Collect Cisco Prime logs

Supported in:

Google secops SIEM

This document explains how to ingest Cisco Prime logs to Google Security Operations using Bindplane. The parser utilizes Grok patterns to extract fields from various syslog message formats, mapping them to a Unified Data Model (UDM). It handles different log structures, including key-value pairs, and enriches the data with user, principal, target, and security information based on specific keywords and patterns found within the log messages.

Before you begin

Make sure you have the following prerequisites:

Google SecOps instance
Windows 2016 or later, or a Linux host with systemd
If running behind a proxy, ensure firewall ports are open
Privileged access to Cisco Prime

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 IDfrom the Organization Detailssection.

Install Bindplane agent

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

Windows installation

Open the Command Promptor PowerShellas 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 
 :

 : 
  
 gzip 
  
 # Adjust the path to the credentials file you downloaded in Step 1 
  
 creds_file_path 
 :

 # Replace with your actual customer ID from Step 2

 : 
  
 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 Servicesconsole or enter the following command:
```
 net stop BindPlaneAgent && net start BindPlaneAgent 
```

Configure change audit notifications and configure syslog receivers

You can configure the system to send syslog notifications for change audits related to the following events:
- Device inventory updates
- Configuration modifications
- Changes to configuration templates
- Template-related operations
- User activities such as logins, logouts, and account modifications
Sign in to the Cisco Prime web UI.
Go to Administration > Settings > System Settings.
Select Mail and Notification > Change Audit Notification.
Click Enable Change Audit Notificationcheckbox.
Click the +button to specify a syslog server.
Provide the following configuration details:
- Enter the Bindplane agent IP address.
- Select the UDPprotocol.
- Enter the Bindplane agent port number.
Click Save.

Configure forwarding system audit logs As syslog

Sign in to the Cisco Prime web UI.
Go to Administration > Settings > Logging > Syslog Logging Options.
Click the Enable Syslogcheckbox.
Provide the following configuration details:
- Enter the Bindplane agent IP address.
- Select the UDPprotocol.
- Enter the Bindplane agent port number.
- Select one of the eight Facilitiesor local0 .
Click Save.
