Azure VPN gateway supports both Point-to-Site (P2S) and Site-to-Site (S2S) VPN connections. Using the Azure VPN gateway you can scale your employee's connections to securely access both your Azure deployed resources and your on-premises resources. For more information, see How to enable users to work remotely.

How to support remote workforce?

Another way to support a remote workforce is to deploy a Virtual Desktop Infrastructure (VDI) hosted in your Azure virtual network, secured with an Azure Firewall. For example, Azure Virtual Desktop (AVD) is a desktop and app virtualization service that runs in Azure. With Azure Virtual Desktop, you can set up a scalable and flexible environment in your Azure subscription without the need to run any additional gateway servers. You are only responsible for the AVD virtual machines in your virtual network. For more information, see Azure Firewall remote work support.

How many concurrent connections are there in SSTP?

If you are using Secure Sockets Tunneling Protocol (SSTP), the number of concurrent connections is limited to 128. To get a higher number of connections, we suggest transitioning to OpenVPN or IKEv2. For more information, see Transition to OpenVPN protocol or IKEv2 from SSTP.

Instead of giving everybody unrestricted permissions in your Azure subscription or resources, you can allow only certain actions at a particular scope. When planning your access control strategy, it's a best practice to grant users the least privilege to get their work done.

How to restrict access to Azure infrastructure?

You can restrict access to infrastructure and platform services management in Azure by using multi-factor authentication, X.509 management certificates, and firewall rules. The Azure portal and SMAPI require Transport Layer Security (TLS). However, services and applications that you deploy into Azure require you to take protection measures that are appropriate based on your application. These mechanisms can frequently be enabled more easily through a standardized hardened workstation configuration.

Why provision Azure management certificate on RD gateway?

Provision an Azure management certificate on the RD Gateway so that it is the only host allowed to access the Azure portal.

How does Azure work?

Azure subscribers may manage their cloud environments from multiple devices, including management workstations, developer PCs, and even privileged end-user devices that have task-specific permissions. In some cases, administrative functions are performed through web-based consoles such as the Azure portal. In other cases, there may be direct connections to Azure from on-premises systems over Virtual Private Networks (VPNs), Terminal Services, client application protocols, or (programmatically) the Azure Service Management API (SMAPI). Additionally, client endpoints can be either domain joined or isolated and unmanaged, such as tablets or smartphones.

What is Azure cloud service?

Azure cloud services configuration is performed through either the Azure portal or SMAPI, via the Windows PowerShell command-line interface or a custom-built application that takes advantage of these RESTful interfaces. Services using these mechanisms include Azure Active Directory (Azure AD), Azure Storage, Azure Websites, and Azure Virtual Network, and others.

What is RD gateway?

To centralize all administrative access and simplify monitoring and logging, you can deploy a dedicated Remote Desktop Gateway (RD Gateway) server in your on-premises network, connected to your Azure environment.

Can you use Azure logon restrictions?

You can use Azure logon restrictions to constrain source IP addresses for accessing administrative tools and audit access requests. To help Azure identify management clients (workstations and/or applications), you can configure both SMAPI (via customer-developed tools such as Windows PowerShell cmdlets) and the Azure portal to require client-side management certificates to be installed, in addition to TLS/SSL certificates. We also recommend that administrator access require multi-factor authentication.

Does Azure have authentication?

Some applications or services that you deploy into Azure may have their own authentication mechanisms for both end-user and administrator access, whereas others take full advantage of Azure AD. Depending on whether you are federating credentials via Active Directory Federation Services (AD FS), using directory synchronization or maintaining user accounts solely in the cloud, using Microsoft Identity Manager (part of Azure AD Premium) helps you manage identity lifecycles between the resources.

How to access Azure virtual machines?

What is Azure Private Link?

Use Azure Private Link to access Azure PaaS Services (for example, Azure Storage and SQL Database) over a private endpoint in your virtual network. Private Endpoints allow you to secure your critical Azure service resources to only your virtual networks. Traffic from your virtual network to the Azure service always remains on the Microsoft Azure backbone network. Exposing your virtual network to the public internet is no longer necessary to consume Azure PaaS Services.

What is Azure native control?

When to configure user defined routes?

We recommend that you configure user-defined routes when you deploy a security appliance for a virtual network. We talk about this in a later section titled secure your critical Azure service resources to only your virtual networks.

Can Azure access be on-premises?

Access from On-premises and peered networks: Access services running in Azure from on-premises over ExpressRoute private peering, VPN tunnels, and peered virtual networks using private endpoints. There's no need to configure ExpressRoute Microsoft peering or traverse the internet to reach the service. Private Link provides a secure way to migrate workloads to Azure.

What is the best practice for managing access control?

When planning your access control strategy, it's a best practice to manage to least privilege. Least privilege means you grant your administrators exactly the permission they need to do their job. There are three aspects to consider when you assign a role to your administrators: a specific set of permissions, over a specific scope, for a specific period of time. Avoid assigning broader roles at broader scopes even if it initially seems more convenient to do so. By limiting roles and scopes, you limit what resources are at risk if the security principal is ever compromised. Azure AD RBAC supports over 65 built-in roles. There are Azure AD roles to manage directory objects like users, groups, and applications, and also to manage Microsoft 365 services like Exchange, SharePoint, and Intune. To better understand Azure AD built-in roles, see Understand roles in Azure Active Directory. If there isn't a built-in role that meets your need, you can create your own custom roles.

How to enable MFA in Azure AD?

What are the three aspects to consider when assigning a role to your administrator?

There are three aspects to consider when you assign a role to your administrators: a specific set of permissions, over a specific scope, for a specific period of time. Avoid assigning broader roles at broader scopes even if it initially seems more convenient to do so.

Can you assign roles to Azure AD groups?

If you have an external governance system that takes advantage of groups, then you should consider assigning roles to Azure AD groups, instead of individual users. You can also manage role-assignable groups in PIM to ensure that there are no standing owners or members in these privileged groups. For more information, see Management capabilities for privileged access Azure AD groups.

What is Azure Virtual Desktop?

Azure Virtual Desktop is a service under Azure.

The client-side software is responsible for establishing a tunneling connection to the RAS and for the encryption of data.

What is the line of defense for remote access?

So, you have a three-layer line of defense working to protect remote access to your network: anti-virus, firewall, and VPN. The network security team should monitor alerts from these defenses constantly.

Why do devices have administrator rights?

To ensure that no unauthorized software is able to install itself, or by a user, and cause a virus, worm, Trojan or malware infection on a device, each device must deny administrator rights to the user of that particular device or all the employees in general. This ensures protection against Distributed Denial of Service (DDoS) attacks.

Where is the Secure Sockets Layer?
