Using Firewalld Ipsets to Block Hackers on Rocky Linux 8.6
Using FirewallD and IPSets to block hackers or script kids from your system is really important Having an AWS instance running just 22 hours we can show that 222 individual IP addresses have been used top try and exploit the system by potential hackers.
We also show how using AWK we can filter from the journal log very easily to show the IP Addresses that need to be added to a block list.
Additionally you can find my video courses on Pluralsight: http://pluralsight.com/training/Autho... and take time to see my own site http://www.theurbanpenguin.com
