Collect AIDE (Advanced Intrusion Detection Environment) logs

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

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

Get Google SecOps customer ID

1. Sign in to the Google SecOps console.
2. Go to SIEM Settings > Profile.
3. Copy and save the Customer IDfrom the Organization Detailssection.

Install the Bindplane agent

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

Linux installation

1. Open a terminal with root or sudo privileges.

2. 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

1. Access the configuration file:

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

2. 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 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 
  

Configure Syslog forwarding on AIDE

1. Open the AIDE configuration file:

    sudo  
   vi  
   /etc/aide/aide.conf 
   

2. Go to the reporting section.

3. 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:

       report_level 
      = 
      list_entries 
      report_format 
      = 
      json 
      report_url 
      = 
      syslog:authpriv 
      
     

4. Save the configuration.

5. Configure rsyslog to forward AIDE logs to the Bindplane agent. Open the rsyslog configuration:

    sudo  
   vi  
   /etc/rsyslog.d/aide-forward.conf 
   

6. 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.

7. Restart rsyslog:

    sudo  
   systemctl  
   restart  
   rsyslog 
   

8. 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 
   

9. Test the configuration:

    sudo  
   aide  
   --check 
   

10. Set up automated checks using cron:

     sudo  
    crontab  
    -e 
    

11. Add the following line to run AIDE daily at 04:05 AM:

      05 
      
     4 
      
     * 
      
     * 
      
     * 
      
     root 
      
     / 
     usr 
     / 
     sbin 
     / 
     aide 
      
     -- 
     check
