(6) efficient and effective dispute resolution mechanism and handling of customer grievance; and

(7) adequate and appropriate review mechanism followed by swift corrective action, in case any one of the above requirements is hampered or having high potential to get hampered.

The Board and Senior Management shall be responsible for implementation of this policy. The policy shall be reviewed at least annually. The bank may formulate this policy separately for its different digital products / services or include the same as part of its overall product policy.
The policy shall require that every digital payment product / service offered addresses the mechanics, clear definition of starting point, critical intermittent stages / points and end point in the digital payment cycle, security aspects, validations till the digital payment is settled, clear pictorial representation of digital path, exception handling, signing off of the above requirements, mechanism for carrying out User Acceptance Tests (UAT) in multiple stages before roll-out, sign off from multiple stakeholders [post User Acceptance Tests (UAT)], and data archival requirements.
The bank shall clearly articulate the need for an external assessment of the entire process including the logic, build, and security aspects of the application(s) supporting the digital product or service.
The bank shall incorporate appropriate processes into its governance and risk management programs for identifying, analysing, monitoring, and managing the specific risks, including compliance risk and fraud risk, associated with the portfolio of digital payment products and services on a continual basis and in a holistic manner.
The Senior Management of the bank shall have appropriate performance monitoring systems / key performance indicators for assessing whether the product or service offered through digital payment channels meets operational and security norms. As part of this process, the bank shall define product-level limits on the level of acceptable security risk, document specific security objectives, and performance criteria including quantitative benchmarks for:

(1) evaluating the success of the security built into the digital payment product or service;

(2) comparing actual results with projections and qualitative benchmarks on a periodic basis to detect and address adverse trends or concerns in a timely manner; and

(11) compliance with extant cybersecurity requirements; and

(12) compatibility aspects.

The risk assessment shall cover the surrounding ecosystem as well and address the need to protect and secure payment data (such as customer data, customer and beneficiary account details, payment credentials, and transaction data) and evaluate the resilience of systems. The internal Risk and Control Self-Assessment (RCSA) exercise shall cover the risks (inherent) and controls vis-à-vis the probability and impact of threats to arrive at residual risk. The bank shall maintain database of all systems and applications storing customer data in the payment ecosystem and compliance with applicable Payment Card Industry (PCI) standards in each of the systems (notwithstanding mandatory requirements of certification / standard accreditation). The periodicity of RCSA may be determined by the bank based on changes in the scope of the risk assessment. In case of vendors, the bank shall evaluate the RCSA conducted by the vendor.
The bank shall evaluate the risks associated with the chosen technology platforms, application architecture, both on the server and client side. Further, the bank shall undertake a review of the risk scenarios and existing security measures based on incidents affecting its services, before any major change to the infrastructure or procedures, or whenever any new threats are identified through risk monitoring activities. Further, unused or unwanted features of the platform shall be closely controlled to minimise risk.
The bank shall develop sound internal control systems and take into account the operational risk before offering digital payment products and related services. This shall include ensuring adequate safeguards to protect integrity of data, customer confidentiality, and security of data.
The bank shall ensure that its digital payment architecture is robust and scalable, commensurate with the transaction volumes and customer growth.

The bank shall adopt internationally accepted and published standards that are not deprecated / demonstrated to be insecure / vulnerable and shall ensure that the configurations involved in implementing such controls are compliant with extant laws and regulatory instructions.
The bank shall renew its digital certificates used in the digital payment ecosystem well in time.
The mobile application (mobile banking / mobile payment applications of the bank) and internet banking application shall have effective logging and monitoring capabilities to track user activity, security changes, and identify anomalous behaviour and transactions.

C. Application Security Life Cycle

The bank shall implement multi-tier application architecture, segregating application, database and presentation layer in the digital payment products and services.
The bank shall follow a ‘secure by design’ approach in the development of digital payment products and services. The bank shall ensure that digital payment applications are inherently more secure by embedding security within their development lifecycle.
The bank shall explicitly define security objectives (including protection of customer information / data) during

(1) requirements gathering;

(2) designing;

(3) development;

(4) testing including source code review;

(5) implementation, maintenance, and monitoring; and

(6) decommissioning phases of the digital payment applications.

The bank (including those partnering with other entities to co-brand / co-develop applications) shall adopt and incorporate a threat modelling approach during application lifecycle management into its policies, processes, guidelines, and procedures.
For digital payment applications licensed by a third-party vendor, the bank shall put in place a source code escrow arrangement or other arrangements for ensuring continuity of services in case the vendor defaults or is unable to provide services.
The bank shall conduct security testing including review of source code, Vulnerability Assessment (VA) and Penetration Testing (PT) of its digital payment applications to assure that the application is secure for putting through transactions while preserving confidentiality and integrity of the data that is stored and transmitted. Such testing shall invariably cover compliance with various standards like Open Worldwide Application Security Project (OWASP). In those cases, where the source code is not owned by the bank, the bank shall obtain a certificate from the application developer stating that the application is free of known vulnerabilities, malware, and any covert channels in the code. Further, the bank shall ensure the following:

(1) The VA shall be conducted at least on a half-yearly basis; PT shall be conducted at least annually. In addition, VA / PT shall be conducted as and when any new IT infrastructure or digital payment application is introduced or when any major change is performed in the application or infrastructure.

(2) Testing related to review of source code / certification shall be conducted / obtained and shall be continued annually, if changes / upgrades have been made to the application during the year.

(3) Testing / Certification shall address the objective that the product / version / module(s) functions only in a manner that it is intended for, is developed as per the best secure design / coding practices and standards, addressing known flaws / threats due to insecure coding.

(4) Penal provisions are included in third-party contractual arrangements for any non-compliance by the application provider.

The bank may also run automated VA scanning tools on a continuous / more frequent basis to automatically scan all systems on the network that are critical, public facing or store customer sensitive data.
The bank shall compare the results from earlier vulnerability scans to verify / ascertain that vulnerabilities are addressed either by patching, implementing a compensating control, or documenting and accepting the residual risk with necessary approval and that there is no recurrence of the known vulnerabilities. The identified vulnerabilities shall be fixed in a time-bound manner.
The bank shall ensure that vulnerability scanning is performed in authenticated mode either with agents running locally on the system to analyse the security configuration or with remote scanners that are given administrative rights on the system being tested.
The bank shall verify and thoroughly test the functionality (to validate whether the system meets the functional requirements / specifications) and security controls of payment products and services before their launch / moving to the production environment.
The bank shall institute a mechanism to actively monitor for non-genuine / unauthorised / malicious applications (with similar name / features) on popular app-stores and the web and respond appropriately to bring them down.
The server at the bank’s end shall have adequate checks and balances to ensure that no transaction is carried out through non-genuine / unauthorised digital payment products / applications and the authentication process is robust, secure, and centralised.
The security controls for digital payment applications shall focus on how these applications handle, store, and protect payment data. The Application Programming Interfaces (APIs) for secure data storage and communication shall be implemented and used correctly in order to be effective. The bank shall refer to standards such as OWASP-Mobile Application Security Verification Standard (OWASP-MASVS), OWASP-Application Security Verification Standard (OWASP-ASVS), and other relevant OWASP standards, security and data protection guidelines in ISO 12812, threat catalogues and guides developed by National Institute of Standards and Technology (NIST) (including for Bluetooth and Long-Term Evolution (LTE) security), for application security, and other protection measures. Such testing shall necessarily verify for vulnerabilities including but not limited to OWASP / OWASP Mobile Top 10, application security guidelines / requirements developed / shared by operating system providers / Original Equipment Manufacturers (OEMs).
The bank shall redact / mask customer information such as account numbers / card numbers / other sensitive information when transmitted via SMS / emails (including attachments).

D. Authentication Framework

The bank shall implement, except where explicitly permitted / relaxed, multi-factor authentication for payments through electronic modes and fund transfers, including cash withdrawals from ATMs / micro-ATMs / business correspondents, through digital payment applications. At least one of the authentication methodologies shall be dynamic or non-replicable. [e.g., Use of OTP, mobile devices (device binding and Subscriber Identification Module (SIM)), biometric / Public Key Infrastructure (PKI) / hardware tokens, ‘Europay, Mastercard, and Visa’ (EMV) chip card (for Card Present Transactions) with server-side verification could be termed either in dynamic or non-replicable methodologies].
The bank shall ensure to design and implement robust multi-factor authentication methods to:

(1) act as a strong fraud deterrent;

(2) be more difficult to compromise;

(3) protect the confidentiality of payment data; and

(4) enhance confidence in digital payment by effectively addressing various cyber-attack mechanisms like phishing, keylogging, spyware / malware, and other internet-based frauds targeted at the bank and its customers.

The bank may also adopt adaptive authentication to select the right authentication factors depending on risk assessment, user risk profile, and behaviour.
The implementation of appropriate authentication methods shall be based on an assessment of the risks posed by the bank’s digital payment products and services. The risks shall be evaluated in light of the type of customer (e.g., retail / corporate / commercial), the customer transactional requirements / pattern (e.g., bill payment, fund transfer), the sensitivity of customer information and the volume, value of transactions involved.
The authentication methods shall take into consideration, inter alia, customer acceptance, ease of use, reliable performance, scalability to accommodate growth, customer profile, location, transaction, and interoperability with other systems.
The bank shall implement multi factor authentication and alerts (through channels such as SMS and email) for all payment transactions (including debits and credits), creation of new account linkages (addition / modification / deletion of beneficiaries), change in account details or revision to fund transfer limits. In devising these security features, the bank shall take into account their efficacy and differing customer preferences for additional online protection.
The alerts and OTPs received by the customer for online transactions shall identify the merchant name, wherever applicable, rather than the payment aggregator through which the transaction was effected.
As an integral part of the multi factor authentication architecture, the bank shall also implement appropriate measures to minimise exposure to middleman attack which is more commonly known as a man-in-the-middle attack (MITM), man-in-the browser (MITB) attack or man-in-the application attack. The bank shall, inter alia, ensure, that the data in transit is secured and the transactions are authenticated only by genuine / authorised source / process.
The bank shall ensure that an authenticated session, together with its encryption protocol, shall remain intact throughout the interaction with the customer. In the event of interference or in case of closure of the application by the customer, the session shall be terminated, and the affected transactions shall be resolved or reversed out. The customer shall be promptly notified about the status of the transaction by email, SMS, or other means.
The bank shall set down the maximum number of failed login or authentication attempts after which access to the digital payment product / service is blocked.
The bank shall have a secure procedure in place to re-activate the access to blocked product / service. The bank shall notify the customer of failed login or authentication attempts.
