Applies to:Microsoft Defender for Endpoint

Microsoft recommends a layered approach to securing removable media, and Microsoft Defender for Endpoint provides multiple monitoring and control features to help prevent threats in unauthorized peripherals from compromising your devices:

1. Discover plug and play connected events for peripherals in Microsoft Defender for Endpoint advanced hunting. Identify or investigate suspicious usage activity.

2. Configure to allow or block only certain removable devices and prevent threats.

   1. Allow or block removable devices based on granular configuration to deny write access to removable disks and approve or deny devices by using USB device IDs. Flexible policy assignment of device installation settings based on an individual or group of Azure Active Directory (Azure AD) users and devices.

   2. Prevent threats from removable storage introduced by removable storage devices by enabling:
      - Microsoft Defender Antivirus real-time protection (RTP) to scan removable storage for malware.
      - The Attack Surface Reduction (ASR) USB rule to block untrusted and unsigned processes that run from USB.
      - Direct Memory Access (DMA) protection settings to mitigate DMA attacks, including Kernel DMA Protection for Thunderbolt and blocking DMA until a user signs in.

3. Create customized alerts and response actions to monitor usage of removable devices based on these plug and play events or any other Microsoft Defender for Endpoint events with custom detection rules.

4. Respond to threats from peripherals in real-time based on properties reported by each peripheral.

Note

These threat reduction measures help prevent malware from coming into your environment. To protect enterprise data from leaving your environment, you can also configure data loss prevention measures. For example, on Windows 10 devices you can configure BitLocker and Windows Information Protection, which will encrypt company data even if it is stored on a personal device, or use the Storage/RemovableDiskDenyWriteAccess CSP to deny write access to removable disks. Additionally, you can classify and protect files on Windows devices (including their mounted USB devices) by using Microsoft Defender for Endpoint and Azure Information Protection.

Discover plug and play connected events

You can view plug and play connected events in Microsoft Defender for Endpoint advanced hunting to identify suspicious usage activity or perform internal investigations.For examples of Defender for Endpoint advanced hunting queries, see the Microsoft Defender for Endpoint hunting queries GitHub repo.

Sample Power BI report templates are available for Microsoft Defender for Endpoint that you can use for Advanced hunting queries. With these sample templates, including one for device control, you can integrate the power of Advanced hunting into Power BI. See the GitHub repository for PowerBI templates for more information. See Create custom reports using Power BI to learn more about Power BI integration.

Allow or block removable devices

The following table describes the ways Microsoft Defender for Endpoint can allow or block removable devices based on granular configuration.

Restrict USB drives and other peripherals

To prevent malware infections or data loss, an organization may restrict USB drives and other peripherals. The following table describes the ways Microsoft Defender for Endpoint can help prevent installation and usage of USB drives and other peripherals.

All of the above controls can be set through the Intune Administrative Templates. The relevant policies are located here in the Intune Administrator Templates:

Note

Using Intune, you can apply device configuration policies to Azure AD user and/or device groups.The above policies can also be set through the Device Installation CSP settings and the Device Installation GPOs.

Note

Always test and refine these settings with a pilot group of users and devices first before applying them in production.For more information about controlling USB devices, see the Microsoft Defender for Endpoint blog.

Allow installation and usage of USB drives and other peripherals

One way to approach allowing installation and usage of USB drives and other peripherals is to start by allowing everything. Afterwards, you can start reducing the allowable USB drivers and other peripherals.

Note

Because an unauthorized USB peripheral can have firmware that spoofs its USB properties, we recommend only allowing specifically approved USB peripherals and limiting the users who can access them.

1. Enable Prevent installation of devices not described by other policy settings to all users.
2. Enable Allow installation of devices using drivers that match these device setup classes for all device setup classes.

To enforce the policy for already installed devices, apply the prevent policies that have this setting.

When configuring the allow device installation policy, you must allow all parent attributes as well. You can view the parents of a device by opening Device Manager and view by connection.

In this example, the following classes needed to be added: HID, Keyboard, and {36fc9e60-c465-11cf-8056-444553540000}. See Microsoft-provided USB drivers for more information.

If you want to restrict to certain devices, remove the device setup class of the peripheral that you want to limit. Then add the device ID that you want to add. Device ID is based on the vendor ID and product ID values for a device. For information on device ID formats, see Standard USB Identifiers.

To find the device IDs, see Look up device ID.

For example: Creality slicer vs cura.

1. Remove class USBDevice from the Allow installation of devices using drivers that match these device setup.
2. Add the device ID to allow in the Allow installation of device that match any of these device IDs.

Prevent installation and usage of USB drives and other peripherals

If you want to prevent the installation of a device class or certain devices, you can use the prevent device installation policies:

1. Enable Prevent installation of devices that match any of these device IDs and add these devices to the list.
2. Enable Prevent installation of devices using drivers that match these device setup classes.

Note

The prevent device installation policies take precedence over the allow device installation policies.

The Prevent installation of devices that match any of these device IDs policy allows you to specify a list of devices that Windows is prevented from installing.

To prevent installation of devices that match any of these device IDs:

1. Look up device ID for devices that you want Windows to prevent from installing.
2. Enable Prevent installation of devices that match any of these device IDs and add the vendor or product IDs to the list.

Look up device ID

You can use Device Manager to look up a device ID. Five nights at freddys rated m.

1. Open Device Manager.
2. Click View and select Devices by connection.
3. From the tree, right-click the device and select Properties.
4. In the dialog box for the selected device, click the Details tab.
5. Click the Property drop-down list and select Hardware Ids.
6. Right-click the top ID value and select Copy.

For information about Device ID formats, see Standard USB Identifiers.

For information on vendor IDs, see USB members.

The following is an example for looking up a device vendor ID or product ID (which is part of the device ID) using PowerShell:

The Prevent installation of devices using drivers that match these device setup classes policy allows you to specify device setup classes that Windows is prevented from installing.

To prevent installation of particular classes of devices:

1. Find the GUID of the device setup class from System-Defined Device Setup Classes Available to Vendors.
2. Enable Prevent installation of devices using drivers that match these device setup classes and add the class GUID to the list.

Block installation and usage of removable storage

1. Sign in to the Microsoft Azure portal.

2. Click Intune > Device configuration > Profiles > Create profile.

3. Use the following settings:

   • Name: Type a name for the profile
   • Description: Type a description
   • Platform: Windows 10 and later
   • Profile type: Device restrictions

4. Click Configure > General.

5. For Removable storage and USB connection (mobile only), choose Block. Removable storage includes USB drives, whereas USB connection (mobile only) excludes USB charging but includes other USB connections on mobile devices only.

6. Click OK to close General settings and Device restrictions.

7. Click Create to save the profile.

Allow installation and usage of specifically approved peripherals

Peripherals that are allowed to be installed can be specified by their hardware identity. For a list of common identifier structures, see Device Identifier Formats. Test the configuration prior to rolling it out to ensure it blocks and allows the devices expected. Ideally test various instances of the hardware. For example, test multiple USB keys rather than only one.

For a SyncML example that allows installation of specific device IDs, see DeviceInstallation/AllowInstallationOfMatchingDeviceIDs CSP. To allow specific device classes, see DeviceInstallation/AllowInstallationOfMatchingDeviceSetupClasses CSP.Allowing installation of specific devices requires also enabling DeviceInstallation/PreventInstallationOfDevicesNotDescribedByOtherPolicySettings.

Prevent installation of specifically prohibited peripherals

Microsoft Defender for Endpoint blocks installation and usage of prohibited peripherals by using either of these options:

• Administrative Templates can block any device with a matching hardware ID or setup class.
• Device Installation CSP settings with a custom profile in Intune. You can prevent installation of specific device IDs or prevent specific device classes.

Allow installation and usage of specifically approved peripherals with matching device instance IDs

Peripherals that are allowed to be installed can be specified by their device instance IDs. Test the configuration prior to rolling it out to ensure it allows the devices expected. Ideally test various instances of the hardware. For example, test multiple USB keys rather than only one.

You can allow installation and usage of approved peripherals with matching device instance IDs by configuring DeviceInstallation/AllowInstallationOfMatchingDeviceInstanceIDs policy setting.

Prevent installation and usage of specifically prohibited peripherals with matching device instance IDs

Peripherals that are prohibited to be installed can be specified by their device instance IDs. Test the configuration prior to rolling it out to ensure it allows the devices expected. Ideally test various instances of the hardware. For example, test multiple USB keys rather than only one.

You can prevent installation of the prohibited peripherals with matching device instance IDs by configuring DeviceInstallation/PreventInstallationOfMatchingDeviceInstanceIDs policy setting.

Limit services that use Bluetooth

Using Intune, you can limit the services that can use Bluetooth through the 'Bluetooth allowed services'. The default state of 'Bluetooth allowed services' settings means everything is allowed. As soon as a service is added, that becomes the allowed list. If the customer adds the Keyboards and Mice values, and doesn't add the file transfer GUIDs, file transfer should be blocked.

Use Microsoft Defender for Endpoint baseline settings

The Microsoft Defender for Endpoint baseline settings represent the recommended configuration for ATP. Configuration settings for baseline are located in the edit profile page of the configuration settings.

Prevent threats from removable storage

Removable storage devices can introduce additional security risk to your organization. Microsoft Defender for Endpoint can help identify and block malicious files on removable storage devices.

https://truewfil350.weebly.com/remove-adware-from-macbook-pro.html. Microsoft Defender for Endpoint can also prevent USB peripherals from being used on devices to help prevent external threats. It does this by using the properties reported by USB peripherals to determine whether or not they can be installed and used on the device.

Note that if you block USB devices or any other device classes using the device installation policies, connected devices, such as phones, can still charge.

Note

Always test and refine these settings with a pilot group of users and devices first before widely distributing to your organization.

The following table describes the ways Microsoft Defender for Endpoint can help prevent threats from removable storage.

For more information about controlling USB devices, see the Microsoft Defender for Endpoint blog.

Note

Because an unauthorized USB peripheral can have firmware that spoofs its USB properties, we recommend only allowing specifically approved USB peripherals and limiting the users who can access them.

Enable Microsoft Defender Antivirus Scanning

Protecting authorized removable storage with Microsoft Defender Antivirus requires enabling real-time protection or scheduling scans and configuring removable drives for scans.

• If real-time protection is enabled, files are scanned before they are accessed and executed. The scanning scope includes all files, including those on mounted removable devices such as USB drives. You can optionally run a PowerShell script to perform a custom scan of a USB drive after it is mounted, so that Microsoft Defender Antivirus starts scanning all files on a removable device once the removable device is attached. However, we recommend enabling real-time protection for improved scanning performance, especially for large storage devices.
• If scheduled scans are used, then you need to disable the DisableRemovableDriveScanning setting (enabled by default) to scan the removable device during a full scan. Removable devices are scanned during a quick or custom scan regardless of the DisableRemovableDriveScanning setting.

Note

We recommend enabling real-time monitoring for scanning. In Intune, you can enable real-time monitoring for Windows 10 in Device Restrictions > Configure > Microsoft Defender Antivirus > Real-time monitoring.

Block untrusted and unsigned processes on USB peripherals

End-users might plug in removable devices that are infected with malware.To prevent infections, a company can block USB files that are unsigned or untrusted.Alternatively, companies can leverage the audit feature of attack surface reduction rules to monitor the activity of untrusted and unsigned processes that execute on a USB peripheral.This can be done by setting Untrusted and unsigned processes that run from USB to either Block or Audit only, respectively.With this rule, admins can prevent or audit unsigned or untrusted executable files from running from USB removable drives, including SD cards.Affected file types include executable files (such as .exe, .dll, or .scr) and script files such as a PowerShell (.ps), VisualBasic (.vbs), or JavaScript (.js) files.

These settings require enabling real-time protection.

1. Sign in to the Microsoft Endpoint Manager.
2. Click Devices > Windows > Configuration Policies > Create profile.
3. Use the following settings:
   • Platform: Windows 10 and later
   • Profile type: Device restrictions
4. Click Create.
5. For Unsigned and untrusted processes that run from USB, choose Block.
6. Click OK to close settings and Device restrictions.

Protect against Direct Memory Access (DMA) attacks

DMA attacks can lead to disclosure of sensitive information residing on a PC, or even injection of malware that allows attackers to bypass the lock screen or control PCs remotely. The following settings help to prevent DMA attacks:

1. Beginning with Windows 10 version 1803, Microsoft introduced Kernel DMA Protection for Thunderbolt to provide native protection against DMA attacks via Thunderbolt ports. Kernel DMA Protection for Thunderbolt is enabled by system manufacturers and cannot be turned on or off by users.

   Beginning with Windows 10 version 1809, you can adjust the level of Kernel DMA Protection by configuring the DMA Guard CSP. This is an additional control for peripherals that don't support device memory isolation (also known as DMA-remapping). Memory isolation allows the OS to leverage the I/O Memory Management Unit (IOMMU) of a device to block unallowed I/O, or memory access, by the peripheral (memory sandboxing). In other words, the OS assigns a certain memory range to the peripheral. If the peripheral attempts to read/write to memory outside of the assigned range, the OS blocks it.

   Peripherals that support device memory isolation can always connect. Peripherals that don't can be blocked, allowed, or allowed only after the user signs in (default).

2. On Windows 10 systems that do not support Kernel DMA Protection, you can:

Create customized alerts and response actions

You can create custom alerts and response actions with the WDATP Connector and the custom detection rules:

https://hereqfile564.weebly.com/fender-squier-serial-number-indonesia.html. Wdatp Connector response Actions:

Investigate: Initiate investigations, collect investigation package, and isolate a machine.

Threat Scanning on USB devices.

Restrict execution of all applications on the machine except a predefined setMDATP connector is one of over 200 pre-defined connectors including Outlook, Teams, Slack, etc. Custom connectors can be built.

Custom Detection Rules Response Action:Both machine and file level actions can be applied.

For information on device control related advance hunting events and examples on how to create custom alerts, see Advanced hunting updates: USB events, machine-level actions, and schema changes.

Respond to threats

You can create custom alerts and automatic response actions with the Microsoft Defender for Endpoint Custom Detection Rules. Response actions within the custom detection cover both machine and file level actions. You can also create alerts and automatic response actions using PowerApps and Flow with the Microsoft Defender for Endpoint connector. The connector supports actions for investigation, threat scanning, and restricting running applications. It is one of over 200 pre-defined connectors including Outlook, Teams, Slack, and more. Custom connectors can also be built. See Connectors to learn more about connectors.

For example, using either approach, you can automatically have the Microsoft Defender Antivirus run when a USB device is mounted onto a machine.

There's a good chance Bluetooth technology is a regular part of your mobile experience these days. It covers everything from audio for wireless headphones and speakers, pairing gaming controllers and keyboards, tethering internet connections, and even occasionally transferring files over the air. It's a feature that gets more useful every year, which is pretty remarkable considering how relatively limited its scope was when it was created over 20 years ago.

The Bluetooth standard was originally conceived by Dr. Jaap Haartsen at Ericsson back in 1994. It was named for a renowned Viking and king who united Denmark and Norway in the 10th century. At the time, it was designed to replace RS-232 telecommunication cables, a much older standard conceived in 1960, by using short range UHF radio waves between 2.4 and 2.485 GHz. Although this occupies very similar frequencies to Wi-Fi, Bluetooth has always been designed as a much shorter range and lower power alternative.

Bluetooth was invented back in 1994, but the first Bluetooth phone didn't hit shelves until 2001.

Qualcomm vs Apple: the race to own Bluetooth audio

In 1988 the Bluetooth Special Interest Group (SIG) was formed, which to this day publishes and promotes the standard and its subsequent revisions. Bluetooth SIG initially only included Ericsson, IBM, Intel, Nokia, and Toshiba, but reached 4,000 members by the end of its first year. The group now contains over 30,000 member companies at various levels of influence.

The first consumer Bluetooth launched in 1999. It was a hands-free mobile headset which earned the technology the 'Best of Show Technology Award' at COMDEX. The Bluetooth 1.0 specification also officially launched that year, leading to the release of the first Bluetooth-equipped chipsets, dongles, mice, wireless PC cards, and mobile phone in 2000. The first Bluetooth mobile phone was the Sony Ericsson T36, but it was the revised T39 model which actually made it to store shelves in 2001. It offered customers a 101 x 54 Monochrome LCD display, tri-band GSM connectivity, WAP internet, and enough memory to store up to 1,000 contacts.

The early standard

Right out of the gate, Bluetooth 1.0 was equipped for a wide variety of uses. The RS-232 standard was widely used as a computer serial port, catering to internet modems, printers, mice, data storage, and a host of other peripherals. As its proposed replacement, Bluetooth was designed as a flexible packet-based protocol with a wide selection of profiles to suit these applications and more. RS-232 was also rather power-hungry for a physical connection, so Bluetooth was made to require much less power.

This first version wasn't without problems. Anonymity was an issue due to compulsory address broadcasting. There were connection problems aplenty. The 1.0 specification offered peak data speeds of just 721 kbps and connections couldn't reach much farther than 10 meters. Once you factored in real world performance, longer range connection quality, and the rather hefty header packets, the actual data rate available to applications was notably slower. The standard originally came with profiles for wireless voice and headsets, dial-up networking, fax, and file transfers, but this has expanded substantially since then.

Probably the most common use for Bluetooth in modern products is audio, yet the original standard was never designed for anything close to full bandwidth music. 721 Kbps is enough for a good compressed voice codec, even once you discount the header overheads and diminishing real world speeds at distance, but such limited bandwidth couldn't hope to cater to anything close Hi Res audio today or even CD quality at the time.

Bluetooth was originally conceived with wireless voice calls in mind, but not high quality stereo music streaming.

What's the situation with Bluetooth audio?

Bluetooth Storage Location

Apple butterfly 2 keyboard. The introduction of the A2DP profile mandated the use of the SBC audio codec as a minimum, rather than enforcing the direct transfer of other audio standards like mp3, mwa, and aac, even though these are supported. As a result, Bluetooth audio suffered from poor quality, and no core revisions to the specification have remedied this long-running problem.

Even the introduction of the Enhanced Data Rate for up to 3 Mbps didn't address the issue, as it's an optional component of the specification. Third party codecs like aptX and LDAC use higher bitrates and better compression methods, but Bluetooth remains a bottleneck for top quality wireless audio, despite its growing popularity.

Revisions compared

Bluetooth isn't just about audio though, and the specification has undergone numerous revisions since 1999 to improve the standard's data speeds and connection quality, feature set, and to help accommodate new use cases and markets. Most recently, Bluetooth SIG has been focusing on mesh networking, lower energy profiles, and longer range for IoT. In summary, the standard is faster and more secure, with more features than ever before.

Even so, Bluetooth's core capabilities have never been completely overhauled, to keep the platform as backwards compatible as possible. There have been lots of additions and improvements to the specification with each revision, ranging from new protocols and transmission modes, but the core data rate remains at 1 Mbps and the majority of legacy profiles remain active.

This first version wasn't without problems. Anonymity was an issue due to compulsory address broadcasting. There were connection problems aplenty. The 1.0 specification offered peak data speeds of just 721 kbps and connections couldn't reach much farther than 10 meters. Once you factored in real world performance, longer range connection quality, and the rather hefty header packets, the actual data rate available to applications was notably slower. The standard originally came with profiles for wireless voice and headsets, dial-up networking, fax, and file transfers, but this has expanded substantially since then.

Probably the most common use for Bluetooth in modern products is audio, yet the original standard was never designed for anything close to full bandwidth music. 721 Kbps is enough for a good compressed voice codec, even once you discount the header overheads and diminishing real world speeds at distance, but such limited bandwidth couldn't hope to cater to anything close Hi Res audio today or even CD quality at the time.

Bluetooth was originally conceived with wireless voice calls in mind, but not high quality stereo music streaming.

What's the situation with Bluetooth audio?

The introduction of the A2DP profile mandated the use of the SBC audio codec as a minimum, rather than enforcing the direct transfer of other audio standards like mp3, mwa, and aac, even though these are supported. As a result, Bluetooth audio suffered from poor quality, and no core revisions to the specification have remedied this long-running problem.

Even the introduction of the Enhanced Data Rate for up to 3 Mbps didn't address the issue, as it's an optional component of the specification. Third party codecs like aptX and LDAC use higher bitrates and better compression methods, but Bluetooth remains a bottleneck for top quality wireless audio, despite its growing popularity.

Revisions compared

Bluetooth isn't just about audio though, and the specification has undergone numerous revisions since 1999 to improve the standard's data speeds and connection quality, feature set, and to help accommodate new use cases and markets. Most recently, Bluetooth SIG has been focusing on mesh networking, lower energy profiles, and longer range for IoT. In summary, the standard is faster and more secure, with more features than ever before.

Even so, Bluetooth's core capabilities have never been completely overhauled, to keep the platform as backwards compatible as possible. There have been lots of additions and improvements to the specification with each revision, ranging from new protocols and transmission modes, but the core data rate remains at 1 Mbps and the majority of legacy profiles remain active.

The most notable (optional) additions to the specification include the Enhanced Data Rate for up to 3 Mbps in version 2.0, High Speed transfers over Wi-Fi using Bluetooth pairing in version 3.0, and the introduction of Low Energy in version 4.0. The table below shows when these major features were introduced, and how typical use cases for speed and range have evolved over time.

Honestly this way of looking at Bluetooth isn't really relevant to where the standard has been heading for the past few years. Rather than evolving in a single path, aiming for faster data speeds and longer range, the standard has increasingly split into Low Energy and Classic segments since version 4.0. Low Energy is tailored towards burst-like communication, like what's used by fitness trackers and internet-of-things products. Classic continues to provide a higher data rate for products requiring a constant connection.

The truth about Bluetooth 5 – Gary explains

Mirror for chromecast tv 2 6 1. The latest Bluetooth 5 revision continues down this path, splitting its improvements for Classic and Low Energy. This update places a heavy emphasis on boosting the range and data rate of its low energy and long range options, rather than revamping the classic protocol used by products like headphones.

There is also an equally wide selection of radio power options that offer ranges varying from very short to over 100 meters, and these aren't locked to any particular standard. The table below is a better representation of how Bluetooth standards are formulated today.

Wrap up

Over the past two decades, Bluetooth has evolved from a wireless replacement for old RS-232 cables to a fully fledged, far-reaching standard in its own right. It caters to everything from file sharing and device pairing, to wireless music and accessories. Today, the standard is perhaps facing its biggest fork yet, with a dual focus on retaining backwards compatibility while also powering increasingly low energy IoT devices and broad communication mesh networks. This definitely wasn't envisioned in the original specification.

Despite its limitation, the flexibility of this particular wireless standard has been its greatest asset. Estimates suggest as many as 10 billion Bluetooth devices will have shipped worldwide by the end of 2018, and Low Energy equipped devices look set for exponential growth, which means Bluetooth will stay a key driving factor not only in smartphones, but across countless technology market. Not bad for something from twenty years ago.
