What this law does
The Central Bank of Nigeria issued the Regulatory Framework for the Use of Unstructured Supplementary Service Data for Financial Services in Nigeria in exercise of the powers conferred on it by section 47(2) of the CBN Act, 2007. The Framework lists banks, other financial institutions and payment service providers among the service providers that provide financial services through the use of USSD.
Section 6.1 of the Framework requires a financial institution providing use of the USSD channel to put in place a message authentication mechanism that validates that requests and responses are generated through authenticated users. Section 6.2 of the Framework requires the institution to ensure that the customer receives notification on the status of every transaction conducted through the channel.
Section 6.4 of the Framework requires the institution to ensure encryption of USSD information within its environment by an auditable process. Section 6.7 of the Framework requires the data stored by the USSD application at a financial institution to be encrypted. Section 6.7 of the Framework provides that customer information logged by the USSD application as part of financial transactions should not include sensitive information such as the customer PIN.
Section 6.10 of the Framework requires the institution to mandate the use of an effective second factor authentication by customers for all transactions above N20,000, in addition to the PIN. Section 6.11 of the Framework requires that the second factor not be sent to the customer's registered GSM number or device and not be generated or displayed on the USSD menu.
Section 6.12 of the Framework requires the institution to install a behavioural monitoring system with capability to detect SIM-swap or churn status, user location and unusual transactions at weekends. Section 10 of the Framework provides that the appropriate regulator, the CBN or the NCC as applicable, shall impose appropriate sanctions for any contravention on any participant that fails to comply with the Framework.
Section 47(3) of the Central Bank of Nigeria (Establishment) Act, 2007 gives the Bank power to prescribe rules and regulations for the efficient operation of all clearing and settlement systems.
