Point of Sale
PCI-DSS compliance at the endpoint. Secure POS terminals, manage multi-location access, and protect cardholder data — from flagship stores to seasonal pop-ups.
PCI-DSS Compliance for POS Systems
Every POS terminal that processes, stores, or transmits cardholder data is in scope for PCI-DSS. CtrlLayer provides the endpoint-level controls that QSAs and ISAs look for during assessments.
Secure System Configurations
PCI-DSS v4.0 Requirement 2.2.2 mandates that vendor default accounts are removed or disabled. CtrlLayer removes persistent admin accounts on POS terminals entirely. No default passwords, no shared admin credentials, no local accounts with unnecessary privileges. System configuration changes require policy-authorized elevation.
Anti-Malware Protection
Requirement 5.2 requires anti-malware on all systems commonly affected by malware. CtrlLayer's application control prevents unauthorized executables from running on POS terminals — including RAM scrapers, keyloggers, and other POS-specific malware that signature-based AV frequently misses.
Restrict Access by Business Need
Requirement 7.1 mandates access controls that limit access to system components and cardholder data to individuals whose job requires it. CtrlLayer enforces role-based elevation — cashiers run POS software, managers access back-office reports, and only authorized IT staff can install software or modify configurations.
Physical Access Controls
While primarily a physical security requirement, 9.5.1 addresses protecting POI devices from tampering. CtrlLayer's USB lockdown prevents unauthorized hardware attachments to POS terminals — skimming devices, unauthorized peripherals, and rogue USB devices are blocked and alerted immediately.
Log and Monitor All Access
Requirement 10.2 requires audit trails for all access to system components. CtrlLayer's hash-chain audit log captures every elevation event, application execution, USB device connection, and policy change on POS terminals. Tamper-evident logs satisfy 10.3.2 integrity requirements.
Information Security Policy
Requirement 12.3 mandates risk assessments and 12.6 requires security awareness training. CtrlLayer provides the continuous endpoint risk telemetry that feeds risk assessments and the policy enforcement that backs up awareness training with technical controls.
Franchise & Multi-Location Management
Retailers with dozens or hundreds of locations need centralized security management without requiring on-site IT at every store. CtrlLayer's multi-tenant architecture was designed for exactly this model.
- Central policy management with per-location customization — a flagship store with 20 POS terminals and a kiosk with one terminal share the same security baseline but can have location-specific rules
- Regional manager visibility — district and regional managers see their locations without access to others, maintaining proper access boundaries
- Franchise model support — franchisees can manage their own locations within corporate security guardrails enforced by the franchisor
- Remote deployment — new store openings can be secured from HQ without sending IT staff to the location
- Consolidated audit reporting across all locations for PCI-DSS annual assessments
Multi-Location Architecture
Seasonal Worker Access Management
Retail hiring surges during holidays mean hundreds of temporary workers who need system access fast — and need that access revoked just as fast when they leave.
Rapid Onboarding
Seasonal workers are assigned to a "Seasonal Staff" policy group that provides exactly the access they need — POS application, inventory lookup, schedule viewing — and nothing else. No admin rights, no system settings, no software installation. Onboarding takes minutes, not hours.
Time-Bounded Access
Seasonal access policies include automatic expiration dates. When the holiday season ends, access revokes automatically — no IT tickets needed, no orphaned accounts. Workers who transition to permanent roles are simply moved to a different policy group.
Reduced Insider Risk
High turnover creates insider threat risk. CtrlLayer ensures that seasonal workers cannot install unauthorized software, access back-office systems, connect personal USB devices, or modify POS configurations. The attack surface for temporary personnel is minimized by default.
POS Network Isolation Monitoring
PCI-DSS requires that the cardholder data environment (CDE) be segmented from non-CDE networks. Network segmentation is your first line of defense — but it is only effective if you continuously verify it. CtrlLayer monitors endpoint network behavior to catch segmentation failures.
- Detect POS terminals communicating with non-CDE network segments — immediate alert on segmentation breach
- Identify rogue devices on the POS network by monitoring for unexpected MAC addresses and protocols
- Alert on POS terminals initiating outbound connections to unauthorized internet destinations
- Monitor for lateral movement between POS terminals — a key indicator of RAM scraper propagation
- Baseline normal POS communication patterns (payment processor, inventory system, receipt printer) and flag deviations
POS Network Monitoring
USB Lockdown on POS Terminals
USB ports on POS terminals are attack vectors — for skimming hardware, malware-laden drives, and unauthorized data extraction. CtrlLayer locks them down while preserving legitimate peripheral functionality.
Block Storage Devices
All USB mass storage devices are blocked on POS terminals by default. No thumb drives, no external hard drives, no phone data connections. Every blocked device attempt is logged with device serial number, timestamp, and user identity.
Allow Approved Peripherals
Barcode scanners, receipt printers, cash drawers, and payment terminals connected via USB continue to function normally. CtrlLayer distinguishes between USB device classes — HID devices and approved peripherals are allowed while storage devices are blocked.
Skimmer Detection
When an unauthorized USB device is connected to a POS terminal, CtrlLayer blocks it and generates an immediate alert. This provides an early warning system for physical skimming attacks, supplementing regular POS terminal inspections required by PCI-DSS Requirement 9.5.1.
