Website Security for UK Parking Operators

Why Parking Operators Face Specific Data Security Challenges

Parking operators collect vehicle registration data at a scale few businesses match. An ANPR-equipped car park may record hundreds of vehicle movements per day, creating a database that links vehicle registrations to location, time, and in many cases driver identity and payment details.

The British Parking Association (BPA) and International Parking Community (IPC) both operate accreditation schemes that set standards for data handling. The ICO has specific guidance on ANPR data and has taken enforcement action against parking operators for failures in data protection. Websites that allow drivers to pay, appeal, or dispute parking charges are a natural target for fraud.

What Parking Operator Websites Handle

**Online payment portals** — Drivers pay parking charges, season tickets, and penalty charge notices through operator websites. These portals handle payment card data and link it to vehicle registrations and driver identities.

**Penalty charge notice appeals** — Appeal systems collect driver contact details, statements of circumstances, and supporting evidence. This data includes home addresses, employer information, and sometimes medical or personal circumstances submitted in mitigation.

**Season ticket and permit applications** — Applications for resident permits and season tickets collect full driver identity, vehicle details, and sometimes proof of address.

**ANPR data management** — Back-end systems that manage ANPR records link vehicle registrations to movement timestamps. This data, if accessed, creates a comprehensive record of vehicle movements over extended periods.

**Debt recovery referrals** — The handoff between parking operators and debt collection agencies involves the transfer of driver personal data. The security of that transfer and the systems managing it require careful attention.

Specific Vulnerabilities at Parking Operators

**Insecure penalty notice portals** — PCN payment and appeal portals sometimes use the PCN reference number as the only authentication factor. Anyone who can guess or access a PCN number can view the associated driver's data and potentially make payments or amendments.

**IDOR vulnerabilities in PCN management** — APIs and web interfaces that manage PCN records may not properly verify that the requesting user is authorised to view or modify a specific notice. An attacker could access any driver's personal data by incrementing a PCN reference.

**Payment portal vulnerabilities** — High-volume payment portals that handle card data are targeted specifically. Without a full PCI DSS compliant implementation, payment card data is at risk.

**ANPR data accessible beyond operational need** — ANPR databases accessible through web-based management systems require strict access controls. Overly permissive access allows data to be queried for surveillance or identity verification purposes beyond the lawful basis under which it was collected.

BPA, IPC, and ICO Obligations

Accredited parking operators have data retention limits on ANPR data — typically 90 days for non-enforcement records. Websites and back-end systems must enforce these limits automatically. The ICO's enforcement record in this sector includes fines for excessive retention and inadequate security of ANPR databases.

Yrzo AI scans parking operator websites and identifies vulnerabilities in PCN portals, payment systems, and customer-facing access controls that could expose driver data or enable fraudulent claim manipulation.
