Course content

8 Chapters • 39 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Cybersecurity Concepts and Landscape

  • Lesson 1 • Security Frameworks and Standards Overview

    Surveys widely adopted control frameworks and risk management standards. Provides a reference structure for organising security programmes.

  • Lesson 2 • Threat Actors and Motivations

    Profiles nation-states, cybercriminals, insiders, and hacktivists. Understanding actor motivation shapes defensive prioritisation.

  • Lesson 3 • Core Security Principles and Terminology

    Introduces the CIA triad, authentication, authorisation, and non-repudiation. Establishes shared vocabulary used throughout the entire course.

  • Lesson 4 • Attack Surfaces and Attack Vectors

    Maps digital, physical, and human attack surfaces across enterprise environments. Connects surface exposure to likely exploitation paths.

Chapter 2See details

Networking Fundamentals for Security

  • Lesson 1 • Network Segmentation and Architecture

    Covers DMZ design, VLANs, and zero-trust segmentation principles. Segmentation limits lateral movement and contains breach impact.

  • Lesson 2 • IP Addressing and Routing Concepts

    Explains IPv4 and IPv6 addressing, subnetting, and routing decisions. Accurate address knowledge is prerequisite for firewall and access control configuration.

  • Lesson 3 • Core Network Protocols and Services

    Examines DNS, DHCP, HTTP/S, SMTP, and FTP from a security perspective. Identifies protocol weaknesses exploited in common attacks.

  • Lesson 4 • Network Models and Protocol Stack

    Covers OSI and TCP/IP models, layer functions, and protocol roles. Provides the structural lens for analysing all subsequent network security topics.

  • Lesson 5 • Packet Capture and Traffic Analysis

    Teaches capture methodology and interpretation of packet-level data. Directly enables anomaly detection and incident investigation skills.

Chapter 3See details

Operating System Security Fundamentals

  • Lesson 1 • System Hardening Techniques

    Applies CIS benchmark concepts to reduce attack surface on both platforms. Hardening directly reduces exploitable entry points.

  • Lesson 2 • User and Access Management

    Implements least-privilege, role-based access, and account lifecycle controls. Proper access management prevents unauthorised resource use.

  • Lesson 3 • Windows Security Architecture

    Explores Windows authentication, privilege model, and registry security. Establishes the host-level foundation for endpoint defence.

  • Lesson 4 • System Logging and Monitoring

    Configures event logging, log forwarding, and baseline monitoring on host systems. Logs are the primary evidence source for incident detection.

  • Lesson 5 • Linux Security Architecture

    Covers Linux file permissions, user management, and kernel security features. Provides parallel host-security knowledge for mixed environments.

Chapter 4See details

Cryptography and Secure Communications

  • Lesson 1 • Cryptography Fundamentals

    Defines encryption, hashing, and digital signatures with mathematical intuition. Provides conceptual grounding before applied protocol study.

  • Lesson 2 • Secure Protocol Implementation

    Applies cryptographic primitives in TLS, SSH, IPsec, and VPN protocols. Connects theory to the protocols learners encounter in practice.

  • Lesson 3 • Public Key Infrastructure

    Explains certificate authorities, certificate lifecycle, and trust chains. PKI underpins TLS, code signing, and identity verification.

  • Lesson 4 • Symmetric and Asymmetric Algorithms

    Compares AES, RSA, ECC, and related algorithms on security and performance. Algorithm selection directly affects system security posture.

  • Lesson 5 • Cryptographic Weaknesses and Attacks

    Identifies deprecated algorithms, weak key practices, and implementation flaws. Recognising weaknesses prevents deployment of insecure cryptography.

Chapter 5See details

Threats, Vulnerabilities, and Attack Techniques

  • Lesson 1 • Malware Classification and Behaviour

    Categorises viruses, worms, ransomware, rootkits, and spyware by behaviour. Behavioural understanding drives detection and response decisions.

  • Lesson 2 • Vulnerability Assessment Concepts

    Introduces CVSS scoring, vulnerability scanning, and prioritisation frameworks. Structured assessment translates threat knowledge into remediation action.

  • Lesson 3 • Network-Based Attack Techniques

    Covers denial-of-service, man-in-the-middle, and packet injection attacks. Network attack knowledge informs firewall and IDS rule design.

  • Lesson 4 • Web Application Attack Techniques

    Examines SQL injection, XSS, CSRF, and broken authentication vulnerabilities. Web attacks are among the most prevalent threat vectors in practice.

  • Lesson 5 • Social Engineering and Phishing

    Analyses phishing, spear-phishing, vishing, and pretexting techniques. Human exploitation bypasses technical controls and requires behavioural defences.

Chapter 6See details

Network and Perimeter Defence

  • Lesson 1 • Wireless Network Security

    Secures Wi-Fi with WPA3, enterprise authentication, and rogue AP detection. Wireless networks present unique perimeter challenges requiring dedicated controls.

  • Lesson 2 • Firewall Technologies and Rule Design

    Compares packet-filter, stateful, and next-generation firewalls and their rule logic. Correct rule design is the primary perimeter control mechanism.

  • Lesson 3 • Intrusion Detection and Prevention Systems

    Covers signature-based and anomaly-based IDS/IPS deployment and tuning. Properly tuned sensors reduce alert fatigue and improve detection fidelity.

  • Lesson 4 • Secure Remote Access Solutions

    Implements VPN, zero-trust network access, and jump server architectures. Remote access controls prevent unauthorised entry from external networks.

  • Lesson 5 • Network Access Control and Authentication

    Applies 802.1X, NAC policies, and RADIUS/TACACS+ for network authentication. Access control ensures only authorised devices join the network.

Chapter 7See details

Security Monitoring and Incident Response

  • Lesson 1 • Threat Detection and Hunting

    Applies indicator-of-compromise searches and hypothesis-driven threat hunting. Proactive hunting finds threats that evade automated detection.

  • Lesson 2 • Security Information and Event Management

    Configures SIEM log ingestion, correlation rules, and dashboards for threat detection. SIEM is the central visibility platform for security operations.

  • Lesson 3 • Digital Forensics Fundamentals

    Applies evidence preservation, chain of custody, and forensic imaging techniques. Forensic integrity ensures findings are admissible and defensible.

  • Lesson 4 • Incident Response Lifecycle

    Executes preparation, detection, containment, eradication, and recovery phases. A structured lifecycle reduces breach impact and recovery time.

  • Lesson 5 • Post-Incident Review and Improvement

    Conducts lessons-learned analysis and translates findings into control improvements. Continuous improvement closes gaps revealed by real incidents.

Chapter 8See details

Risk Management and Security Governance

  • Lesson 1 • Compliance and Audit Management

    Maps controls to regulatory requirements and manages internal and external audits. Compliance evidence demonstrates due diligence to stakeholders.

  • Lesson 2 • Security Metrics and Reporting

    Defines KPIs, KRIs, and executive dashboards that communicate security posture. Metrics translate technical findings into business-relevant language.

  • Lesson 3 • Security Policy and Standards Development

    Drafts acceptable-use, data classification, and incident response policies. Policies formalise security expectations and provide enforcement authority.

  • Lesson 4 • Risk Assessment Methodologies

    Executes qualitative and quantitative risk assessments using likelihood and impact analysis. Risk assessment outputs drive resource allocation and control selection.

  • Lesson 5 • Third-Party and Supply Chain Risk

    Assesses vendor security posture and manages supply chain risk through contractual and technical controls. Third-party risk is a leading source of enterprise breaches.
