To address this challenge, Microsoft Defender ATP uses Automated investigations to significantly reduce the volume of alerts that need to be investigated individually. The Automated investigation feature leverages various inspection algorithms, and processes used by analysts (such as playbooks) to examine alerts and take immediate remediation action to resolve breaches. This significantly reduces alert volume, allowing security operations experts to focus on more sophisticated threats and other high value initiatives.
|

### How threats are remediated
|
||||
|
||||
Depending on how you set up the machine groups and their level of automation, the Automated investigation will either require user approval (default) or automatically remediate threats.

|
||||
|
||||
## Investigate machines
|
||||
Investigate the details of an alert raised on a specific machine to identify other behaviors or events that might be related to the alert or the potential scope of breach.
|
||||
|
||||
You can click on affected machines whenever you see them in the portal to open a detailed report about that machine. Affected machines are identified in the following areas:
|
||||
|
||||
- The [Machines list](investigate-machines.md)
|
||||
- The [Alerts queue](alerts-queue.md)
|
||||
- The [Security operations dashboard](security-operations-dashboard.md)
|
||||
- [Machines list](investigate-machines.md)
|
||||
- [Alerts queue](alerts-queue.md)
|
||||
- [Security operations dashboard](security-operations-dashboard.md)
|
||||
- Any individual alert
|
||||
- Any individual file details view
|
||||
- Any IP address or domain details view
|
||||
|
||||
When you investigate a specific machine, you'll see:
|
||||
- Machine details, Logged on users, Machine risk, and Machine Reporting
|
||||
- Alerts related to this machine
|
||||
- Machine timeline
|
||||
|
||||
|
||||
- Machine details
|
||||
- Response actions
|
||||
- Cards (active alerts, logged on users, security assessment)
|
||||
- Tabs (alerts, timeline, security recommendations, software inventory, discovered vulnerabilities)
|
||||
|
||||
The machine details, logged on users, machine risk, and machine reporting sections display various attributes about the machine.
|
||||
|
||||
|
||||
**Machine details**</br>
|
||||
The machine details tile provides information such as the domain and OS of the machine. If there's an investigation package available on the machine, you'll see a link that allows you to download the package.
|
||||
## Machine details
|
||||
|
||||
For more information on how to take action on a machine, see [Take response action on a machine](respond-machine-alerts.md).
|
||||
The machine details section provides information such as the domain, OS, and health state of the machine. If there's an investigation package available on the machine, you'll see a link that allows you to download the package.
|
||||
|
||||
## Response actions
|
||||
|
||||
**Logged on users**</br>
|
||||
Clicking on the logged on users in the Logged on users tile opens the Users Details pane that displays the following information for logged on users in the past 30 days:
|
||||
Response actions run along the top of a specific machine page and include:
|
||||
|
||||
- Interactive and remote interactive logins
|
||||
- Network, batch, and system logins
|
||||
- Manage tags
|
||||
- Initiate Automated Investigation
|
||||
- Initiate Live Response Session
|
||||
|
||||
|
||||
Other actions are enabled if there is an investigation happening on that machine:
|
||||
|
||||
You'll also see details such as logon types for each user account, the user group, and when the account logon occurred.
|
||||
- Collect investigation package
|
||||
- Run antivirus scan
|
||||
- Restrict app execution
|
||||
- Isolate machine
|
||||
- Action center
|
||||
|
||||
You can take response actions in the action center, in a specific machine page, or in a specific file page.
|
||||
|
||||
For more information on how to take action on a machine, see [Take response action on a machine](respond-machine-alerts-windows-defender-advanced-threat-protection.md).
|
||||
|
||||
For more information, see [Investigate user entities](investigate-user.md).
|
||||
## Cards
|
||||
|
||||
**Machine risk**</br>
|
||||
The Machine risk tile shows the overall risk assessment of a machine. A machine's risk level can be determined using the number of active alerts or by a combination of multiple risks that may increase the risk assessment and their severity levels. You can influence a machine's risk level by resolving associated alerts manually or automatically and also by suppressing an alert. It's also indicators of the active threats that machines could be exposed to.
|
||||
### Active alerts
|
||||
|
||||
**Azure Advanced Threat Protection**</br>
|
||||
If you have enabled the Azure ATP feature and there are alerts related to the machine, you can click on the link that will take you to the Azure ATP page where more information about the alerts are provided.
|
||||
If you have enabled the Azure ATP feature and there are alerts related to the machine, you can view a high level overview of the alerts and risk level. More information is available in the "Alerts" drill down.
|
||||
|
||||
|
||||
|
||||
>[!NOTE]
|
||||
>You'll need to enable the integration on both Azure ATP and Microsoft Defender ATP to use this feature. In Microsoft Defender ATP, you can enable this feature in advanced features. For more information on how to enable advanced features, see [Turn on advanced features](advanced-features.md).
|
||||
|
||||
**Machine reporting**</br>
|
||||
Provides the last internal IP and external IP of the machine. It also shows when the machine was first and last seen reporting to the service.
|
||||
### Logged on users
|
||||
|
||||
## Alerts related to this machine
|
||||
The **Alerts related to this machine** section provides a list of alerts that are associated with the machine. You can also manage alerts from this section by clicking the circle icons to the left of the alert (or using Ctrl or Shift + click to select multiple alerts).
|
||||
The "Logged on users" tile shows the amount of users who have logged on in the past 30 days, along with the most and least frequent users. Selecting the "See all users" link opens the details pane that displays information such as user type, logon type, and first/last seen. For more information, see [Investigate user entities](investigate-user-windows-defender-advanced-threat-protection.md).
|
||||
|
||||
|
||||
|
||||
|
||||
This list is a filtered version of the [Alerts queue](alerts-queue.md), and shows the date when the alert's last activity was detected, a short description of the alert, the user account associated with the alert, the alert's severity, the alert's status in the queue, and who is addressing the alert.
|
||||
### Security assessments
|
||||
|
||||
You can also choose to highlight an alert from the **Alerts related to this machine** or from the **Machine timeline** section to see the correlation between the alert and its related events on the machine by right-clicking on the alert and selecting **Select and mark events**. This highlights the alert and its related events and helps distinguish them from other alerts and events appearing in the timeline. Highlighted events are displayed in all information levels whether you choose to view the timeline by **Detections**, **Behaviors**, or **Verbose**.
|
||||
The Security assessments tile shows the overall exposure level, security recommendations, installed software, and discovered vulnerabilities. A machine's exposure level is determined by the cumulative impact of it's pending security recommendations.
|
||||
|
||||
## Machine timeline
|
||||
The **Machine timeline** section provides a chronological view of the events and associated alerts that have been observed on the machine.
|
||||
|
||||
|
||||
This feature also enables you to selectively drill down into events that occurred within a given time period. You can view the temporal sequence of events that occurred on a machine over a selected time period.
|
||||
## Tabs
|
||||
|
||||
|
||||
The five tabs under the cards section show relevant security and threat prevention information related to the machine. In every tab, you can customize the columns that are shown.
|
||||
|
||||
Microsoft Defender ATP monitors and captures suspicious or anomalous behavior on Windows 10 machines and displays the process tree flow in the **Machine timeline**. This gives you better context of the behavior which can contribute to understanding the correlation between events, files, and IP addresses in relation to the machine.
|
||||
### Alerts
|
||||
|
||||
The **Alerts** section provides a list of alerts that are associated with the machine. This list is a filtered version of the [Alerts queue](alerts-queue-windows-defender-advanced-threat-protection.md), and shows a short description of the alert, severity (high, medium, low, informational), status in the queue (new, in progress, resolved), classification (not set, false alert, true alert), investigation state, category of alert, who is addressing the alert, and last activity. You can also filter the alerts and customize the columns.
|
||||
|
||||
### Search for specific events
|
||||
Use the search bar to look for specific timeline events. Harness the power of using the following defined search queries based on type:value pairs and event filter types to sift through the search results:
|
||||
|
||||
|
||||
- **Value** - Type in any search keyword to filter the timeline with the attribute you’re searching for. This search supports defined search queries based on type:value pairs.<br>
|
||||
You can use any of the following values:<br>
|
||||
- Hash: Sha1 or MD5
|
||||
- File name
|
||||
- File extension
|
||||
- Path
|
||||
- Command line
|
||||
- User
|
||||
- IP
|
||||
- URL
|
||||
When the circle icon to the left of an alert is selected, a fly-out appears. From this panel you can manage the alert and view more details such as incident number and related machines. Multiple alerts can be selected at a time.
|
||||
|
||||
- **Informational level** – Click the drop-down button to filter by the following levels:
|
||||
- Detections mode: displays Windows ATP Alerts and detections
|
||||
- Behaviors mode: displays "detections" and selected events of interest
|
||||
- Verbose mode: displays all raw events without aggregation or filtering
|
||||
To see a full page view of an alert including incident graph and process tree, select the title of the alert.
|
||||
|
||||
- **Event type** - Click the drop-down button to filter by events such as Windows - Microsoft Defender ATP alerts, Windows Defender Application Guard events, registry events, file events, and others.
|
||||
|
||||
Filtering by event type allows you to define precise queries so that you see events with a specific focus. For example, you can search for a file name, then filter the results to only see Process events matching the search criteria or to only view file events, or even better: to view only network events over a period of time to make sure no suspicious outbound communications go unnoticed.
|
||||
### Timeline
|
||||
|
||||
The **Timeline** section provides a chronological view of the events and associated alerts that have been observed on the machine. This can help you correlate any events, files, and IP addresses in relation to the machine.
|
||||
|
||||
Timeline also enables you to selectively drill down into events that occurred within a given time period. You can view the temporal sequence of events that occurred on a machine over a selected time period. To further control your view, you can filter by event groups or customize the columns.
|
||||
|
||||
>[!NOTE]

||||
|
||||
|
||||
|
||||
Some of the functionality includes:
|
||||
|
||||
- Search for specific events
|
||||
- Use the search bar to look for specific timeline events.
|
||||
- Filter events from a specific date
|
||||
- Select the calendar icon in the upper left of the table to display events in the past day, week, 30 days, or custom range. By default, the machine timeline is set to display the events from the past 30 days.
|
||||
- Use the timeline to jump to a specific moment in time by highlighting the section. The arrows on the timeline pinpoint automated investigations
|
||||
- Export detailed machine timeline events
|
||||
- Export the machine timeline for the current date or a specified date range up to seven days.
|
||||
|
||||
- **User account** – Click the drop-down button to filter the machine timeline by the following user associated events:
|
||||
- Logon users
|
||||
- System
|
||||
- Network
|
||||
- Local service
|
||||
Along with event time and users, one of the main categories on the timeline is "Details". They describe what happened in the events. The list of possible details are:
|
||||
|
||||
The following example illustrates the use of type:value pair. The events were filtered by searching for the user jonathan.wolcott and network events as the event type:
|
||||
- Contained by Application Guard
|
||||
- Active threat detected - when the detection happened, the threat was executing (i.e. it was running)
|
||||
- Remediation unsuccessful - remediation was invoked but failed
|
||||
- Remediation successful - the threat was stopped and cleaned up
|
||||
- Warning bypassed by user - SmartScreen warning appeared but the user dismissed it
|
||||
- Suspicious script detected
|
||||
- Alert category (e.g. lateral movement)- if the event is correlated to an alert, the tag will show the alert category
|
||||
|
||||
|
||||
You can also use the [Artifact timeline](investigate-alerts-windows-defender-advanced-threat-protection.md#artifact-timeline) feature to see the correlation between alerts and events on a specific machine.
|
||||
|
||||
The results in the timeline only show network communication events run in the defined user context.
|
||||
### Security recommendations
|
||||
|
||||
### Filter events from a specific date
|
||||
Use the time-based slider to filter events from a specific date. By default, the machine timeline is set to display the events of the current day.
|
||||
**Security recommendations** are generated from Microsoft Defender ATP's [Threat & Vulnerability Management](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-atp/tvm-dashboard-insights) capability. Selecting a recommendation will show a panel where you can view relevant details such as description of the recommendation and the potential risks associated with not enacting it.
|
||||
|
||||
Using the slider updates the listed alerts to the date that you select. Displayed events are filtered from that date and older.
|
||||
|
||||
|
||||
The slider is helpful when you're investigating a particular alert on a machine. You can navigate from the **Alerts view** and click on the machine associated with the alert to jump to the specific date when the alert was observed, enabling you to investigate the events that took place around the alert.
|
||||
### Software inventory
|
||||
|
||||
### Export machine timeline events
|
||||
You can also export detailed event data from the machine timeline to conduct offline analysis. You can choose to export the machine timeline for the current date or specify a date range. You can export up to seven days of data and specify the specific time between the two dates.
|
||||
The **Software inventory** section lets you view software on the device, along with any weaknesses or threats. Selecting the name of the software will take you to the software details page where you can view security recommendations, discovered vulnerabilities, installed machines, and version distribution.
|
||||
|
||||
|
||||
|
||||
### Navigate between pages
|
||||
Use the events per page drop-down to choose the number of alerts you’d like to see on the page. You can choose to display 20, 50, or 100 events per page. You can also move between pages by clicking **Older** or **Newer**.
|
||||
|
||||
From the **Machines list**, you can also navigate to the file, IP, or URL view and the timeline associated with an alert is retained, helping you view the investigation from different angles and retain the context of the event time line.
|
||||

||||
From the list of events that are displayed in the timeline, you can examine the behaviors or events in to help identify indicators of interests such as files and IP addresses to help determine the scope of a breach. You can then use the information to respond to events and keep your system secure.
|
||||
|

Expand an event to view associated processes related to the event. Click on the circle next to any process or IP address in the process tree to investigate additional details of the identified processes. This action brings up the **Details pane** which includes execution context of processes, network communications and a summary of meta data on the file or IP address.
|
||||
|
||||
The details pane enriches the ‘in-context’ information across investigation and exploration activities, reducing the need to switch between contexts. It lets you focus on the task of tracing associations between attributes without leaving the current context.
|
||||
|
||||
|
||||
### Discovered vulnerabilities
|
||||
|
||||
The **Discovered vulnerabilities** section shows the name, severity, and threat insights of discovered vulnerabilities on the device. Selecting specific vulnerabilities will show a description and details.

In an enterprise scenario, security operation teams are typically assigned a set of machines. These machines are grouped together based on a set of attributes such as their domains, computer names, or designated tags.
|
||||
|
||||
In Microsoft Defender ATP, you can create machine groups and use them to:
|
||||
- Limit access to related alerts and data to specific Azure AD user groups with [assigned RBAC roles](rbac.md)
|
||||
- Configure different auto-remediation settings for different sets of machines
|
||||
- Assign specific remediation levels to apply during automated investigations
|
||||
- In an investigation, filter the **Machines list** to just specific machine groups by using the **Group** filter.
|
||||
|
||||
You can create machine groups in the context of role-based access (RBAC) to control who can take specific action or see information by assigning the machine group(s) to a user group.

# Create and manage machine tags
|
||||
Add tags on machines to create a logical group affiliation. Machine group affiliation can represent geographic location, specific activity, importance level and others.
|
||||
|
||||
You can create machine groups in the context of role-based access (RBAC) to control who can take specific action or who can see information on a specific machine group or groups by assigning the machine group to a user group. For more information, see [Manage portal access using role-based access control](rbac.md).
|
||||
|
||||
You can also use machine groups to assign specific remediation levels to apply during automated investigations. For more information, see [Create and manage machine groups](machine-groups.md).
|
||||
|
||||
In an investigation, you can filter the Machines list to just specific machine groups by using the Groups filter.
|
||||
|
||||
|
||||
Machine tags support proper mapping of the network, enabling you to attach different tags to capture context and to enable dynamic list creation as part of an incident.

You can apply the following filters to limit the list of alerts and get a more focused view.
|
||||
|
||||
### Risk level
|
||||
Machine risk levels are indicators of the active threats that machines could be exposed to. A machine's risk level is determined using the number of active alerts and their severity levels. You can influence a machine's risk level by resolving associated alerts manually or automatically and also by suppressing an alert.
|
||||
|
||||
The risk level reflects the overall risk assessment of the machine based on a combination of factors, including the types and severity of active alerts on the machine. Resolving active alerts, approving remediation activities, and suppressing subsequent alerts can lower the risk level.
|
||||
|
||||
### Exposure level
|
||||
|
||||
The exposure level reflects the current exposure of the machine based on the cumulative impact of its pending security recommendations.
|
||||
|
||||
### OS Platform
|
||||

## Deep analysis
|
||||
|
||||
Cyber security investigations are typically triggered by an alert. Alerts are related to one or more observed files that are often new or unknown. Clicking a file takes you to the file view where you can see the file's metadata. To enrich the data related to the file, you can submit the file for deep analysis.
|
||||
|
||||
The deep analysis feature executes a file in a secure, fully instrumented cloud environment. Deep analysis results show the file's activities, observed behaviors, and associated artifacts, such as dropped files, registry modifications, and communication with IPs.

Quickly respond to detected attacks by isolating machines or collecting an investigation package. After taking action on machines, you can check activity details on the Action center.
|
||||
|
||||
Response actions run along the top of a specific machine page and include:
|
||||
|
||||
- Manage tags
|
||||
- Initiate Automated Investigation
|
||||
- Initiate Live Response Session
|

|
||||
- **Alerts queue** - Select the machine name beside the machine icon from the alerts queue.
|

|
||||
## Manage tags
|
||||
|
||||
Add or manage tags to create a logical group affiliation. Machine tags support proper mapping of the network, enabling you to attach different tags to capture context and to enable dynamic list creation as part of an incident.
|
||||
|
||||
For more information on machine tagging, see [Create and manage machine tags](machine-tags-windows-defender-advanced-threat-protection.md).
|
||||
|
||||
## Initiate Automated Investigation
|
||||
|
||||
You can start a new general purpose automated investigation on the machine if needed. While an investigation is running, any other alert generated from the machine will be added to an ongoing Automated investigation until that investigation is completed. In addition, if the same threat is seen on other machines, those machines are added to the investigation.
|
||||
|
||||
For more information on automated investigations, see [Overview of Automated investigations](automated-investigations-windows-defender-advanced-threat-protection.md).
|
||||
|
||||
## Initiate Live Response Session
|
||||
|
||||
Live response is a capability that gives you instantaneous access to a machine using a remote shell connection. This gives you the power to do in-depth investigative work and take immediate response actions to promptly contain identified threats – real-time.
|
||||
|
||||
Live response is designed to enhance investigations by enabling you to collect forensic data, run scripts, send suspicious entities for analysis, remediate threats, and proactively hunt for emerging threats.
|
||||
|
||||
For more information on live response, see [Investigate entities on machines using live response](live-response.md)
|
||||
|
||||
## Collect investigation package from machines
|
||||
|
||||
As part of the investigation or response process, you can collect an investigation package from a machine. By collecting the investigation package, you can identify the current state of the machine and further understand the tools and techniques used by the attacker.

To restrict an application from running, a code integrity policy is applied that only allows files to run if they are signed by a Microsoft issued certificate. This method of restriction can help prevent an attacker from controlling compromised machines and performing further malicious activities.
|
||||
|
||||
>[!NOTE]
|
||||
>You’ll be able to reverse the restriction of applications from running at any time.
|
||||
>You’ll be able to reverse the restriction of applications from running at any time. The button on the machine page will change to say **Remove app restrictions**, and then you take the same steps as restricting app execution.
|
||||
|
||||
1. Select the machine where you'd like to restrict an application from running from. You can select or search for a machine from any of the following views:
|
||||
|
||||
- **Security operations dashboard** - Select the machine name from the Top machines with active alerts section.
|
||||
- **Alerts queue** - Select the machine name beside the machine icon from the alerts queue.
|
||||
- **Machines list** - Select the machine name from the list of machines.
|
||||
- **Search box** - Select Machine from the drop-down menu and enter the machine name.
|
||||
|
||||
2. Open the **Actions** menu and select **Restrict app execution**.
|
||||
|
||||
|
||||
|
||||
3. Type a comment and select **Yes, restict app execution** to take action on the file.
|
||||
|
||||
|
||||
|
||||
The Action center shows the submission information:
|
||||
|
||||
|
||||
|
||||
- **Submission time** - Shows when the action was submitted.
|
||||
- **Status** - Indicates any pending actions or the results of completed actions.
|
||||
|
||||
When the application execution restriction configuration is applied, a new event is reflected in the machine timeline.
|
||||
Once you have selected **Restrict app execution** on the machine page, type a comment and select **Confirm**. The Action center will show the scan information and the machine timeline will include a new event.
|
||||
|
||||
|
||||
|
||||
**Notification on machine user**:</br>
|
||||
When an app is restricted, the following notification is displayed to inform the user that an app is being restricted from running:
|
||||
|
||||
|
||||
|
||||
## Remove app restriction
|
||||
Depending on the severity of the attack and the state of the machine, you can choose to reverse the restriction of applications policy after you have verified that the compromised machine has been remediated.
|
||||
|
||||
1. Select the machine where you restricted an application from running from.
|
||||
|
||||
2. Open the **Actions** menu and select **Remove app restrictions**.
|
||||
|
||||
|
||||
|
||||
3. Type a comment and select **Yes, remove restriction** to take action on the application. The machine application restriction will no longer apply on the machine.
|
||||
|
||||
|
||||
|
||||
## Isolate machines from the network
|
||||
|
||||
Depending on the severity of the attack and the sensitivity of the machine, you might want to isolate the machine from the network. This action can help prevent the attacker from controlling the compromised machine and performing further activities such as data exfiltration and lateral movement.
|
||||
|
||||
>[!IMPORTANT]
|
||||
>- Full isolation is available for machines on Windows 10, version 1703.
|
||||
>- Selective isolation is available for machines on Windows 10, version 1709 or later.
|
||||
|
||||
|
||||
This machine isolation feature disconnects the compromised machine from the network while retaining connectivity to the Microsoft Defender ATP service, which continues to monitor the machine.
|
||||
|
||||
On Windows 10, version 1709 or later, you'll have additional control over the network isolation level. You can also choose to enable Outlook and Skype for Business connectivity (a.k.a 'Selective Isolation').
|
||||
|
||||
>[!NOTE]
|
||||
>You’ll be able to reconnect the machine back to the network at any time.
|
||||
>You’ll be able to reconnect the machine back to the network at any time. The button on the machine page will change to say **Release from isolation**, and then you take the same steps as isolating the machine.
|
||||
|
||||
1. Select the machine that you want to isolate. You can select or search for a machine from any of the following views:
|
||||
Once you have selected **Isolate machine** on the machine page, type a comment and select **Confirm**. The Action center will show the scan information and the machine timeline will include a new event.
|
||||
|
||||

|
||||
|
||||
|
||||
|
||||
3. Select the check-box if you'd like to enable Outlook and Skype communication while the machine is isolated (a.k.a. 'Selective Isolation').
|
||||
|
||||
|
||||
|
||||
4. Type a comment and select **Yes, isolate machine** to take action on the machine.
|
||||
|
||||
>[!NOTE]
|
||||
>The machine will remain connected to the Microsoft Defender ATP service even if it is isolated from the network. If you've chosen to enable Outlook and Skype for Business communication, then you'll be able to communicate to the user while the machine is isolated.
|
||||
|
||||
The Action center shows the submission information:
|
||||
|
||||
|
||||
