Collect Palo Alto Prisma Access CASB logs

Supported in:

Google secops SIEM

This document explains how you can ingest Palo Alto Prisma Access CASB logs to Google Security Operations using the Bindplane agent.

Palo Alto Networks SaaS Security (also known as Next-Generation CASB) is a cloud-delivered Cloud Access Security Broker integrated with Prisma Access. It provides visibility and control over sanctioned and unsanctioned SaaS applications, detects data policy violations, monitors user activity, and remediates risks across cloud services. Data Security, part of SaaS Security, generates logs for incidents, policy violations, remediation activities, activity monitoring, admin audit events, and behavior threats.

Before you begin

Make sure you have the following prerequisites:

A Google SecOps instance
Windows Server 2016 or later, or Linux host with systemd
Network connectivity between the Bindplane agent and the Palo Alto Networks SaaS Security service
If running behind a proxy, make sure firewall ports are open per the Bindplane agent requirements
Palo Alto Networks SaaS Security (Data Security) license, CASB-X license, or CASB-PA license
Administrative access to Strata Cloud Manager with permissions to configure SaaS Security settings
A valid TLS certificate on the syslog server (Data Security requires TLS for syslog connections)

Get a Google SecOps ingestion authentication file

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

Note: This JSON file contains credentials for authenticating the Bindplane agent to Google SecOps.

Get a 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.

Note: The customer ID is required for configuring the Bindplane agent exporter.

Install the Bindplane agent

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

Windows installation

Open 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

Wait for the installation to complete.
Verify the installation by running:
```
sc query observiq-otel-collector
```
The service should show as RUNNING.

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

Wait for the installation to complete.
Verify the installation by running:
```
sudo systemctl status observiq-otel-collector
```
The service should show as active (running).

Additional installation resources

For additional installation options and troubleshooting, see the Bindplane agent installation guide.

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

Locate the configuration file

Linux:

sudo nano /opt/observiq-otel-collector/config.yaml

Windows:

notepad "C:\Program Files\observIQ OpenTelemetry Collector\config.yaml"

Edit the configuration file

Replace the entire contents of config.yaml with the following configuration:

receivers:
  tcplog:
    listen_address: "0.0.0.0:6514"
    tls:
      cert_file: '/etc/bindplane-agent/server.crt'
      key_file: '/etc/bindplane-agent/server.key'

exporters:
  chronicle/pan_casb:
    compression: gzip
    creds_file_path: '/etc/bindplane-agent/ingestion-auth.json'
    customer_id: '<customer_id>'
    endpoint: malachiteingestion-pa.googleapis.com
    log_type: PAN_CASB
    raw_log_field: body
    ingestion_labels:
      vendor: palo_alto_networks
      product: saas_security_casb

service:
  pipelines:
    logs/pan_casb_to_chronicle:
      receivers:
        - tcplog
      exporters:
        - chronicle/pan_casb

Configuration parameters

Replace the following placeholders:

Receiver configuration:
- listen_address: Set to 0.0.0.0:6514 to listen on all interfaces on port 6514 (standard syslog-over-TLS port).
- cert_file: Path to the TLS certificate file for the Bindplane agent.
- key_file: Path to the TLS private key file for the Bindplane agent.
Exporter configuration:
- creds_file_path: Full path to ingestion authentication file:
  - Linux: /etc/bindplane-agent/ingestion-auth.json
  - Windows: C:\Program Files\observIQ OpenTelemetry Collector\ingestion-auth.json
- customer_id: Your Google SecOps customer ID.
- endpoint: Regional endpoint URL:
  - US: malachiteingestion-pa.googleapis.com
  - Europe: europe-malachiteingestion-pa.googleapis.com
  - Asia: asia-southeast1-malachiteingestion-pa.googleapis.com
  - See Regional Endpoints for complete list
- log_type: Must be exactly PAN_CASB
- ingestion_labels: Optional labels to categorize logs

Save the configuration file

After editing, save the file:

Linux: Press Ctrl+O, then Enter, then Ctrl+X
Windows: Click File > Save

Restart the Bindplane agent to apply the changes

Linux

To restart the Bindplane agent in Linux, run the following command:

sudo systemctl restart observiq-otel-collector

Verify the service is running:

sudo systemctl status observiq-otel-collector

Check logs for errors:

sudo journalctl -u observiq-otel-collector -f

Windows

To restart the Bindplane agent in Windows, choose one of the following options:
- Command Prompt or PowerShell as administrator:
```
net stop observiq-otel-collector && net start observiq-otel-collector
```
- Services console:
  1. Press Win+R, type services.msc, and press Enter.
  2. Locate observIQ OpenTelemetry Collector.
  3. Right-click and select Restart.
  4. Verify the service is running:
```
sc query observiq-otel-collector
```
  5. Check logs for errors:
```
type "C:\Program Files\observIQ OpenTelemetry Collector\log\collector.log"
```

Configure Palo Alto Networks SaaS Security syslog forwarding

To forward SaaS Security Data Security logs to the Bindplane agent, configure a syslog receiver in Strata Cloud Manager.

Prepare a TLS certificate on the Bindplane agent host

Data Security requires TLS-encrypted syslog connections. Before configuring the syslog receiver, prepare the TLS certificate on the Bindplane agent host:

Self-sign or obtain a TLS certificate for the Bindplane agent host.
Place the certificate and private key files on the Bindplane agent host (for example, /etc/bindplane-agent/server.crt and /etc/bindplane-agent/server.key).
Ensure the Bindplane agent configuration references these files in the tls section of the receiver.

Configure syslog receiver in Strata Cloud Manager

Log in to Strata Cloud Manager.
Go to Configuration > SaaS Security > Settings > Directory & External Services > External Services.
Click Add Syslog/API Client.
Select Syslog Receiver to create a syslog server profile.
In the Name field, enter a descriptive name for the profile (for example, Chronicle-Bindplane).
Provide the following configuration details:
- Server IP: Enter the IP address of the Bindplane agent host.
- Port: Enter 6514.
- Facility: Select a syslog standard value (for example, LOG_USER) to calculate the priority (PRI) field. Values can be LOG_USER or LOG_LOCAL0 through LOG_LOCAL7.
- Message format: Select IETF.
Click Save to save the syslog receiver configuration.

Note: Data Security supports only one syslog receiver at a time. If you already have a syslog receiver configured, you must remove it before adding a new one. TCP is required as the reliable transport. The IETF message format is recommended for TCP and TLS connections.

Verify syslog forwarding

After saving the syslog receiver configuration, Data Security will begin forwarding the following log types to the Bindplane agent:

Incidents log
Policy Violation log
Remediation log
Activity Monitoring log
Admin Audit log
Behavior Threats log

Note: Logs are forwarded in comma-separated value (CSV) format. It may take a few minutes for logs to appear in Google SecOps after configuration.

For more information, see Configure Syslog Monitoring on Data Security and Syslog Integration on Data Security.
