embedded external scripts without sanitization, exposing users to cross-site scripting (XSS) risks when opening shared documents. A PASTA risk assessment identified the following: Threat actors: Internal contractors and external attackers via shared document links. Attack vectors: Misconfigured folder inheritance, lack of validation in embedded document content. Vulnerabilities: Excessive access rights, lack of input sanitization, weak content security policy. Impact: Data leakage of sensitive government documents; potential client-side malware execution. Likelihood: High, due to shared workspaces and lack of document content control. Risk Level: High for confidentiality and integrity of documents and user sessions. Instructions: Based on the scenario above, write an analytical essay answering the following: 1. Identify a security design principle that was violated. For each principle, provide: A clear and concise definition, An explanation of how it was violated in this case, and A description of how it should have been applied in the system’s design. 2. Propose specific security controls (technical or administrative) that could have mitigated or prevented the attack. Your recommendations must align with the PASTA analysis above. Reference: https://cheatsheetseries.owasp.org/ Criteria Excellent (Full Points) Average (Partial Points) Poor (Few or No Points) Points 1. Identification and Definition of Security Principles (8 pts) Correctly identifies the relevant principles violated in the case and provides precise, technically accurate definitions of each. Identifies relevant principles, but definitions are incomplete, vague, or partially inaccurate. Identifies wrong or irrelevant principles, or definitions are missing or fundamentally incorrect. /8 2. Explanation of Principle Was Violated (8 pts) Provides clear, well-reasoned explanations of how the principle was specifically violated in the scenario, with strong connection to the case. Provides some explanation, but lacks clarity or only loosely connects violations to the scenario. Explanation is missing, generic, or not grounded in the scenario. /8 3. Description of How the Principles Should Be Applied (6 pts) Clearly describes how the principle should have been integrated into the design, showing strong understanding of secure system architecture. Provides a general description of principle application, but lacks specificity or technical depth. Descriptions are unclear, superficial, or missing. /6 4. Proposed Security Controls (8 pts) Proposes appropriate, technically sound controls (administrative or technical) that directly mitigate the identified risks based on PASTA findings. Control suggestions are partially relevant or only address some risks; some technical errors or oversights may exist. Controls are inappropriate, generic, or not linked to the PASTA findings or design principles. /8
A smаrt hоme аssistаnt recоrds vоice commands to improve the user experience. However, it also stores these recordings indefinitely and shares them with third-party developers for service enhancements, without informing users or obtaining explicit consent. According to the LINDDUN privacy threat model, which privacy threat category best describes this scenario?
In mid-2023, а regiоnаl hоspitаl deplоyed a new telemedicine platform integrated with electronic health records (EHR), enabling physicians to conduct video consultations and access patient data remotely. The platform includes a web dashboard for doctors, a mobile app for patients, and several backend APIs that facilitate appointment booking, video session coordination, and data synchronization with the central EHR system. Authentication is handled via OAuth 2.0, and video streaming relies on an embedded third-party SDK. Following unexplained disruptions, the hospital’s IT team discovered that several unauthorized users had gained partial access to the platform. A deeper investigation revealed that attackers had manipulated input fields in the appointment booking API to embed specially crafted function calls later evaluated by a vulnerable string-parsing component within the backend. This allowed the execution of arbitrary function calls, resulting in access to session tokens and partial exposure of patient data. Further logs revealed that the attackers had also used parameter guessing techniques to bypass poorly enforced API access controls and enumerate appointment metadata by incrementing internal appointment IDs. As part of the post-incident analysis team, your task is to characterize this attack and recommend appropriate mitigations. You are presented with the following CAPEC patterns: CAPEC-248: Command Injection: https://capec.mitre.org/data/definitions/248.html CAPEC-137: Parameter Alteration: https://capec.mitre.org/data/definitions/137.html CAPEC-43: Exploiting Multiple Input Interpretation Layers: https://capec.mitre.org/data/definitions/43.html Write an analytical essay addressing the following: Identify the most appropriate CAPEC pattern that aligns with the attacker’s method. Justify your choice by explaining why it is more precise than the other two options. Describe the step-by-step execution of the attack based on the selected CAPEC pattern. Be sure to include how the attacker manipulated input, bypassed controls, and escalated their impact. Map the attack to one or more STRIDE threat categories. Justify your mapping based on the attacker’s actions and the vulnerabilities exploited. Recommend technical and procedural mitigations that would reduce the likelihood or impact of this attack. Your response should consider input validation, API hardening, access control, and secure evaluation of dynamic content. Your answer will be graded based on technical accuracy, comparison reasoning, depth of analysis, and the quality of the mitigation strategy. Criteria Excellent (Full Points) Average (Partial Points) Poor (Few or No Points) Points 1. CAPEC Pattern Identification and Justification (9 pts) Correct CAPEC selected (CAPEC-137) with a clear, precise, and technically sound justification, comparing it effectively to the other two options. Correct CAPEC selected but with limited or vague justification, OR incorrect CAPEC with a partial rationale. Incorrect CAPEC selected with no clear justification, or only superficial comparison made. /9 2. Attack Description Using CAPEC (8 pts) Describes the full attack chain step-by-step using the selected CAPEC, clearly relating each phase to the scenario (access, injection, escalation, impact). Describes the attack with some logical flow, but misses one or more key steps or lacks clarity in linking to the CAPEC. Incomplete, vague, or generic description, or not clearly aligned with the selected CAPEC. /8 3. STRIDE Mapping and Explanation (7 pts) Identifies correct STRIDE categories (e.g., Tampering, Information Disclosure, Elevation of Privilege) and gives strong reasoning linked to the scenario. Identifies some relevant STRIDE threats but with limited explanation or unclear application to the case. STRIDE mapping is incorrect or missing, or reasoning is flawed or superficial. /7 4. Mitigation Strategy (Technical + Procedural) (6 pts) Recommends specific, technically accurate mitigations (e.g., input validation, schema enforcement, token handling), well-connected to the attack. Suggestions are partially correct or too generic (e.g., "use encryption" or "secure APIs" without details). Mitigations are generic, incorrect, or not linked to the vulnerabilities or case context. /6
