Protecting Your Business Bank Accounts: Lessons Learned

At Lexicon Bank, we prioritize the security of our clients’ accounts. Here are several strategies to protect your business from similar cybersecurity threats:

• Implement Strong Authentication Methods
  • Multi-Factor Authentication (MFA): Enhance account security by requiring multiple forms of verification, reducing the risk of unauthorized access.
  • Secure Password Policies: Encourage the use of complex, unique passwords and regular password updates to strengthen account protection.  In addition, never use the same password to log on to different systems. This will help reduce your exposure should a password be compromised.

  • Automated Patching Systems: Utilize automated systems to manage and deploy patches promptly, reducing the risk of human error.

• Comprehensive Employee Training
  • Cybersecurity Awareness: Conduct regular training sessions to keep employees informed about the latest cybersecurity threats and best practices.
  • Phishing Prevention: Educate employees on recognizing and avoiding phishing attempts, a common tactic cybercriminals use.

• Continuous Monitoring and Auditing

• • Real-Time Alerts: Set up alerts for unusual account activity, such as large transactions or login attempts from unfamiliar locations.
  • Routine Audits: Perform regular audits of account activities to identify and investigate any irregularities promptly.

• Advanced Security Tools
  • Data Encryption: Ensure that all sensitive data is encrypted both in transit and at rest, protecting it from unauthorized access.
