Mastering Data Governance Best Practices for Secure, Compliant Data

Learn six data governance best practices to help keep your organization’s data properly classified, secure and compliant.

Data governance best practices play an important role in maintaining the quality, security and compliance of an organization’s data assets. As data becomes increasingly critical to business decision-making, establishing a solid data governance framework helps organizations better manage risk and unlock value. By following these best practices, organizations can improve data accuracy, reliability and accessibility for authorized stakeholders.

Snowflake Horizon Catalog is a unified governance solution that provides capabilities to help manage and govern data across your Snowflake environment, including multi-cloud deployments. With Horizon Catalog, organizations can help discover, understand and manage data assets to support data classification, security controls and compliance workflows.

In this article, we share data governance best practices and offer guidance on implementing them effectively across your organization, enabling your data to be treated as a trusted and valuable asset. We also cover how to leverage Snowflake Horizon Catalog to achieve your data governance goals.

Today, one of the most valuable assets an organization can possess is data — but it can be difficult to extract its full value without a solid data governance program in place. Data governance is the framework organizations use to manage, organize and control their data assets. The goal is to provide decision-makers and users across the company with access to data they can trust.

We outline Snowflake’s data governance best practices below, and explain how each plays an important role in helping create a data environment that is designed to be reliable, secure and aligned with compliance requirements. Whether you are just starting out on your data governance journey or strengthening an existing program, these six principles can help your organization build a strong foundation for managing data and realizing more value from it.

These best practices also support key data governance use cases, including compliance, risk management and secure analytics.

An important first step in any data governance program is defining clear data ownership and stewardship roles for each data asset. This clarity about roles helps ensure accountability. Otherwise, data quality issues may be ignored, access requests go unanswered and compliance obligations may be overlooked. Identify and designate specific individuals to be responsible for certain data sets, and grant them the authority to decide how that data will be used, shared and maintained.

Data ownership roles are usually held by senior business leaders who understand the value and risk associated with the data, while data stewards normally handle the daily oversight of those data sets. To understand how this model fits into the broader data governance structure, explore Snowflake’s data governance framework guide.

To begin assigning data ownership, start by taking a comprehensive inventory of your data assets. Then, assign an owner to each one. Document each person’s responsibilities, which data sets they are responsible for overseeing, and clearly outline the escalation paths for any disputes.

Accurate data is valuable data — but low-quality data can result in poor decision-making, flawed analyses and costly mistakes. Establish data quality standards from the start to help promote data accuracy, completeness and consistency. You can tailor these standards to each business domain so those teams define what “good” data looks like for them.

In addition, you must develop a process to identify and fix data problems early before they propagate in downstream systems — this can include automated validation rules, regular audits and structured workflows for remediation. For additional guidance on maintaining data accuracy and reliability across systems, learn more about data integrity.

Access to data should follow the principle of least privilege, which means users and systems have access only to the data they genuinely need. Role-based access controls (RBAC) help ensure that data can only be accessed and modified by authorized personnel, making access management scalable, consistent and auditable.

RBAC also helps contain the damage in the event of a security incident in which credentials are compromised — the attacker is limited to accessing only the data allowed for that role. Snowflake’s data security framework guide offers additional guidance on RBAC and other data security best practices.

Data comes with varying levels of risk. A data classification framework categorizes data based on qualities such as the data’s sensitivity, business value and regulatory requirements. The framework then applies handling rules to each category, allowing for the enforcement of consistent security and access policies at scale.

Classification enables data security teams to concentrate their efforts and apply the strictest security controls on the more sensitive data. For more guidance on how to incorporate data classification into your governance and security strategy, review Snowflake’s data classification guide.

In order for a data governance program to be successful, it is typically overseen and driven by a cross-functional group that is authorized to set priorities, resolve problems, measure progress and ensure it stays aligned with business goals. Your data governance council should include leaders from all business units, IT, legal and compliance.

Governance programs may be more effective when they have executive sponsorship and support from multiple departments. For ways to keep these different stakeholders engaged, learn more about data governance strategy.

To help ensure your data governance council is effective, be sure it includes executives (such as a Chief Data Officer), data owners from core business units, legal and compliance staff, and leaders from IT or data engineering. The council should meet regularly and follow clear, documented decision-making processes — including appropriate escalation paths to resolve issues.

In addition to implementing data governance practices, you must monitor and measure the effectiveness of those practices. This assessment allows you to see if these practices are delivering value, how to improve them, and any areas where significant risk may still exist. Regular reporting is also beneficial in demonstrating compliance to auditors and regulators.
