# Wireless Intrusion Response Playbook
A Wireless Intrusion Response Playbook is a structured, sequenced set of procedures that security teams execute when unauthorized or anomalous wireless activity is detected on or near an organization's network. It exists because wireless environments introduce attack vectors that differ fundamentally from wired infrastructure: the physical medium is unbounded, rogue devices can appear without physical access, and containment cannot rely on disconnecting a cable. The playbook solves the problem of inconsistent, ad hoc responses that result in evidence destruction, incomplete containment, and missed recurrence. Without a pre-approved procedure, analysts waste critical minutes debating authority and sequence. With one, the team moves from detection to containment to recovery on a defined timeline, every time, regardless of which analyst is on call.
The playbook is distinct from a general Network Incident Response Playbook because wireless threats propagate beyond physical perimeters, require specialized radio-frequency (RF) detection tools, and involve attack methods like evil twin access points and deauthentication floods that do not exist in wired networks. It addresses threats across all wireless protocols including Wi-Fi (IEEE 802.11 variants), Bluetooth, Zigbee, Z-Wave, cellular-based IoT protocols, and near-field communication (NFC). The playbook defines who does what, in what order, under what authority, and with what tools, from the moment an alert fires to the moment normal operations resume and lessons are documented.

The wireless intrusion response playbook operates through five sequential phases, each with defined time targets, responsible roles, and decision gates. While some investigative actions run concurrently with containment, the sequence of authority and escalation remains fixed.
Activation triggers come from multiple sources: Wireless Intrusion Prevention System (WIPS) alerts, Security Information and Event Management (SIEM) correlation rules, user reports of unexpected network behavior, or threat intelligence feeds matching known wireless attack patterns. The first responder, typically a SOC analyst on duty, opens the playbook and begins immediate triage.
Triage answers three critical questions within 15 minutes: Is this a true positive or false positive? What is the apparent scope? Is the incident ongoing or historical? The analyst queries the WIPS management console for the rogue device's BSSID, signal strength readings from multiple sensors, and operating channel. If RF spectrum analyzers are deployed, signal capture initiates immediately to preserve the radio signature.
The analyst cross-references the BSSID against the authorized device inventory. Signal strength readings from three or more sensors enable triangulation of approximate physical location. A severity classification is assigned: Critical means active evil twin or deauthentication attacks are confirmed, or client devices are actively connecting to rogue infrastructure. High severity means a rogue AP is broadcasting but no client association is detected. Medium severity means anomalous RF activity is present but attribution remains inconclusive.
Containment actions depend directly on severity classification. For Critical incidents, the Network Operations Center is pre-authorized to push containment SSID blocks via the WIPS, sending targeted deauthentication frames to clients connected to the rogue AP and redirecting them to legitimate infrastructure. Simultaneously, switch ports associated with any physically identified rogue devices are quarantined using 802.1X enforcement or manual VLAN reassignment to isolated segments.
For client-compromise incidents, affected endpoints are removed from the wireless VLAN through Network Access Control (NAC) policy and placed in a remediation VLAN where they can be accessed for forensic imaging but cannot reach production resources.
Evidence preservation runs parallel to containment. The analyst captures the complete WIPS alert log with UTC timestamps, packet captures from the 802.11 frame level including beacon and probe response frames from rogue devices, NetFlow or IPFIX records from the wireless controller for the affected time window, and authentication logs from the RADIUS server showing client association attempts and successes.
A concrete example illustrates this phase: At 10:47 AM, a retail organization's WIPS fires an alert for an unauthorized BSSID operating on channel 6 with an SSID identical to the corporate guest network. Signal strength data from four sensor points places the source in the northeast parking lot corner. The analyst escalates to Critical severity because two client devices have associated with the rogue AP. The NOC pushes WIPS containment at 10:58 AM, severing the unauthorized associations. A security officer dispatched to the parking lot with a spectrum analyzer locates a battery-powered device attached under a window ledge at 11:09 AM. The device is photographed, bagged without powering down to preserve volatile memory, and handed to the incident commander for chain-of-custody documentation.
The investigation team reconstructs the complete timeline using synchronized log sources. Root cause analysis determines whether the rogue AP was planted by an external attacker, deployed by an uninformed employee for convenience, or introduced through a compromised vendor device. Impact assessment identifies which client credentials or data may have been exposed during the window the rogue infrastructure was active.
Indicators of Compromise (IOCs) are systematically extracted: the rogue BSSID, attacker MAC addresses captured in frame analysis, IP addresses issued by rogue DHCP services, and hashes of any malicious payloads captured in packet analysis. These IOCs are submitted to the threat intelligence platform for enrichment and shared via STIX/TAXII protocols if the organization participates in Information Sharing and Analysis Centers.
Recovery includes rotating wireless pre-shared keys or issuing new certificates if 802.1X was in use and credential compromise is suspected. Affected endpoints are reimaged from known-good baselines or have their wireless profiles cleared and reconfigured. Monitoring frequency on the affected RF zone increases for 30 days post-incident.
Return-to-normal criteria require no anomalous RF activity detected for 48 consecutive hours, all affected endpoints verified clean through scanning and behavioral analysis, and the incident commander's written sign-off documented in the case management system.
A structured lessons-learned session identifies detection gaps, authorization gaps, and process failures. The playbook is updated with new decision trees or tool configurations discovered during the incident. Detection rules are tuned based on specific indicators observed. This phase ensures that each incident strengthens the organization's wireless security posture rather than simply returning to the previous baseline.

Without a wireless intrusion response playbook, organizations face predictable and well-documented consequences: extended dwell times, contaminated evidence, incomplete containment, and repeated incidents because root causes are never fully addressed.
The business impact of uncontained wireless intrusions extends far beyond the immediate technical environment. Evil twin attacks that capture employee credentials provide attackers with access to cloud services, VPNs, and partner portals long after the physical device is discovered and removed. In retail and hospitality environments handling payment card data, a regulatory compliance clock starts the moment compromise is suspected. The Payment Card Industry Data Security Standard (PCI DSS) requires documented incident response procedures as a condition of maintaining compliance status.
Historical incidents demonstrate the cost of inadequate wireless incident response. Following WPA2 adoption in enterprise environments, attackers systematically targeted retailers and hospitality chains by deploying rogue APs in parking lots and adjacent spaces. These attacks succeeded because WIPS deployments were incomplete and incident response procedures failed to address wireless-specific scenarios. Organizations discovered intrusions only when card fraud patterns emerged weeks later. Dwell times in several publicly reported cases exceeded 30 days, during which thousands of payment card records were exfiltrated. A functional wireless intrusion response playbook, paired with properly configured WIPS infrastructure, would have reduced dwell time to hours in these scenarios.
Common misconceptions persist about wireless incident response requirements. The first is that WPA3 or 802.1X authentication eliminates the need for wireless incident response procedures. Authentication controls reduce the probability of unauthorized association, but they do not prevent rogue AP deployment, deauthentication attacks against management frames, or compromised endpoints acting as wireless pivot points after successful authentication. The playbook addresses what happens after preventive controls fail or are bypassed. Prevention and response are complementary security layers, not substitutes.
A second misconception limits wireless incident response to corporate Wi-Fi environments. Bluetooth-based attacks against conference room devices, Zigbee exploitation of building management systems, and cellular command-and-control channels for IoT implants all constitute wireless intrusions requiring structured response procedures specific to those protocols. Organizations that scope their wireless incident response playbook only to 802.11 networks leave documented gaps that attackers can exploit.
The financial impact of wireless incident response failures compounds over time. Each uncontained incident provides attackers with longer access to credentials and data. Regulatory fines for inadequate incident response can reach millions of dollars. Customer trust, once lost due to publicized wireless security failures, requires years and significant investment to rebuild. A well-executed wireless intrusion response playbook, tested through regular exercises and updated based on current threat intelligence, represents one of the highest return-on-investment security controls available to organizations operating wireless infrastructure.

CDA approaches the Wireless Intrusion Response Playbook through the Planetary Defense Model (PDM) under the Security Posture Hygiene (SPH) domain, with operational coordination from Threat Intelligence and Detection (TID). The methodology is Autonomous Posture Command (APC), expressed in CDA's operational principle: "Your posture adapts. Your hygiene never sleeps."
CDA does not treat the wireless intrusion playbook as a static document reviewed annually during compliance audits. It functions as a living operational artifact that is continuously tested, updated, and integrated with automated detection pipelines. When a WIPS alert fires, CDA's APC framework has pre-positioned the response: severity thresholds, containment authorities, evidence capture sequences, and escalation contacts exist as machine-readable configurations, not PDFs stored in document repositories.
CDA's SPH domain addresses wireless hygiene as a continuous posture requirement. The authorized BSSID inventory is reconciled against live RF sensor data on a scheduled basis, not only when alerts fire. Unauthorized devices are detected during routine sweeps rather than exclusively during active incidents. Posture measurement includes the gap between detected wireless devices and authorized inventory as a standing metric reported to security leadership.
The TID domain integrates wireless-specific IOCs into the continuous threat intelligence pipeline. When a rogue AP BSSID or deauthentication attack signature is confirmed during an incident, that indicator is immediately compared against threat intelligence from sector-specific Information Sharing and Analysis Centers and commercial feeds. If the indicator matches known threat actor tooling, incident severity escalates automatically and response transitions to an aggressive containment posture.
CDA's implementation differs from standard approaches through the pre-authorization model. Containment actions for wireless incidents, including WIPS-based deauthentication of rogue clients and switch port quarantine, are pre-approved by the CISO up to defined severity thresholds. Analysts execute containment within the first 60 minutes without requiring approval calls. This eliminates the most common source of dwell-time extension in wireless incident response: approval chain delays.
CDA maintains tabletop exercises specific to wireless intrusion scenarios on a quarterly basis, ensuring the playbook reflects current tool configurations and that all assigned roles have executed procedures in simulated environments within the past 90 days. These exercises include physical location of simulated rogue devices using RF tools, not just theoretical discussions of procedures.
