With Granular Access Control (GAC), law enforcement agencies can ensure that only authorized personnel have access to specific evidence and can perform designated actions such as viewing, editing, or sharing files. This level of control helps ensure that sensitive data is only accessible to those who need it, preventing unauthorized access and maintaining the integrity of the evidence.
Digital evidence obtained from surveillance cameras, dash cameras, and body-camera footage often contains highly sensitive information that should only be disclosed to authorized personnel.
But it's not just your local police department that sees this evidence. Sometimes, it's circulated with other federal agencies, such as the Federal Bureau of Investigation (FBI) and the Department of Homeland Security (DHS).
Post 9/11, information sharing between law enforcement agencies has become critical, especially when it concerns digital data. Whether it's to apprehend perpetrators in overlapping jurisdictions or protect national security interests at large, data sharing is not only useful but, oftentimes, mandated.
With all this sharing, there's a catch. Not everyone in the local, state, or federal departments should have access to such sensitive information. It needs to be restricted and limited to only specific personnel within such agencies.
Law enforcement departments are composed of investigators, intelligence agents, analysts, and evidence custodians who could come across this information. However, this information can only be shared with those that have the appropriate security clearance or ‘need to know’ and ‘need to share’ basis.
Not everyone needs the same level of access to digital evidence and sensitive case information. Investigators chase leads, analysts decipher patterns, and intel agents paint the big picture. Everyone has a role they need to fulfill.
Unauthorized access to information and leaked data exposes informants, stalls and hampers investigations, and can even unleash national security nightmares. Imagine compromise leads to an ongoing investigation, informants facing retribution, or classified documents slipping through the cracks.
All of that brings us to the problem of having an efficient way to share information while also ensuring that it is restricted from being shared with unauthorized personnel. Whether inter-agency evidence sharing or with external agencies across the United States, the need for an effective solution is evident.
Luckily, there is a solution: an evidence management system with secure and precise Granular Access Control (GAC). In this blog, we'll discuss what that is, how it works, and how it can help law enforcement share evidence with the right agencies.
Granular Access Control is a method of managing access to computer or network resources based on the specific permissions assigned to individual users, allowing agencies to control exactly who can access, modify, or manage pieces of evidence.
Unlike traditional role-based systems, which assign access based on broad roles, granular access control offers a more detailed level of security. For example, a patrol officer might have permission to view evidence related to their assigned cases but may not have access to modify or share it, while a lead investigator might have permissions to create, alter, and manage evidence within the investigation.
In the context of evidence management, granular access control ensures that only the right individuals can interact with evidence in specific ways. This means users can be granted access to certain files, allowed to view them, but restricted from making changes or exporting sensitive information, depending on their level of authorization.
Operating without a proper granular access control system can be especially dangerous for law enforcement. Unauthorized access or alterations to sensitive evidence can have dire legal and operational consequences, potentially compromising investigations or damaging the integrity of the case.
Law enforcement agencies consist of diverse personnel, each playing distinct roles to fulfill essential duties. These roles vary not just across the agency but also within specialized units or teams. Understanding these roles is key to managing and controlling access to digital evidence securely.
As law enforcement personnel handle data at various stages of an investigation, secure mechanisms for managing access and sharing are crucial. Without proper systems, data management can become chaotic, risking evidence mishandling. Granular access control ensures that each role has access only to the information necessary for their duties, maintaining the integrity of the investigation.
Telecommunicators, like 911 operators or non-emergency hotline responders, are the first to interact with victims or witnesses. They gather critical details about the crime and report them to responding officers. Granular access control ensures that sensitive data collected by telecommunicators is securely handled and only accessible to authorized personnel.
Patrol officers are typically the first on the scene, gathering statements from witnesses and securing the crime scene. They may compile initial reports based on victim and witness information. Granular access control ensures that only authorized officers can modify or share evidence, safeguarding it for further investigation.
Investigators take charge after the initial scene work, collaborating with officers and gathering additional evidence. They have access to sensitive data like witness statements and crime scene reports. Granular access control helps manage this access, ensuring investigators can view and work with necessary evidence while protecting it from unauthorized modifications.
Evidence technicians collect, document, and secure evidence, including photographs and crime scene diagrams. Granular access control allows them to manage sensitive data securely, ensuring only authorized personnel can alter or share evidence, thus maintaining the chain of custody.
By implementing granular access control for each role, law enforcement agencies can securely manage the flow of evidence, ensuring that only authorized personnel have access to the data they need. This enhances security, reduces risks, and improves operational efficiency.
Digital evidence is essential for solving cases and ensuring convictions, making its security and confidentiality critical. Granular access control ensures that only authorized personnel can access sensitive evidence, preventing breaches and unauthorized alterations.
Without proper access controls, law enforcement agencies risk compromising evidence and damaging confidentiality. Granular access control streamlines access, allowing officers to focus on their tasks, such as evidence collection and analysis, while IT administrators can manage access based on actual need.
Access needs differ across roles. For example, an evidence custodian might not need to view or edit evidence, while an investigator requires access to analyze it. Granular access control restricts access to the necessary functions only, preventing unauthorized actions and ensuring security. The 2022 breach of the LEIA system highlights the importance of limiting access, as stolen credentials led to widespread unauthorized access.
Collaborating across units or agencies is common in complex cases. Granular access control ensures stakeholders have the precise access they need without exposing sensitive data unnecessarily. Systems like RISS enable secure collaboration among agencies while maintaining data security and privacy.
Digital evidence is highly sensitive and vulnerable to cyberattacks. Granular access control ensures that only authorized personnel can handle or modify evidence, maintaining its integrity. This reduces the risk of data manipulation and ensures compliance with protocols to protect the evidence.
Unauthorized access or mishandling of evidence can undermine public trust in law enforcement. Granular access control limits who can access sensitive information, protecting both the integrity of the case and the reputation of the agency involved.
Law enforcement must comply with regulations like the CJIS Security Policy, which mandates strong access controls. Granular access control aligns with these requirements, ensuring that only authorized individuals can access sensitive data while maintaining compliance.
Digital evidence often contains personal information, making privacy a key concern. Granular access control ensures that only authorized personnel can access or modify sensitive data, protecting individual privacy and ensuring compliance with regional data protection laws.
Implementing granular access control within a law enforcement agency is a strategic process that integrates technology, organizational roles, and security measures to safeguard sensitive data.
Here are the steps for implementing granular access control:
The first step in implementing granular access control is understanding the roles within the agency. Each law enforcement role, from police officers to investigators to IT administrators, requires different levels of access to digital evidence. Identifying these roles and their specific needs helps determine who should have access to what information.
Once roles are defined, the next step is to determine the scope of access for each role. Each role will have specific permissions that dictate what actions can be performed on the evidence. For example, an evidence custodian might have the right to add evidence but not modify or delete it, while an investigator might have access to view and share evidence with relevant stakeholders. Granular access control ensures that everyone has access to the data they need to perform their duties without overexposure.
After defining roles and access scopes, permissions can be assigned to specific personnel. This task is typically managed by the IT administrator. By assigning precise permissions, agencies ensure that digital evidence is managed, accessed, and transferred securely, with each person granted access only to the relevant parts of the system necessary for their role.
Once granular access control is in place, it is essential to regularly monitor and review the system. IT administrators and compliance officers should review audit logs to ensure that access is in line with the defined roles and permissions. Any necessary changes or adjustments should be made after thorough evaluation to maintain a secure and efficient system.
