    Catalogues current threat categories including insider threats, external attackers, and environmental hazards. Builds threat awareness needed for later risk assessment chapters.

  • Lesson 2 • Core Security Concepts and Principles

    Introduces confidentiality, integrity, and availability as the foundational triad. Connects these principles to every subsequent administrative decision in the course.

  • Lesson 3 • Legal and Regulatory Foundations

    Covers privacy obligations, data protection duties, and industry compliance requirements without referencing specific codes. Prepares administrators to align controls with regulatory expectations.

  • Lesson 4 • The Security Administrator Role

    Defines daily duties, authority boundaries, and accountability of a security administrator. Positions the role within broader IT and business governance structures.

  • Lesson 5 • Security Frameworks and Standards

    Surveys widely adopted security frameworks and control catalogues. Provides a reference structure for organising controls throughout the course.

Chapter 2See details

Risk Management and Security Governance

  • Lesson 1 • Risk Assessment Methodologies

    Compares qualitative and quantitative risk assessment approaches and their appropriate contexts. Provides the analytical foundation for all governance and control decisions.

  • Lesson 2 • Security Policy Development

    Guides creation of security policies, standards, and procedures aligned to business objectives. Establishes the policy hierarchy that governs all administrative controls.

  • Lesson 3 • Risk Treatment and Acceptance

    Covers risk mitigation, transfer, avoidance, and acceptance options with decision criteria. Connects risk scores to actionable treatment plans and residual risk tracking.

  • Lesson 4 • Audit and Continuous Compliance

    Establishes internal audit processes, continuous control monitoring, and audit evidence management. Ensures ongoing compliance posture is measurable and defensible.

  • Lesson 5 • Security Governance Structures

    Defines governance committees, security steering groups, and executive reporting relationships. Positions security administration within organisational decision-making authority.

Chapter 3See details

Identity and Access Management

  • Lesson 1 • Identity Lifecycle Management

    Covers provisioning, modification, and deprovisioning of user accounts. Establishes the full identity lifecycle as the backbone of access control.

  • Lesson 2 • Access Reviews and Auditing

    Establishes periodic access certification and continuous audit log review. Ensures access rights remain appropriate and detectable anomalies are flagged.

  • Lesson 3 • Privileged Access Management

    Addresses elevated account risks, just-in-time access, and privileged session monitoring. Reduces attack surface from administrative credential compromise.

  • Lesson 4 • Access Control Models

    Compares discretionary, mandatory, role-based, and attribute-based access control models. Guides selection of the appropriate model for different environments.

  • Lesson 5 • Authentication Methods and Policies

    Examines password policies, multi-factor authentication, and certificate-based authentication. Connects authentication strength to organisational risk tolerance.

Chapter 4See details

Network Security Administration

  • Lesson 1 • Firewall Configuration and Management

    Covers rule-set design, change management, and firewall log review. Connects proper firewall hygiene to reduced unauthorised access risk.

  • Lesson 2 • Secure Remote Access

    Addresses VPN technologies, remote desktop security, and zero-trust access for remote workers. Ensures remote connectivity does not expand the attack surface.

  • Lesson 3 • Network Architecture Security Principles

    Introduces defence-in-depth, segmentation, and DMZ design for secure networks. Provides the architectural thinking required before configuring individual controls.

  • Lesson 4 • Wireless Network Security

    Covers wireless encryption standards, rogue access point detection, and guest network isolation. Addresses the unique risks of wireless environments.

  • Lesson 5 • Intrusion Detection and Prevention

    Explains signature-based and anomaly-based detection, tuning, and alert triage. Builds the monitoring capability needed for incident detection in later chapters.

Chapter 5See details

Endpoint and System Hardening

  • Lesson 1 • Hardening Principles and Baselines

    Introduces secure configuration baselines, benchmarks, and the concept of minimal footprint. Establishes the methodology applied to all endpoint types in this chapter.

  • Lesson 2 • Application Whitelisting and Control

    Explains allow-listing, software restriction policies, and execution control mechanisms. Prevents unauthorised software from running on managed endpoints.

  • Lesson 3 • Patch and Vulnerability Management

    Establishes patch prioritisation, testing, and deployment workflows tied to vulnerability severity. Connects timely patching to measurable risk reduction.

  • Lesson 4 • Mobile Device Security

    Addresses mobile device management, encryption, and remote wipe capabilities for enterprise mobility. Extends hardening principles to devices outside the traditional perimeter.

  • Lesson 5 • Operating System Hardening

    Covers disabling unnecessary services, applying security templates, and managing local accounts. Directly reduces exploitable attack surface on servers and workstations.

Chapter 6See details

Data Security and Cryptography

  • Lesson 1 • Encryption at Rest and in Transit

    Applies encryption to stored data, databases, and network communications. Ensures data remains protected regardless of where it resides or travels.

  • Lesson 2 • Data Loss Prevention Controls

    Covers DLP policy creation, endpoint and network DLP agents, and incident response for data exfiltration alerts. Connects classification tiers to automated enforcement.

  • Lesson 3 • Public Key Infrastructure

    Explains certificate authorities, certificate lifecycle, and trust chain management. Enables administrators to operate or consume PKI services securely.
