In March, ransomware hit the court system in rural Jackson County Georgia, between Atlanta and Athens. Jackson County paid attackers $400,000. And throughout June, three Florida municipalities—Key Biscayne, Lake City, and Riviera Beach—were hit with ransomware. Lake City paid 42 bitcoin (almost $500,000) to attackers, and Riviera Beach paid 65 bitcoin (almost $600,000).

• Segment the network where web-traffic goes to a DMZ (proxied and filtered), two diferent types of FW, utilize the firewall on the servers "iptables -I INPUT 1 -p tcp -m multiport --dport 22,80,443 -m conntrack --ctstate NEW -j ACCEPT" and drop packets from china or Russia using iptables (shell script can help with this process)

  for i in `cat china.txt`; do iptables -A INPUT -s $i -j DROP; done

  python -c "import os; file = open('chinaip.txt', 'r'); for i in file: os.system('iptables -A INPUT -s i -j DROP'); print(f'Entry succeeded: ' $?)

• If web traffic comes through, put it on IPv6 traffic, put the network on a different type of protocol all together (internally)

• If the data is stored on a segmented network, remove SMB/CIFS from the "Zone 0" data. The filesystem should not have a way of encrpting the data at all, the module for encrption should be removed (put this on Linux or Z/OS), even if there is a payload, the AV should catch this because the application or user is not an approved user from an SELinux standpoint.

• Employ SELinux (MIT's file, process, filesystem, domain application used for controlling the type of execution, if it comes from the web, then the data that comes in in a folder should be setup using "setsebool -P use_encryptfs_home_dirs off" and "semanage fcontext -a -t use_encryptfs_home_dirs "/home/<username>(/.*)?" and finally run ls -lZ /home/<username> to disable encryption on the home dirs.
