Application control can help mitigate these types of security threats by restricting the applications that users are allowed to run and the code that runs in the System Core (kernel). Application control policies can also block unsigned scripts and MSIs, and restrict Windows PowerShell to run in Constrained Language Mode.
Although application control can significantly harden your computers against malicious code, we recommend that you continue to maintain an enterprise antivirus solution for a well-rounded enterprise security portfolio.
Application Installation Control feature in Windows 10

Starting in Windows 11 version 22H2, Smart App Control provides application control for consumers. Smart App Control is based on WDAC, allowing enterprise customers to create a policy that offers the same security and compatibility with the ability to customize it to run line-of-business (LOB) apps. To make it easier to implement this policy, an example policy is provided. The example policy includes Enabled:Conditional Windows Lockdown Policy rule which isn't supported for WDAC enterprise policies. This rule must be removed before you use the example policy. To use this example policy as a starting point for creating your own policy, see Create a custom base policy using an example WDAC base policy.
Application Control lets you strongly control what can run on devices you manage. This feature can be useful for devices in high-security departments, where it's vital that unwanted software can't run.
Preventing installation of apps from outside the StoreIn Windows 10 Creators Update, if you navigate to Settings > Apps > Apps & features, you can see app installing options. Here, you can choose from the following three options:
The WebRTC media engine in the Workspace app (HdxRtcEngine.exe) uses the Secure Real-time Transport Protocol (SRTP) for multimedia streams that are offloaded to the client. SRTP provides confidentiality and authentication to RTP. For this feature, symmetric keys (negotiated with DTLS) are used to encrypt media and control messages using the AES encryption cipher.
Once parental controls are enabled, two features are turned on by default. Firstly, internet browsing on Microsoft Edge browser becomes strict, ensuring that no adult content will be displayed in any of the search results. Secondly, InPrivate browsing is blocked, disabling incognito browsing by the child.
Duo Free plan customers have limited access to Duo policies. Free plans may only control the New User Policy via a global or shared application policy. All other available application settings are configured at the individual application.
The Global Policy is built-in and cannot be deleted. It always applies to all applications, so you should edit this policy if there are settings you'd like to control for all users and all applications. A summary of the Global Policy settings is shown on the Policies page. Settings at the Duo defaults are greyed out.
If certain applications require policy and controls that differ from the Global Policy, you can create a Custom Policy and assign it to those applications. Custom policies for an application can also be limited to specific groups. Custom Policies only need to specify the settings they wish to enforce.
Duo's trusted endpoints feature determines whether an access device is managed by your organization or is an unmanaged "bring your own" or unknown device. When an application loads the Duo Prompt it checks for the presence of a Duo device certificate or verification information from your MDM software or Duo Mobile app on that endpoint. You can use this policy to gain information about the devices used to access your Duo-protected web applications, and optionally restrict access from unmanaged endpoints.
The Duo Device Health application gives organizations more control over which laptop and desktop devices can access corporate applications based on the security posture of the device. The first time users log in to an application protected by the web-based Duo Prompt with the Device Health Application policy enabled, they are prompted to download and install the Duo Device Health application. Once the Device Health application is installed, Duo blocks access if the device is unhealthy based on the Duo policy definition and informs the user of the reason the authentication was denied.
If you configure operating system version policy settings for Windows and macOS, consider deploying the Device Health app to clients or enabling Device Health installation during Duo enrollment to enhance OS version detection for those systems, even if you don't use the Device Health policy options to verify security posture during authentication. Reliable detection and policy enforcement against Windows 11 requires the Duo Device Health application.
Duo's remembered devices feature is similar to the "remember my computer" or "keep me logged in" options users familiar to users from primary authentication to websites and applications. With the remembered devices feature enabled, users of the Duo traditional prompt and Duo Authentication for Windows Logon see a "Remember me" option, and users of Duo Universal Prompt see a "Trust this browser". When users select this option during Duo authentication, they will not be challenged for Duo authentication when they log in again from that device for a set period of time.
The Android and iOS mobile platforms can also be restricted to a minimum allowed version or blocked entirely. Blocking any version of a mobile OS platform, e.g. iOS or Android, not only restricts use of the mobile device to access Duo-protected resources that feature the browser-based traditional Duo Prompt or Universal Prompt on those OS platforms or versions, but also prevents use of Duo Mobile to approve Duo Push requests or generate usable passcodes to complete two-factor authentication for any Duo-protected application on devices running the restricted OS.
If you choose to enable phone calls as an authentication method, consider applying some additional policy controls (such as restricting User Location to your expected countries) or reducing your max credits per action telephony setting to only the credit amount needed for phone calls to your users' expected locations to avoid telephony misuse, especially if you've enabled the self-service portal for any of your applications.

Parties that control collection of personal data. In certain situations, we may allow a third party to control the collection of your personal data. For example, third party applications or extensions that run on Windows or Edge browser may collect personal data based on their own practices.
Microsoft offers preview, insider, beta or other free-of-charge products and features ("previews") to enable you to evaluate them while providing Microsoft with data about your use of the product, including feedback and device and usage data. As a result, previews can automatically collect additional data, provide fewer controls, and otherwise employ different privacy and security measures than those typically present in our products. If you participate in previews, we may contact you about your feedback or your interest in continuing to use the product after general release.
Local Software and Diagnostic Data. Some Online Services may require, or may be enhanced by, the installation of local software (e.g., agents, device management applications). The local software may collect Diagnostic Data (as defined in the Products and Services DPA) about the use and performance of that software. That data may be transmitted to Microsoft and used for the purposes described in the Products and Services DPA.
When you add an account to Outlook, your mail, calendar items, files, contacts, settings and other data from that account will automatically sync to your device. If you are using the mobile Outlook application, that data will also sync to Microsoft servers to enable additional features such as faster search, personalized filtering of less important mail, and an ability to add email attachments from linked file storage providers without leaving the Outlook application. If you are using the desktop Outlook application, you can choose whether to allow the data to sync to our servers. At any time, you can remove an account or make changes to the data that is synced from your account.
Skype contacts. If you use Outlook.com to manage contacts, Skype will automatically add the people you know to your Skype contact list until you tell the application to stop. With your permission, Skype will sync your device contacts periodically and check for other Skype users that match contacts in your device or Outlook address books. You are always in control of your contacts and can stop syncing at any time. You can block users if you do not want to receive their communications. If you choose to stop syncing your device contacts, or you are inactive on your device, any contacts that have not been matched during the synchronization process will be deleted from Skype. If you wish to invite any of your device or Outlook contacts to join a conversation, you can invite users to a 1:1 directly, or Microsoft can send an invitation on your behalf via SMS or email for invitations to group conversations. You can block users if you do not want to receive their communications; additionally, you can report a concern to Microsoft. 2ff7e9595c
