## Overview

The Cisco Firepower Threat Defense (FTD) integration for Elastic collects logs from Cisco FTD devices, enabling comprehensive monitoring, threat detection, and security analysis within the Elastic Stack. This integration parses syslog messages from Cisco FTD, providing real-time visibility into network traffic, security events, and system activity. By centralizing these logs, you can enhance your security posture, streamline incident response, and gain deep insights into your network's operations.

### Compatibility

This integration is compatible with Cisco FTD devices that support syslog export. It requires Elastic Stack version 8.11.0 or newer.

### How it works

The integration works by receiving syslog data sent from a Cisco FTD device. Elastic Agent can be configured to listen for these logs on a specific TCP or UDP port, or to read them directly from a log file. Once received, the agent processes and parses the logs before sending them to Elasticsearch.

## What data does this integration collect?

The Cisco FTD integration collects logs containing detailed information about:
- **Connection Events**: Firewall traffic, network address translation (NAT), and connection summaries.
- **Security Events**: Intrusion detection and prevention (IPS/IDS) alerts, file and malware protection events, and security intelligence data.
- **System Events**: Device health, system status, and configuration changes.


### Supported use cases

- **Real-time Threat Detection**: Use Elastic SIEM to identify and respond to threats like malware, intrusions, and policy violations.
- **Network Traffic Analysis**: Visualize and analyze network traffic patterns to identify anomalies, troubleshoot connectivity issues, and optimize performance.
- **Security Auditing and Compliance**: Maintain a searchable archive of all firewall activity to support compliance requirements and forensic investigations.
- **Operational Monitoring**: Track the health and status of your FTD devices to ensure they are functioning correctly.


## What do I need to use this integration?

Elastic Agent must be installed on a host that is reachable by your Cisco FTD device over the network. For more details, check the Elastic Agent [installation instructions](https://www.elastic.co/docs/reference/fleet/install-elastic-agents). You can install only one Elastic Agent per host.
Elastic Agent is required to stream data from the syslog or log file receiver and ship the data to Elastic, where the events will then be processed through the integration's ingest pipelines.

## How do I deploy this integration?


### Onboard / configure


#### 1. Configure Cisco FTD to send Syslog Data

You must configure your Cisco FTD device to forward syslog messages to the Elastic Agent. The specific steps may vary depending on whether you are using Firepower Device Manager (FDM) or Firepower Management Center (FMC).
1. **Define the Elastic Agent as a Syslog Server**:
   - In your FDM or FMC interface, navigate to the syslog configuration section (for example, **Objects > Syslog Servers** or **Device > System Settings > Logging**).
- Add a new syslog server, providing the IP address and port of the machine where the Elastic Agent is running.
- Ensure the protocol (TCP or UDP) matches the input you configure in the integration.
2. **Configure Logging Rules**:
   - Create or edit a logging rule to send specific event classes to the newly configured syslog server.
- It is recommended to send all relevant message IDs to ensure comprehensive data collection.
3. **Deploy Changes**:
   - Save and deploy your configuration changes to the FTD device.

Refer to the Cisco instructions on how to [configure Logging on FTD via FMC](https://www.cisco.com/c/en/us/support/docs/security/firepower-ngfw/200479-Configure-Logging-on-FTD-via-FMC.html).

#### 2. Add the Cisco FTD Integration in Elastic

1. In Kibana, navigate to **Management > Integrations**.
2. In the search bar, enter **Cisco FTD**.
3. Click the integration to see more details and then click **Add integration**.
4. Configure the integration settings. You must select the input method that matches your Cisco FTD configuration (TCP, UDP, or log file).
   - **For TCP/UDP**: Specify the `host` and `port` where the Elastic Agent should listen for syslog messages. This must match the destination you configured on your FTD device.
- **For Log File**: Provide the file `paths` that the agent should monitor.
5. Click **Save and continue** to add the integration policy to an Elastic Agent.


#### 3. Validate that the integration is working

Navigate to the **Discover** tab in Kibana. Filter for the `cisco_ftd.log` dataset (`data_stream.dataset : "cisco_ftd.log"`) and verify that logs from your FTD device are being ingested. You can also check the pre-built dashboards for this integration by searching for "Cisco FTD" in the **Dashboards** section.

## Troubleshooting

1. **Verify Agent Status**:
   - In Kibana, navigate to **Management** > **Fleet** > **Agents**
- Confirm the Elastic Agent shows as "Healthy" and has the Cisco FTD integration assigned
- Check the agent logs for any connection errors
2. **Trigger Test Events**:
   - Generate test network traffic through the FTD device (for example, web browsing, file download)
- Or trigger a security event by accessing a known malicious URL or downloading a test file
- Verify the FTD device is sending syslog messages (check FTD logs or management interface)
3. **Verify Data Ingestion**:
   - In Kibana, navigate to **Discover**
- Select the `logs-cisco_ftd.log-*` data stream
- Verify events are appearing with recent timestamps
- Check that events contain expected fields such as `cisco.ftd.*`, `source.ip`, `destination.ip`, etc.
4. **Validate Event Fields**:
   - Open a sample event and verify:
  - `@timestamp` is correctly parsed
- `cisco.ftd.message_id` is present
- Network fields (`source.ip`, `destination.ip`, `source.port`, `destination.port`) are populated
- Security event fields are present for security-related events
- `event.original` contains the raw syslog message (if preserve_original_event is enabled)
5. **Check for Parsing Errors**:
   - Filter for `event.outcome: failure` or check for `error.message` fields
- Review any events with parsing issues
- Verify timezone configuration if timestamps appear incorrect

For help with Elastic ingest tools, check [Common problems](https://www.elastic.co/docs/troubleshoot/ingest/fleet/common-problems).
A field named `cisco.ftd.security` contains a variable number of sub-fields, which is mapped as a [`flattened` datatype](https://www.elastic.co/guide/en/elasticsearch/reference/current/flattened.html). This mapping limits certain operations, such as aggregations, on its sub-fields.
To enable aggregations on common security-related fields, the integration automatically moves a known set of fields from `cisco.ftd.security` to a new field, `cisco.ftd.security_event`. If you need to perform aggregations on additional fields within `cisco.ftd.security`, you can create a custom ingest pipeline to move them.
To create this custom pipeline:
1. In Kibana, navigate to **Stack Management > Ingest Pipelines**.
2. Click **Create Pipeline > New Pipeline**.
3. Set the `Name` to `logs-cisco_ftd.log@custom`.
4. Add a **Rename** processor:
   - Set `Field` to the source field, for example, `cisco.ftd.security.threat_name`.
- Set `Target field` to the destination, for example, `cisco.ftd.security_event.threat_name`.
5. Add more processors as needed and save the pipeline. This `@custom` pipeline will be automatically applied to all incoming Cisco FTD logs.

  | destination.address                                       | Some event destination addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket.  You should always store the raw address in the `.address` field. Then it should be duplicated to `.ip` or `.domain`, depending on which one it is.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           | keyword          |

Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk".                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           | keyword          |

  | event.code                                                | Identification code for this event, if one exists.

  | event.created                                             | `event.created` contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from `@timestamp` in that `@timestamp` typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, `@timestamp` should be used.                                                                                                                                                                                                                                                                                            | date             |

  | event.outcome                                             | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. `event.outcome` simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of `event.outcome`, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with `event.type:info`, or any events for which an outcome does not make logical sense. | keyword          |
  | event.provider                                            | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      | keyword          |

This describes the why of a particular action or outcome captured in the event. Where `event.action` captures the action from the event, `event.reason` describes why that action was taken. For example, a web proxy with an `event.action` which denied the request may also populate `event.reason` with the reason why (e.g. `blocked site`).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              | keyword          |

What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in `log.syslog.severity.code`. `event.severity` is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the `log.syslog.severity.code` to `event.severity`.                                                                                                                                                                                                                                                                                                                                                   | long             |

  | event.type                                                | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. `event.type` represents a categorization "sub-bucket" that, when used along with the `event.category` field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          | keyword          |

  | network.direction                                         | Direction of the network traffic. When mapping events from a host-based monitoring context, populate this field from the host's point of view, using the values "ingress" or "egress". When mapping events from a network or perimeter-based monitoring context, populate this field from the point of view of the network perimeter, using the values "inbound", "outbound", "internal" or "external". Note that "internal" is not crossing perimeter boundaries, and is meant to describe communication between two hosts within the perimeter. Note also that "external" is meant to describe traffic between two hosts that are external to the perimeter. This could for example be useful for ISPs or VPN service providers.                                                                                                                                                                                      | keyword          |

In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the `domain` field. If the URL contains a literal IPv6 address enclosed by `[` and `]` (IETF RFC 2732), the `[` and `]` characters should also be captured in the `domain` field.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    | keyword          |
  | url.extension                                             | The field contains the file extension from the original request url, excluding the leading dot. The file extension is only set if it exists, as not every url has a file extension. The leading period must not be included. For example, the value must be "png", not ".png". Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz").                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | keyword          |
