Simulasi Dan Perbandingan PSAD, Suricata Untuk Mencegah Scanning Port Oleh Zenmap Pada VPS Ubuntu

Port scanning is an activity or event to search for and view and examine the port on a computer or server. Port scanning is the first step an attacker to seek information Port - Port that is used in a Server System Information. Because knowing that information exists then an attacker can enter the system that are not contained there in Firewall, therefore, a system must include Port Scanning Firewall security. The purpose of this study for the simulation of Suricata and PSAD as security Firewall on VPS (Virtual Private Server) as well as Scanning Zenmap Port. Researchers used the method is grounded research method that is research based on the testing and use of comparative analysis. The results of this study can be concluded that the application Zenmap capable of doing Scanning Port on a VPS with the time the scan is average - average it takes 11:01 seconds, PSAD and Suricata able to detect irregularities that occur within Server as Scaning Port and provide warnings as well as information such as time of the attack, IPAddress attacker , as well as perform Block IPAddress. So as to secure a server from attacks efficiently
