Abstract

The Certainty Factor method can help overcome this complexity by providing a level of confidence regarding major recommendations. Certainty Factor allows an expert system to measure the level of confidence or uncertainty associated with each knowledge rule or fact used. Each rule contributes to the overall confidence level, and this can provide an idea of the extent to which the system is confident in the recommendations it produces. In complex decision making, various knowledge rules can influence each other. The Certainty Factor method allows the integration of belief values from interrelated rules, providing a holistic picture of the extent to which evidence supports a conclusion. In some cases, knowledge rules may provide contradictory or conflicting information. Certainty Factor can be used to handle information conflicts by assigning a weight or level of confidence to each piece of information, so that the system can produce more accurate recommendations. Certainty Factor provides a mechanism for measuring the level of uncertainty in a decision. This is important when the available information is incomplete or there is uncertainty in the values used in the knowledge rules. By taking into account the level of uncertainty, the system can provide recommendations that are more realistic and appropriate to complex situations. The Certainty Factor method can be applied dynamically, allowing the system to adjust confidence levels over time or with the addition of new information. This is useful when students experience changes in interest or talent, so the system can provide more accurate and relevant recommendations..

Abstract

Computer network systems are designed to share resources together, so that the security of resources on the server must be maintained and the resources used must be optimized. The aim of this research is to analyze the comparative level of optimization of Port knocking and Honeypot using the IPTables method for network security on servers with different CPU and memory resources. The security methods used in this research are Port knocking, Honeypot and IPTables. The data used includes ports that were successfully attacked as well as resource usage before and after IPTables implementation on a server with 2 CPU resources and 1507284KiB memory obtained from previous research. The results of this research show that 80% of ports cannot be attacked while 20% of ports, namely port 22, are designed to be attacked. The server CPU and Memory resource usage graph shows a decrease after implementing IPTables from Denial of Service (DoS) and Brute force testing. On a server with 1 CPU and 1015852KiB of memory resources, CPU usage decreased by 36%, and memory usage decreased by 41%. Meanwhile, on a server with 4 CPU resources and 6036624 KiB of memory, CPU usage decreased by 41%, and memory usage decreased by 46%. This shows increased effectiveness compared to using just the Port knocking and Honeypot methods. It is hoped that this research can be a guide in measuring server optimization in overcoming Denial of Service (DoS) and Brute force attacks
