Abstract :
The impact of the global pandemic as a result of the 2019 Corona Virus (Covid-19) caused the Indonesian government to implement Large-Scale Social Restrictions (PSBB) which resulted in decreased activities in various sectors, one of which was the education sector. Implementation of computer-based exams or so-called Computer Based Test (CBT). CBT is implemented in a local network (LAN) environment only, due to server data security factors. Because for clients who will access the server using the IP address and server port directly. A DMZ is a physical or logical subnetwork that protects the inner network (LAN) from untrusted outsiders. The purpose of the DMZ is to add an additional layer of security to a local area network (LAN) The analysis of the application of the DMZ on the CBT server uses the Network Development Life Cycle (NDLC) research methodology. Of the 6 stages, only 3 stages are used, namely Analysis, Design, and Simulation Prototyping. Then the trial will be continued with the experiment client (both from the local network and from the internet) to access the CBT server before and after the DMZ configuration and comparing the results. It is known that before the DMZ configuration was carried out, the server IP and port could only be accessed via a local network (LAN) and could not be accessed via the internet. After configuring the DMZ and testing again. The results and conclusions of this study are that the DMZ is able to hide the IP Address and Port of the CBT server. Before a client from outside the LAN accesses the server, the DMZ system first filters the IP and port the client will access. Clients that access using Dst.Address and Dst.Port correctly will be diverted to the correct CBT server IP and port
