Abstract

The increase in online-based services makes a security system for server computers increasingly needed. A server computer is a device that must always be available to be accessed anytime and anywhere. Some of the security systems needed for server computers include security for ssh port access for remote server access needs and a security system to protect servers from Denial of Service (DoS) attacks which can make the server down and completely inaccessible. In this study, a security system is proposed for a server computer with the Linux CentOS operating system on a port 22 secure shell(ssh) access system using the port knock method and a security system to prevent Denial of Service (DoS) attacks on server computers using the RST Cookies method. The simulation results from the port 22 Secure Shell (SSH) access experiment for the server computer can work well where port 22 Secure Shell(SSH) will remain closed and cannot be accessed carelessly except by accessing several ports first according to predefined port knocking rules. Likewise, the implementation of a security system with the RST Cookies method works very well to prevent Denial of Service (DoS) attacks and can still keep the server accessible with a good response time of under 1 ms

Abstract

This research aims to produce a geographic information system with spatial data visualization containing the location of East Lombok souvenir shops, shop information and directions that will be presented to visitors or users. The research targets were carried out in several sub-districts in the East Lombok Regency area which have souvenir shops. This is an effort to introduce craft products and food and drinks that are characteristic of the East Lombok Regency area. The data used in this research is by collecting map data of the East Lombok Regency area using Google Map API and Google Map Direction Service, interviews with shop owners, data collection on coordinate points and several other supporting data. The result of this research is that a web-based geographic information system for East Lombok souvenir shops has been built using the Google Maps API which makes it easy for web users to find out the position of East Lombok souvenir shops, where there is shop information and shop position. , items for sale and directions to the desired store.
