Cybersecurity Challenge in Nigeria Deposit Money Banks

The study investigates cybersecurity challenges in Nigerian deposit money banks (DMBs) with a focus on proactive measures taken by banks and customers to overcome these challenges. The research design employs a descriptive approach and census sampling, with data collected from staff of selected DMBs using questionnaires. Data analysis was conducted using SPSS, and findings indicate that the major challenges confronting cybersecurity in banks were pharming, identity theft, SIM Swap fraud, Skimming/Website cloning and Smishing/Vishing. The major factors responsible were found to include loopholes in the banks’ internal control system, insider abuse by bank staff, ignorance and lack of security consciousness among the banking customers etc. it was found that banks implement measures such as encryption, password changes, and blocking unsolicited messages to mitigate cybersecurity risks. The study concludes with recommendations for continuous security updates, internal control reviews, and customer education campaigns. While the study addresses an important topic, there are areas where clarity, depth, and methodological rigor could be strengthened for a more robust contribution to the field.
