In 2018, about 106 million people participated in employer-sponsored defined contribution retirement plans, such as 401(k) plans. Assets in these plans were worth about $6.3 trillion.
A host of plan administrators share the personal information used to administer these plans via the internet, which can lead to significant cybersecurity risks. In some cases, there is no federal guidance about how to mitigate these risks.
The Department of Labor hasn't clarified whether plan administrators are responsible for mitigating cybersecurity risks and hasn’t set minimum expectations for protecting personal information. We recommended that the DOL do so.
What GAO Found
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.
Why GAO Did This Study
Cyber attacks against information systems (IT) are perpetuated by individuals or groups with malicious intentions, from stealing identities to appropriating money from accounts. DC plans, which allow individuals to accumulate tax-advantaged retirement savings, increasingly rely on the internet and IT systems for their administration. Accordingly, the need to secure these systems has become paramount. Ineffective data security controls can result in significant risks to plan data and assets. In 2018, DC plans enrolled 106 million participants and held nearly $6.3 trillion in assets, according to DOL.
This report examines (1) the data that sponsors and providers exchange during the administration of DC plans and their associated cybersecurity risks, and (2) efforts to assist sponsors and providers to mitigate cybersecurity risks during the administration of DC plans. GAO interviewed key entities involved with DC plans, such as sponsors and record keepers, DOL officials and industry stakeholders; and reviewed relevant federal laws, regulations, and guidance.
GAO is making two recommendations to DOL to formally state whether it is a fiduciary's responsibility to mitigate cybersecurity risks in DC plans and to establish minimum expectations for addressing cybersecurity risks in DC plans. DOL agreed with GAO's second recommendation but did not state whether it agreed or disagreed with the first one. GAO believes both recommendations are warranted.
Recommendations for Executive Action
|Department of Labor||1. The Secretary of Labor should formally state whether cybersecurity for private sector employer-sponsored defined contribution retirement plans is a plan fiduciary responsibility under ERISA. (Recommendation 1)|
|Department of Labor||2. The Secretary of Labor should develop and issue guidance that identifies minimum expectations for mitigating cybersecurity risks that outline the specific requirements that should be taken by all entities involved in administering private sector employer-sponsored defined contribution retirement plans. (Recommendation 2)|
