In this post I will share the iptable script in which we will learn How to protect from port scanning and smurf attack in Linux Server.
Features Of Script :(1) When a attacker try to port scan your server, first because of iptable attacker will not get any information which port is open. Second the Attacking IP address will be blacklisted for 24 Hour (You can change it in script) . Third , after that attacker will not able to open access anything for eg. even attacker will not see any website running on server via web browser, not able to ssh,telnet also. Means completely restricted.
(2) Protects from smurf attack
