Abstract
Observed several problems in managing the proxy network in the High Performance Computing (HPC) Laboratory at Politeknik Negeri Bengkalis. There is no priority division for users, for example, there is no bandwidth division between lecturers and students, and the main problem is the lack of optimisation of proxy network security. Therefore, the right solution for the HPC Laboratory is to adjust priorities and bandwidth distribution according to user needs and also create a proxy login page to authenticate and user information. The main focus is the implementation of solutions to improve proxy and web server security using the port knocking method and raw firewall security. Implementation of port knocking with various rules including capturing traffic using the ICMP (Internet Control Message Protocol) protocol or pinging that enters the proxy router, then do the same to capture traffic on the Telnet and SSH (Secure shell) ports with the TCP (Transmission Control Protocol) protocol with the purpose of implementing port knocking is to hide active services from attackers and provide an additional layer of verification before providing access to the desired service and as mitigation of DDOS attacks. Tests that will be carried out involve evaluation before and after the application of Port knocking on proxy with Port Scanning testing using NMAP on Kali Linux. The next test on web server security is DVWA (Damn Vulnerable Web Application) using a raw firewall by testing SYN flood and HTTP flood attacks using LOIC. The test results can show a significant decrease in unauthorised access attempts and also get overall network improvement results.
