Analysis of Effectiveness of Iptables on Web Server from Slowloris Attack

In the application of network technology, a Web Server is needed that can run well, by providing data services that have the function to accept HTTP or HTTPS requests by maintaining the security of the Web Server from various disturbances or attacks. Along with the development of information technology, it can cause types of crime in technology, especially on web servers. One type of crime that can occur is the Slow loris Distribute Denial of Service (DDoS) attack, which type of attack is focused on disrupting service availability. To overcome these types of attacks in a simple and fast way, it can be applied using the firewall installation method with IP tables filtering tools by conducting research on testing and comparative analysis from before and after the implementation of the IP tables method against Slow loris attacks. Finally, this paper discusses about future solution of DDoS attack and recommendation for secure environment, using IP tables configuration is very effective for secure data, because a simple configuration of IP tables can also limit and block IP directly or completely to attackers who can overcome the attack.
