Lesson 2 • Application and Network Attack Vectors
Covers injection attacks, XSS, buffer overflows, DoS, and man-in-the-middle attacks. Links attack mechanics to the vulnerability classes they exploit.
Lesson 3 • Malware Categories and Behaviours
Distinguishes viruses, worms, ransomware, trojans, and spyware by behaviour. Builds threat recognition skills essential for incident response and exam questions.
Lesson 4 • Threat Intelligence and Indicators
Defines IOCs, threat feeds, and the MITRE ATT&CK framework. Prepares students to apply intelligence-driven defence in later operational chapters.
Lesson 5 • Vulnerability Scanning and Assessment
Introduces credentialed vs. non-credentialed scans, CVE scoring, and false positives. Establishes the assessment workflow used in penetration testing chapters.
Chapter 3HideHide detailsSee detailsNetwork Security Architecture
Network Security Architecture
Lesson 1 • Secure Network Protocols
Contrasts secure and insecure protocol pairs such as HTTPS vs. HTTP and SSH vs. Telnet. Reinforces why protocol selection directly affects confidentiality and integrity.
Lesson 2 • Intrusion Detection and Prevention
Differentiates IDS and IPS deployment modes and signature vs. anomaly detection. Positions these tools within the broader network monitoring strategy.
Lesson 3 • Firewall Types and Deployment
Compares packet-filtering, stateful, NGFW, and WAF technologies. Guides students in selecting and positioning firewalls within a layered architecture.
Lesson 4 • VPNs and Remote Access Security
Covers IPsec, SSL/TLS VPNs, split tunnelling, and always-on VPN models. Addresses secure remote access as a critical control in distributed work environments.
Lesson 5 • Network Segmentation and Zones
Explains DMZs, VLANs, and microsegmentation as isolation strategies. Connects segmentation to reducing lateral movement after a breach.
Chapter 4HideHide detailsSee detailsApplied Cryptography and PKI
Applied Cryptography and PKI
Lesson 1 • Certificate Lifecycle Management
Covers certificate issuance, renewal, revocation via CRL and OCSP, and pinning. Ensures students can maintain a healthy certificate environment over time.
Lesson 2 • Symmetric and Asymmetric Algorithms
Analyses AES, 3DES, RSA, ECC, and Diffie-Hellman in terms of strength and use case. Builds on Chapter 1 basics to enable algorithm selection decisions.
Lesson 3 • Cryptographic Protocols and Use Cases
Maps TLS handshake, S/MIME, PGP, and disk encryption to specific protection goals. Reinforces protocol selection as a practical cryptographic decision.
Lesson 4 • Public Key Infrastructure Design
Explains CA hierarchies, root CAs, intermediate CAs, and trust chains. Provides the structural knowledge needed to deploy and manage enterprise PKI.
Lesson 5 • Hashing Algorithms and Integrity
Covers MD5, SHA-1, SHA-2, SHA-3, and HMAC for data integrity verification. Explains why weak hashes create collision vulnerabilities in authentication systems.
Chapter 5HideHide detailsSee detailsIdentity and Access Management
Identity and Access Management
Lesson 1 • Directory Services and Federation
Explains LDAP, Active Directory, SAML, OAuth, and OpenID Connect. Prepares students to configure federated identity for cloud and hybrid environments.
Lesson 2 • Authentication Factors and Methods
Defines something you know, have, and are, plus location and behaviour factors. Establishes the authentication taxonomy used throughout IAM design decisions.
Lesson 3 • Privileged Access Management
Addresses PAM solutions, just-in-time access, and credential vaulting. Reduces insider threat risk by controlling and auditing elevated account usage.
Lesson 4 • Multi-Factor Authentication Implementation
Examines TOTP, HOTP, push notifications, and hardware keys for MFA. Connects MFA deployment to reducing credential-based attack success rates.
Lesson 5 • Access Control Models
Compares DAC, MAC, RBAC, ABAC, and rule-based access control. Guides selection of the appropriate model based on organisational security requirements.
