Trusted Cloud: security, privacy, compliance, resiliency, and IP

Can you trust your cloud provider? That’s a question being asked a lot of these days, and with the newest version of our popular white paper Trusted Cloud: Microsoft Azure security, privacy, compliance, resiliency, and protected IP we’ve worked to provide you answers.

When we first published Trusted Cloud in 2015, the paper was 13 pages long and covered security, privacy, and compliance. Since then we’ve updated Trusted Cloud several times, and our newest edition stretches to 42 pages and includes new sections on resiliency and intellectual property. We understand 42 pages is a lot, so now we’re also offering Trusted Cloud both as a single paper and as five separate papers.

 

Security. The updated security section covers the multiple services that make up our defense-in-depth approach to security, including new services like our Security Information and Event Management (SIEM) offering, Azure Sentinel.

Compliance. Azure now offers an industry-leading 92 compliance offerings. We’ve seen tremendous growth in this area since the 21 offerings listed in the original 2015 paper. We’ve also added new services like Azure Blueprints, which provides you with templates to create, deploy, and update fully governed cloud environments to help meet compliance requirements.

Privacy. Since

CIS Azure Security Foundations Benchmark open for comment
CIS Azure Security Foundations Benchmark open for comment

One of the best ways to speed up securing your cloud deployments is to focus on the most impactful security best practices. Best practices for securing any service begins with a fundamental understanding of cybersecurity risk and how to manage it. As an Azure customer, you can leverage this understanding by using security recommendations from Microsoft to help guide your risk-based decisions as they’re applied to specific security configuration settings in your environment.

We partnered with the Center for Internet Security (CIS) to create the CIS Microsoft Azure Foundations Benchmark v1.  Since that submission, we’ve received good feedback and wanted to share it with the community for comment in a document we call the Azure Security Foundations Benchmark. This benchmark contains recommendations that help improve the security of your applications and data on Azure. The recommendations in this document will go into updating the CIS Microsoft Azure Foundations Benchmark v1, and are anchored on the security best practices defined by the CIS Controls, Version 7.

In addition, these recommendations are or will be integrated into Azure Security Center and their impact will be surfaced in the Azure Security Center Secure Score and the Azure Security Center Compliance Dashboard.

SAP on Azure–Designing for availability and recoverability

This is the third in a four-part blog series on Designing a great SAP on Azure Architecture.

Robust SAP on Azure Architectures are built on the pillars of security, performance and scalability, availability and recoverability, efficiency and operations.

We covered designing for performance and scalability previously and within this blog we will focus on availability and recoverability.

Designing for availability

Designing for availability ensures that your mission critical SAP applications such as SAP ERP or S/4HANA have high-availability (HA) provisions applied. These HA provisions ensure the application is resilient to both hardware and software failures and that the SAP application uptime is secured to meet your service-level-agreements (SLAs).

Within the links below, you will find a comprehensive overview on Azure virtual machine maintenance versus downtime where unplanned hardware maintenance events, unexpected downtime and planned maintenance events are covered in detail.

Customer Provided Keys with Azure Storage Service Encryption

Azure storage offers several options to encrypt data at rest. With client-side encryption you can encrypt data prior to uploading it to Azure Storage. You can also choose to have Azure storage manage encryption operations with storage service encryption using Microsoft managed keys or using customer managed keys in Azure Key Vault. Today, we present enhancement to storage service encryption to support granular encryption settings on storage account with keys hosted in any key store. Customer provided keys (CPK) enables you to store and manage keys in on-premises or key stores other than Azure Key Vault to meet corporate, contractual, and regulatory compliance requirements for data security.

Customer provided keys allows you to pass an encryption key as part of read or write operation to storage service using blob APIs. Since the encryption key is defined at the object level, you can have multiple encryption keys within a storage account. When you create a blob with customer provided key, storage service persists the SHA-256 hash of the encryption key with the blob to validate future requests. When you retrieve an object, you must provide the same encryption key as part of the request. For example, if a blob is created

Measuring your return on investment of Azure as a compliance platform

Today we’re pleased to introduce the release of Microsoft Azure is Helping Organizations Manage Regulatory Challenges More Effectively, a new International Data Corporation (IDC) white paper based on original research by IDC and sponsored by Microsoft. IDC studied Azure customers who are using Azure as a platform to meet regulatory compliance needs, with a special focus on government, healthcare, and financial customers. Azure Policy was cited by customers as having an important impact on meeting compliance obligations.

IDC found that these customers are realizing significant benefits by leveraging Azure capabilities to make their regulatory and compliance efforts more effective. Significant findings of research include:

•    Five-year return on investment (ROI) of 465 percent, worth an average of $4.29 Million.
•    Six-month payback on investment.
•    47 percent reduction in unplanned downtime.
•    35 percent reduction in compliance-related penalties.
•    A 24 percent increase in productivity for regulatory compliance teams.

Research summary findings

“Study participants reported use of Azure as a compliance platform helped them carry out their day–to-day compliance responsibilities more effectively. Azure helped them better manage spikes in the workload, enabled faster access to (and analysis of) data during audits, and reduced exposure to risk based on the

Azure Sentinel general availability: A modern SIEM reimagined in the cloud

Earlier this week, we announced that Azure Sentinel is now generally available. This marks an important milestone in our journey to redefine Security Information and Event Management (SIEM) for the cloud era. With Azure Sentinel, enterprises worldwide can now keep pace with the exponential growth in security data, improve security outcomes without adding analyst resources, and reduce hardware and operational costs.

With the help of customers and partners, including feedback from over 12,000 trials during the preview, we have designed Azure Sentinel to bring together the power of Azure and AI to enable Security Operations Centers to achieve more. There are lots of new capabilities coming online this week. I’ll walk you through several of them here.

Collect and analyze nearly limitless volume of security data

With Azure Sentinel, we are on a mission to improve security for the whole enterprise. Many Microsoft and non-Microsoft data sources are built right in and can be enabled in a single click. New connectors for Microsoft services like Cloud App Security and Information Protection join a growing list of third-party connectors to make it easier than ever to ingest and analyze data from across your digital estate.

Azure Security Center single click remediation and Azure Firewall JIT support

This blog post was co-authored by Rotem Lurie, Program Manager, Azure Security Center.​

Azure Security Center provides you with a bird’s eye security posture view across your Azure environment, enabling you to continuously monitor and improve your security posture using secure score in Azure. Security Center helps you identify and perform the hardening tasks recommended as security best practices and implement them across your machines, data services, and apps. This includes managing and enforcing your security policies and making sure your Azure Virtual Machines, non-Azure servers, and Azure PaaS services are compliant.

Today, we are announcing two new capabilities—the preview for remediating recommendations on a bulk of resources in a single click using secure score and the general availability (GA) of just-in-time (JIT) virtual machine (VM) access for Azure Firewall. Now you can secure your Azure Firewall protected environments with JIT, in addition to your network security group (NSG) protected environments.

Better security with enhanced access control experience in Azure Files

We are making it easier for customers to “lift and shift” applications to the cloud while maintaining the same security model used on-premises with the general availability of Azure Active Directory Domain Services (Azure AD DS) authentication for Azure Files. By integrating Azure AD DS, you can mount your Azure file share over SMB using Azure Active Directory (Azure AD) credentials from Azure AD DS domain joined Windows virtual machines (VMs) with NTFS access control lists (ACLs) enforced.

Azure AD DS authentication for Azure Files allows users to specify granular permissions on shares, files, and folders. It unblocks common use cases like single writer and multi-reader scenario for your line of business applications. As the file permission assignment and enforcement experience matches that of NTFS, lifting and shifting your application into Azure is as easy as moving it to a new SMB file server. This also makes Azure Files an ideal shared storage solution for cloud-based services. For example, Windows Virtual Desktop recommends using Azure Files to host different user profiles and leverage Azure AD DS authentication for access control.

Since Azure Files strictly enforces NTFS discretionary access control lists (DACLs), you can use familiar tools like Robocopy to

Disaster recovery of Azure disk encryption (V2) enabled virtual machines

Choosing Azure for your applications and services allows you take advantage of a wide array of security tools and capabilities. These tools and capabilities help make it possible to create secure solutions on Azure. Among these capabilities is Azure disk encryption, designed to help protect and safeguard your data to meet your organizational security and compliance commitments. It uses the industry standard BitLocker Drive Encryption for Windows and DM-Crypt for Linux to provide volume encryption for OS and data disks. The solution is integrated with Azure Key Vault to help you control and manage disk encryption keys and secrets, and ensures that all data on virtual machine (VM) disks are encrypted both in-transit and at rest while in Azure Storage.

Beyond securing your applications, it is important to have a disaster recovery plan in place to keep your mission critical applications up and running when planned and unplanned outages occur. Azure Site Recovery helps orchestrate replication, failover, and recovery of applications running on Azure Virtual Machines so that they are available from a secondary region if you have any outages in the primary region.

Azure Site Recovery now supports disaster recovery of Azure disk encryption (V2) enabled virtual machines without
