Introduction

Digital evidence systems contain some of the most sensitive information handled by public safety agencies. Body-Worn Camera (BWC) footage, interview recordings, photographs, case files, surveillance video, and other digital evidence may be accessed by officers, investigators, supervisors, evidence technicians, prosecutors, administrators, and authorized external partners.

As evidence repositories grow and agencies adopt cloud-based technologies, controlling who can access evidence, what they can access, and what they can do with it becomes increasingly important. A compromised account or excessive user permissions can create security, privacy, and operational risks.

Identity and Access Management (IAM) provides a framework for managing digital identities and controlling access to evidence systems. When combined with a modern Digital Evidence Management System (DEMS), IAM practices such as Multi-Factor Authentication (MFA), Role-Based Access Control (RBAC), least-privilege permissions, audit logging, and regular access reviews can help agencies strengthen security while maintaining efficient evidence workflows.

What Is Identity and Access Management?

Identity and Access Management refers to the policies, technologies, and processes organizations use to identify users and control their access to systems and information.

For digital evidence environments, IAM helps answer several important questions:

• Who is attempting to access the system?
• Has the user's identity been verified?
• What evidence is the user authorized to access?
• What actions can the user perform?
• Should the user still have access?
• Is the user's activity being recorded?

Effective IAM helps ensure that authorized users receive appropriate access while reducing unnecessary exposure of sensitive evidence.

Why IAM Matters for Digital Evidence

Digital evidence can contain confidential investigative information, personally identifiable information, and other sensitive data.

Weak access controls may increase the risk of:

• Unauthorized evidence access
• Inappropriate sharing
• Compromised accounts
• Accidental changes
• Privacy violations
• Insider threats

IAM provides a structured way to manage access across the organization.

Rather than giving broad permissions to every user, agencies can assign access according to specific operational responsibilities.

Implement Multi-Factor Authentication

Passwords can be stolen, guessed, reused, or exposed through phishing attacks.

Multi-Factor Authentication (MFA) adds another layer of identity verification before a user can access an evidence system.

Depending on the environment, authentication methods may include:

• Passwords
• Authentication applications
• Security tokens
• Hardware-based credentials
• Biometrics

MFA helps reduce the risk that a stolen password alone will provide unauthorized access to sensitive evidence.

Agencies should pay particular attention to accounts with administrative or other elevated privileges.

Use Role-Based Access Control

Not every user needs the same level of access.

Role-Based Access Control (RBAC) allows permissions to be assigned according to responsibilities rather than providing broad access across an entire evidence repository.

Roles might include:

• Patrol officers
• Detectives
• Supervisors
• Evidence technicians
• Prosecutors
• System administrators

For example, an officer may need access to evidence associated with their cases, while an evidence administrator may require broader management capabilities.

Properly designed roles make permissions easier to manage while strengthening security.

Follow the Principle of Least Privilege

The principle of least privilege means users should receive only the permissions necessary to perform their responsibilities.

Agencies can apply least privilege by:

• Limiting access to relevant cases
• Restricting administrative privileges
• Controlling download permissions
• Limiting evidence deletion capabilities
• Separating sensitive administrative functions

Reducing unnecessary privileges can limit the impact of compromised accounts, accidental actions, and inappropriate access.

Permissions should be based on operational need rather than convenience.

Manage Privileged Accounts Carefully

Administrative accounts can perform sensitive actions and therefore require additional protection.

Agencies should consider:

• Strong authentication requirements
• Separate administrator accounts where appropriate
• Limited assignment of administrative privileges
• Detailed activity logging
• Regular privilege reviews

Privileged accounts should not be treated like ordinary user accounts.

The greater the authority associated with an account, the stronger the controls surrounding it should be.

Automate User Provisioning and Deprovisioning

Access requirements change as personnel join an agency, change roles, transfer departments, or leave the organization.

Agencies need reliable procedures for:

• Creating new accounts
• Assigning appropriate permissions
• Updating access after role changes
• Suspending inactive accounts
• Removing access promptly when personnel leave

Integrating IAM with organizational identity systems can help automate portions of this process.

Promptly removing unnecessary access reduces the risk of outdated accounts remaining active.

Conduct Regular Access Reviews

Permissions that were appropriate when originally assigned may no longer be necessary months or years later.

Agencies should periodically review:

• Active user accounts
• Administrative privileges
• Role assignments
• External user access
• Inactive accounts
• Unusual permission combinations

Access reviews allow agencies to identify unnecessary privileges and adjust them before they create security problems.

IAM should be continuously maintained rather than configured once and forgotten.

Maintain Detailed Audit Trails

A secure evidence system should provide visibility into user activity.

Audit trails may record:

• Successful and failed login attempts
• Evidence views
• Downloads
• Sharing activity
• Permission changes
• Administrative actions
• Other significant evidence activity

These records can support accountability, security investigations, and chain-of-custody documentation.

Automated audit logging also makes it easier to identify unusual or unauthorized behavior.

Secure Remote Evidence Access

Cloud-based evidence platforms may allow authorized personnel to access evidence outside traditional agency facilities.

Remote access should include appropriate protections such as:

• Multi-Factor Authentication
• Secure encrypted connections
• Device security
• Session controls
• Role-based permissions
• Activity logging

Agencies should determine which users actually require remote access rather than enabling it broadly.

Remote accessibility should increase operational flexibility without weakening security.

Control External and Multi-Agency Access

Evidence may need to be shared with prosecutors, courts, neighboring departments, task forces, or other authorized organizations.

External access should be carefully controlled through measures such as:

• Case-specific permissions
• Time-limited access
• Expiration controls
• Download restrictions
• Authentication requirements
• Activity logging

Agencies should also establish procedures for removing external access when collaboration ends.

Secure sharing provides partners with the information they need without unnecessarily opening the entire evidence environment.

Integrate IAM Across Public Safety Systems

Modern agencies often operate interconnected technology environments.

Identity management may extend across:

• Digital Evidence Management Systems
• Records Management Systems (RMS)
• Computer-Aided Dispatch (CAD)
• Body-Worn Camera platforms
• In-car video systems
• Command center applications

Centralized identity services and capabilities such as Single Sign-On (SSO) can simplify authentication while allowing agencies to apply more consistent security policies across systems.

Integration can also reduce the administrative burden of managing separate credentials.

Monitor for Suspicious Account Activity

IAM should help agencies identify unusual behavior rather than simply controlling initial access.

Potential warning signs can include:

• Repeated failed login attempts
• Access from unexpected locations
• Unusual download activity
• Sudden privilege changes
• Attempts to access unrelated evidence
• Activity from dormant accounts

Security monitoring can help administrators investigate suspicious activity before it develops into a larger incident.

Combining identity data with audit logs provides stronger visibility into the evidence environment.

Consider Zero Trust Principles

Traditional security models sometimes assume users or devices inside an organizational network can be trusted automatically.

A Zero Trust approach instead emphasizes continuous verification and limited access.

Core concepts may include:

• Verify users explicitly
• Limit privileges
• Evaluate device security
• Monitor activity continuously
• Assume credentials could be compromised

Zero Trust does not refer to a single product. It is a security approach that can help agencies design stronger identity and access controls.

Support Applicable CJIS Security Requirements

Agencies handling Criminal Justice Information should evaluate their IAM practices against the applicable FBI Criminal Justice Information Services (CJIS) Security Policy and other relevant requirements.

Identity-related areas may include:

• Authentication
• Account management
• Access control
• Audit logging
• Security awareness
• Remote access
• System monitoring

Because security requirements can change, agencies should consult the current CJIS Security Policy and appropriate security, legal, or compliance personnel when designing their IAM programs.

Train Users on Identity Security

IAM technology is most effective when users understand their responsibilities.

Training should address:

• Protecting credentials
• Recognizing phishing attempts
• Using MFA correctly
• Avoiding password sharing
• Reporting suspicious activity
• Following evidence access policies

Personnel should understand that their credentials represent their identity within the evidence system.

Protecting those credentials helps protect the evidence itself.

Best Practices for Evidence System IAM

Agencies building or improving an IAM strategy should consider these practices:

• Require strong authentication and MFA
• Implement role-based access controls
• Apply least-privilege principles
• Protect privileged accounts
• Automate identity lifecycle processes where appropriate
• Remove access promptly when no longer required
• Conduct regular access reviews
• Maintain detailed audit logs
• Monitor suspicious account activity
• Carefully manage external access
• Train personnel regularly
• Review security policies as technology and requirements evolve

The goal is to provide the right person with the right access to the right information at the right time—while maintaining accountability for that access.

Conclusion

Identity and Access Management is a fundamental component of digital evidence security. As agencies adopt cloud-based platforms, expand Body-Worn Camera programs, and collaborate with more external partners, controlling access becomes increasingly complex.

Strong IAM practices help agencies verify users, restrict unnecessary privileges, protect administrative accounts, manage access throughout the employee lifecycle, and maintain visibility into how digital evidence is being used. Multi-Factor Authentication, Role-Based Access Control, least privilege, detailed audit logging, and continuous access reviews provide important layers of protection.

By making identity security part of the broader digital evidence strategy, agencies can improve cybersecurity without creating unnecessary barriers for authorized personnel. Effective IAM helps keep sensitive evidence accessible to those who need it—and protected from those who do not.
