Security defaultsĪzure security defaults are a set of security best practices enabled on new Azure tenants and easily enabled on existing tenants. It's so important that Microsoft now enables a set of security defaults, including MFA for all users, on new tenants. MFA adds additional authentication requirements, including something we have, such as a token or an authentication application, or something we are, such as a fingerprint reader.Įnabling MFA is one step that will significantly improve an organization's security posture by protecting against weak or stolen passwords. Traditional authentication uses a single factor, such as a known secret or password. One of the most recommended security configurations is multi-factor authentication (MFA). ASC is not limited to Azure on-premises servers or servers hosted in non-Azure clouds can be included as well. The score-based recommendations provide an easy way to quickly identify and reduce vulnerabilities based on Microsoft's best practices for cloud environments. If you are starting with Azure security or looking for ways to reduce vulnerabilities, ASC is a good place to start. It also lists a security score, insights, and recommended controls for the environment. At the top of the page is a list of the subscriptions, resources, and recommendations for those resources. The Security Center Overview page provides highlights of the status of the Azure resources in the environment. ASC can also extend to your on-premises environment. The ASC is a security management system designed to enhance the security posture of your cloud deployments. An excellent first step is with the Azure Security Center (ASC). Microsoft has many tools and services available to secure Azure it has so many, in fact, that it can be difficult to get started. Likewise, identifying the customer's part in securing PaaS services should be a step taken early in implementation. An assumption that Microsoft keeps OSs up to date with patching or safeguards the virtual network in an IaaS model is false and could expose an organization to security vulnerabilities. The delineation between Microsoft's responsibility and the customer's is important to understand, especially when securing the environment. No matter what type of service is moved to Azure, they all have the advantage of abstracting the physical infrastructure away from the service. The physical infrastructure, such as data centers, physical networking, and hosts, is the cloud provider's responsibility for all hosted services. Network security, patching, and application updates are the customer's responsibility with IaaS services. However, the responsibility falls to the customer with IaaS services, such as virtual networking and Azure Virtual Machines. Microsoft takes responsibility for maintaining networking, applications, and operating systems for SaaS services such as the Office 365 products. Identities and directory infrastructure, applications, network controls, and operating systems all have a different mix of responsibilities between the customer and Microsoft. The responsibility changes based on the service type.
