The transition of client services online and the shift to remote work by banks demand a reassessment of information and cybersecurity. Even minor security incidents can cost financial institutions reputation and business loss. Essential protective measures include continuous security level evaluation, penetration testing, and cybersecurity risk assessment. Ongoing training for users and administrators focuses on reducing the impact of the "human factor." Monitoring events, incident response, and behavioral analysis are crucial amid the rising cyber threat landscape. Machine learning, secure endpoints, and server management enhance transaction security.
