Welcome to the CompTIA Security+ course — a practical, exam-aligned program designed to build foundational cybersecurity skills and help you protect IT environments. Are you ready to boost your cybersecurity capabilities and defend against modern threats? This course balances conceptual knowledge with hands-on labs so you can quickly apply what you learn. Hands-on Labs The course includes multiple browser-based labs so you can practice commands and repeat examples without installing software locally. When you start a lab, you’ll see a terminal similar to this:
The labs run in your browser — no local setup required. Use them to try commands, reproduce examples, and reinforce concepts covered in the lesson.
Course overview Below is a high-level progression of the course content and the core skills you’ll develop.

Module-by-module breakdown We follow a logical sequence that starts with controls and fundamentals, then moves into applied cryptography, threat analysis, operational security, and finally design and governance.
  • Security controls — Learn how to categorize controls (administrative, technical, physical), when to apply them, and how they reduce risk.
  • Fundamental security concepts — Understand the CIA triad (confidentiality, integrity, availability) and related principles such as non-repudiation, AAA (authentication, authorization, accounting), and zero trust.
A presentation slide titled "Fundamental Security Concepts" showing the "CIA Triad" with the "Availability" element highlighted. A small circular video window with an instructor is visible in the bottom-right corner.
  • Physical security and process controls — Cover physical safeguards, honeypots, gap analysis, change management processes, business process considerations, and the documentation needed to support secure operations.
  • Cryptography — Study symmetric and asymmetric encryption, public key infrastructure (PKI), certificates, obfuscation, hashing, and salting, with practical examples and hands-on exercises.
A presentation slide titled "Public Key Infrastructure" illustrating asymmetric encryption with a public key (freely available) and a private key (secret) and a note that data encrypted with one key is decrypted with the other. A small circular video thumbnail of an instructor appears in the bottom-right.
Threats, vulnerabilities, and mitigations You’ll learn to identify and classify threat actors, understand motivations and common attack vectors, and apply mitigation strategies.

Key topics include:
  • Social engineering and human-based mitigations
  • Malware families, behaviors, and detection indicators
  • Application and network attacks (common exploit techniques)
  • Platform-specific vulnerabilities (software, firmware, and mobile)
  • Virtualization security features, system hardening, and asset control
Hands-on exercises reinforce these topics, including network scanning and discovery using tools such as Nmap. Security operations and ongoing processes This section covers practical, repeatable activities that maintain and improve organizational security posture:
  • Wireless and mobile security (protocols, hardening, best practices)
  • Vulnerability management and patching cycles
  • Monitoring, logging, and incident response fundamentals
A presentation slide about Wi‑Fi Protected Access 3 (WPA3) showing a shield-with-wifi graphic and three feature callouts: Latest Protocol, Enhanced Protection, and Modern Defenses. There's also a small circular video overlay of an instructor in the bottom right.
Enterprise security, automation, and scripting Learn how identity and access management (IAM) are implemented at scale and how automation and scripting can improve consistency, efficiency, and security operations.
A presentation slide titled "Automation and Scripting – Use Cases" with colorful gears labeled "Scripting," "Automation," and "IT Resources and Processes," and side boxes listing Efficiency, Consistency, and Security. A small circular video feed of a presenter appears in the bottom-right corner.
Security architecture, design, and management The final course sections emphasize secure system models, communication protections, data security, governance, risk management, and the documentation that supports security controls. Hands-on challenges — such as steganography exercises — help you practice detection and analysis techniques.
