Collect AIDE (Advanced Intrusion Detection Environment) logs

Supported in:

Google secops SIEM

This document explains how to ingest AIDE (Advanced Intrusion Detection Environment) logs to Google Security Operations using Bindplane. AIDE is a file integrity monitoring tool that detects changes to files on Linux/Unix systems.

Before you begin

Make sure you have the following prerequisites:

A Google SecOps instance
A Linux host with systemd running AIDE version 0.18 or later (for JSON format support)
If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
Privileged access to the AIDE configuration files

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 Linux operating system according to the following instructions.

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 this 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.
- Open the file using a text editor (for example, nano or vi).

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: 'AIDE'
    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 file path where the authentication file was saved in Step 1.

Restart the Bindplane agent to apply the changes

To restart the Bindplane agent in Linux, run the following command:
```
sudo systemctl restart observiq-otel-collector
```

Configure Syslog forwarding on AIDE

Open the AIDE configuration file:
```
sudo vi /etc/aide/aide.conf
```
Go to the reporting section.
Add the following configuration:
- report_level: Enter list_entries.
- report_format: Enter json (for AIDE 0.18+) or plain.
- report_url: Enter syslog:authpriv.
Example configuration:
```
```ini
report_level=list_entries
report_format=json
report_url=syslog:authpriv
```
```
Save the configuration.
Configure rsyslog to forward AIDE logs to the Bindplane agent. Open the rsyslog configuration:
```
sudo vi /etc/rsyslog.d/aide-forward.conf
```
Add the following configuration to forward authpriv facility logs to the Bindplane agent:
```
authpriv.* @<BINDPLANE_AGENT_IP>:514
```
- Replace <BINDPLANE_AGENT_IP> with the IP address of the Bindplane agent host.
- Use @ for UDP or @@ for TCP forwarding.
Restart rsyslog:
```
sudo systemctl restart rsyslog
```

Initialize the AIDE database if this is a fresh installation:

sudo aide --init
sudo mv /var/lib/aide/aide.db.new /var/lib/aide/aide.db

Test the configuration:
```
sudo aide --check
```
Set up automated checks using cron:
```
sudo crontab -e
```
Add the following line to run AIDE daily at 04:05 AM:
```
05 4 * * * root /usr/sbin/aide --check
```
