Dependencies
  • Network Attack Defense depends on the iptables Linux package. You need to manually install the package on all endpoints where the NAD module is to be deployed.

    The package is available for all supported distributions:

    Fo Debian based operating systems:

    apt install -y iptables

    For Red Hat based operating systems

     dnf install -y iptables

    For SUSE operating systems:

    zypper install iptables
  • Network Attack Defense uses port 8887 by default. If the port is already in use, NAD does not switch to another port dynamically. You need to make sure that the port is not in use.

Setting up iptables rules

Installing the product also delivers a series of scripts that are used to configure iptables rules and route traffic for our products. This is done to detect and monitor connections on ports 21 and 22.

Network Attack Defense sorts and runs these executable scripts passing the stop or start argument. They are located under /opt/bitdefender-security-tools/etc/nad.d/.

Note

You can add your own custom iptables scripts under the /opt/bitdefender-security-tools/etc/nad.d/ folder. They must support stop and start arguments.

Scripts are sorted based on their file name. They run in alphabetical order and stop in reversed order. Take this into consideration when naming your custom scripts.
