Security threads

With all this news of Security threats, Ransomware attacks on systems etc. seems a good time to undertake a Security audit on one’s systems - ensure Firewalls are up-to-date, check access policies for systems and volumes (i.e. what’s exposed to the web and how).
Plus check the Backup volumes (my main RAID1 volume has daily backups to RAID1, and JBOD volumes), I then use WinMerge to compare files on the volumes.
Plus update the off-line backup - a USB enclosure with RAID0 volume, that gets plugged in and a Backup job kicked off.
