RBI Guidelines on Digital Payment Security Controls and Customer Protection Framework 2024

The RBI Digital Payment Security Controls and Customer Protection Framework 2024 establishes comprehensive security requirements for payment system operators, banks, and fintech entities handling digital transactions. It mandates implementation of additional factor authentication (AFA), transaction velocity controls, real-time fraud monitoring with machine learning capabilities, and stringent customer grievance redressal mechanisms. The framework introduces zero-liability provisions for customers in unauthorized transactions, prescribes incident reporting timelines, and requires periodic security audits by CERT-In empanelled auditors. It consolidates previous circulars on card-not-present transactions, tokenization, and payment aggregator guidelines into a unified compliance structure.

• Enhanced customer confidence through mandatory zero-liability protection for unauthorized digital transactions reported within defined timelines, reducing customer acquisition friction for payment platforms
• Standardized security baseline across payment ecosystem reducing fragmentation, with clear technical requirements for encryption (AES-256), tokenization, and secure key management practices
• Improved fraud detection capabilities through mandated real-time transaction monitoring systems with configurable risk scoring, benefiting entities like PhonePe, Google Pay, and Paytm in reducing fraud losses
• Regulatory clarity on liability allocation between issuers, acquirers, and payment aggregators, reducing disputes and legal costs in fraud scenarios
• Accelerated digital payment adoption through customer protection measures, supporting India's vision of reducing cash dependency and achieving higher UPI transaction volumes

• Inadequate investment in AI/ML-based fraud detection systems by smaller payment banks and cooperative banks, with many still relying on rule-based systems unable to detect sophisticated fraud patterns
• Delayed tokenization implementation by smaller merchants and payment gateways despite RBI deadlines, with many still storing actual card credentials in violation of PCI-DSS and RBI norms
• Insufficient customer awareness programs about liability protection timelines and reporting mechanisms, leading to delayed fraud reporting beyond zero-liability windows
• Weak implementation of transaction velocity limits and cooling periods by some UPI apps and prepaid payment instrument issuers, enabling enumeration attacks and account takeovers
• Inconsistent incident response protocols across payment intermediaries, with several entities failing to meet the 6-hour critical incident reporting requirement to RBI and CERT-In

• In October 2023, BharatPe identified a credential stuffing attack affecting over 15,000 merchant accounts due to weak AFA implementation, requiring emergency security upgrades and customer notification under the framework's breach disclosure norms.
• HDFC Bank faced regulatory scrutiny in early 2024 when its internet banking platform experienced a three-hour outage during peak transaction hours, triggering framework requirements for business continuity testing and redundancy improvement within payment-critical systems.
• Paytm Payments Bank received RBI directions in January 2024 partly due to persistent KYC and transaction monitoring deficiencies, highlighting gaps in implementing the framework's customer due diligence and suspicious transaction reporting requirements for wallet operations.

• Invest in advanced behavioral biometrics and device fingerprinting technologies beyond basic AFA, as implemented by ICICI Bank's InstaBIZ platform, to detect account takeover attempts in real-time
• Establish cross-industry threat intelligence sharing platforms similar to the Financial Services Information Sharing and Analysis Center (FS-ISAC) model, enabling faster detection of emerging fraud vectors across payment networks
• Implement comprehensive simulation-based security testing including red team exercises and payment fraud war-gaming scenarios quarterly, rather than relying solely on annual VAPT assessments
• Develop customer-facing transaction monitoring dashboards with real-time alerts and temporary lock capabilities, similar to features offered by HDFC Bank and Axis Bank mobile apps, empowering customers as first line of defense
