Description

This curriculum spans the design, deployment, and defensive operations of wireless security within a SOC, comparable in technical breadth to a multi-phase internal capability build for enterprise-grade 802.11 threat detection and response.

Module 1: Wireless Threat Landscape and SOC Integration

Decide which wireless threat intelligence feeds to integrate into the SOC’s SIEM based on signal reliability and coverage of 802.11 vulnerabilities.
Map wireless intrusion detection events to MITRE ATT&CK techniques for consistent incident classification across hybrid environments.
Implement automated correlation rules to link rogue access point alerts with endpoint telemetry and user authentication logs.
Establish thresholds for wireless anomaly alerts to reduce false positives without missing low-and-slow attacks like deauthentication floods.
Coordinate wireless monitoring responsibilities between network operations and SOC teams to eliminate coverage gaps during incident response.
Define escalation paths for wireless incidents that trigger IR playbooks, including criteria for involving physical security teams.

Module 2: Wireless Monitoring Architecture and Sensor Placement

Deploy dedicated wireless IDS sensors in monitor mode across multiple floors to ensure full RF coverage without blind spots.
Configure channel-hopping intervals on sensors to balance detection latency and channel coverage in dense 5 GHz environments.
Integrate wireless sensor data with network TAPs and SPAN ports to correlate Layer 2 wireless events with wired traffic flows.
Assess risks of using virtualized sensors in cloud-managed Wi-Fi deployments where physical access is limited.
Isolate management traffic for wireless sensors on a separate VLAN to prevent lateral movement during compromise.
Validate sensor placement through periodic site surveys to detect new physical obstructions or signal interference sources.

Module 3: Authentication and Identity Management for Wireless Access

Enforce 802.1X with EAP-TLS for enterprise Wi-Fi, requiring certificate-based client authentication instead of password-only methods.
Integrate RADIUS server logs with the SOC’s logging pipeline to detect repeated failed EAP exchanges indicative of credential attacks.
Implement dynamic VLAN assignment based on user role and device type, synchronized with identity provider attributes.
Monitor for unauthorized use of PEAP-MSCHAPv2 by enforcing server certificate validation on all supplicants.
Respond to compromised employee credentials by revoking associated client certificates and forcing re-enrollment.
Enforce device compliance checks via NAC integration before granting wireless network access, blocking non-compliant endpoints.

Module 4: Detection of Rogue and Misconfigured Access Points

Develop signatures to distinguish between authorized guest networks and unauthorized consumer-grade access points masquerading as legitimate SSIDs.
Use MAC OUI databases to flag access points from unapproved vendors commonly used in shadow IT deployments.
Configure automated containment responses for rogue APs, including deauthentication frame injection with documented legal review.
Investigate false positives caused by neighboring enterprise networks with overlapping SSIDs and signal strength profiles.
Track persistent rogue AP incidents to specific departments for targeted security awareness interventions.
Validate containment effectiveness by verifying that deauthentication packets are delivered and the AP disconnects clients.

Module 5: Wireless Encryption and Protocol Vulnerability Management

Mandate WPA3-Enterprise for new deployments and enforce transition timelines for legacy WPA2-PSK systems.
Scan for devices that downgrade to WPA2 during connection attempts, indicating potential KRACK or Dragonblood attack surfaces.
Disable WPS on all managed access points due to inherent PIN brute-force vulnerabilities, even if not publicly exposed.
Monitor for use of RC4 or TKIP in mixed-mode networks and block legacy clients that cannot support CCMP/AES.
Conduct quarterly audits of certificate lifecycles used in EAP methods to prevent expired or weak-signature incidents.
Assess risk of Opportunistic Wireless Encryption (OWE) in public networks and its impact on SOC visibility.

Module 6: Incident Response and Forensics for Wireless Attacks

Preserve full packet captures from wireless sensors during active attacks for forensic timeline reconstruction.
Correlate deauthentication flood timestamps with user helpdesk tickets to identify targeted disruption campaigns.
Extract and analyze client association tables from APs to determine scope of session hijacking or evil twin attacks.
Use RF fingerprinting to attribute rogue devices when MAC addresses are spoofed or randomized.
Document chain of custody for seized wireless hardware involved in physical breach investigations.
Reconstruct attack sequences using PCAP, RADIUS logs, and DHCP assignments to support post-incident reporting.

Module 7: Policy Enforcement and Continuous Compliance Monitoring

Define acceptable use policies for personal hotspots and enforce detection through RF signature analysis.
Automate compliance checks for wireless configurations using configuration management tools and APIs from Wi-Fi vendors.
Generate exception reports for access points operating on non-standard channels or with transmit power above policy limits.
Integrate wireless security controls into audit frameworks such as NIST 800-171 or ISO 27001 for regulatory reporting.
Enforce segmentation policies by validating that guest Wi-Fi traffic is routed through firewall inspection points.
Conduct red team assessments of wireless defenses annually, with findings routed directly to SOC tuning workflows.

Module 8: Advanced Threat Hunting in Wireless Environments

Develop hunting queries to detect beacon frame anomalies, such as SSID flooding or malformed information elements.
Search for evidence of Wi-Fi sensing attacks using channel state information (CSI) manipulation in research-grade gear.
Profile normal client roaming behavior to identify lateral movement via wireless reassociation attacks.
Investigate use of software-defined radios (SDRs) near secure facilities by monitoring for unauthorized signal generation.
Correlate wireless probe request patterns with known device fingerprinting libraries to detect surveillance tools.
Track adoption of emerging protocols like Wi-Fi 6E and assess their monitoring gaps in existing SOC toolchains.
