  • Driver’s License Numbers

Lessons Learned

Below are suggested lessons learned from the Equifax breach that will help ensure your institution has the proper controls implemented that would reduce the likeliness your institution would be compromised from similar types of cyber-attacks.

  • External Penetration Testing – It is suspected that an externally facing web application was compromised in the Equifax breach. At a minimum, an annual penetration test should be done on externally facing systems to identify vulnerabilities and examine how they may be exploited. A component of this assessment must include a Web Application Assessment, to ensure the unique vulnerabilities in complex web applications are identified and tested.

  • Include Credit Bureaus in Vendor Management Program – If you are sending information to a credit bureau they should be included into your vendor management program. This will help encourage accountability in these relationships and demonstrates your efforts to protect the safety and soundness of your customer data.
     
  • Risk assess all critical applications, specifically externally facing web applications and open-source software. This will help ensure your systems have adequate controls in place to secure them at a level that meets your risk appetite. These controls could include independent testing, patch management, vendor management, encryption, and intrusion prevention.
