Requirements before start
  • RaspberryPI OS (32 or 64 bits);
  • Make sure you have a monitor, mouse and keyboard connected in the device, at least until you get SSH access to it.
Required softwares
  • Raspberry PI ARM ONA image
  • CERT NetSA Security Suite (Silk and YAF)
Step by step installation
  1. Download the .deb for ONA and tar.gz's for SILK and YAF:
cd /tmp
wget https://assets-production.obsrvbl.com/ona-packages/obsrvbl-ona/v5.1.2/ona-service_RaspbianJessie_armhf.deb
wget https://tools.netsa.cert.org/releases/silk-3.19.2.tar.gz
wget https://tools.netsa.cert.org/releases/yaf-2.12.1.tar.gz
  1. Install dependencies for compiling SILK and YAF:
sudo apt-get install build-essential libglib2.0-dev libfixbuf-dev libpcap-dev
  1. Create ONA dirs for SILK and YAF binaries:
sudo mkdir /opt/silk /opt/yaf
  1. Compile and install SILK:
tar -xvzf silk-3.19.2.tar.gz
cd silk-3.19.2
./configure --prefix=/opt/silk --with-libfixbuf
make && sudo make install 
cd ..
  1. Compile and install YAF:
tar -xvzf yaf-2.12.1.tar.gz
cd yaf-2.12.1 
./configure --prefix=/opt/yaf 
make && sudo make install
  1. Install ONA services:
sudo apt install ./ona-service_RaspbianJessie_armhf.deb
  1. After this last step, if you followed the SCA sensor guide, your sensor should be appearing within your SCA dashboard. Wait around 10-20min before the console start to show the netflows
