How to Prevent Data Breaches in Healthcare and Protect PHI

In today’s hyper-connected world, where big data powers decision-making, artificial intelligence (AI) is transforming industries and user experiences around the globe. Yet, while AI technology brings exciting possibilities, it also raises pressing concerns, particularly related to security, compliance, and ethical integrity. 

As AI adoption accelerates一fueled by increasingly vast and unstructured data sources—organizations seeking to secure AI deployments (and investments) must establish a strong AI governance initiative with data governance at its core.

This article delves into the essentials of AI governance, outlines its importance, examines the challenges involved, and presents best practices to help companies implement a resilient, secure, and ethically sound AI governance framework centered around data.

What is AI Governance?

AI governance encompasses the frameworks, practices, and policies that guide the responsible, safe, and ethical use of AI systems across an organization. Effective AI governance integrates technical elements—data, models, and code—with human oversight for a holistic framework that evolves alongside an organization’s AI initiatives.

Embedding AI governance, along with related data security measures, into organizational practices not only guarantees responsible AI use but also long-term success in an increasingly AI-driven world.

With an AI governance structure rooted in secure data practices, your company can:

• Mitigate risks: Ongoing AI risk assessments can proactively identify and address potential threats, such as algorithmic bias, transparency gaps, and potential data leakage; this ensures fairer AI outcomes while minimizing reputational and regulatory risks tied to flawed or opaque AI systems.
• Ensure strict adherence: Effective AI governance and compliance policies create clear accountability structures, aligning AI deployments and data use with both internal guidelines and the broader regulatory landscape such as data privacy laws or industry-specific AI standards.
• Optimize AI performance: Centralized AI governance provides full visibility into your end-to-end AI deployments一from data sources and engineered feature sets to trained models and inference endpoints; this facilitates faster and more reliable AI innovations while reducing security vulnerabilities.
• Foster trust: Ethical AI governance practices, backed by strict data security, reinforce trust by ensuring AI systems are transparent and safe, which is crucial for building confidence among both internal and external stakeholders.

A robust AI governance framework means your organization can safeguard sensitive data, build trust, and responsibly harness AI’s transformative potential, all while maintaining a transparent and aligned approach to AI.

Why Data Governance Is at the Center of AI Governance

Data governance is key to effective AI governance because AI systems require high-quality, secure data to properly function. Accurate, complete, and consistent data is a must for AI performance and the decisions that guide it. Additionally, strong data governance enables organizations to navigate complex regulatory landscapes and mitigate ethical concerns related to bias.

Through a structured data governance framework, organizations can not only achieve compliance but also leverage data as a strategic asset, ultimately leading to more reliable and ethical AI outcomes.

Risks of Not Having a Data-Driven AI Governance Framework

AI systems are inherently complex, non-deterministic, and highly adaptive—characteristics that pose unique challenges for governance. 

Many organizations face difficulty blending AI governance with their existing data governance and IT protocols; however, a centralized approach to governance is necessary for comprehensive oversight. Without a data-centric AI governance framework, organizations face risks such as:

• Opaque decision-making: Without clear lineage and governance, it becomes difficult to trace and interpret AI decisions, which can lead to unethical, discriminatory, or harmful outcomes.
• Data breaches: AI systems rely on large volumes of data, making rigorous data security protocols essential to avoid leaks of sensitive information across an extended attack surface covering both model inputs and outputs. 
• Regulatory non-compliance: The fast-paced evolution of AI regulations means organizations without a governance framework risk large penalties for non-compliance and potential reputational damage.

Implementing AI Governance: A Balancing Act

While centralized, robust AI governance is crucial, implementing it successfully poses significant challenges. Organizations must find a balance between driving innovation and maintaining strict oversight of AI operations.

A primary issue is ensuring that governance processes are both adaptable enough to support AI innovation and stringent enough to uphold data security and regulatory compliance. This balance is difficult to achieve, particularly as AI regulations vary widely across jurisdictions and are frequently updated. 

Another key challenge is the demand for continuous monitoring and auditing. Effective governance requires real-time tracking of data usage, model behavior, and compliance adherence, which can add significant operational overhead if not managed carefully.

To address these challenges, organizations need an adaptive governance framework that prioritizes privacy, data security, and ethical responsibility, while also supporting operational efficiency and scalability.

Frameworks & Best Practices for Implementing Data-Driven AI Governance

While there is no universal model for AI governance, your organization can look to established frameworks, such as the AI Act or OECD AI Principles, to create a framework tailored to your own risk tolerance, industry regulations, AI use cases, and culture.

Below we explore key data-driven best practices—relevant across AI use cases—that can best help you structure an effective and secure data-centric AI governance framework.

Adopt a Lifecycle Approach

A lifecycle approach divides oversight into stages. Implementing governance at each stage of the AI lifecycle enables thorough oversight of projects from start to finish following a multi-layered security strategy. 

For example, in the development phase, teams can conduct data risk assessments, while ongoing performance monitoring ensures long-term alignment with governance policies and control over data drift.

Prioritize Data Security

Protecting sensitive data is foundational to responsible AI governance. Begin by achieving full visibility into data assets, categorize them by relevance, and then assign risk scores to prioritize security actions. 

An advanced data risk assessment combined with data detection and response (DDR) can help you streamline risk scoring and threat mitigation across your entire data catalog, ensuring a strong data security posture.

Adopt a Least Privilege Access Model

Restricting data access based on user roles and responsibilities limits unauthorized access and aligns with a zero-trust security approach. By ensuring that sensitive data is accessible only to those who need it for their work via least privilege, you reduce the risk of data breaches and enhance overall data security.

Establish Data Quality Monitoring

Ongoing data quality checks help maintain data integrity and accuracy, meaning AI systems will be trained on high-quality data sets and serve quality requests. 

Implement processes for continuous monitoring of data quality and regularly assess data integrity and accuracy; this will minimize risks associated with poor data quality and improve AI performance by keeping data aligned with governance standards.

Implement AI-Specific Detection and Response Mechanisms

Continuous monitoring of AI systems for anomalies in data patterns or performance is critical for detecting risks before they escalate. 

Anomaly detection for AI deployments can alert security teams in real time to unusual access patterns or shifts in model performance. Automated incident response protocols guarantee quick intervention, maintaining AI output integrity and protecting against potential threats.

A data security posture management (DSPM) tool allows you to incorporate continuous monitoring with minimum overhead to facilitate proactive risk management.

Conclusion

AI governance is essential for responsible, secure, and compliant AI deployments. By prioritizing data governance, organizations can effectively manage risks, enhance transparency, and align with ethical standards while maximizing the operational performance of AI.

As AI technology evolves, governance frameworks must be adaptive, ready to address advancements such as generative AI, and capable of complying with new regulations, like the UK GDPR.

As businesses accelerate their digital growth, the complexity of securing sensitive data in the cloud is growing just as fast. Data moves quickly and threats are evolving even faster; keeping cloud environments secure has become one of the biggest challenges for security teams today.

In The Hacker News’ webinar, Benny Bloch, CISO at Global-e, and David Stuart, Senior Director of Product Marketing at Sentra, discuss the challenges and solutions associated with Data Security Posture Management (DSPM) and how it's reshaping the way organizations approach data protection in the cloud.

The Shift from Traditional IT Environments to the Cloud

Benny highlights how the move from traditional IT environments to the cloud has dramatically changed the security landscape. 

"In the past, we knew the boundaries of our systems. We controlled the servers, firewalls, and databases," Benny explains. However, in the cloud, these boundaries no longer exist. Data is now stored on third-party servers, integrated with SaaS solutions, and constantly moved and copied by data scientists and developers. This interconnectedness creates security challenges, as it becomes difficult to control where data resides and how it is accessed. This transition has led many CISOs to feel a loss of control. 

As Benny points out, "When using a SaaS solution, the question becomes, is this part of your organization or not? And where do you draw the line in terms of responsibility and accountability?"

The Role of DSPM in Regaining Control

To address this challenge, organizations are turning to DSPM solutions. While Cloud Security Posture Management (CSPM) tools focus on identifying infrastructure misconfigurations and vulnerabilities, they don’t account for the movement and exposure of data across environments. DSPM, on the other hand, is designed to monitor sensitive data itself, regardless of where it resides in the cloud.

David Stuart emphasizes this difference: "CSPM focuses on your infrastructure. It’s great for monitoring cloud configurations, but DSPM tracks the movement and exposure of sensitive data. It ensures that security protections follow the data, wherever it goes."

For Benny, adopting a DSPM solution has been crucial in regaining a sense of control over data security. "Our primary goal is to protect data," he says. "While we have tools to monitor our infrastructure, it’s the data that we care most about. DSPM allows us to see where data moves, how it’s controlled, and where potential exposures lie."

Enhancing the Security Stack with DSPM

One of the biggest advantages of DSPM is its ability to complement existing security tools. For example, Benny points out that DSPM helps him make more informed decisions about where to prioritize resources. "I’m willing to take more risks in environments that don’t hold significant data. If a server has a vulnerability but isn’t connected to sensitive data, I know I have time to patch it."

By using DSPM, organizations can optimize their security stack, ensuring that data remains protected even as it moves across different environments. This level of visibility enables CISOs to focus on the most critical threats while mitigating risks to sensitive data.

A Smooth Integration with Minimal Disruption

Implementing new security tools can be a challenge, but Benny notes that the integration of Sentra’s DSPM solution was one of the smoothest experiences his team has had. "Sentra’s solution is non-intrusive. You provide account details, install a sentinel in your VPC, and you start seeing insights right away," he explains. Unlike other tools that require complex integrations, DSPM offers a connector-less architecture that reduces the need for ongoing maintenance and reconfiguration.

This ease of deployment allows security teams to focus on monitoring and securing data, rather than dealing with the technical challenges of integration.

The Future of Data Security with Sentra’s DSPM

As organizations continue to rely on cloud-based services, the need for comprehensive data security solutions will only grow. DSPM is emerging as a critical component of the security stack, offering the visibility and control that CISOs need to protect their most valuable assets: data.

By integrating DSPM with other security tools like CSPM, organizations can ensure that their cloud environments remain secure, even as data moves across borders and infrastructures. As Benny concludes, "You need an ecosystem of tools that complement each other. DSPM gives you the visibility you need to make informed decisions and protect your data, no matter where it resides."

This shift towards data-centric protection is the future of AI-era security, helping organizations stay ahead of threats and maintain control over their ever-expanding digital environments.
