# Cisco ASA

You can configure a **Cisco ASA firewall** to forward logs to the **ThreatDefence Syslog Forwarder** for security monitoring.

***

## Requirements

* A deployed and activated **ThreatDefence Syslog Forwarder VM**
* Administrator access to the Cisco ASA (CLI or ASDM)

***

## Steps

### Step 1. Configure Syslog Settings (CLI)

1. Connect to the Cisco ASA using SSH or console.
2. Enter global configuration mode:

```
configure terminal
```

3. Configure the syslog server:

```
logging host <interface_name> <TD_SYSLOG_FORWARDER_IP> <port>
logging trap informational
logging enable
```

Replace:

* `<interface_name>` with the ASA interface used to reach the Syslog Forwarder (e.g., inside, outside, mgmt).
* `<TD_SYSLOG_FORWARDER_IP>` with the IP of your **ThreatDefence Syslog Forwarder**.
* `<port>` with the appropriate port (as per the [Syslog Onboarding Guide](/appliances/syslog-forwarder/onboarding-syslog-data.md)).

***

### Step 2. Verify Syslog Output

1. Generate test traffic (e.g., VPN login, denied connection).
2. Verify logs are reaching the **ThreatDefence Syslog Forwarder**.

***

### Step 3. Provide Details to ThreatDefence

Once configuration is complete, provide the following details to **ThreatDefence Support** at 📧 [**support@threatdefence.com**](mailto:support@threatdefence.com):

* Firewall make/model and ASA version
* Source IP address and used port number.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.threatdefence.com/siem-integrations/firewalls/cisco-asa.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
