Azure’s layered approach to physical security

We have heard from many customers that cloud security is one of their top concerns. Another thing we’ve heard from customers is that they want clarity around what they are responsible for securing in Azure and what Azure will do. Azure helps provide a highly secure foundation, built from the ground up, to host your infrastructure, applications, and data.

We understand the importance of protecting customer data, which is why we are committed to helping secure the datacenters that contain your data. Microsoft has invested over a billion dollars into security, including the physical security of the Azure platform, so you can devote your time and resources towards other business initiatives. Over the next few months, as part of the secure foundation blog series, we’ll discuss the components of physical, infrastructure (logical) and operational security that help make up Azure’s platform. Today, we are focusing on physical security.

Physical security refers to how Microsoft designs, builds and operates datacenters in a way that strictly controls physical access to the areas where customer data is stored. Our datacenters are certified to comply with the most comprehensive portfolio of internationally-recognized standards and certifications of any cloud service provider. We have an entire

Just-in-Time VM Access is generally available

Azure Security Center provides several threat prevention mechanisms to help you reduce surface areas susceptible to attack. One of those mechanisms is Just-in-Time (JIT) VM Access. Today we are excited to announce the general availability of Just-in-Time VM Access, which reduces your exposure to network volumetric attacks by enabling you to deny persistent access while providing controlled access to VMs when needed.

When you enable JIT for your VMs, you can create a policy that determines the ports to be protected, how long ports remain open, and approved IP addresses from where these ports can be accessed. The policy helps you stay in control of what users can do when they request access. Requests are logged in the Azure Activity Log, so you can easily monitor and audit access. The policy will also help you quickly identify existing virtual machines that have JIT enabled and virtual machines where JIT is recommended.

This feature is available in the standard pricing tier of Security Center, and you can try Security Center for free for the first 60 days.

Security Center Playbooks and Azure Functions Integration with Firewalls

Every second counts when an attack has been detected. We have heard from you that you need to be able to quickly take action against detected threats. At Ignite 2017, we announced Azure Security Center Playbooks, which allow you to control how you want to respond to threats detected by Security Center. You can manually run a Security Center Playbooks when a Security Center alert is triggered, reducing time to response, and helping you stay in control of your security posture. Today, we are going to look at the specific example of how Azure Functions work with Security Center Playbooks to help you rapidly respond to detected threats against your Palo Alto VM-Series firewall.

In this scenario, Azure Security Center has detected and notified you of an RDP Brute Force attack. To help you block the source IP address of that attack in your Palo Alto VM-Series firewall, there are a couple steps you need to complete. You will first need to create an Azure Function which can be completed in the Functions Apps in the Azure portal, for HTTP Trigger using C# programming language. The Azure Function is what allows Security Center Playbooks to communicate with the Palo Alto

Spring Security Azure AD: Wire up enterprise grade authentication and authorization

We are pleased to announce that Azure Active Directory (Azure AD) is integrated with Spring Security to secure your Java web applications. With only few lines of configurations, you can wire up enterprise grade authentication and authorization for your Spring Boot project.

With Spring Boot Starter for Azure AD, Java developers now can get started quickly to build the authentication workflow for a web application that uses Azure AD and OAuth 2.0 to secure its back end. It also enables developers to create a role based authorization workflow for a Web API secured by Azure AD with the power of the Spring Security.

Getting Started

Take the To-do App, which Erich Gamma showed on SpringOne 2017, as an example. The sample is composed of two layers: Angular JS client and Spring Boot RESTful web service. It illustrates the flow to login and retrieves user’s information using AAD Graph API.

Authorization Flow Chart

The authorization flow is composed of 3 phrases:

Login with credentials and get validated through Azure AD. Retrieve token and membership information from Azure AD Graph API. Evaluate the membership for role-based authorization.

Register a new application in Azure AD

Managing Azure Secrets on GitHub Repositories
Managing Azure Secrets on GitHub Repositories

Background

An increasing number of developers across the globe use GitHub to host their projects, and many of them use GitHub public repositories for their open source work. While this is a great way to contribute and leverage the power of the community, it does come with a unique set of responsibilities. Particularly around managing credentials and other secrets.

Examples of Azure secrets are authentication credentials that should not be made public. These include things such as passwords, private keys, database connection strings, and storage account keys that are managed by Azure tenants.

In Azure, we take security very seriously. Azure secrets are considered sensitive and should not be made publicly available. An exposed secret could lead to the compromise of your Azure subscription, your cloud assets, as well as on-premises assets and data; putting your applications or services at significant risk.

Microsoft Credential Scanner Preview

To help protect our customers, Azure runs Credential Scanner aka CredScan. CredScan monitors all incoming commits on GitHub and checks for specific Azure tenant secrets such as Azure subscription management certificates and Azure SQL connection strings. 

Internally at Microsoft we’ve been developing and leveraging CredScan to protect Azure and our 1st party services and
