Abstract

Attacks on networks today are very common, with more and more ways to access data and the development of technology used, they will certainly cause an increase in network security threats. Evaluation of information security management using the information security index (KAMI) conducted on the network at UIN Sunan Kalijaga Yogyakarta obtained an index result of 407, so it is not optimal. This is what underlies the need to implement Open Source SIEM (OSSIM) into the KAMI index. This research was conducted as an optimization to support the information security process so that it can work according to the KAMI index standards. The research methods used include literature study, conducting KAMI Index Pre-Assessment, implementing OSSIM infrastructure, monitoring information security index using OSSIM technology and conducting KAMI Index Post-Assessment, this final stage analyzes the results of monitoring to make comparisons of network conditions before and after implementation of OSSIM on the network. Comparative scores from the results of research related to the KAMI Index show an increase in the score of 25, after applying OSSIM from before without applying OSSIM, the value of 407 becomes 432. The increase in the KAMI index helps raise the value of governance aspects, asset management and technology, but the level of information security eligibility is still at the level of I+ to II+ so the information security on the network is not feasible and needs improvement. where the results match the actual data so that it can be used to help improve the UIN Sunan Kalijaga network based on the Information Security Index. In connection with the information security index (US) the use of OSSIM technology has been proven to increase the value of the Information Security index (US) of Sunan Kalijaga Yogyakarta UIN Network in various aspects, while this increase is due to OSSIM's ability to analyze weaknesses and changes in the configuration of information assets in the UIN Sunan Kalijaga Network Yogyakarta.
