How to Harden Airwave


How to Harden Airwave using Stigs script?


The '' script was defined as a function to harden the AirWave server. Script essentially implements the following:

  • Disables the ability to SSH into the Airwave as 'root', requiring either direct-console access to shell only, or via a created linux local user account (if this is run over SSH, that access will be lost upon reboot, so make sure to create a local user before running. Otherwise, you will have to gain local console access to log in as root to create a local user). From 8.2.4 code default we have  shell local user appadmin and root access is blocked.
  • Creates a GRUB password that prevents the usual GRUB-based password recovery process, as well as makes it much more difficult to access via LiveCDs to make system changes (this means if you lose the GRUB password, recovery is MUCH more difficult and a complete rebuild will be likely)
  • Disables FTP and TFTP (this means if you run the, you will not be able to upgrade controllers or hardware using FTP or TFTP)
  • Disables some preloaded troubleshooting tools (if these are required later, they will have to be added manually)
  • File and folder permissions changes are made
  • Password settings and requirements are changed
  • Some non-essential services are disabled and/or removed
  • Changes to some of the /etc hosts files that may need to be modified to enable more open access (if required)

To run the '' script, one should:

  1. Run from the AirWave CLI as ampadmin (default username, if name is changed during upgrade/installation use that user)

From next login to ampadmin CLI need to login using new password created during applying stig script


Important Note:

  • This effectively makes any kind of OS-based troubleshooting impossible (MIB walks, tcpdumps, etc)
  • After you apply STIGs you will no longer be able to use the amprecovery user account. so do not forget password.
  • It cannot be converted back. If a customer wishes to go back, they will have to pull a nightly backup from the AMP's GUI, and re-build the server from scratch as if the server had failed completely. The standard restore processes apply here.
  • Once the appliance is converted, the installation or update of the VMWare tools is not possible. As such, the use of external NTP is required to maintain time synchronization of the AMP with the rest of the network.
