Access Controls that Move - The Power of Data Security Posture Management

Data Security

Controlling access to data has always been one of the basics of cybersecurity hygiene. Managing this access has evolved from basic access control lists, to an entire Identity and Access Management industry. IAM controls are great at managing access to applications, infrastructure and on-prem data. But cloud data is a trickier issue. Data in the cloud changes environments and is frequently copied, moved, and edited. 

This is where data access tools share the same weakness- what happens when the data moves? (Spoiler - the policy doesn’t follow).

The Different Access Management Models

There are 3 basic types of access controls enterprises use to control who can read and edit their data.

Access Control Lists: Basic lists of which users have read/write access.

Role Based Access Control (RBAC): The administrator defines access by what roles the user has - for example, anyone with the role ‘administrator’ is granted access.

Attribute Based Access Control (ABAC): The administrator defines which attributes a user must have to access an object - for example, only users with the job title ‘engineer’ and only those accessing the data from a certain location will be granted access. These policies are usually defined in XACML which stands for "eXtensible Access Control Markup Language’.

How Access Controls are Managed in the Cloud

The major public cloud providers include a number of access control features.
AWS for example, has long included clear instructions on managing access to consoles and S3 buckets. In RDS, users can tag and categorize resources and then build access policies based on those tags. 

Similar controls exist in Azure: Azure RBAC allows owners and administrators to create RBAC roles and currently Azure ABAC is in preview mode, and will allow for fine grained access control in Azure environment. 

Another aspect of access management in the cloud is ‘assumed roles’ in which a user is given access to a resource they aren’t usually permitted to access via a temporary key. This permission is meant to be temporary and permit cross account access as needed. Learn more about Azure security in our comprehensive guide.

The Problem: Access Controls Don't Follow the Data

So what’s missing? When data access controls are put in place in the cloud, they’re tied to the data store or database that the controls were created for. Imagine the following scenario. An administrator knows that a specific S3 bucket has sensitive data in it. Being a responsible cloud admin, they set up RBAC or ABAC policies and ensure only the right users have permissions at the right times. So far so good.

But now someone comes along and needs some of the data in that bucket. Maybe just a few details from a CSV file. They copy/paste the data somewhere else in your AWS environment.

Now what happens to that RBAC or ABAC policy? It doesn’t apply to the copied data - not only does the data not have the proper access controls set, but even if you’re able to find the exposed sensitive data, it’s not clear where it came from, or how it’s meant to be protected.

How Sentra’s DSPM Ensures that Data Always Has the Proper Access Controls

What we need is a way for the access control policy to travel with the data throughout the public cloud. This is one of the most difficult problems that Data Security Posture Management (DSPM) was created to tackle. 

DSPM is an approach to cloud security that focuses on finding and securing sensitive data, as opposed to the cloud infrastructure or applications. It accomplishes this by first discovering sensitive data (including shadow or abandoned data). DSPM classifies the data types using AI models and then determines whether the data has the proper security posture and how best to remediate if it doesn’t. 

While data discovery and classification are important, they’re not actionable without understanding:

  • Where the data came from
  • Who originally had access to the data
  • Who has access to the data now

The divide between what a user currently has access to vs what they should have access to, is referred to as the ‘authorization gap’. 

Sentra’s DSPM solution is able to understand who has access to the data and close this gap through the following processes:

  • Detecting unused privileges and adjusting for least privileged access based on user behavior: For example ,if a user has access to 10 data stores but only accesses 2 of them, Sentra will notice and suggest removing access from the other 8. 
  • Detecting user groups with excessive access to data. For example, if a user in the finance team has access to the developer environment, Sentra will raise a flag to remove the over privileged user. 
  • Detecting overprivileged similar data: For example, if sensitive data in production is only accessible by 2 users, but 85% of the data exists somewhere where more people have access, Sentra will alert the data owners to remediate. 

Access control and authorization remains one of the most important ways of securing sensitive cloud data. A data centric security solution can help ensure that the right access controls always follow your cloud data.

Enhancing AI Governance: The Crucial Role of Data Security

Enhancing AI Governance: The Crucial Role of Data Security

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. 

For more insights on managing AI and data privacy compliance, see our tips for security leaders.

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.

Understanding the Value of DSPM in Today’s Cloud Ecosystem

Understanding the Value of DSPM in Today’s Cloud Ecosystem

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.

Spooky Stories of Data Breaches

Spooky Stories of Data Breaches

As Halloween approaches, it’s the perfect time to dive into some of the scariest data breaches of 2024. Just like monsters hiding in haunted houses, cyber threats quietly move through the digital world, waiting to target vulnerable organizations.

The financial impact of cyberattacks is immense. Cybersecurity Ventures estimates global cybercrime will reach $9.5 trillion in 2024 and $10.5 trillion by 2025. Ransomware, the top threat, is projected to cause damages from $42 billion in 2024 to $265 billion by 2031.

If those numbers didn’t scare you, the 2024 Verizon Data Breach Investigations Report highlights that out of 30,458 cyber incidents, 10,626 were confirmed data breaches, with one-third involving ransomware or extortion. Ransomware has been the top threat in 92% of industries and, along with phishing, malware, and DDoS attacks, has caused nearly two-thirds of data breaches in the past three years.

Let's explore some of the most spine-tingling breaches of 2024 and uncover how they could have been avoided.

Major Data Breaches That Shook the Digital World

The Dark Secrets of National Public Data

The latest National Public Data breach is staggering, just this summer, a hacking group claims to have stolen 2.7 billion personal records, potentially affecting nearly everyone in the United States, Canada, and the United Kingdom. This includes American Social Security numbers. They published portions of the stolen data on the dark web, and while experts are still analyzing how accurate and complete the information is (there are only about half a billion people between the US, Canada, and UK), it's likely that most, if not all, social security numbers have been compromised.

The Haunting of AT&T

AT&T faced a nightmare when hackers breached their systems, exposing the personal data of 7.6 million current and 65.4 million former customers. The stolen data, including sensitive information like Social Security numbers and account details, surfaced on the dark web in March 2024.

Change Healthcare Faces a Chilling Breach

In February 2024, Change Healthcare fell victim to a massive ransomware attack that exposed the personal information of millions of individuals, with 145 million records exposed. This breach, one of the largest in healthcare history, compromised names, addresses, Social Security numbers, medical records, and other sensitive data. The incident had far-reaching effects on patients, healthcare providers, and insurance companies, prompting many in the healthcare industry to reevaluate their security strategies.

The Nightmare of Ticketmaster

Ticketmaster faced a horror of epic proportions when hackers breached their systems, compromising 560 million customer records. This data breach included sensitive details such as payment information, order history, and personal identifiers. The leaked data, offered for sale online, put millions at risk and led to potential federal legal action against their parent company, Live Nation.

How Can Organizations Prevent Data Breaches: Proactive Steps

To mitigate the risk of data breaches, organizations should take proactive steps. 

  • Regularly monitor accounts and credit reports for unusual activity.
  • Strengthen access controls by minimizing over-privileged users.
  • Review permissions and encrypt critical data to protect it both at rest and in transit. 
  • Invest in real-time threat detection tools and conduct regular security audits to help identify vulnerabilities and respond quickly to emerging threats.
  • Implement Data Security Posture Management (DSPM) to detect shadow data and ensure proper data hygiene (i.e. encryption, masking, activity logging, etc.) 

These measures, including multi-factor authentication and routine compliance audits, can significantly reduce the risk of breaches and better protect sensitive information.

Best Practices to Secure Your Data 

Enough of the scary news, how do we avoid these nightmares?

Organizations can defend themselves starting with Data Security Posture Management (DSPM) tools. By finding and eliminating shadow data, identifying over-privileged users, and monitoring data movement, companies can significantly reduce their risk of facing these digital threats.

Looking at these major breaches, it's clear the stakes have never been higher. Each incident highlights the vulnerabilities we face and the urgent need for strong protection strategies. Learning from these missteps underscores the importance of prioritizing data security.

As technology continues to evolve and regulations grow stricter, it’s vital for businesses to adopt a proactive approach to safeguarding their data. Implementing proper data security measures can play a critical role in protecting sensitive information and minimizing the risk of future breaches.
