Looking at Security Investment Amounts of the Four Major Banks... KB Citizens Bank Leads

According to data from the Korea Internet & Security Agency (KISA)'s information security disclosure portal, KB Citizens Bank invested the most in information security last year among the four major retail banks (KB Citizens, Shinhan, Hanara, Woori), allocating 433.2011 billion won. KB Citizens Bank was the only bank among the four to increase its investment by 1.9% compared to the previous year, while the other three banks saw decreases. NH Nonghyup Bank was excluded from the analysis as it is not legally required to disclose information security data. KB Citizens Bank's information security investment accounted for 8.2% of its IT spending, ranking third among the four banks. It also maintained 96.7 dedicated security personnel and a 5.1% security-to-IT workforce ratio. Although KB Citizens Bank invested the most in information security, its human resource allocation ranked lower. Hanara Bank followed with 371.6715 billion won in investments, but its security personnel count (71.9) was the lowest among the analyzed banks. Shinhan Bank maintained similar investment levels as the previous year at 368.9841 billion won, while Woori Bank reduced its investment by 18% year-over-year despite having the highest security personnel and investment ratio among the four banks.
