How to Prevent Your First AI Data Breach

Learn why the broad use of gen AI copilots will inevitably increase data breaches

This scenario is becoming increasingly common in the gen AI era: a competitor somehow gains access to sensitive account information and uses that data to target the organization's customers with ad campaigns.

The organization had no idea how the data was obtained. It was a security nightmare that could jeopardize their customers' confidence and trust.

The company identified the source of the data breach: a former employee used a gen AI copilot to access an internal database full of account data. They copied sensitive details, like customer spend and products purchased, and took them to a competitor.

This example highlights a growing problem: the broad use of gen AI copilots will inevitably increase data breaches.

According to a recent Gartner survey, the most common AI use cases include generative AI-based applications, like Microsoft 365 Copilot and Salesforce's Einstein Copilot. While these tools are an excellent way for organizations to increase productivity, they also create significant data security challenges.

In this article, we'll explore these challenges and show you how to secure your data in the era of gen AI.

Gen AI's data risk 

Nearly 99% of permissions are unused, and more than half of those permissions are high-risk. Unused and overly permissive data access is always an issue for data security, but gen AI throws fuel on the fire.

When a user asks a gen AI copilot a question, the tool formulates a natural-language answer based on internet and business content via graph technology.

Because users often have overly permissive data access, the copilot can easily surface sensitive data — even if the user didn't realize they could access it.

Many organizations don't know what sensitive data they have in the first place, and right-sizing access is nearly impossible to do manually.

Gen AI lowers the bar on data breaches  

Threat actors no longer need to know how to hack a system or understand the ins and outs of your environment. They can simply ask a copilot for sensitive information or credentials that allow them to move laterally.

Security challenges that come with enabling gen AI tools include:

• Employees have access to far too much data 
• Sensitive data is often not labeled or is mislabeled 
• Insiders can quickly find and exfiltrate data using natural language 
• Attackers can discover secrets for privilege escalation and lateral movement 
• Right-sizing access is impossible to do manually 
• Generative AI can create new sensitive data rapidly

These data security challenges aren't new, but they are highly exploitable, given the speed and ease at which gen AI surfaces information.

How to stop your first AI breach

The first step in removing the risks associated with gen AI is to ensure that your house is in order.

It's a bad idea to let copilots loose in your organization if you're not confident that you know where you have sensitive data, what that sensitive data is, cannot analyze exposure and risks, and cannot close security gaps and fix misconfigurations efficiently.

Once you have a handle on data security in your environment and the right processes are in place, you are ready to roll out a copilot.

At this point, you should focus on permissions, labels, and human activity.

• Permissions: Ensure that your users' permissions are right-sized and that the copilot's access reflects those permissions.
• Labels: Once you understand what sensitive data you have and what that sensitive data is, you can apply labels to it to enforce DLP.
• Human activity: It is essential to monitor how employees use the copilot and review any suspicious behavior that's detected. Monitoring prompts and the files users access is crucial to prevent exploited copilots.

Incorporating these three data security areas isn't easy and can't be accomplished with manual effort alone. Few organizations can safely adopt gen AI copilots without a holistic approach to data security and specific controls for the copilots themselves.
