Cracking down on repeated non-compliance of IT norms, the RBI on Wednesday barred Kotak Mahindra Bank from onboarding new customers through its online and mobile banking channels and issuing fresh credit cards with immediate effect after the regulator found "serious deficiencies" in the lender's IT risk management.
These actions, the RBI said, are necessitated based on significant concerns arising out of Reserve Bank's IT examination of the bank for the years 2022 and 2023 and the continued failure on part of the bank to address these concerns in a comprehensive and timely manner.
Meanwhile, Kotak Mahindra Bank said in a statement that it has taken measures for adoption of new technologies to strengthen its IT systems and will continue to work with RBI to swiftly resolve balance issues at the earliest.
In a statement regarding the supervisory action against Kotak Mahindra Bank, the RBI said: "Serious deficiencies and non-compliances were observed in the areas of IT inventory management, patch and change management, user access management, vendor risk management, data security and data leak prevention strategy, business continuity and disaster recovery rigour and drill, etc." Kotak Mahindra Bank has been directed "to cease and desist", with immediate effect, from onboarding of new customers through its online and mobile banking channels and issuing fresh credit cards.
"The bank shall, however, continue to provide services to its existing customers, including its credit card customers," RBI said.
