Alert analysis – Remediation actions

On Endpoint

During Alerts analysis, if you find any endpoint is running malware, you can perform the following remediation actions on that endpoint.

The endpoint isolation and restore feature allows IR to isolate the endpoint from the network when an endpoint is running malware, to ensure the malware doesn’t spread to other endpoints.

When the endpoint is isolated, IR runs an investigation and resolves security issues. Once the endpoint is clean, IR can reconnect the endpoint to the internet.

Isolate: This action will isolate the endpoint from the network. This action will ensure that the malware is not spread in the network. This option is available only if the endpoint is infected. After isolation, IR runs an investigation and resolves security issues.
Reconnect: This action will reconnect the endpoint to the network. Once the endpoint is clean, IR can reconnect the endpoint to the network with this action. This option is available only if the endpoint is isolated.

On File

During Alerts analysis, if you find any suspicious file activity, you can perform the following remediation actions on that file.

Kill: This action will kill the process/file activity. Note that the file still will be available on the host computer and can be spawned/activated later. This option is available only if the file has spawned an active process. You can check the start time of that process under Process Details tab. This option is not available for a process that has ended.
Quarantine: You can quarantine a file on the host PC. This action will ensure that the process will not be launched by the file next time. You can restore a quarantined file anytime using the Restore button. The Quarantine action might fail if the sensor access to the file or folder is denied on the host PC. You cannot quarantine valid system files or installed program files as these files are Whitelisted by default when installed.

On Registry entries

From the alert, you can navigate to the process file that has spawned the regedit.exe file which is used to create/edit entries in the system registry. Clicking on the Values Created will display the registry entries in the right pane.

For any registry keys that are created as a result of any suspicious activity, you can select the registry keys and click Delete.

Note: You may not be able to delete a registry entry that has been renamed, or deleted already.

Additionally, you can do the following:

We can zoom in and out using mouse. We can adjust time window, if there are multiple events at same time, then there will be concentric circles on this view, else it will be a solid circle for a single event.
Also, when user clicks on this solid circle on this view, then user can see respective event on tree as well as details on right side panel.
When user clicks on concentric circles, then on right side panel all the concurrent events occurred at that same time are displayed. User can see further details of event by clicking on the events.
View the time sequence of activities performed by a process or its parent or siblings during the course of an alert generation.
