Data Protection: Encryption, Data Loss Prevention and Privacy by Design

Cybersecurity and Digital Risk October 25, 2025
Enquire About This Course

Introduction

Data is the lifeblood of the modern enterprise, yet it is scattered across on-premises storage, cloud platforms, and endpoints, making protection a complex challenge. This course provides a strategic and technical deep dive into modern data protection mechanisms, focusing on key areas like encryption, Data Loss Prevention (DLP), and the mandatory implementation of Privacy by Design. Participants will learn how to identify, classify, and protect sensitive data throughout its entire lifecycle, ensuring compliance with global privacy regulations while enabling necessary data use for business purposes.

Objectives

The aim of this program is to equip security and privacy professionals with the strategic and technical skills required to design and implement a comprehensive, lifecycle-focused data protection strategy:

Target Audience

  • Data Protection Officers (DPOs) and Privacy Managers.
  • Data Security Architects and Engineers.
  • Compliance and GRC Professionals.
  • CISOs and Security Directors.
  • Cloud Security Specialists.
  • Database and Storage Administrators.
  • Legal Counsel focused on data privacy.

Methodology

  • Case studies on major data breaches and the role of DLP/encryption failure.
  • Group activity designing a data classification and discovery program.
  • Technical discussions comparing different encryption implementation models (e.g., TDE, client-side).
  • Practical exercises tuning a mock DLP rule-set to minimize false positives.
  • Role-playing a DPIA for a new product feature involving personal data.

Personal Impact

  • Expertise in designing and implementing full data lifecycle protection.
  • Credibility as a specialist in privacy regulations and compliance.
  • Ability to select and deploy appropriate encryption and key management systems.
  • Mastery of DLP technologies and operational procedures.
  • Enhanced understanding of Privacy by Design principles.
  • Skills to effectively manage data risk in multi-cloud environments.

Organizational Impact

  • Minimized risk of data breaches and significant regulatory fines.
  • Demonstrable compliance with global data protection laws (e.g., GDPR, CCPA).
  • Improved customer trust and enhanced organisational reputation.
  • More efficient data management through clear classification and governance.
  • Reduced insider threat risk via effective DLP enforcement.
  • Secure adoption of cloud services through effective data residency controls.

Course Outline

Unit 1: Data Protection Governance and Strategy

Section 1.1: Data Classification and Discovery
  • Developing a comprehensive data classification scheme (e.g., public, confidential, restricted).
  • Automated and manual techniques for data discovery and inventory.
  • Data flow mapping and identifying cross-border data transfers.
  • Establishing data ownership and accountability within the organisation.
Section 1.2: Privacy by Design and by Default
  • The seven foundational principles of Privacy by Design (PbD).
  • Integrating PbD into the System Development Lifecycle (SDLC).
  • Data minimization strategies and purpose limitation.
  • Conducting Privacy Impact Assessments (PIAs) and Data Protection Impact Assessments (DPIAs).

Unit 2: Encryption and Cryptographic Controls

Section 2.1: Encryption in the Data Lifecycle
  • Encryption at rest (disk, database, file-level) vs. encryption in transit (TLS/SSL).
  • Homomorphic Encryption and searchable encryption overview.
  • Tokenization and anonymization/pseudonymization techniques.
  • Regulatory requirements for strong encryption standards.
Section 2.2: Key Management Systems (KMS)
  • Designing a secure and resilient Key Management Infrastructure.
  • Hardware Security Modules (HSMs) and their role in key protection.
  • Lifecycle of cryptographic keys (generation, storage, rotation, destruction).
  • Managing keys across multi-cloud environments (e.g., AWS KMS, Azure Key Vault).

Unit 3: Data Loss Prevention (DLP) Implementation

Section 3.1: Designing the DLP Program
  • Defining sensitive data policies and detection rules (regex, exact data matching).
  • DLP deployment models: Endpoint, Network, and Cloud.
  • Techniques for reducing false positives and improving accuracy.
  • Integration of DLP with email and collaboration tools (e.g., MS Teams).
Section 3.2: Operationalizing DLP
  • Developing incident response and workflow for DLP alerts.
  • Tuning DLP policies based on business need and risk appetite.
  • The role of User Behavior Analytics (UBA) in DLP enforcement.
  • Measuring and reporting on DLP effectiveness and policy violations.

Unit 4: Data Protection in Cloud and Endpoint Environments

Section 4.1: Cloud Data Protection
  • Securing SaaS data (e.g., Salesforce, Office 365) using Cloud Access Security Brokers (CASBs).
  • Data residency and sovereignty requirements in multi-cloud.
  • Secure configuration of cloud storage (e.g., S3 buckets, Azure Blob Storage).
  • Implementing encryption and access controls in serverless databases.
Section 4.2: Endpoint and Mobile Data Protection
  • Full disk encryption and file-level encryption for mobile devices.
  • Mobile Device Management (MDM) and Mobile Application Management (MAM) controls.
  • Securing data in transit from endpoints to corporate networks.
  • The importance of access control in protecting data on unmanaged devices.

Unit 5: Data Governance and Emerging Trends

Section 5.1: Governance and Legal Requirements
  • Developing and enforcing data retention and destruction policies.
  • Responding to Data Subject Access Requests (DSARs).
  • Regulatory compliance oversight (GDPR, CCPA, HIPAA).
  • Managing data in third-party and vendor relationships.
Section 5.2: Future of Data Protection
  • The application of AI/ML for advanced data classification and risk scoring.
  • Confidential computing and securing data while in use (processing).
  • Data Mesh architectures and decentralized data governance.
  • The impact of post-quantum cryptography on current encryption standards.
