A Written Information Security Plan As An Important Tool for HR and Benefits Administration

HR and benefits departments manage some of an organization’s most sensitive information, including Social Security numbers, payroll records, health plan elections, dependent information, tax reporting data, direct deposit information, and employee medical information. As cyber threats continue to evolve, employers should take steps to ensure they have a documented approach to protecting that information.

The IRS recently highlighted the importance of maintaining a Written Information Security Plan (WISP). While the IRS guidance is directed toward tax professionals, the same principles apply to employers, HR departments, benefits administrators, payroll teams, and any organization that collects, stores, or transmits confidential employee information.

A WISP is a written document that outlines how an organization protects sensitive information, identifies risks, responds to security incidents, and continuously evaluates its security controls. The most effective plans are tailored to the organization’s size, complexity, technology environment, and the type of information it handles.

What Should a WISP Address?

According to IRS guidance, a strong information security program should focus on several core areas:

• Employee training and security awareness
• Protection of information systems and data
• Identification and management of security risks
• Detection and response to system failures and security incidents
• Ongoing testing and monitoring of security safeguards

Organizations should also designate one or more individuals responsible for overseeing the information security program, assessing risks, implementing safeguards, and monitoring compliance with security policies.

Key Security Areas HR Departments Should Evaluate

Although every organization is different, HR and benefits teams should consider whether their security program addresses the following areas:

Access Controls

Employee information should only be accessible to individuals with a legitimate business need. User accounts should be unique to each employee, permissions should be based on job responsibilities, and access rights should be reviewed periodically. Shared logins should be avoided whenever possible.

Password and Authentication Practices

Strong password requirements and multi-factor authentication (MFA) can significantly reduce the risk of unauthorized access. MFA is especially important for benefits administration platforms, payroll systems, email accounts, and remote access tools.

Employee Training

Many security incidents begin with phishing emails, fraudulent text messages, or social engineering attempts. Regular employee training can help staff identify suspicious communications and understand their responsibilities when handling confidential information.

Vendor Management

HR departments often rely on payroll providers, benefits administrators, enrollment platforms, COBRA administrators, brokers, consultants, and other service providers. Organizations should evaluate whether vendors maintain appropriate safeguards and understand how employee information is stored, processed, and transmitted.

Data Backup and Recovery

Security planning should include procedures for backing up important data and restoring systems following a cyber incident, ransomware attack, hardware failure, or natural disaster. Organizations should periodically test their backup and recovery processes to verify they function as intended.

Physical Security

Information security is not limited to electronic systems. Employers should consider how paper records, personnel files, benefit enrollment forms, and other physical documents are protected from unauthorized access.

Incident Response Planning

A WISP should outline how the organization will respond if a security incident occurs. This may include identifying key decision-makers, documenting notification procedures, preserving evidence, coordinating with vendors, and communicating with affected individuals when necessary.

Regular Reviews and Updates

One of the IRS’s key recommendations is that security plans should not remain static. Organizations should periodically review and update their WISP to account for changes in technology, staffing, business operations, and emerging threats. A plan developed several years ago may no longer adequately address today’s cybersecurity risks.

Questions HR Leaders Should Consider

As part of an annual review, HR and benefits professionals may want to ask:

• Do we have a documented Written Information Security Plan?
• Who is responsible for maintaining and updating it?
• Are employees receiving periodic security awareness training?
• Do we require multi-factor authentication for systems containing employee information?
• Have we evaluated the security practices of our payroll, benefits, and HR vendors?
• Do we have a documented incident response process?
• Have we tested our backup and recovery procedures?
• Are access rights reviewed when employees change roles or leave the organization?

The Bottom Line

Employee and benefits data remain attractive targets for cybercriminals. A Written Information Security Plan helps organizations establish a structured framework for protecting that information, reducing risk, and responding effectively when incidents occur. For HR and benefits professionals, a well-maintained WISP can serve as an important component of a broader privacy, security, and compliance strategy while helping safeguard the sensitive information employees entrust to their employer.
