Abstract

The rapid growth of SMK IDN since its establishment in 2016 has necessitated the addition of several branches. With the increasing number of branches, SMK IDN's administrative activities need to be centralized at SMK IDN Jonggol (Central), where the school leases and utilizes MPLS services to support interconnections between branches and the central office. However, there are considerations regarding using MPLS services as the number of SMK IDN branches continues to grow. Concerns from the SMK IDN IT team include issues related to the inflexibility of MPLS links, which can only be specifically used for interconnecting branches or private links that cannot simultaneously accommodate the internet needs of branches. In this situation, the SMK IDN IT team seeks an efficient solution that provides flexibility in interconnections from branches to the central office, with capabilities and stability equal to or better than before. In response to the challenges faced by SMK IDN, we propose the Load Balancing SDWAN solution, where SMK IDN only needs to use internet services available at the central office and branches. The Load Balancing SDWAN solution offers flexibility in terms of cost efficiency and link usage because links can simultaneously fulfill internet and interconnection needs for branches. In its implementation, the Load-balancing SDWAN method effectively addresses the challenges encountered by SMK IDN. Test results show that after implementing the Load Balancing SDWAN method, there is a significant improvement in internet access stability for users, with the ability to failover if there are issues with one internet link, as well as maintaining secure and private connections between the central office and branches. Another benefit of implementing the Load Balancing SDWAN method is budget efficiency, as SMK IDN can provide dedicated internet services per month at a 63% lower cost compared to renting MPLS links previously used

Abstract

In the industrial era 4.0, which is marked by the rapid progress of computer networks and the internet, network security at Layer 2 is part of the Data Link Layer in the OSI model, which is very important considering the increasing number of cyber threats. This research aims to compare the effectiveness of various security algorithms applied to Layer 2 switches, namely MAC Address Filtering with Port Security, VLAN Hopping Mitigation, and DHCP Snooping. Some of these methods have the function or purpose of creating MAC address filtering, port limitations, VLAN protection, ARP, etc. The device used to conduct this research is a Cisco Switch. This research uses an experimental approach by implementing each method in different network scenarios and comparing it with external data, measuring effectiveness based on attack detection and prevention, as well as its impact on network performance, then combining several of these methods into one scope. The results show that each method has its own advantages and disadvantages, which function to block various types of attacks such as Flooding, Snooping, and Rogue DHCP. It is highly recommended to combine all security methods into one integrated system.

Abstract

IDN Bogor Vocational High School, which was established in 2016, is known as one of the many schools that are involved in the academic, religious and IT-focused world, as its vision is "Wonder of IT Smart of Praying". Given the large number of IT activities both in terms of learning and administratively office data collection (Administration), of course the application of a Firewall on the network is one of the crucial things needed to facilitate the security and authenticity of data from teachers and students. The purpose of preparing this KKP report is none other than to help optimize Firewall configurations, both on Firewall devices and PCs/Laptops along with counseling strategies as preventive measures to avoid physical/social engineering hacking at SMK IDN Bogor. As we all know, cybersecurity issues cannot be taken lightly. Therefore, for the sake of the continuity and smooth running of school education activities, Optimization/Standardization of all segments or parts that use the network within SMK IDN Bogor is required.
