8 weeks · About 7 hours per week

Week 1

WLAN Security Fundamentals and Risk Assessment

  • Define the core WLAN threat categories (eavesdropping, rogue AP, evil twin, deauthentication, on-path) and write a one-line business impact statement for each.

  • Explain how the CIA triad maps to specific 802.11 weaknesses, including open authentication, shared key, and unencrypted management frames.

  • Perform a risk assessment on a hypothetical small-office WLAN using likelihood and impact scoring, then rank the top five risks.

  • Distinguish between vulnerability, threat, and risk using WLAN examples so the terms are not conflated on scenario questions.

Your checkpoint

A one-page risk register with at least eight WLAN risks scored for likelihood and impact, plus a ranked top-five list with a one-sentence mitigation each.

Week 2

WLAN Security Fundamentals and Risk Assessment & 802.11 Security Architecture and Frame Protection

  • Describe the 802.11 frame types (management, control, data) and identify which frames are unprotected in each security generation.

  • Diagram the 802.11 state machine from unauthenticated and unassociated through authenticated and associated, noting where security exchanges occur.

  • Explain how 802.11w management frame protection (PMF) protects deauthentication, disassociation, and action frames, and what breaks without it.

  • Compare open system and shared key authentication and explain why shared key authentication weakens security.

Your checkpoint

A hand-drawn or digital state-machine diagram with annotated frame types and a short written note on where PMF applies and where it does not.

Week 3

WPA, WPA2, WPA3 and Robust Security Networks

  • Contrast WPA, WPA2, and WPA3 across encryption cipher, integrity method, key management, and handshake, including TKIP, CCMP, and GCMP.

  • Trace the WPA2 four-way handshake step by step and explain how the PMK, PTK, ANonce, SNonce, and MIC fit together.

  • Explain WPA3-SAE, forward secrecy, and the dragonfly exchange at a conceptual level, and why SAE resists offline dictionary attacks.

  • Identify WPA3 transition mode behavior and the downgrade risks it introduces.

  • Compare personal and enterprise modes and state when each is appropriate.

Your checkpoint

A comparison table of WPA, WPA2, and WPA3 covering cipher, integrity, handshake, key length, and known weaknesses, plus a numbered four-way handshake walkthrough.

Week 4

WPA, WPA2, WPA3 and Robust Security Networks & 802.1X Authentication and EAP Methods

  • Map the 802.1X roles (supplicant, authenticator, authentication server) and the controlled and uncontrolled ports to a real enterprise WLAN.

  • Sequence the EAP exchange from EAPOL-Start through EAP-Success and the subsequent key derivation.

  • Compare EAP-TLS, EAP-TTLS, PEAP, and EAP-FAST on server certificate requirements, client certificate requirements, and inner-method exposure.

  • Explain why PEAP without server certificate validation enables an evil-twin credential harvest.

Your checkpoint

An 802.1X message-flow diagram from EAPOL-Start to key installation, with a table comparing at least four EAP methods on certificate needs and tunnel properties.

Week 5

802.1X Authentication and EAP Methods & RADIUS, PKI and Certificate Infrastructure

  • Describe RADIUS accounting and authorization attributes (for example, tunnel attributes and VLAN assignment) and how they influence WLAN policy.

  • Explain RADIUS shared secrets, message authenticator, and why RADIUS should be tunneled or protected in transit.

  • Outline a PKI hierarchy (root, intermediate, issuing CA) and the role of certificate revocation via CRL and OCSP in 802.1X.

  • Describe how to enroll and validate a server certificate for EAP so clients can trust the authentication server.

  • Identify common PKI failure modes in WLAN deployments, such as expired certificates and missing CA trust on clients.

Your checkpoint

A PKI and RADIUS architecture diagram showing CA hierarchy, RADIUS server, authenticator, and supplicant, with a checklist of certificate validity and revocation checks.

Week 6

WLAN Monitoring, Intrusion Detection and Incident Response

  • Explain WIDS and WIPS functions, including rogue AP detection, evil-twin detection, and deauthentication flood detection.

  • Describe how rogue AP classification works using wired-side correlation and why false positives occur.

  • Draft an incident response sequence for a detected rogue AP, from triage through containment and post-incident review.

  • Identify the log sources and metrics that support WLAN security monitoring.

Your checkpoint

A one-page incident response runbook for a rogue AP detection, including triage steps, containment actions, escalation, and evidence to preserve.

Week 7

Secure Guest, BYOD and Guest Network Design & Wireless Security Policy, Compliance and Best Practices

  • Design a guest network that isolates guest traffic from internal resources using VLANs, ACLs, and client isolation.

  • Compare guest access models (captive portal, sponsored access, self-registration) and state the security tradeoffs of each.

  • Draft BYOD onboarding controls covering device posture, certificate-based onboarding, and separation of personal and corporate data.

  • Summarize the policy elements a WLAN security standard should contain, including password policy, key rotation, and acceptable use.

Your checkpoint

A guest and BYOD network design brief with a segmentation diagram, access control rules, and a list of onboarding controls.

Week 8

Wireless Security Policy, Compliance and Best Practices & WLAN Security Fundamentals and Risk Assessment

  • Assemble a compliance checklist mapping WLAN controls to common frameworks such as PCI DSS wireless requirements and general least-privilege practices.

  • Review the full domain list and close knowledge gaps by re-testing the weakest two domains.

  • Practice scenario-based questions under timed conditions and analyze every wrong answer for the underlying concept.

  • Write a personal post-exam action plan for keeping WLAN security knowledge current.

Your checkpoint

A timed 60-question practice set with a written error log explaining the root cause of each miss and the concept to review.

Milestones

Week 2: Can explain the 802.11 state machine and name which frame classes are unprotected without PMF, without notes.

Week 4: Can draw the 802.1X and four-way handshake flows from memory and state the certificate requirements of four EAP methods.

Week 6: Can describe rogue AP detection and containment steps and produce the incident runbook from memory in under 15 minutes.

Week 8: Scores at least 80 percent on the timed 60-question practice set with a complete error log.
