Domain 117% of exam

Basic AI Concepts Related to Cybersecurity

This domain covers foundational AI concepts through a security lens. You need to understand AI types and techniques, how data is secured throughout the AI pipeline, and the complete AI lifecycle with security at every stage. While the smallest domain by weight, this knowledge underpins everything else on the exam.

Key Topics

LLMsTransformersGANsRAGPrompt EngineeringAI LifecycleData Processing Pipeline

Must-Know Concepts

  • Types of AI: Generative AI, Machine Learning, Statistical learning, Transformers, Deep learning, NLP, LLMs, SLMs, GANs — know what each does and how they relate
  • Model training approaches: supervised learning (labeled data), unsupervised learning (pattern discovery), reinforcement learning (reward-based). Know when each applies
  • Fine-tuning concepts: epoch (one complete pass through training data), pruning (removing unnecessary model parameters), quantization (reducing numerical precision to shrink model size)
  • Prompt engineering: zero-shot (no examples), one-shot (one example), multi-shot (multiple examples), system prompts vs user prompts, system roles, prompt templates
  • Data processing pipeline: cleansing, verification, lineage, integrity, provenance, augmentation, and balancing — know what each step accomplishes
  • Data types in AI: structured (databases, spreadsheets), semi-structured (JSON, XML), unstructured (text, images, audio)
  • RAG architecture: how vector storage and embeddings work to augment AI responses with external data without retraining
  • Watermarking: techniques to mark AI-generated content for identification and provenance tracking
  • Complete AI lifecycle stages: business use case through data collection, preparation, model development, evaluation, deployment, validation, monitoring, and feedback
  • Human-centric AI: human-in-the-loop, human oversight, and human validation — when and why each is needed

Common Exam Traps

Fine-tuning MODIFIES the model weights. RAG does NOT modify the model — it only augments the prompt with retrieved data
Transformers are the architecture behind LLMs (like GPT). They are not a separate type of AI but a specific neural network architecture
Data provenance (origin) and data lineage (transformation history) are different concepts. Provenance is WHERE it came from; lineage is HOW it was transformed
The AI lifecycle is iterative, not linear. Monitoring feeds back into data collection and model updates
Zero-shot means NO examples in the prompt. It does not mean the model has zero training — the model still has its pre-trained knowledge
Quick Check: Basic AI Concepts Related to Cybersecurity

Question 1 of 2

An organization wants to improve an AI model's responses by providing relevant company documentation at query time WITHOUT modifying the model's weights. Which approach should they use?

Domain 240% of exam

Securing AI Systems

The heaviest domain at 40% — expect roughly 24 questions on this topic alone. Covers AI threat modeling, security controls, access controls, data protection, monitoring/auditing, and the full catalog of AI-specific attacks with their compensating controls. Master this domain or you will not pass.

Key Topics

OWASP Top 10 for LLMsMITRE ATLASPrompt FirewallsGuardrailsGateway ControlsEncryptionMonitoringAccess Controls

Must-Know Concepts

  • OWASP Top 10 for LLM Applications AND ML Security Top 10 — these are two separate lists covering different AI security concerns
  • MITRE ATLAS: adversarial tactics and techniques specific to AI systems. Know how it differs from MITRE ATT&CK
  • Model controls: model evaluation, guardrails (output constraints), and prompt templates (structured input formatting)
  • Gateway controls: prompt firewalls, rate limiting, token limits, input limits, modality limits, and endpoint access restrictions
  • Three types of access control: model access (who can query), data access (who can see training/inference data), agent access (what AI agents can do), plus network and API access
  • Data encryption in three states: at rest (stored), in transit (network), and in use (processing). Know controls for each state
  • Data safety techniques: anonymization (irreversible), classification labels, redaction (removal), masking (hiding), minimization (collecting only what is needed)
  • Monitoring dimensions: prompt monitoring (queries and responses), log monitoring with sanitization and protection, response confidence scores, rate monitoring, and AI cost monitoring (prompts, storage, response, processing costs)
  • Auditing requirements: hallucination detection, accuracy measurement, bias and fairness assessment, and access auditing
  • Full attack catalog: prompt injection, data poisoning, jailbreaking, hallucinations, input manipulation, bias introduction, guardrail circumvention, model inversion, model theft, supply chain attacks, transfer learning attacks, model skewing, output integrity, membership inference, insecure output handling, model DoS, sensitive info disclosure, insecure plugin design, excessive agency, overreliance
  • Compensating controls for each attack: prompt firewalls, guardrails, access controls, data integrity checks, encryption, prompt templates, rate limiting, and least privilege

Common Exam Traps

OWASP has TWO AI-related Top 10 lists: LLM Top 10 and ML Security Top 10. Do not confuse them — they address different risk categories
Guardrails must be TESTED and VALIDATED. Simply deploying guardrails without testing gives false security. The exam specifically calls out guardrail testing
Prompt firewalls filter INPUT. Guardrails constrain OUTPUT. Know which direction each control protects
Model DoS is different from traditional DDoS. It specifically targets AI model resources (compute, tokens) rather than network bandwidth
Excessive agency means an AI agent has too many permissions or too much autonomy, not that it is producing too many responses
Insecure plugin design is about third-party plugins that extend AI capabilities without proper security validation
Quick Check: Securing AI Systems

Question 1 of 2

A security team discovers that an attacker has been submitting carefully crafted queries to their public-facing LLM to reconstruct a copy of the proprietary model. Which attack type does this describe?

Domain 324% of exam

AI-Assisted Security

This domain covers how AI is used as a security tool (defensive) and how attackers leverage AI (offensive). Also covers automation of security tasks using AI. Expect questions on specific tool types, AI-enhanced attack vectors like deepfakes, and AI-driven automation in CI/CD and incident response.

Key Topics

IDE PluginsChatbotsMCP ServerDeepfakesAI AgentsCI/CD SecurityAnomaly Detection

Must-Know Concepts

  • AI-enabled security tool types: IDE plugins, browser plugins, CLI plugins, chatbots, personal assistants, and MCP servers
  • AI security use cases: signature matching, code quality/linting, vulnerability analysis, automated penetration testing, anomaly detection, pattern recognition, incident management, threat modeling, fraud detection, translation, and summarization
  • Deepfake categories: impersonation (identity fraud), misinformation (unintentional), and disinformation (intentional deception)
  • AI-enhanced attack vectors: adversarial networks, automated reconnaissance, social engineering amplification, code obfuscation, automated data correlation
  • Automated attack generation capabilities: attack vector discovery, payload generation, malware creation, honeypot detection, and DDoS amplification
  • AI automation of security tasks: low-code/no-code scripting, document synthesis and summarization, incident response ticket management
  • Change management with AI: AI-assisted approvals, automated deployment and rollback
  • AI in CI/CD: code scanning, software composition analysis (SCA), unit testing, regression testing, model testing, automated deployment and rollback
  • AI agents: autonomous AI systems that can take actions, make decisions, and interact with external tools and systems

Common Exam Traps

Deepfake impersonation is NOT the same as deepfake disinformation. Impersonation targets a specific person; disinformation spreads false narratives
MCP server is listed as a security tool type. Know what Model Context Protocol does and how it enables standardized tool integration
AI-assisted approvals in change management are not fully autonomous. They ASSIST human decision-making, not replace it
Automated penetration testing using AI still requires human oversight. AI accelerates the process but does not eliminate the need for skilled testers
Quick Check: AI-Assisted Security

Question 1 of 2

A security operations center wants to use AI to automatically identify unusual patterns in network traffic that do not match known attack signatures. Which AI security use case does this describe?

Domain 419% of exam

AI Governance, Risk, and Compliance

This domain covers organizational governance structures, responsible AI principles, AI-specific risks, and compliance frameworks. Know the key AI-related job roles, the difference between voluntary frameworks and enforceable regulations, and how organizations manage AI risks including Shadow AI.

Key Topics

EU AI ActNIST AI RMFISO AI StandardsOECD StandardsAI Center of ExcellenceResponsible AI

Must-Know Concepts

  • Organizational governance structures: AI Center of Excellence, AI policies and procedures
  • AI-related roles: data scientist, AI architect, ML engineer, platform engineer, MLOps engineer, AI security architect, AI governance engineer, AI risk analyst, AI auditor, data engineer — know what each role does
  • Responsible AI principles: fairness, reliability/safety, transparency, privacy/security, explainability, inclusiveness, accountability, consistency, awareness training
  • AI-specific risks: bias, data leakage, reputational loss, model accuracy and performance degradation, intellectual property risks, autonomous system risks
  • Shadow IT and Shadow AI: unauthorized use of IT and AI tools. Shadow AI is employees using AI tools without organizational approval
  • EU AI Act: risk-based classification (unacceptable, high, limited, minimal risk). Unacceptable risk is banned; high risk requires strict compliance
  • NIST AI RMF: voluntary framework for AI risk management
  • Corporate AI policies: sanctioned vs unsanctioned AI tools, private vs public models, sensitive data governance
  • Third-party compliance evaluations: assessing AI vendors and partners for compliance

Common Exam Traps

EU AI Act is LEGALLY ENFORCEABLE. NIST AI RMF, OECD standards, and ISO standards are VOLUNTARY. This is a critical distinction
Shadow AI is not just Shadow IT — it specifically refers to unauthorized AI tool usage, which carries unique risks like data leakage to AI providers
Data sovereignty requirements may affect where AI models can be trained and where data can be stored, especially under the EU AI Act
An AI auditor and an AI risk analyst have different roles: auditors verify compliance and accuracy, risk analysts identify and assess potential risks
Sanctioned AI tools are approved by the organization. Unsanctioned AI tools are not approved. Using unsanctioned tools is Shadow AI
Quick Check: AI Governance, Risk, and Compliance

Question 1 of 2

An organization discovers that multiple departments are using a public AI chatbot to summarize confidential business documents without IT approval. Which risk does this represent?

Concepts You Must Not Confuse

These pairs appear on nearly every exam. Learn the difference and you'll avoid the most common traps.

Prompt Injection vs Jailbreaking

Use Prompt Injection when…

Attacker inserts malicious instructions to make the model perform unintended actions, such as leaking data or ignoring its system prompt.

Use Jailbreaking when…

Attacker crafts prompts specifically to bypass the model's built-in safety guardrails and content policies to produce restricted outputs.

Exam trap

Prompt injection tricks the model into doing something unintended. Jailbreaking specifically targets safety guardrails. Both manipulate prompts, but the goals differ: injection is about unauthorized actions, jailbreaking is about bypassing restrictions.

Model Inversion vs Model Theft (Extraction)

Use Model Inversion when…

Attacker queries the model repeatedly to reconstruct or infer sensitive data that was used during training.

Use Model Theft (Extraction) when…

Attacker queries the model repeatedly to build a functionally equivalent copy of the model itself, stealing the intellectual property.

Exam trap

Model inversion steals TRAINING DATA. Model theft steals THE MODEL. Both use repeated querying, but the target is different. Rate limiting helps mitigate both.

Prompt Firewalls vs Guardrails

Use Prompt Firewalls when…

Filter and inspect prompts BEFORE they reach the AI model. Block malicious, policy-violating, or suspicious inputs at the gateway level.

Use Guardrails when…

Constrain model OUTPUTS to ensure responses comply with safety, accuracy, and policy requirements. Operate after the model generates a response.

Exam trap

Prompt firewalls protect the INPUT side. Guardrails protect the OUTPUT side. The exam tests whether you know which control addresses which direction of the AI pipeline.

Supervised Learning vs Unsupervised Learning

Use Supervised Learning when…

Model is trained on labeled data where the correct answers are provided. Used for classification and regression tasks like spam detection.

Use Unsupervised Learning when…

Model finds patterns in unlabeled data without predefined answers. Used for clustering, anomaly detection, and dimensionality reduction.

Exam trap

Supervised = labeled data, known outcomes. Unsupervised = unlabeled data, discovers hidden patterns. The exam also tests reinforcement learning (learns through reward/penalty feedback), which is neither.

Misinformation vs Disinformation

Use Misinformation when…

False or inaccurate information spread WITHOUT deliberate intent to deceive. The person sharing it may believe it is true.

Use Disinformation when…

False information deliberately created and spread WITH intent to deceive, manipulate, or cause harm.

Exam trap

Misinformation is unintentional. Disinformation is intentional. Both can be amplified by deepfakes, but the INTENT is the distinguishing factor. The exam tests this distinction in the context of AI-enhanced attack vectors.

LLMs (Large Language Models) vs SLMs (Small Language Models)

Use LLMs (Large Language Models) when…

Very large neural networks with billions of parameters, trained on massive datasets. Broad capabilities but expensive to run and require significant compute resources.

Use SLMs (Small Language Models) when…

Smaller, more focused models with fewer parameters. More efficient, cheaper to deploy, and suitable for specific tasks with limited compute resources.

Exam trap

LLMs are general-purpose and resource-heavy. SLMs are task-specific and efficient. The exam may present scenarios where an SLM is the better choice due to cost or deployment constraints.

Data Anonymization vs Data Masking

Use Data Anonymization when…

Irreversibly removes personally identifiable information so the original data cannot be recovered. Used when data must be permanently de-identified.

Use Data Masking when…

Hides sensitive data while preserving format and structure, often reversibly. Used when original data must be recoverable by authorized parties.

Exam trap

Anonymization is PERMANENT and IRREVERSIBLE. Masking is typically REVERSIBLE. If the question asks about irreversible data protection, the answer is anonymization. Also know redaction, which completely removes sensitive content.

NIST AI RMF vs EU AI Act

Use NIST AI RMF when…

A voluntary risk management framework providing guidelines and best practices for managing AI risks. No legal enforcement.

Use EU AI Act when…

A legally binding regulation that classifies AI systems by risk level and imposes mandatory compliance requirements with penalties for violations.

Exam trap

NIST AI RMF is voluntary guidance. EU AI Act is enforceable law. The exam may present scenarios where you need to determine which applies: voluntary best practice vs. legal compliance obligation.

Top Mistakes to Avoid

Confusing prompt injection (unauthorized actions) with jailbreaking (bypassing safety guardrails) — both manipulate prompts but have different goals
Mixing up model inversion (extracting training data) with model theft (copying the model itself)
Thinking guardrails and prompt firewalls do the same thing — prompt firewalls filter inputs, guardrails constrain outputs
Confusing RAG with fine-tuning — RAG augments prompts at query time without changing the model; fine-tuning actually modifies model weights
Treating the EU AI Act (legally binding) and NIST AI RMF (voluntary framework) as equivalent — one is enforceable law, the other is guidance
Not knowing there are TWO OWASP Top 10 lists for AI: one for LLMs and one for ML Security, covering different risk categories
Confusing data provenance (where data came from) with data lineage (how data was transformed over time)
Thinking Shadow AI is the same as Shadow IT — Shadow AI specifically involves unauthorized AI tools and carries unique data leakage risks
Assuming encryption at rest and encryption in transit cover all scenarios — encryption in use (processing) is a third state tested on the exam
Forgetting that the AI lifecycle is iterative: monitoring and feedback loop back to earlier stages, it is not a one-way process
