Description

Microsoft Azure offers a wide range of options to secure and protect your data, regardless of the format. Whether you're dealing with documents, SQL databases or big data, there are multiple solutions ranging from authentication to virtual networks.
 
In this course, we will cover the protection of your data from external and internal threats, whether those threats be malicious or accidental. We will see how good design combined with the right configuration can secure your organization's most precious asset: its data.

Transcript

Securing your organization's data lake is no trivial matter, but you have several lines of defense. There is authentication via Azure Active Directory OAuth bearer tokens. You can manage access with role-based access control, as we have seen earlier with storage accounts, and access control lists. Access control lists, or ACLs, as the name suggests, lists what read, write or execute access is permitted on a file or directory for a user. Data Lake Storage ACLs follow the open POSIX standard. POSIX stands for Portable Operating System Interface. This is an important consideration as Hadoop uses the same POSIX ACL structure.

Your stored data is encrypted, whether that is with a system-created key, or one that you have created or imported yourself, as we saw earlier in customer-managed keys. When the data is being transferred to lake storage it is also encrypted.

In addition to these measures, you can secure your data lake by integrating it with a virtual network. A virtual network provides another layer of access filtering, in as much as users have to be authenticated to access the network.
