Data Security

It’s an age-old question at this point: should we operate in the cloud or on premises? But for many of today’s businesses, it’s not an either-or question, as the answer is both.

Although cloud has been the ‘latest and greatest’ for the past decade, very few organizations rely on it completely, and that’s probably not going to change anytime soon. According to a survey conducted by Foundry in 2023, 70% of organizations have brought some cloud apps or services back to on premises after migration due to security concerns, budget/cost control, and performance/reliability issues. 

But at the same time, the cloud is still growing in importance within organizations. Gartner projects that public cloud spending will increase by 20.4% in just the next year. With all of this in mind, it’s safe to say that most businesses are leveraging a hybrid approach and will continue to do so for a long time. 

But where does this leave today’s data security professionals, who must simultaneously secure cloud and on prem operations? The key to building a robust data security approach and future-proofing your hybrid organization is to adopt cloud-native data security that serves both areas equally well and, importantly, can match the expected cloud growth demands of the future.

On Prem Data Security Considerations

Because on premises data stores are here to stay for most organizations, teams must consider how they will respond to the unique challenges of on prem data security. Let’s dive into two areas that are unique to on premises data stores and require specific security considerations:

Network-Attached Storage (NAS) and File Servers

File shares, such as SMB (CIFS), NFS and FTP, play an integral role in making on prem data accessible. However, the specific structure and data formats used within file servers can pose challenges for data security professionals, including:

  • Identifying where sensitive data is stored and preventing its sprawl to unknown locations.
  • Nested or inherited permissions structures that could lead to overly permissive access.
  • Ensuring security and compliance across massive amounts of data that change continuously.

On Prem Databases With Structured and Unstructured Data

The variety in on prem databases also brings security challenges. Different databases such as MSSQL, Oracle, PostgreSQL, MongoDB, and MySQL and others use different data structures. Security professionals often struggle to compile structured, unstructured, and semi-structured data from these different sources to monitor their data security posture continuously. ETL operations do the heavy lifting, but this can lead to further obfuscation of the underlying (and often sensitive!) data. Plus, access control is managed separately within each of these databases, making it hard to institute least privilege.

Businesses need to use data security solutions that can scan all of these distinct store and data types, centralize security administration for these disparate storage areas, and respond to security issues commonly appearing in hybrid environments, such as misconfigurations, weak security, data proliferation and compliance violations. Legacy premise or cloud-only solutions won’t cut it in these situations, as they aren’t adapted to work with these specific considerations. 

Cloud Data Security Considerations

In addition to all these on prem data and storage variations, most organizations also leverage multiple cloud environments. This reality makes managing a holistic view of data security even more complex. A single organization might use several different cloud service providers (AWS, Azure, Google Cloud Platform, etc.), along with a variety of data lakes and data warehouses (e.g., Snowflake). Each of these platforms has a unique architecture and must be managed separately, making it challenging to centralize data security efforts.

Here are a few aspects of cloud environments that data security professionals must consider:

Massive Data Attack Surface

Because it’s so easy to move, change, or modify data in the cloud, data proliferates at an unprecedented speed. This leads to a huge attack surface of unregulated and unmonitored data. Security professionals face a new challenge in the cloud: securing data regardless of where it resides. But this can prove to be difficult when security teams might not even know that a copied or modified version of sensitive data exists in the first place. This organizational data that exists outside the centralized and secured data management framework, known as shadow data, poses a considerable threat to organizations, as they can’t protect what they don’t know.

Business Agility

In addition, security teams must figure out how to secure cloud data without slowing down other teams’ innovation and agility in the cloud. In many cases, teams must copy cloud data to complete their daily tasks. For example, a developer might need to stage a copy of production data for test purposes, or a business intelligence analyst might need to mine a copy of production data for new revenue opportunities. They must learn how to enforce critical policies without gatekeeping sensitive data that teams need to access for the business to succeed. 

Variety in Data Store Types

Cloud infrastructure often includes a variety of data store types as well. This includes cloud computing infrastructure such as IaaS, PaaS, DBaaS, application development components such as repositories and live applications, and, in many cases, several different public cloud providers. Each of these data stores exists in a silo, making it challenging for data security professionals to gain a centralized view of the entire organization’s data security posture. 

Unifying Cloud and On Prem Hybrid Environments With Cloud-Native Data Security

Because of its massive scale, dynamic nature, and service-oriented architecture, cloud infrastructure is more complex to secure than on prem. Generally speaking, anyone with a username and password for a cloud instance can access most of the data inside it by default. In other words, you can’t just secure its boundaries as you would with on premises data. And because new cloud instances are so easy to spin up, there are no assurances that a new cloud asset, that may contain data copies, will have the same protections as the original.  

Because of this complexity, legacy tools originally created for on prem environments, such as traditional data loss prevention (DLP), just won’t cut it in cloud environments. Yet cloud-only security offerings, such as those from the cloud service providers themselves, exclude the unique aspects of on premises environments or may be myopic in what they support. Instead, organizations must consider solutions that address both on prem and multi-cloud environments simultaneously. The answer lies in cloud-native data security that supports both

Because it’s built for the complexity of the cloud but includes support for on prem infrastructure, a cloud-native data security platform can follow your data across your entire hybrid environment and compile complex security posture information into a single location. Sentra approaches this concept in a unique way, enabling teams to see data similarity and movement between on prem and cloud stores. By understanding data movement, organizations can minimize the risks associated with data sprawl, while simultaneously securely enabling the business.

With a unified platform, teams can see a complete picture of their data security posture without needing to jump back and forth between the contexts and differing interfaces of on premises and cloud tools. A centralized platform also enables teams to consistently define and enforce policies for all types of data across all types of environments. In addition, it makes it easier to generate audit-ready reports and feed data into remediation tools from a single integration point.


Sentra’s Cloud-Native Approach to Hybrid Environments

Sentra offers a cloud-native data security posture management (DSPM) solution for monitoring various data types across all environments — from premises to SaaS to public cloud.

This is a major development, as our solution uniquely enables security teams to…

  • Automatically discover all data without agents or connectors, including data within multiple cloud environments, NFS / SMB File Servers, and both SQL/NoSQL on premises databases.
  • Compile information inside a single data catalog that lists sensitive data and its security and compliance posture.
  • Receive alerts for misconfigurations, weak encryptions, compliance violations, and much more.
  • Identify duplicated data between environments, including on prem, cloud, and SaaS, enabling organizations to clean up unused data, control sprawl and reduce risks.
  • Track access to sensitive data stores from a single interface and ensure least privilege access.

Plus, when you use Sentra, your data never leaves your environment - it remains in place, secure and without disruption. We leverage native cloud serverless processing functions (ex. AWS Lambda) to scan your cloud data. For on premises, we scan all data within your secure networks and only send metadata to the Sentra cloud platform for further reporting and analysis.

Sentra also won’t interrupt your production flow of data, as it works asynchronously in both cloud and on premises environments (it scans on prem by creating temporary copies to scan in the customer cloud environment).

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.
