Abstract

Spanning Tree Protocol (STP) is used in switch manageable devices that apply more than one path to the connection between switches. The use of these lines is intended so that data transfer speeds between switches reach speeds above 100 mbps. This study aims to assist engineer staff in improving a network security spanning tree protocol (STP). And its benefits are to improve the Spanning Tree Protocol (STP) network security system by using Spanning Tree Protocol mitigation techniques and VLAN trunking. This research begins with literature study, analysis of data monitoring and data retrieval before STP is attacked and after being attacked using the Wireshark application. Then the PC to PC file transfer test was carried out with the speed out version 5.0 application. The results of this test contain data before STP is attacked, after STP is attacked and anticipatory data. Then, a simple linear regression analysis was carried out with the result that there was no significant relationship between time and size in the DoS attack, where 48.6% of the time variable was influenced by the size variable, the remaining 51.4% by other variables while the root attack was 43.8% variable time is influenced by the size variable, the remaining 56.2% by other variables. The correlation between Karl Pearson DoS and root, there is a significant relationship between time and size, with the DoS correlation coefficient (-0.697) while root (- 0.662), and the paired sample t-test (paired sample t-test) can be concluded that there is a difference before STP attacked and after STP was attacked. It can be seen from the comparison of the mean before the STP was attacked and after the STP was attacked there was a significant decrease in the average. After the conclusion of the paired sample t-test, the BPDU guard and root guard mitigation was carried out, but they could still be attacked so that the next step was needed, namely VLAN trunking. In addition, there is also a website application for displaying graphical data and tables
