How to manage Data Lake access and security?

At C&F, we face multiple tenants regularly using Data Lake features, such as access to data, APIs, additional services, etc. These use cases require flexibility in access validation applied at different levels. We take an approach that allows us to cover target system requirements and makes it possible to manage access to applications, APIs, and data (including different levels of granularity like databases, schemas, tables, or even particular rows). Next to data access, we keep track of advanced audit logs and monitor all policy changes. Thanks to that, our ops team can investigate every security change on our platform, which also brings valuable input for periodic access review activities.

Full picture of permissions in one place

All permissions management based on users, groups and roles is available in one system, instead of spreading it across different locations and making complicated to maintain.

Separation of duties

Define separate role-based access control to data based on user profile and their data usage requirements.

Management automation

Automated management based on source systems like AD/LDAP reduces risk of “human error” in users' membership management.

Improve rather than add a new tool

Flexibility allows to extend security platforms with customized plugins adjusted to target system requirements.

Access and security management in data lakes is fundamental to protecting sensitive information, ensuring compliance rules, and maintaining data integrity. It also plays an essential role in preventing breaches and enabling controlled and monitored access to critical data and audit logs of policy changes. Ensuring that only authorized users can access the data helps to maintain operational stability and prevents unexpected data disruptions and manipulations.

Overview

Data lakes are repositories that house various types of data that can be used by employees for analytics and insights. To protect this data from breaches and cybersecurity threats, it’s essential for organizations to implement strong data lake access controls and security. Our Data Lake Access Control solutions grant access for specific users based on their user profile and data usage requirements. In Azure Data Lake Storage, for example, we can assign roles such as Storage Blob Data Reader or Storage Blob Data Owner to better manage user permissions. This secures data and ensures it can only be accessed and used by those who need it. Our overall approach to data lake security ensures you have a full picture of permissions, automated management, and clearly defined access controls.
