Lesson 1 • Threat and Vulnerability Concepts

Defines malware types, attack vectors, and vulnerability categories. Establishes the threat awareness needed before applying any defensive control.

Lesson 2 • Cryptography Fundamentals

Explains symmetric, asymmetric encryption, hashing, and PKI. Provides the cryptographic literacy required for secure communications and data protection.

Lesson 3 • Network Security Controls

Introduces firewalls, IDS/IPS, VPNs, and network segmentation. Applies networking knowledge to active defense of infrastructure.

Lesson 4 • Authentication and Access Control

Covers password policies, multi-factor authentication, and least-privilege principles. Directly extends user administration skills from the OS chapter.

Lesson 1 • Relational Database Concepts

Introduces tables, keys, relationships, and the relational model. Provides the conceptual foundation for schema design and SQL in later sections.

Lesson 2 • Database Administration Basics

Addresses user permissions, indexing, backups, and performance tuning. Connects security and reliability principles to database operations.

Lesson 3 • Database Design and Normalization

Teaches normal forms, dependency analysis, and schema refinement. Enables students to design efficient, anomaly-free database structures.

Lesson 4 • SQL Querying Essentials

Covers SELECT, INSERT, UPDATE, DELETE, and JOIN operations. Builds the query skills needed for data retrieval and manipulation tasks.

Lesson 1 • Code Quality and Documentation

Addresses naming conventions, comments, refactoring, and README writing. Ensures students produce maintainable code that others can understand and extend.

Lesson 2 • Scripting for System Automation

Applies shell and scripting language syntax to automate OS and file tasks. Builds directly on command-line skills from the OS chapter.

Lesson 3 • Programming Logic and Concepts

Introduces variables, data types, control flow, and functions. Establishes language-agnostic logic skills applicable to any scripting or coding task.

Lesson 4 • Working with Files and APIs

Covers reading and writing files, parsing formats, and calling REST APIs. Enables students to integrate IT tools and exchange data programmatically.

Lesson 1 • Cloud Service and Deployment Models

Defines IaaS, PaaS, SaaS, and public, private, and hybrid cloud models. Enables students to match business requirements to the appropriate cloud strategy.

Lesson 2 • Virtualization Concepts and Tools

Explains hypervisors, virtual machines, and containers. Provides the foundational understanding needed before working with cloud infrastructure.
