Defined Contribution Plans: Federal Guidance Could Help Mitigate Cybersecurity Risks in 401(k) and Other Retirement Plans, GAO-21-25, Published: Feb 11, 2021. Publicly Released: Mar 15, 2021.
“In their role administering private sector employer-sponsored defined contribution (DC) retirement plans, such as 401(k) plans, plan sponsors and their service providers—record keepers, third party administrators, custodians, and payroll providers—share a variety of personally identifiable information (PII) and plan asset data among them to assist with carrying out their respective functions (see figure). The PII exchanged for DC plans typically include participant name, Social Security number, date of birth, address, username/password; plan asset data typically includes numbers for both retirement and bank accounts. The sharing and storing of this information can lead to significant cybersecurity risks for plan sponsors and their service providers, as well as plan participants. Data Sharing Among Plan Sponsors and Service Providers in Defined Contribution Plans – Federal requirements and industry guidance exist that could mitigate cybersecurity risks in DC plans, such as requirements that pertain to entities that directly engage in financial activities involving DC plans. However, not all entities involved in DC plans are considered to have such direct engagement, and other cybersecurity mitigation guidance is voluntary. Federal law nevertheless requires plan fiduciaries to act prudently when administering plans. However, the Department of Labor (DOL) has not clarified fiduciary responsibility for mitigating cybersecurity risks, even though 21 of 22 stakeholders GAO interviewed expressed the view that cybersecurity is a fiduciary duty. Further, DOL has not established minimum expectations for protecting PII and plan assets. DOL officials told GAO that the agency intends to issue guidance addressing cybersecurity-related issues, but they were unsure when it would be issued. Until DOL clarifies responsibilities for fiduciaries and provides minimum cybersecurity expectations, participants’ data and assets will remain at risk…”
