I have dug around and found the following additions that may be helpful for checking and maintaining a heightened state of system security.

ipfwGUI -- A very simple GUI for the ipfw packet filter (AKA firewall) for FreeBSD
https://github.com/bsdlme/ipfwGUI

pkg audit -- audit installed packages against known vulnerabilities
lynis -- A Security and system auditing tool
vuls -- Agentless vulnerability scanner
clamav -- Command line virus scanner written entirely in C
clamtk -- GTK front-end for Clam Antivirus

Any other suggestions for the current version of Ghost?

For AV I use f-prot.
Run from a terminal with
# sudo fpscan [directory to scan]
You can exclude folders with the switch --exclude [directory not to scan]
Update with
# sudo fpupdate
