## Overview

The Juniper SRX integration for Elastic enables you to collect and analyze logs from Juniper SRX Series Firewalls. By ingesting these logs into the Elastic Stack, you gain comprehensive visibility into your network's security posture and operational status. You can use this data to identify threats, monitor traffic patterns, and troubleshoot network issues effectively.

### Compatibility

This integration is compatible with Juniper SRX Series Firewalls running Junos versions that support structured-data logging. Your device must be capable of generating syslog messages in the `structured-data` + `brief` format for successful parsing.

### How it works

This integration collects logs from Juniper SRX firewalls by receiving syslog data over TCP or UDP, or reading a log file. You deploy an Elastic Agent on a host that is configured as a syslog receiver. The agent listens for incoming logs, parses the structured messages, and forwards the data to your Elastic deployment into the `log` data stream. The agent can also watch log files written locally to the Elastic Agent's host. This allows you to visualize and search your security data in real-time.

## What data does this integration collect?

The Juniper SRX integration collects log messages in structured-data format from various security and system processes. It processes the following types of data:
- Firewall session logs: Information on session creation, closing, and denials (`RT_FLOW`).
- Intrusion detection and prevention (IDP) logs: Security screen events and attack log events (`RT_IDS`, `RT_IDP`).
- Unified threat management (UTM) logs: Events related to web filtering, antivirus, and antispam detection (`RT_UTM`).
- Advanced anti-malware logs: Records of malware actions and host infection events (`RT_AAMW`).
- Security intelligence logs: Data related to security intelligence actions (`RT_SECINTEL`).
- Juniper SRX logs: Captures all the security and system processes mentioned above in structured-data format.

The following processes and tags are supported:

### Supported use cases

Integrating your Juniper SRX logs with the Elastic Stack provides several security and operational benefits. You can use this integration for the following:
- Real-time threat monitoring: Identify and respond to threats detected by IDP, UTM, and anti-malware systems as they happen.
- Network visibility: Analyze firewall session data to understand traffic patterns and identify potential bottlenecks or unusual activity.
- Security auditing: Maintain a searchable, long-term archive of security events and intelligence actions to support compliance requirements.
- Incident investigation: Use detailed session and security logs to trace the origin and impact of security incidents across your network.


## What do I need to use this integration?

To collect logs from your Juniper SRX devices, you'll need to meet these vendor-specific requirements:
- Gain administrative access to the Juniper SRX CLI using SSH or a console connection to perform configuration changes.
- Ensure network connectivity exists between the Juniper SRX management or data interfaces and the host running the Elastic Agent.
- Set up firewall rules to allow traffic on the configured syslog port, which defaults to `9006` for this integration.
- Use an SRX device running a Junos version that supports `structured-data` syslog formatting.

You'll also need to prepare your Elastic environment with the following:
- Install and enroll an Elastic Agent in Fleet or configure it to run in standalone mode.
- Install the Juniper SRX integration package in Kibana.
- Ensure network access is available for the agent to receive inbound syslog traffic on your specified port.


## How do I deploy this integration?


### Agent-based deployment

You must install Elastic Agent on a host that can receive syslog data or access log files from your Juniper SRX device. For more details, check the Elastic Agent [installation instructions](https://www.elastic.co/guide/en/fleet/current/elastic-agent-installation.html). You'll only need one Elastic Agent per host.
You'll need the Elastic Agent to stream data from the syslog or log file receiver and ship it to Elastic. From there, the integration's ingest pipelines will process the events.

### Set up steps in Juniper SRX

You can configure your Juniper SRX device to send logs using syslog or write them to a file for collection.

#### Syslog (UDP or TCP) configuration

Follow these steps to configure remote syslog:
1. Log in to the Juniper SRX device using SSH or the console port.
2. Enter configuration mode by typing `configure`.
3. Set the remote syslog destination to the IP address of your Elastic Agent. Replace `<AGENT_IP>` with your agent's IP and `<PORT>` with your configured port (for example, `9006`).
   ```bash
   set system syslog host <AGENT_IP> any any
   set system syslog host <AGENT_IP> port 9006
   ```
4. Configure the mandatory log format. This integration only supports the `structured-data` format with the `brief` option:
   ```bash
   set system syslog host <AGENT_IP> structured-data brief
   ```
5. Set the security logging mode to `event` to ensure security logs are sent to the syslog process:
   ```bash
   set security log mode event
   set security log format syslog
   ```
6. Verify your configuration by running `show system syslog`. Ensure the host entry includes the `structured-data { brief; }` block.
7. Commit your changes by typing `commit`.


#### Log file configuration

Follow these steps to write logs to a local file:
1. Log in to the Juniper SRX device or the intermediate log host.
2. Configure the SRX to write logs to a file using the structured format:
   ```bash
   set system syslog file juniper-srx.log any any
   set system syslog file juniper-srx.log structured-data brief
   ```
3. Ensure the Elastic Agent has read permissions for the file. The default path is `/var/log/juniper-srx.log`.
4. Commit the changes on the SRX device.

### Set up steps in Kibana

You'll need to enable and configure the integration input method that matches your Juniper configuration. Follow the setup instructions that match your configuration.

#### UDP input configuration

This input collects logs over a UDP socket.
1. In Kibana, navigate to **Management > Integrations** and search for **Juniper SRX**.
2. Click **Add Juniper SRX**.
3. Locate the **Collecting syslog from Juniper SRX via UDP** input.
4. Configure the `syslog_host` (default: `localhost`) and `syslog_port` (default: `9006`).
5. If you want to keep the raw log, enable **Preserve original event** to store it in `event.original`.
6. Optionally, configure **Custom UDP Options** like `read_buffer` (default `100MiB`) or `max_message_size` (default `50KiB`).
7. Save the integration to your Agent policy.


#### TCP input configuration

This input collects logs over a TCP socket.
1. In Kibana, navigate to **Management > Integrations** and search for **Juniper SRX**.
2. Click **Add Juniper SRX**.
3. Locate the **Collecting syslog from Juniper SRX via TCP** input.
4. Configure the `syslog_host` (default: `localhost`) and `syslog_port` (default: `9006`).
5. If you're using encryption, configure the **SSL Configuration** settings with your certificate and key.
6. Under **Custom TCP Options**, you can set the `framing` method (default `delimiter`) or `max_connections`.
7. Save the integration to your Agent policy.


#### Log file input configuration

This input collects logs directly from files on the host where the Elastic Agent is running.
1. In Kibana, navigate to **Management > Integrations** and search for **Juniper SRX**.
2. Click **Add Juniper SRX**.
3. Locate the **Collecting syslog from Juniper SRX via file** input.
4. Set the `paths` to the absolute path of your log files (default: `/var/log/juniper-srx.log`).
5. Save the integration to your Agent policy.


### Validation

After you've finished the configuration, verify that data is flowing correctly into Elasticsearch.
To trigger data flow, perform these actions on your Juniper SRX:
- **Generate traffic events**: From a device behind the firewall, visit a website or ping an external IP that matches a logged security policy.
- **Generate configuration events**: Enter configuration mode in the CLI, make a minor change like an interface description, and run `commit`.
- **Generate authentication events**: Log out and back into the SRX CLI or J-Web interface.

To check the data in Kibana:
1. Navigate to **Analytics > Discover**.
2. Select the `logs-*` data view.
3. Filter for `data_stream.dataset: "juniper_srx.log"`.
4. Verify that logs appear and contain expected fields like `event.action`, `source.ip`, or `event.outcome`.
5. Navigate to **Analytics > Dashboards** and search for "Juniper SRX" to see the pre-built visualizations.


## Troubleshooting

For help with Elastic ingest tools, check [Common problems](https://www.elastic.co/docs/troubleshoot/ingest/fleet/common-problems).

### Common configuration issues

You might encounter the following issues when configuring the Juniper SRX integration:
- Missing structured data format: If logs appear in Kibana as a raw string in the `message` field and are not parsed, ensure you've committed the `set system syslog host <IP> structured-data brief` command on the SRX device. This integration requires the `structured-data` format to identify fields.
- Security logs not sent: If you receive system logs but traffic or IDP logs (like `RT_FLOW` or `RT_IDS`) are missing, verify that `set security log mode event` is configured in the Junos CLI. By default, SRX devices might send security logs using the data plane, bypassing system syslog settings.
- Port mismatch: Confirm that the port configured on the Juniper SRX (for example, `set system syslog host <IP> port 9006`) matches the `syslog_port` value in your Elastic Agent integration settings.
- Network connectivity issues: Verify there are no firewalls or network Access Control Lists (ACLs) blocking UDP or TCP traffic on port `9006` between the SRX management interface and the Elastic Agent host.
- Parsing failures: Check the `error.message` field in Kibana. If it contains "Provided Grok expressions do not match", it typically indicates the device is sending logs in standard syslog format instead of the required `structured-data` format.
- Incomplete or truncated logs: If log messages are cut off, you might need to increase the `max_message_size` in the integration's UDP or TCP options to accommodate large structured-data payloads.


## Performance and scaling

To ensure optimal performance in high-volume environments, consider the following:
- Manage your data volume by configuring the Juniper SRX appliance to forward only necessary events, such as `RT_FLOW` or `RT_IDS`, using Junos syslog facility and severity filters. Don't forward excessive debug-level logs at the source because it can overwhelm the ingest pipeline.
- Scale your deployment by placing multiple Elastic Agents behind a network load balancer to distribute the ingestion load in high-throughput environments. You should place agents in close network proximity to the SRX devices to reduce latency and minimize the impact of network congestion on log delivery.

For more information on architectures that can be used for scaling this integration, check the [Ingest Architectures](https://www.elastic.co/docs/manage-data/ingest/ingest-reference-architectures) documentation.

This id normally changes across restarts, but `agent.id` does not.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  | keyword          |
  | agent.id                                   | Unique identifier of this agent (if one exists). Example: For Beats this would be beat.id.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              | keyword          |
  | agent.name                                 | Custom name of the agent. This is a name that can be given to an agent. This can be helpful if for example two Filebeat instances are running on the same host but a human readable separation is needed on which Filebeat instance data is coming from.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                | keyword          |
  | agent.type                                 | Type of the agent. The agent type always stays the same and should be given by the agent used. In case of Filebeat the agent would always be Filebeat also if two Filebeat instances are run on the same machine.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       | keyword          |

Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   | keyword          |
  | dns.question.registered_domain             | The highest registered domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk".                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    | keyword          |
  | dns.question.subdomain                     | The subdomain is all of the labels under the registered_domain.

  | dns.question.top_level_domain              | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk".                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           | keyword          |

  | dns.resolved_ip                            | Array containing all IPs seen in `answers.data`. The `answers` array can be difficult to use, because of the variety of data formats it can contain. Extracting all IP addresses seen in there to `dns.resolved_ip` makes it possible to index them as IP addresses, and makes them easier to visualize and query for.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  | ip               |

  | event.category                             | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. `event.category` represents the "big buckets" of ECS categories. For example, filtering on `event.category:process` yields all events relating to process activity. This field is closely related to `event.type`, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories.                                                                                                                                                                                                                                                                                                                                                                                                                                          | 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.kind                                 | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. `event.kind` gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not.                                                                                                                                                                                                                                                                                                                       | keyword          |

  | 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          |
  | event.reason                               | Reason why this event happened, according to the source. 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          |
  | event.reference                            | Reference URL linking to additional information about this event. This URL links to a static definition of this event. Alert events, indicated by `event.kind:alert`, are a common use case for this field.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             | keyword          |

  | event.risk_score_norm                      | Normalized risk score or priority of the event, on a scale of 0 to 100. This is mainly useful if you use more than one system that assigns risk scores, and you want to see a normalized value across all systems.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      | float            |
  | event.sequence                             | Sequence number of the event. The sequence number is a value published by some event sources, to make the exact ordering of events unambiguous, regardless of the timestamp precision.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  | long             |
  | event.severity                             | The numeric severity of the event according to your event source. 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.start                                | `event.start` contains the date when the event started or when the activity was first observed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         | date             |

It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00").                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | keyword          |
  | 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          |

Successive octets are separated by a hyphen.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            | keyword          |

If multiple messages exist, they can be combined into one message.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             | match_only_text  |
  | network.application                        | When a specific application or service is identified from network connection details (source/dest IPs, ports, certificates, or wire format), this field captures the application's or service's name. For example, the original event identifies the network connection being from a specific web service in a `https` network connection, like `facebook` or `twitter`. The field value must be normalized to lowercase for querying.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  | 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          |

  | process.parent.entity_id                   | Unique identifier for the process. The implementation of this is specified by the data source, but some examples of what could be used here are a process-generated UUID, Sysmon Process GUIDs, or a hash of some uniquely identifying components of a process. Constructing a globally unique identifier is a common practice to mitigate PID reuse as well as to identify a specific process over time, across multiple monitored hosts.                                                                                                                                                                                                                                                                                                                                                                                                                                                                              | keyword          |

  | service.id                                 | Unique identifier of the running service. If the service is comprised of many nodes, the `service.id` should be the same for all nodes. This id should uniquely identify the service. This makes it possible to correlate logs and metrics for one specific service, no matter which particular node emitted the event. Note that if you need to see the events from one specific host of the service, you should filter on that `host.name` or `host.id` instead.                                                                                                                                                                                                                                                                                                                                                                                                                                                      | keyword          |
  | service.name                               | Name of the service data is collected from. The name of the service is normally user given. This allows for distributed services that run on multiple hosts to correlate the related instances based on the name. In the case of Elasticsearch the `service.name` could contain the cluster name. For Beats the `service.name` is by default a copy of the `service.type` field if no name is specified.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                | keyword          |
  | service.node.name                          | Name of a service node. This allows for two nodes of the same service running on the same host to be differentiated. Therefore, `service.node.name` should typically be unique across nodes of a given service. In the case of Elasticsearch, the `service.node.name` could contain the unique node name within the Elasticsearch cluster. In cases where the service doesn't have the concept of a node name, the host name or container name can be used to distinguish running instances that make up this service. If those do not provide uniqueness (e.g. multiple instances of the service running on the same host) - the node name can be manually set.                                                                                                                                                                                                                                                        | keyword          |

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

  | url.domain                                 | Domain of the url, such as "[www.elastic.co](http://www.elastic.co)". 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          |
  | url.fragment                               | Portion of the url after the `#`, such as "top".
