Collect Cisco Wireless Security Management (WiSM) logs

Supported in:

Google secops SIEM

This document explains how to ingest Cisco Wireless Security Management (WiSM) logs to Google Security Operations using Bindplane. The parser extracts fields from the syslog messages, maps them to the Unified Data Model (UDM), and categorizes events based on the cisco_mnemonic field. It handles various event types like logins, logouts, network connections, and status updates, extracting relevant information like usernames, IP addresses, MAC addresses, and security details.

Before you begin

Make sure you have the following prerequisites:

Google SecOps instance
A Windows 2016 or later, or a Linux host with systemd
If running behind a proxy, ensure firewall ports are open
Privileged access to Cisco Wireless LAN COntroller (WLC)

Get Google SecOps ingestion authentication file

Sign in to the Google SecOps console.
Go to SIEM Settings > Collection Agents.
Download the Ingestion Authentication File.
- Save the file securely on the system where BindPlane will be installed.

Get Google SecOps customer ID

Sign in to the Google SecOps console.
Go to SIEM Settings > Profile.
Copy and save the Customer ID from the Organization Details section.

Install the Bindplane agent

Install the Bindplane agent on your Windows or Linux operating system according to the following instructions.

Windows installation

Open the Command Prompt or PowerShell as an administrator.

Run the following command:

msiexec /i "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" /quiet

Linux installation

Open a terminal with root or sudo privileges.

Run the following command:

sudo sh -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh

Additional installation resources

For additional installation options, consult the installation guide.

Configure the Bindplane agent to ingest Syslog and send to Google SecOps

Access the configuration file:
- Locate the config.yaml file. Typically, it's in the /etc/bindplane-agent/ directory on Linux or in the installation directory on Windows.
- Open the file using a text editor (for example, nano, vi, or Notepad).

Edit the config.yaml file as follows:

receivers:
    udplog:
        # Replace the port and IP address as required
        listen_address: "0.0.0.0:514"

exporters:
    chronicle/chronicle_w_labels:
        compression: gzip
        # Adjust the path to the credentials file you downloaded in Step 1
        creds_file_path: '/path/to/ingestion-authentication-file.json'
        # Replace with your actual customer ID from Step 2
        customer_id: <customer_id>
        endpoint: malachiteingestion-pa.googleapis.com
        # Add optional ingestion labels for better organization
        log_type: 'CISCO_WSM'
        raw_log_field: body
        ingestion_labels:

service:
    pipelines:
        logs/source0__chronicle_w_labels-0:
            receivers:
                - udplog
            exporters:
                - chronicle/chronicle_w_labels

Replace the port and IP address as required in your infrastructure.
Replace <customer_id> with the actual customer ID.
Update /path/to/ingestion-authentication-file.json to the path where the authentication file was saved in the Get Google SecOps ingestion authentication file section.

Restart the Bindplane agent to apply the changes

To restart the Bindplane agent in Linux, run the following command:
```
sudo systemctl restart bindplane-agent
```
To restart the Bindplane agent in Windows, you can either use the Services console or enter the following command:
```
net stop BindPlaneAgent && net start BindPlaneAgent
```

Configure Syslog on Cisco WiSM

Sign in to the Cisco Wireless LAN Controller web UI.
Go to Management > Logs > Config.
Enter the Bindplane agent IP address in the Syslog Server IP Address field.
Click Add.
Provide the following configuration details:
- Syslog Severity: Select Informational.
- Syslog Facility: Select Local Use 0.
- Buffered Log Level: Select Informational - Severity level 6.
- Console Log Level: Select Informational - Severity level 6.
- Select the File Info checkbox to include information about the source file.
- Select the Proc Info checkbox to include process information.
- Select the Trace Info checkbox to include trace back information.
Click Apply.
Click Save Configuration.

UDM mapping table

Log Field	UDM Mapping	Logic
`cisco_facility`	`principal.resource.type`	Extracted from the `cisco_tag` field using grok.
