Common Challenges in Managing Digital Evidence

Organizations handling digital evidence face multiple operational challenges that can slow investigations and increase legal and security risks. Securing sensitive files, meeting regulatory requirements, and retrieving evidence quickly are among the most common obstacles.

Without the right technology, protecting data, maintaining compliance, and staying organized becomes increasingly difficult, often leading to inefficiencies and errors. In this section, we highlight the key challenges agencies face and how Digital Evidence Management System (DEMS) features help address them.

Scattered Data Storage and Retrieval Difficulties

One major challenge is fragmented digital evidence storage. When evidence is spread across multiple systems or locations, it increases the risk of loss, delays investigations, and disrupts case management.

As digital evidence volumes grow, locating specific files by date, type, or keywords becomes time-consuming. Traditional search methods are often slow and inefficient, making timely evidence retrieval difficult.

Inefficient Case Management

Managing multiple cases simultaneously makes it difficult to track digital evidence throughout its lifecycle. Without proper case management tools, agencies may lose visibility into where evidence is stored, who accessed it, or whether it is linked to the correct case.

This lack of oversight can result in errors, workflow disruptions, and delays, making it harder to ensure that critical evidence is available when needed.

Inability to Meet Compliance Standards

Meeting legal and regulatory standards such as CJIS is a significant challenge in digital evidence management. These regulations impose strict requirements for evidence storage, access, and retention, and non-compliance can lead to severe penalties.

Organizations may also need to comply with additional standards such as HIPAA or GDPR, each with specific security and retention requirements. Failing to meet these obligations can result in legal consequences and the exclusion of evidence in court.

Difficulties in Ensuring Evidence Integrity and Admissibility

Maintaining evidence integrity and admissibility requires a clear and verifiable chain of custody. Without proper tools, tracking how evidence is handled and transferred becomes difficult.

If evidence handling cannot be verified, its admissibility in court may be challenged, potentially undermining investigations and legal outcomes.

Unauthorized Access to Sensitive Evidence

Security remains a critical concern in digital evidence management. Unauthorized access to sensitive data can compromise investigations and lead to serious legal consequences.

Ensuring that only authorized personnel can access evidence, and that any suspicious activity is detected quickly, is essential to maintaining evidence security and integrity.

Insecure Evidence Sharing

Sharing digital evidence with external parties such as partner agencies or legal teams introduces additional risks. If evidence is not shared securely, it may be tampered with, compromised, or lost.

Insecure evidence sharing can result in data breaches, loss of credibility, and legal implications, affecting the overall integrity of investigations.

Limited Deployment Options

Organizations have varying requirements for deploying digital evidence management solutions. Challenges arise when suitable deployment options are limited.

While cloud-based solutions offer scalability and accessibility, on-premises deployments provide greater control and compliance. Limited deployment flexibility can create difficulties for organizations with strict regulatory, resource, or data residency requirements.

Chain of Custody Management

You need a system that tracks every action on evidence, providing a transparent, verifiable audit trail to prove authenticity.

A robust Digital Evidence Management System manages the evidence lifecycle by maintaining a detailed chain of custody and recording every action on digital evidence. This is documented in a detailed chain of custody, which tracks all actions, access, modifications, and sharing. This creates a transparent and verifiable audit trail that can be reviewed at any time to confirm the integrity of the evidence.

This comprehensive audit trail records every step in handling the evidence, providing you with a clear and unbroken record of events.

Security and Access Control

When it comes to security and access control, several key considerations must be taken into account. All of them are important to make sure data is kept secure. Otherwise, the risks can be devastating.

A significant breach in May 2022 exposed a vulnerability in the management of access to sensitive law enforcement data.

Hackers obtained a username and password for the DEA's Law Enforcement Inquiry and Alerts (LEIA) system, giving them access to highly classified information, including records on vehicles, firearms, and other tracked assets.

This breach enabled unauthorized access to sensitive data and posed a risk of tampering with records, potentially inserting false information into law enforcement databases.

This incident highlights the crucial need for robust Digital Evidence Management System (DEMS) security measures. Without stringent access controls and tamper detection, sensitive evidence can be compromised, jeopardizing investigations and leading to severe legal and operational consequences.

Here’s what to look for in Digital Evidence Management Systems (DEMS) when it comes to security:

Role-Based Access Control

One of the most significant risks with digital evidence is unauthorized access. Without proper controls, digital evidence could fall into the wrong hands, leading to data breaches, tampering, or leaks.

Role-based access Control solves this problem by restricting access to evidence based on user roles. By assigning permissions according to each user’s responsibilities, you ensure that only authorized personnel can view, modify, or share specific files.

Tamper Detection

The authenticity and integrity of digital evidence are crucial, especially in legal proceedings. Any sign of tampering can render evidence inadmissible. Tamper detection addresses this challenge by providing a clear audit trail of any changes or attempts to alter the evidence.

These mechanisms alert you to unauthorized modifications, ensuring the evidence remains intact and legally defensible.

Single Sign-On (SSO)

Single Sign-On (SSO) enables users to access the DEMS using a single set of secure credentials. This simplifies the login process and reduces the risk of credential theft, as users don’t need to remember or store multiple passwords.

SSO makes access more accessible and secure, ensuring that the right people can gain entry without compromising security.

IP and Geo-Restrictions

When digital evidence is accessed from multiple locations, there’s a risk that unauthorized users could gain access from outside approved areas. IP and geographical restrictions limit access based on specific IP addresses or geographic regions.

This means you can control where your evidence is accessed, ensuring that only trusted locations are allowed.

Real-Time Activity Alerts

One of the biggest challenges in managing digital evidence is staying ahead of potential security threats as they emerge. Real-time activity alerts address this by notifying you immediately of any suspicious behavior, such as unauthorized access attempts or unusual activity.

Evidence Sharing

It's crucial to share digital evidence securely and efficiently in modern investigations, especially when multiple parties are involved. The ability to securely and efficiently share evidence is vital.

A DEMS should provide robust features for sharing evidence both internally and externally, ensuring that the right people have access to the information they need. This can help make the process smoother while also ensuring that the evidence remains secure and confidential.

URL Tokenization

URL tokenization can be a powerful tool when you need to share evidence with external parties. This feature generates a unique URL that only authorized recipients can access. This link can be further secured with view or time limits to prevent access beyond the defined scope.

For instance, a law enforcement officer may provide a tokenized URL of evidence to a legal professional but set a time limit for the duration of the case. Once the time limit is up, the evidence will no longer be accessible.

Partner Agency Portals

Sometimes, law enforcement agencies have to collaborate with cross-border agencies. Seamless integration with partner agencies is crucial when conducting these collaborative investigations.

In this case, it's essential to provide access to evidence files, but ensure that the sharing doesn't exceed the desired scope. This is where digital evidence management systems can give access to separate portals to different agencies.

That way, they can only access the evidence shared with them, but not the entire collection.

This feature allows different organizations to securely share evidence across platforms, ensuring authorized personnel can access what they need without compromising security.

Flexible Deployment Options

Every organization has unique needs when it comes to managing digital evidence. Some might prioritize control and customization, while others need scalability and accessibility.

Therefore, a robust DEMS solution must provide flexible deployment options, such as SaaS, on-premises, on-cloud, or hybrid deployment. This flexibility enables organizations to select the configuration that best aligns with their operational objectives and security requirements.

If your organization requires maximum control over its data, an on-premises solution is often the best choice. By keeping the entire system within your IT infrastructure, you can implement customized security measures and ensure compliance with specific regulatory requirements.

This model is advantageous if you handle sensitive information or operate under strict legal constraints.

Cloud-based solutions are ideal for organizations seeking scalability and ease of access. With cloud deployment, you can quickly scale your storage and computing resources as needed without worrying about maintaining physical hardware.

To learn more about this, you can read our blog on cloud vs. physical evidence storage for digital evidence.

For those who need a balance between control and scalability, a hybrid solution combines the best of both worlds. Hybrid deployments allow you to keep sensitive data on-premises while leveraging the cloud for less critical operations or scaling purposes.

This approach offers flexibility and security, protecting the most sensitive evidence within the organization’s infrastructure while leveraging the cloud's scalability and convenience.
