My Alerts : Deteted, Trojan, Shellcode, Policy, TFTP, all rest are block.
Deleted are rules that have been deleted (pretty self explanatory), Trojan was blocking amazon prime video, shellcode blocks centos repos, so blocking nethserver updates, policy blocks nextcloud desktop app, and I am currently fixing a bricked router and need tftp to communicate 
New rules, new policies on implementing them. I like suricata 4 upgrade.
