Result of scanning VyOS 1.4-rolling-202309040919 using Lynis 3.0.8 (package from debian bookworm).

For more information see:

Note that the testresult below was obtained by adding this to /etc/apt/sources.list:

deb http://ftp.se.debian.org/debian bookworm main

Followed by:

sudo apt-get update
sudo apt-get install lynis
sudo lynis audit system

Also note that not all recommendations are valid (for example that some apt sources are missing which they are supposed to be missing (all of them) in VyOS iso).
