File/Malware Events and Network File Trajectory

The following topics provide an overview of file and malware events, local malware analysis, dynamic analysis, captured files, and network file trajectories.

About File/Malware Events and Network File Trajectory

File policies automatically generate file and malware events for matched traffic, and log captured file information. When a file policy generates a file or malware event, or captures a file, the system also automatically logs the end of the associated connection to the Firepower Management Center database. You can analyze this data to address any negative impacts and block future attacks.

Based on the file analysis results, you can review captured files and generated malware and file events using tables on pages available under the Analysis > Files menu. When available, you can examine a file's composition, disposition, threat score, and dynamic analysis summary report for further insight into the malware analysis.

To further target your analysis, you can use a malware file’s network file trajectory (a map of how the file traversed your network, passing among hosts, as well as various file properties) to track the spread of an individual threat across hosts over time, allowing you to concentrate outbreak control and prevention efforts where most useful.

If you configure local malware analysis or dynamic analysis in a file rule, the system preclassifies files matching the rule and generates a file composition report.

If your organization has deployed AMP for Endpoints and integrated that deployment with your Firepower Management Center, you can also import records of scans, malware detections, and quarantines, as well as indications of compromise (IOC) identified by that product. This data is displayed alongside event data gathered by Firepower for a more complete picture of malware on your network.

The Context Explorer, dashboards, and reporting features can also aid a deeper understanding of the files and malware detected, captured, and blocked. You can also use events to trigger correlation policy violations, or alert you via email, SMTP, or syslog.


Note


To configure your system to detect malware and generate file and malware events, see File Policies and Malware Protection.


File and Malware Events

The Firepower Management Center can log various types of file and malware events. The information available for any individual event can vary depending on how and why it was generated:

  • File events represent files, including malware, detected by the Firepower system (AMP for Networks.) File events do not contain AMP for Endpoints-related fields.

  • Malware events represent malware detected by either AMP for Networks or AMP for Endpoints; malware events can also record data other than threats from your AMP for Endpoints deployment, such as scans and quarantines.

  • Retrospective malware events represent files detected by AMP for Networks whose dispositions (whether the files are malware) have changed.


Note


  • Files identified as malware by AMP for Networks generate both a file event and a malware event. Malware events generated by AMP for Endpoints do not have corresponding file events.

  • File events generated by inspecting NetBIOS-ssn (SMB) traffic do not immediately generate connection events because the client and server establish a persistent connection. The system generates connection events after the client or server ends the session.

  • The Firepower System supports the display and input of file names that use Unicode (UTF-8) characters. However, Unicode file names appear in PDF reports in transliterated form. Additionally, the SMB protocol replaces unprintable characters in file names with periods.


File and Malware Event Types

File Events

The system logs the file events generated when a managed device detects or blocks a file in network traffic, according to the rules in currently deployed file policies.

When the system generates a file event, the system also logs the end of the associated connection to the Firepower Management Center database, regardless of the logging configuration of the invoking access control rule.

Malware Events

The Firepower system (specifically the AMP for Networks feature) generates malware events when it detects malware in network traffic as part of your overall access control configuration. Malware events contain the disposition of the resulting event and contextual data about how, where, and when the malware was detected.

File Disposition and File Action in Malware Events

Each file rule has an associated action that determines how the system handles traffic that matches the conditions of the rule. If you select Block Malware or Malware Cloud Lookup as file rule action, the system queries the AMP cloud to determine if files traversing your network contain malware, then block files that represent threats. Cloud lookup allows you to obtain and log the file's disposition based on its SHA-256 hash value.

The following table describes the file action that associates with the file disposition returned by the AMP cloud:

Note

 

Under the file policy editor Advanced Settings, you can set a threshold threat score for If AMP Cloud disposition is Unknown, override disposition based upon threat score option. If you set a threshold threat score, files with an AMP cloud verdict of Unknown are considered malware if their dynamic analysis score is equal to or worse than the threshold.

Retrospective Malware Events

For malware detected in network traffic, dispositions can change. For example, the AMP cloud can determine that a file that was previously thought to be clean is now identified as malware, or the reverse—that a malware-identified file is actually clean. When the disposition changes for a file you queried in the last week, the AMP cloud notifies the system. Then, two things happen:

  • The Firepower Management Center generates a new retrospective malware event.

    This new retrospective malware event represents a disposition change for all files detected in the last week that have the same SHA-256 hash value. For that reason, these events contain limited information: the date and time the Firepower Management Center was notified of the disposition change, the new disposition, the SHA-256 hash value of the file, and the threat name. They do not contain IP addresses or other contextual information.

  • The Firepower Management Center changes the file disposition for previously detected files with the retrospective event’s associated SHA-256 hash value.

    If a file’s disposition changes to Malware, the Firepower Management Center logs a new malware event to its database. Except for the new disposition, the information in this new malware event is identical to that in the file event generated when the file was initially detected.

    If a file’s disposition changes to Clean, the Firepower Management Center does not delete the malware event. Instead, the event reflects the change in disposition. This means that files with clean dispositions can appear in the malware table, but only if they were originally thought to be malware. Files that were never identified as malware appear only in the files table.

Malware Events Generated by AMP for Endpoints

If your organization uses AMP for Endpoints, individual users install lightweight connectors on endpoints: computers and mobile devices. Connectors can inspect files upon upload, download, execution, open, copy, move, and so on. These connectors communicate with the AMP cloud to determine if inspected files contain malware.

When a file is positively identified as malware, the AMP cloud sends the threat identification to the Firepower Management Center. The AMP cloud can also send other kinds of information to the Firepower Management Center, including data on scans, quarantines, blocked executions, and cloud recalls. The Firepower Management Center logs this information as malware events.


Note


The IP addresses reported in malware events generated by AMP for Endpoints may not be in your network map—and may not even be in your monitored network at all. Depending on your deployment, level of compliance, and other factors, endpoints in your organization monitored by AMP for Endpoints may not be the same hosts as those monitored by AMP for Networks.


Malware Event Analysis with AMP for Endpoints

If your organization has deployed Cisco AMP for Endpoints:

  • You can configure the system to display malware events detected by AMP for Endpoints on Firepower Management Center event pages, alongside events detected by AMP for Networks.

  • If you are using the AMP public cloud, you can view file trajectory and other information about a particular SHA in AMP for Endpoints.

To configure the above functionality, see Integrate Firepower and AMP for Endpoints.

Event Data from AMP for Endpoints

If your organization has deployed AMP for Endpoints for malware protection, you can configure the system to let you work in FMC with file and malware data from AMP for Endpoints.

However, you should be aware of the differences between file and malware data from AMP for Endpoints and file and malware data from AMP for Networks (malware protection using the Firepower system.)

Because AMP for Endpoints malware detection is performed at the endpoint at download or execution time, while managed devices detect malware in network traffic, the information in the two types of malware events is different. For example, malware events detected by AMP for Endpoints ("endpoint-based malware") contain information on file path, invoking client application, and so on, while malware detections in network traffic contain port, application protocol, and originating IP address information about the connection used to transmit the file.

As another example, for malware events detected by AMP for Networks ("network-based malware events"), user information represents the user most recently logged into the host where the malware was destined, as determined by network discovery. But AMP for Endpoints-reported users represent the user currently logged into the endpoint where the malware was detected.


Note


Depending on your deployment, endpoints monitored by AMP for Endpoints may not be the same hosts as those monitored by AMP for Networks. For this reason, malware events generated by AMP for Endpoints do not add hosts to the network map. However, the system uses IP and MAC address data to tag monitored hosts with indications of compromise obtained from your AMP for Endpoints deployment. If two different hosts monitored by different AMP solutions have the same IP and MAC address, the system can incorrectly tag monitored hosts with AMP for Endpoints IOCs.


The following table summarizes the differences between the event data generated by Firepower when using a Malware license, and event data generated by AMP for Endpoints.

Using File and Malware Event Workflows

Use this procedure to view file and malware events in a table and to manipulate the event view depending on the information relevant to your analysis. The page you see when you access events differs depending on the workflow, which is simply a series of pages you can use to evaluate events by moving from a broad to a more focused view. You can also create a custom workflow that displays only the information that matches your specific needs.

In a multidomain deployment, you can view data for the current domain and for any descendant domains. You cannot view data from higher level or sibling domains.

You must be an Admin or Security Analyst user to perform this task.

Procedure


Choose one of the following:

  • Analysis > Files > File Events
  • Analysis > Files > Malware Events

Tip

 

In the table view of events, several fields are hidden by default. To show a hidden field in an event view, expand the search constraints, then click the field name under Disabled Columns.

Tip

 

To quickly view the connections where specific files were detected, choose the files using the check boxes in the table, then choose Connections Events from the Jump to drop-down list.

Tip

 

Right-click an item in the table to see options. (Not every column offers options.)

Tip


To see additional options, right-click a file SHA in a table on an event page. For information, see Event Investigation Using Web-Based Resources.


File Composition Report

If you configure local malware analysis or dynamic analysis, the system generates a file composition report after analyzing a file. This report allows you to further analyze files and determine whether they may carry embedded malware.

The file composition report lists file properties, any objects embedded in the file, and any detected viruses. The file composition report may also list additional information specific to that file type. When the system prunes stored files, it also prunes the associated file composition report.

To view file composition information, see Using a Network File Trajectory.

View File Details in AMP Private Cloud

If you have deployed an AMP private cloud, you can view additional details about analyzed files in your private cloud.

For more information, see the documentation for your private cloud.

Procedure


Sign in directly to your AMP private cloud console.

The Firepower Management Center caches a file’s threat score for the same amount of time as the file’s disposition. If the system later detects these files, it displays the cached threat scores instead of re-querying the Cisco Threat Grid cloud or an Cisco Threat Grid on-premises appliance. You can automatically assign a malware file disposition to any file with a threat score that exceeds the defined malware threshold threat score.

Dynamic Analysis Summary

If a dynamic analysis summary is available, you can click the threat score icon to view it. If multiple reports exist, this summary is based on the most recent report matching the exact threat score. If none match the exact threat score, the report with the highest threat score is displayed. If more than one report exists, you can select a threat score to view each separate report.

The summary lists each component threat comprising the threat score. Each component threat is expandable to list the AMP cloud findings, as well as any processes related to this component threat.

The process tree shows the processes that started when the Cisco Threat Grid cloud attempted to run the file. This can help identify whether a file that contains malware is attempting to access processes and system resources beyond what is expected (for example, running a Word document opens Microsoft Word, then starts Internet Explorer, then runs the Java Runtime Environment).

Each listed process contains a process identifier you can use to verify the actual process. Child nodes in the process tree represent processes started as a result of parent processes.

From the dynamic analysis summary, you can click View Full Report to view the full Analysis Report, detailing the AMP cloud’s full analysis, including general file information, a more in-depth review of all detected processes, a breakdown of the file analysis, and other relevant information.

Viewing Dynamic Analysis Results in the Cisco Threat Grid Public Cloud

Cisco Threat Grid offers more detailed reporting on analyzed files than is available in the Firepower Management Center. If your organization has an account in the Cisco Threat Grid public cloud, you can access the Cisco Threat Grid portal directly to view additional details about files sent for analysis from your managed devices.

Before you begin

  • Associate your Firepower Management Center with your Cisco Threat Grid public cloud account. See Enabling Access to Dynamic Analysis Results in the Public Cloud.

  • License requirement: Malware

  • You must be in the global domain for this task.

  • You must have one of the following user roles: Admin, Access Admin, Network Admin

Procedure


Step 1

Access the Cisco Threat Grid public cloud portal at the address provided in your Threat Grid documentation.

Step 2

Sign in with the account credentials that you used to create the association in the prerequisites to this task.

Step 3

View files submitted by your organization, or search for a particular file using its SHA.

If you have questions, see the Threat Grid documentation.


Using Captured File Workflows

When a managed device captures a file detected in network traffic, it logs an event.


Note


If a device captures a file containing malware, the device generates two events: a file event when it detects the file, and a malware event when it identifies malware.


Use this procedure to view a list of captured files in a table and manipulate the event view depending on the information relevant to your analysis. The page you see when you access captured files differs depending on the workflow, which is simply a series of pages you can use to evaluate events by moving from a broad to a more focused view. You can also create a custom workflow that displays only the information that matches your specific needs.

If the system recaptures a file after a configuration change, such as an updated file policy, it updates existing information for that file.

For example, if you configure a file policy to capture files with a Malware Cloud Lookup action, the system stores the file disposition and threat score along with the file. Then, if you update your file policy, and the system recaptures the same file due to a new Detect Files action, the system updates the file's Last Changed value. However, the system does not remove the existing disposition and threat score, even though you did not perform another malware cloud lookup.

In a multidomain deployment, you can view data for the current domain and for any descendant domains. You cannot view data from higher level or sibling domains.

Before you begin

You must be an Admin or Security Analyst user to perform this task.

Procedure


Choose Analysis > Files > Captured Files.

Tip

 

In the table view of events, several fields are hidden by default. To show a hidden field in an event view, expand the search constraints, then click the field name under Disabled Columns.


Captured File Fields

The table view of captured files, which is the final page in predefined captured file workflows, and which you can add to custom workflows, includes a column for each field in the captured files table.

When searching this table keep in mind that your search results depend on the available data in the events you are searching; depending on the available data, your search constraints may not apply. For example, if a file has never been submitted for dynamic analysis, it may not have an associated threat score.

Table 7. Captured File Fields

Field

Description

Archive Inspection Status

For archive files, the status of archive inspection:

  • Pending indicates that the system is still inspecting the archive file and its contents. If the file passes through your system again, complete information becomes available.

  • Extracted indicates that the system was able to extract and inspect the archive’s contents.

  • Failed may, in rare cases, occur if the system is unable to process an extraction.

  • Depth Exceeded indicates that the archive contains further nested archive files beyond the maximum allowed depth.

  • Encrypted indicates that the archive file’s contents are encrypted and could not be inspected.

  • Not Inspectable indicates that the system did not extract and inspect the archive’s contents. Policy rule actions, policy configuration, and corrupted files are three major reasons for this status.

To view the contents of an archive file, right-click on its row in the table to bring up the context menu, then choose View Archive Contents.

Category

The general categories of file type, for example: Office Documents, Archive, Multimedia, Executables, PDF files, Encoded, Graphics, or System Files.

Detection Name

The name of the detected malware.

Disposition

The file’s AMP for Networks disposition:

  • Malware indicates that local malware analysis identified malware, the AMP cloud categorized the file as malware, or that the file’s threat score exceeded the malware threshold defined in the file policy.

  • Clean indicates that the AMP cloud categorized the file as clean, or that a user added the file to the clean list.

  • Unknown indicates that the system queried the AMP cloud, but the file has not been assigned a disposition; in other words, the AMP cloud has not categorized the file.

  • Custom Detection indicates that a user added the file to the custom detection list.

  • Unavailable indicates that the system could not query the AMP cloud. You may see a small percentage of events with this disposition; this is expected behavior.

  • N/A indicates a Detect Files or Block Files rule handled the file and the Firepower Management Center did not query the AMP cloud.

Domain

The domain where the captured file was detected. This field is only present if you have ever configured the Firepower Management Center for multitenancy.

Dynamic Analysis Status

One or more of the following values indicating whether the file was submitted for dynamic analysis:

  • Analysis Complete — file submitted for dynamic analysis that received a threat score and dynamic analysis summary report

  • Capacity Handled — file stored because it could not be submitted currently

  • Capacity Handled (Network Issue) — file stored because it could not be submitted due to a network connectivity issue

  • Capacity Handled (Rate Limit) — file stored because it could not be submitted due to the maximum number of submissions reached

  • Device Not Activated — file not submitted because the device is not activated on the on-premises Cisco Threat Grid appliance. If you see this status, contact Support.

  • Failure (Analysis Timeout) — file submitted for which the AMP cloud has yet to return a result

  • Failure (Cannot Run File) — file submitted that the AMP cloud could not run in the test environment

  • Failure (Network Issue) — file that did not get submitted due to a network connectivity failure

  • Not Sent for Analysis — file not submitted

  • Not Suspicious (Not Sent For Analysis) — file pre-classified as non-malware

  • Previously Analyzed — file with a cached threat score, indicating that it has been previously sent

  • Sent for Analysis — file pre-classified as malware and queued for dynamic analysis

Dynamic Analysis Status Changed

The last time the file's dynamic analysis status changed.

File Name

The most recently detected file name associated with the file’s SHA-256 hash value.

Last Changed

The last time the information associated with this file was updated.

Last Sent

The time the file was most recently submitted to the AMP cloud for dynamic analysis.

Local Malware Analysis Status

One of the following values indicating whether the system performed local malware analysis on a file:

  • Analysis Complete — the system inspected the file using local malware analysis and pre-classified the file

  • Analysis Failed — the system attempted to inspect the file using local malware analysis and failed

  • Manual Request Submitted — a user submitted a file for local malware analysis

  • Not Analyzed — the system did not inspect the file with local malware analysis

SHA256

The SHA-256 hash value of the file, as well as a network file trajectory icon representing the most recently detected file event and file disposition. To view the network file trajectory, click the trajectory icon.

Storage Status

Indicates whether the file is stored on a managed device:

  • File Stored

  • Not Stored (Disposition Was Pending)

Threat Score

The threat score most recently associated with this file.

To view the Dynamic Analysis Summary report, click the threat score icon.

Type

The type of file; for example, HTML or MSEXE.

Stored Files Download

Once a device stores a file, as long as the Firepower Management Center can communicate with that device and it has not deleted the file, you can download the file to a local host for long-term storage and analysis, and manually analyze the file. You can download a file from any associated file event, malware event, captured file view, or the file’s trajectory.

Because malware is harmful, by default, you must confirm every file download. However, you can disable the confirmation in your User Preferences.

Because files with a disposition of Unknown may contain malware, when you download a file, the system first archives the file in a .zip package. The .zip file name contains the file disposition and file type, if available, and SHA-256 hash value. You can password-protect the .zip file to prevent accidental unpacking. You can edit or remove the default .zip file password in your User Preferences.


Caution


Cisco strongly recommends you do not download malware, as it can cause adverse consequences. Exercise caution when downloading any file, as it may contain malware. Ensure you have taken any necessary precautions to secure the download destination before downloading files.


Manually Submit Files for Analysis

When you manually submit files for analysis, the system runs local analysis, then submits these files to the cloud for dynamic analysis. However, if local analysis is not enabled in a file policy, and you manually submit a file for analysis, the file will only be sent for dynamic analysis.

In addition to executable files, you can also submit file types not eligible for automatic submission, such as .swf, .jar, and others. This allows you to more quickly analyze a broad range of files, regardless of disposition, and pinpoint the exact causes of an incident.


Note


The system checks the AMP cloud for updates (no more than once a day) to the list of file types eligible for dynamic analysis and the minimum and maximum file sizes you can submit.


Depending on the situation, there are two ways to submit files for analysis:

Before you begin

In order to manually submit captured files for analysis, one or more file rules must be configured to store files. For information, see File Policies and Malware Protection.

Procedure


Step 1

To submit a single file for analysis:

  1. Select one of the following:

    • Analysis > Files > File Events

    • Analysis > Files > Malware Events

    • Analysis > Files > Captured Files

  2. Click Table View of <Event type or files>.

  3. Right-click a file in the table and select Analyze File.

Step 2

To submit multiple captured files for analysis (up to 25 at a time):

  1. Select Analysis > Files > Captured Files

  2. Select the checkbox beside each file to analyze.

  3. Click Analyze.


Network File Trajectory

The network file trajectory feature maps how hosts transferred files, including malware files, across your network. A trajectory charts file transfer data, the disposition of the file, and if a file transfer was blocked or the file was quarantined. You can determine which hosts and users may have transferred malware, which hosts are at risk, and observe file transfer trends.

You can track the transmission of any file with a AMP cloud-assigned disposition. The system can use information related to detecting and blocking malware from both AMP for Networks and AMP for Endpoints to build the a trajectory.

Recently Detected Malware and Analyzed Trajectories

The Network File Trajectory List page displays the malware most recently detected on your network, as well as the files whose trajectory maps you have most recently viewed. From these lists, you can view when each file was most recently seen on the network, the file’s SHA-256 hash value, name, type, current file disposition, contents (for archive files), and the number of events associated with the file.

The page also contains a search box that lets you locate files, either based on SHA-256 hash value or file name, or by the IP address of the host that transferred or received a file. After you locate a file, you can click the File SHA256 value to view the detailed trajectory map.

Network File Trajectory Detailed View

You can trace a file through the network by viewing the detailed network file trajectory. Search for a file's SHA 256 value or click a File SHA 256 link in the Network File Trajectory list to view details about that file.

The network file trajectory details page has three parts:

  • Summary Information — A file’s trajectory page displays summary information about the file, including file identification information; when the file was first seen and most recently seen on the network, and by what user; the number of related events and hosts associated with the file; and the file’s current disposition. From this section, if the managed device stored the file, you can download it locally, submit the file for dynamic analysis, or add the file to a file list.

  • Trajectory Map — A file’s trajectory map visually tracks a file from the first detection on your network to the most recent. The map shows when hosts transferred or received the file, how often they transferred the file, and when the file was blocked or quarantined. Vertical lines between data points represent file transfers between hosts. Horizontal lines connecting the data points show a host’s file activity over time.

    The map also shows how often file events occurred for the file and when the system assigned the file a disposition or retrospective disposition. You can select a data point in the map and highlight a path that traces back to the first instance the host transferred that file; this path also intersects with every occurrence involving the host as either sender or receiver of the file, and identifies the user involved.

  • Related Events — The Events table lists event information for each data point in the map. Using the table and the map, you can pinpoint specific file events, hosts and users on the network that transferred or received this file, related events in the map, and other related events in a table constrained on selected values.

Network File Trajectory Summary Information

The following summary information appears at the top of the details page for a file that appears in the Network File Trajectory list.


Tip


To view related file events, click a field value link. The first page in the File Events default workflow opens in a new window, displaying all file events that also contain the selected value.


Table 8. Network File Trajectory Summary Information Fields

Name

Description

Archive Contents

For inspected archive files, the number of files the archive contains.

Current Disposition

One of the following AMP for Networks file dispositions:

  • Malware indicates that the AMP cloud categorized the file as malware, local malware analysis identified malware, or the file’s threat score exceeded the malware threshold defined in the file policy.

  • Clean indicates that the AMP cloud categorized the file as clean, or that a user added the file to the clean list.

  • Unknown indicates that the system queried the AMP cloud, but the file has not been assigned a disposition; in other words, the AMP cloud has not categorized the file.

  • Custom Detection indicates that a user added the file to the custom detection list.

  • Unavailable indicates that the system could not query the AMP cloud. You may see a small percentage of events with this disposition; this is expected behavior.

  • N/A indicates a Detect Files or Block Files rule handled the file and the Firepower Management Center did not query the AMP cloud.

Detection Name

Name of the malware detected by local malware analysis.

Event Count

The number of events seen on the network associated with the file, and the number of events displayed in the map if there are more than 250 detected events.

File Category

The general categories of file type, for example, Office Documents or System Files.

File Names

The names of the file associated with the event, as seen on the network.

If multiple file names are associated with a SHA-256 hash value, the most recent detected file name is listed. You can expand this to view the remaining file names by clicking more.

File SHA256

The SHA-256 hash value of the file.

The hash is displayed by default in a condensed format. To view the full hash value, hover your pointer over it. If multiple SHA-256 hash values are associated with a file name, hover your pointer over the link to view all of the hash values.

File Size (KB)

The size of the file, in kilobytes.

File Type

The file type of the file, for example, HTML or MSEXE.

First Seen

The first time AMP for Networks or AMP for Endpoints detected the file, as well as the IP address of the host that first uploaded the file and identifying information for the user involved.

Last Seen

The most recent time AMP for Networks or AMP for Endpoints detected the file, as well as the IP address of the host that last downloaded the file and identifying information for the user involved.

Parent Application

The client application accessing the malware file when detection occurred by AMP for Endpoints. These applications are not tied to network discovery or application control.

Seen On

The number of hosts that either sent or received the file. Because one host can upload and download a file at different times, the total number of hosts may not match the total number of senders plus the total number of receivers in the Seen On Breakdown field.

Seen On Breakdown

The number of hosts that sent the file, followed by the number of hosts that received the file.

Threat Name

Name of the threat associated with the detected malware by AMP for Endpoints.

Threat Score

The file’s threat score.

Network File Trajectory Map and Related Events List

The file trajectory map’s y-axis contains a list of all host IP addresses that have interacted with the file. The IP addresses are listed in descending order based on when the system first detected the file on that host. Each row contains all events associated with that IP address, whether a single file event, file transfer, or retrospective event. The x-axis contains the date and time the system detected each event. The timestamps are listed in chronological order. If multiple events occurred within a minute, all are listed within the same column. You can scroll the map horizontally and vertically to view additional events and IP addresses.

The map displays up to 250 events associated with the file SHA-256 hash. If there are more than 250 events, the map displays the first 10, then truncates extra events with an Arrow. The map then displays the remaining 240 events.

The first page of the File Events default workflow appears in a new window with all the extra events constrained based on the file type. If malware events generated by AMP for Endpoints are not displayed, you must switch to the Malware Events table to view these.

Each data point represents an event plus the file disposition, as described in the legend below the map. For example, a Malware Block event icon combines the Malicious Disposition icon and the Block Event icon.

Malware events generated by AMP for Endpoints ("endpoint-based malware events") include one icon. A retrospective event displays an icon in the column for each host on which the file is detected. File transfer events always include two icons, one file send icon and one file receive icon, connected by a vertical line. Arrows indicate the file transfer direction from sender to receiver.

To track a file’s progress through the network, you can click any data point to highlight a path that includes all data points related to the selected data point. This includes data points associated with the following types of events:

  • any file transfers in which the associated IP address was either sender or receiver

  • any malware events generated by AMP for Endpoints ("endpoint-based malware events") involving the associated IP address

  • if another IP address was involved, all file transfers in which that associated IP address was either sender or receiver

  • if another IP address was involved, any malware events generated by AMP for Endpoints ("endpoint-based malware events") involving the other IP address

All IP addresses and timestamps associated with any highlighted data point are also highlighted. The corresponding event in the Events table is also highlighted. If a path includes truncated events, the path itself is highlighted with a dotted line. Truncated events might intersect the path, but are not displayed in the map.

Using a Network File Trajectory

In a multidomain deployment, you can view data for the current domain and for any descendant domains. You cannot view data from higher level or sibling domains.


Tip


If your organization has deployed AMP for Endpoints, that product also has a network file trajectory feature. To pivot from FMC to AMP for Endpoints, see Work with Event Data in the AMP for Endpoints Console. For details about the file trajectory feature in AMP for Endpoints, see the AMP for Endpoints documentation.
