Row-Level Security: Protecting Data at the User Level

Row-level security (RLS) acts as a protective gatekeeper for your data warehouse, ensuring users can only access the specific information they’re authorized to see. Think of it as an automatic filter that tailors data visibility based on who’s asking.

What Row-Level Security Is and Why It Matters

RLS is a mechanism that limits access to certain rows of data based on user roles, groups, or individual permissions. Unlike broader security measures that restrict access to entire tables or databases, RLS operates on a row-by-row basis, making it perfect for organizations with detailed data-sharing needs.

Imagine a company managing customer data across multiple regions. A sales representative working in the Midwest should only see customer records for their region, while the finance team might need to view revenue summaries without diving into detailed payment records. RLS enforces these rules automatically. When a user queries the database, their specific permissions determine what data they can see - no manual filtering required. This not only protects sensitive information but also helps organizations avoid compliance issues or accidental data leaks.

Querio builds on this concept by seamlessly integrating with your data warehouse’s existing RLS capabilities, ensuring secure and efficient data access.

How Querio Uses Row-Level Security

Querio doesn’t reinvent the wheel when it comes to security. Instead, it works directly with the RLS features built into major data warehouses like Snowflake, BigQuery, and PostgreSQL. By leveraging the security policies already in place, Querio ensures consistent enforcement of rules without adding extra layers of complexity.

Here’s how it works: Querio translates natural language queries into SQL while respecting the RLS policies defined in your data warehouse. It connects to your data warehouse using encrypted, read-only credentials, ensuring that security is enforced at the database level.

For example, if your Snowflake setup restricts sales data by territory, those same rules apply when using Querio. So, when a regional sales manager asks, “What were our Q3 sales numbers?” they’ll only see data for their assigned territory - even though the database contains global sales information. This consistency ensures that no matter how users access data - whether through Querio’s natural language interface or traditional SQL tools - the same security rules are always applied.

Querio’s approach guarantees both ease of use and uncompromised data security, offering a seamless experience for users and administrators alike.

Setup Tips for Administrators

To make the most of RLS, administrators need to properly configure policies within their data warehouse. Since Querio relies on the native RLS features of platforms like Snowflake, BigQuery, or PostgreSQL, the heavy lifting happens within these systems.

Here are some key steps for administrators:

• Identify and document access needs by department, team, or region. Use this understanding to create RLS policies tailored to these patterns.

• Write and implement RLS policies using Data Definition Language (DDL) statements provided by your data warehouse.

• Test your policies in a staging environment to ensure users can access the data they need - while being blocked from restricted information. Pay special attention to edge cases, like users with overlapping roles or access to multiple regions.

• Monitor performance regularly. Complex RLS rules can slow down queries on large datasets, so work with database administrators to fine-tune policies. Indexing strategies can often help balance security with query speed.

Data Masking and Access Controls: Hiding and Managing Sensitive Information

To strengthen the security of sensitive information, layers like data masking and access controls work alongside row-level security. These measures not only protect your data but also regulate how users interact with it. Together, they create a solid framework to safeguard your most critical information.

What Is Data Masking?

Data masking transforms sensitive information into anonymized versions that still retain their analytical usefulness. This allows users to work with realistic-looking data without exposing the actual values. For example, a customer record might display "John Smith" as "Jane Doe" or mask "123-45-6789" as "XXX-XX-6789." The format remains intact, but the true details stay hidden.

Querio takes advantage of the advanced data masking features available in modern data warehouses like Snowflake and BigQuery. By automatically applying the masking policies of these platforms, Querio ensures that sensitive information remains protected. For instance, a marketing analyst querying, "What’s the average age of customers in California?" will receive accurate insights without accessing personal details like names, addresses, or Social Security numbers. This approach balances data security with the ability to perform meaningful analyses, ensuring that trends, customer behaviors, and other metrics remain actionable without compromising privacy.

Access Controls: Managing Who Sees What

While data masking conceals sensitive information, access controls determine who can view and interact with the data in the first place. Querio enforces strict access control measures, including:

• Least privilege access: Users are granted only the permissions they need.

• Mandatory multi-factor authentication (MFA): Adds an extra layer of security.

• Regularly updated password policies: Ensures credentials remain secure.

Additionally, Querio uses role-based access control (RBAC) to provide fine-tuned permission management. Administrators can assign roles and permissions based on organizational structures, ensuring that users access only the data they’re authorized to see. Comprehensive audit trails log every interaction with the data, offering a full record of who accessed what and when. These logs are invaluable for compliance reporting and investigating potential security issues. Regular reviews of user permissions ensure that access remains appropriate as roles and responsibilities evolve.

Comparing Data Masking and Access Controls

When deciding between data masking and access controls, it’s helpful to understand their strengths and limitations:

Data masking is ideal for scenarios where teams need to analyze trends or patterns without exposing individual records. On the other hand, access controls are better suited for situations requiring precise control over who can access specific data. Combining these strategies ensures maximum security and utility - allowing sensitive data to remain protected while still meeting analytical and operational needs.

Natural Language Querying: Security Built into Every Question

One of Querio's standout features is its ability to take everyday business questions and turn them into secure, compliant database queries. This natural language interface doesn't just work within your data governance framework - it actively reinforces it. Every query automatically respects the rules you've established, ensuring security is baked into every step. Here's how Querio transforms plain language into secure insights.

How Querio Converts Plain English into Secure SQL

Imagine you ask Querio, "What's our revenue by region this quarter?" The platform kicks off a multi-step process designed with security at its core. First, Querio's AI interprets your question, identifying the data it needs to access. Then, it translates your inquiry into SQL queries that strictly enforce user permissions and governance policies, such as row-level security and data masking rules.

This process eliminates the risks that arise when users manually write SQL queries or when analytics tools bypass established security layers. For example, a sales manager using Querio will only see data for their assigned region - nothing more. If sensitive data, like Social Security numbers, is involved, the platform applies masking policies based on your data warehouse configuration. Every query, no matter who asks it or how it's phrased, follows the same secure process, ensuring consistent protection.

Once the query is complete, Querio instantly visualizes the results through clear charts and dashboards, giving users the insights they need - all without compromising data security.

Context Layers: Enhancing Accuracy and Protection

Querio goes beyond secure query conversion by introducing "context layers", which add another layer of accuracy and security. These layers integrate table joins, business metric definitions, and glossary terms into the query process, ensuring that every question aligns with your security protocols.

When administrators define these context layers, they aren't just improving the precision of queries - they're embedding security policies directly into Querio's understanding of your data. For instance, when defining a "customer" metric, admins can specify the relevant tables, fields, and security rules. This ensures that every query involving customers adheres to your organization's policies.

The glossary feature plays a key role in maintaining consistent security practices. Say a user asks about "sensitive customer information." Querio uses the glossary to interpret this term based on your organization's definitions, applying the correct masking or filtering rules. This prevents misinterpretations that could lead to unauthorized data access.

Context layers also act as guardrails, ensuring that users can't accidentally access restricted data. By understanding your data relationships and security boundaries, Querio avoids joining tables or exposing fields that a user isn't permitted to see. Even complex, multi-table queries stay within the appropriate access limits.

As business needs change, data teams can update these context layers, and the updates automatically apply to all future queries. This centralized approach ensures security policies remain consistent and up-to-date, without requiring users to navigate complex database structures or remember intricate access rules.

Best Practices for Maintaining Privacy and Security

Querio’s built-in security measures are enhanced by implementing thoughtful practices that balance speed with protection. Start by defining clear data governance policies before connecting your first database. Decide which users should access specific datasets and document these decisions within your organization to establish a strong foundation.

Regular access reviews are another key step. Conducting quarterly reviews helps ensure user permissions align with team changes, such as role shifts or new hires. Querio’s user management interface makes these updates simple and efficient.

Keep your context layer up to date. As your data structure evolves, make sure to revise table joins, metric definitions, and glossary terms to reflect current business needs. This ongoing maintenance minimizes security risks and ensures accurate query results.

Finally, train your team on secure querying practices. While Querio’s natural language interface includes built-in security controls, educating users empowers them to use the platform responsibly and identify potential issues early on.
