Due to the quick advancement of computer technology, the relevance of information has increased significantly for the banking sector. Protecting information security has consequently become a top priority for all banks. To solve this problem, we provide a unique strategy that extends an outranking technique named "ELiminating Et Choice Translating REality (ELECTRE)" in the context of a spherical cubic fuzzy (SCF) environment. Our suggested SCF-ELECTRE-I technique uses concordance and discordance sets, and a directed decision graph is used to offer the best option. Hence, based on score and accuracy levels, we establish three types of concordance and discordance sets: weak, medium, and strong. We intend to provide a multi-criteria group decision-making (MCGDM) strategy for evaluating online banking security concerns by combining these sets. We investigate the application of our suggested method and conduct a comparison with a few existing symmetrical approaches in order to confirm its validity and dependability.
