PhаrmаCаre Inc. оperates a highly autоmated pharmaceutical prоduction facility. Its industrial Control System (ICS) manages the entire manufacturing workflow—from raw material input to drug formulation, quality control, and packaging—ensuring precision, regulatory compliance, and operational efficiency. The ICS is tightly integrated with customer relationship management (CRM) and enterprise resource planning (ERP) systems to align production batches with hospital and clinic prescription orders. The architecture follows a typical ISA-95 / Purdue Model: Level Systems Level 0 - Field Devices Environmental and production sensors (temperature, humidity, vibration). Level 1 - Control Programmable Logic Controllers (PLCs) operating mixers, pumps, conveyors. Level 2 - Supervisory Supervisory Control and Data Acquisition (SCADA) and Human-Machine Interfaces (HMIs). Level 3 - Site Operations Manufacturing Execution System (MES) managing batch orders and quality tracking. Level 4 - Enterprise ERP, CRM systems storing batch-customer relationships and regulatory reports. Key components include: PLCs: Control dosing, mixing, and packaging machines based on predefined drug recipes. SCADA system: Provides centralized monitoring, alarm handling, and historical data logging. HMIs: Allow operators to intervene manually when necessary. Industrial IoT Sensors: Measure critical environmental parameters that affect drug quality. Batch Control System (ISA-88): Ensures precise execution and tracking of formulation batches. MES: Bridges shop floor operations with business systems and tracks work-in-progress. Data Historian: Records time-series production and environmental data. IoT Edge Gateways: Collect and transmit sensor data to the SCADA layer. Internal Firewalls and Segmentation: Separate operational technology (OT) from enterprise IT systems. A legacy IoT environmental sensor (monitoring humidity inside a mixing chamber) was compromised due to outdated firmware vulnerabilities. Attackers exploited this weakness to pivot into the ICS network, moving laterally to the SCADA server, extracting batch production logs, and correlating them with CRM data to uncover sensitive information linking: Specific production batches Prescription orders from clinics and hospitals Individual patient names, medications, dosages, and delivery schedules. Data Exposed: Patient personal identifiers (names) Medication types and strengths Fulfillment schedules (dates) Batch numbers (traceable to specific prescription orders) After the required analysis was developed during stage 1 – define the business objective of PASTA: Process for Attack Simulation and Threat Analysis, we built the following Business Impact Matrix (BIM). Asset (Component) CIA Priority (Confidentiality / Integrity / Availability) Business Impact if Compromised Programmable Logic Controllers (PLCs) I: High / A: High Incorrect drug formulation, dosage errors, mass product recalls, FDA violations, risk to patient safety. SCADA System I: High / A: High Loss of production visibility and control, failure to detect production anomalies, delayed incident response, regulatory non-compliance. Human-Machine Interfaces (HMIs) I: Medium / A: High Operators lose control and monitoring ability, unsafe manual overrides, production disruptions. Industrial IoT Sensors (Temperature/Humidity) I: High / A: Medium Production under improper environmental conditions, leading to drug instability, regulatory violations, and forced product recalls. Batch Control System (ISA-88) I: High / A: High Recipe manipulation leading to ineffective or dangerous medications, massive liability, and operational shutdown. Manufacturing Execution System (MES) C: Medium / I: High / A: High Loss of production scheduling, batch tracking, work-in-progress records; inability to fulfill customer orders or comply with audits. Data Historian Server C: Medium / I: High / A: Medium Loss of historical production data needed for audits and traceability; impacts regulatory reporting and legal defense. IoT Edge Gateway C: Medium / I: Medium / A: Medium Loss or manipulation of sensor data aggregation; incomplete production monitoring; possible missed environmental compliance thresholds. Internal Firewalls / Network Segmentation Devices C: Medium / I: High / A: High Enables lateral movement by attackers; allows cross-system compromises leading to massive cascading failures across ICS and CRM systems. CRM System (Prescription Orders) C: High / I: Medium / A: Medium Unauthorized disclosure of patient prescription data; severe HIPAA/GDPR fines; major reputational damage. Enumerate the privacy threats using the LINDDUN framework. For each threat identified, structure your answer as follows: [threat source] [prerequisites] can [threat action], which leads to [threat impact], negatively impacting [impacted assets]. Requirements: Use only information from the provided scenario. Cover at least one example of each LINDDUN threat type. Demonstrate an understanding of technical privacy attacks. Use the BIM to map the impact. Define the most effective control that would mitigate each enumerated threat. Observation 1: Base your threat enumeration exclusively on the scenario description. Observation 2: Ensure that at least one example from each LINDDUN category is provided. Rubric Criteria Excellent Good Needs Improvement Poor Threat Enumeration Structure (7 points) 7 points — All threats fully follow the [threat source] [prerequisites] can [threat action], which leads to [threat impact], negatively impacting [asset] format without errors. 5–6 points — Minor format errors or slight inconsistencies, but mostly correct and understandable. 3–4 points — Multiple format errors, missing elements (e.g., missing prerequisites, unclear actions). 0–2 points — Format ignored or threats not clearly structured. Coverage of LINDDUN Categories (7 points) 7 points — At least one accurate threat identified for each of the 7 LINDDUN categories (Linkability, Identifiability, Non-repudiation, Detectability, Information Disclosure, Unawareness, Non-compliance). 5–6 points — Missed 1 LINDDUN category, or one threat weakly justified. 3–4 points — Missed 2–3 LINDDUN categories, or threats are poorly tied to categories. 0–2 points — Missed 4+ categories; threats not properly classified. Mapping to Business Impact Matrix (BIM) (6 points) 6 points — All threats mapped correctly to BIM assets and business impacts (e.g., CRM system, SCADA, MES). 4–5 points — Minor errors (wrong asset selected once, or slight mismatch on impact). 2–3 points — Several wrong asset mappings; unclear or inconsistent impacts. 0–1 point — Little or no mapping to assets/impact; mapping arbitrary or missing. Definition of Controls (6 points) 6 points — Controls proposed are realistic, directly mitigate threats, and match privacy/security best practices for ICS. 4–5 points — Controls mostly appropriate but one or two vague or not optimal. 2–3 points — Many controls weak, ineffective, or poorly justified. 0–1 point — Controls missing, irrelevant, or incorrect. Clarity, Organization, and Technical Reasoning (4 points) 4 points — The answer is clearly structured, easy to follow, and shows strong technical reasoning. 3 points — Mostly clear, but minor organization or explanation flaws. 2 points — Difficult to follow; reasoning

Pаtrick wаkes up оne mоrning tо find thаt he has developed an enormous pimple right on the end of his nose. All throughout the school day he is absolutely sure that everyone is staring at the blemish, when in reality almost nobody cares enough about it to even look.
