Learning Objectives:
- Implement data encryption for AI training datasets at rest using industry-standard tools.
- Configure secure communication channels (data in transit) for data ingestion into an ML platform.
- Apply role-based access control (RBAC) to limit access to sensitive AI assets, including data and trained models.
- Use data masking and anonymization techniques to protect personally identifiable information (PII) within datasets.
- Securely deploy an AI model endpoint and protect the data exchanged during the inference phase.

Overview
Artificial intelligence (AI) systems, particularly those based on Machine Learning (ML), rely heavily on vast amounts of data for training and operation. The security of this data—both the raw input and the resulting models—is paramount to maintaining privacy, compliance, and system integrity. This lab is designed to provide a comprehensive, hands-on experience in implementing essential data security controls across the AI life cycle. The primary focus will be on meeting encryption requirements for data at rest and in transit, and establishing robust data safety protocols to prevent unauthorized access, leakage, and tampering.

Key terms and descriptions
Adversarial Example
A subtle, intentional perturbation of an input designed to cause an AI model to make a mistake, often leading to misclassification.
AI Data Security
The practice of protecting the data used by and generated from AI systems from unauthorized access, corruption, or theft throughout its life cycle
Anonymization
The process of removing or modifying personally identifiable information (PII) from a dataset so that the data subject cannot be identified
Confidential Computing
A technology that protects data in use by performing computation in a hardware-based, attested, and verifiable trusted execution environment (TEE)
Data Leakage
The unintentional exposure of sensitive information from a training dataset, often through poorly secured storage or model outputs
Data Masking
A technique where sensitive data is obscured or replaced with realistic, but nonsensitive, data to protect privacy while maintaining data utility for testing or training
Data Minimization
The principle that only the minimum amount of personal data necessary to achieve a specified purpose should be collected and processed
Data Provenance
The record of the origin and history of a piece of data, including where it came from, what transformations it underwent, and who accessed it
Data Safety
A broad term encompassing the measures and controls implemented to ensure the confidentiality, integrity, and availability of data, especially in the context of AI systems
Differential Privacy
A system for publicly sharing information about a dataset by describing the patterns of groups within the dataset while withholding information about individuals
Encryption at Rest
The process of encrypting data when it is stored on a physical medium, such as a hard drive or cloud storage bucket, to prevent unauthorized access
Encryption in Transit
The process of encrypting data as it moves from one location to another, typically over a network, often using protocols like TLS/SSL
Fully Homomorphic Encryption (FHE)
An advanced encryption method that allows computations to be performed on encrypted data without decrypting it first, enabling secure data processing
Inference Security
The security measures applied to the deployed AI model and the data it processes during the prediction or decision-making phase
Key Management System (KMS)
A system for managing cryptographic keys, including their generation, storage, usage, and destruction
Model Poisoning
A type of adversarial attack where an attacker injects malicious data into the training set to corrupt the integrity of the resulting AI model
Role-Based Access Control (RBAC)
A security mechanism that restricts system access to authorized users based on their role within an organization
Secure Enclave
A protected area of a processor that is isolated from the rest of the system, designed to protect sensitive data and code from unauthorized access
Secure ML Pipeline
A set of automated processes for building, training, and deploying ML models that incorporates security checks and controls at every stage
Transport Layer Security/Secure Sockets Layer (TLS/SSL)
Transport layer security/secure sockets layer, cryptographic protocols designed to provide communication security over a computer network
