Critical Steps to Encryption & Key Management in the Azure Cloud [White Paper]

Posted by Michelle Larson on Aug 7, 2014 1:36:00 PM

Understanding Options and Responsibilities for Managing Encryption in the Microsoft Azure Cloud

Encryption & Key Management in Microsoft AzureIn this latest white paper, authored by Stephen Wynkoop (SQL Server MVP, Founder & Editor at SSWUG.ORG), Stephen will address how “data at rest is data at risk”, specifically looking at the Microsoft Azure Cloud as a selected platform.  The author covers a wide array of information, and discusses in detail how critical it is to do the important work of protecting information in a way that works both with your applications and with the compliance regulations & requirements that impact your company and industry.

Each of the key topic areas below are addressed in detail in the white paper:

Architecture Decisions Drive Technology Approach

The options range from fully-managed data storage and access (Windows Azure SQL Database, WASD) to setting up a SQL Server with a Virtual Machine instance. Each certainly has its place, but there are big differences in options they support.

  • Virtual Machines
  • Key Decision Points, VMs
  • Windows Azure SQL Database  (WASD)
  • SQL Server and Data Encryption Choices

Impact of Encryption

Encryption, and the impact of encryption on your systems, is a big area of concern for those deploying it. Three different areas are important to consider when impact on systems is considered.

  • Performance
  • Backup and Restore Operations
  • High Availability

Key Management Fundamentals

There are core best practices to consider while you’re deploying your selected solution. Some are procedural while others are software/hardware implementations. Keep in mind that the key is to protect your most important secret: the encryption keys. You must provide for protection of the encryption keys, while still providing for access, updates and rotation (key management) of those encryption keys throughout their lifecycle.

  • Segregation of Duties
  • Dual Control & Split Knowledge
  • Key Rotation
  • Protection of Keys
  • Access Controls and Audits, Logging

The author also covers how Townsend Security’s Alliance Key Manager provides answers to these challenges of working with the Microsoft Azure Cloud, securing information with encryption, and the critical need to manage the keys.
