Abstract

Tunnel PPTP, L2TP, SSTP, and IPsec are VPN types that have been widely supported by network protocols to apply to many computer network devices. These four methods are applied alternately on Mikrotik. In each applied method, will be analyzed using Wireshark application, with Quality of Service (QoS) parameters consisting of Packet Loss, Delay, and Throughput. Tests performed on four clients which connected to the access point. Testing is done with two kinds of networks, the first one in which all client access web for download purpose and the second one in which all client access web for streaming video. The security testing result between PPTP tunnels, L2TP, SSTP, and IPSec shows that security level built by IPsec tunnels better than the L2TP, SSTP, and PPTP tunnels. Moreover, based on the results of testing on performance, security and test findings obtained that IPsec VPN tunnel better than tunnel VPN PPTP L2TP and SSTP.Keywords— Layer 2 Tunneling Protocol, Point to Point Tunneling Protocol, Quality of Service (QoS), Secure Socket Tunneling Protocol, Virtual Private Network DOI: 10.5281/zenodo.1444898

Abstract

Security is very important especially to maintain the integrity of data for internet service users. There are many ways to infiltrate computer networks, starting from just experimenting to trying to damage and steal important information on the server. One way to overcome this problem is by the existence of an attack prevention system or commonly referred to as the Intrusion Prevention System (IPS) so that an attack can not directly touch the data or files that others should not know.Honeypot is a system that is deliberately sacrificed in order to be attacked to obtain information from the activities of the attacker and to know the methods used in attacking a system. The results of attacks on the system can be displayed in a monitoring system and can also be displayed through a web service. The results obtained from this study that the creation of a web service -based computer network attack monitoring system uses a honeypot as an IPS successfully implemented. Attacks that enter through TCP ports are 33.96%, UDP 33.96%, and ICMP 32.07%.Keywords— Honeypot, Web Service, Intrusion Prevention System DOI : 10.5281/zenodo.2651714

Abstract

Pemeriksaan harian alat berat dan kendaraan operasional penting untuk mencegah kerusakan tidak terduga, menekan waktu henti dan mendukung keselamatan operasi. Pada PT Bumi Sarana Beton, data pemeriksaan sebelumnya dicatat secara manual sehingga berisiko menimbulkan ketidakkonsistenan penilaian, keterlambatan pelaporan, dan dokumentasi yang terpisah. Penelitian ini mengembangkan sistem berbasis web untuk diagnosis kerusakan dan evaluasi kelayakan operasional menggunakan metode Fuzzy Tsukamoto. Sistem mengolah data pemeriksaan harian yang dikelompokkan ke dalam tiga variabel penilaian, yaitu sistem utama operasional, mobilitas dan struktur, serta safety dan kontrol. Kondisi komponen dikonversi menjadi skor numerik, difuzzifikasi melalui fungsi keanggotaan, dievaluasi menggunakan aturan fuzzy dan nilai alpha-predikat minimum, kemudian didefuzzifikasi dengan rata-rata terbobot untuk menghasilkan nilai kelayakan tegas. Hasil akhir dipetakan ke dalam tiga status operasional, yaitu Tidak Layak, Perlu Perhatian, dan Layak. Sistem juga menerapkan hard safety override pada komponen kritis sehingga kondisi rusak atau hilang dapat mengunci status akhir menjadi Tidak Layak tanpa bergantung pada nilai fuzzy. Implementasi sistem mencakup form P2H, unggah foto bukti, hasil diagnosis, riwayat pemeriksaan, dan laporan. Pengujian white box menunjukkan seluruh 19 skenario internal lulus, sedangkan evaluasi awal confusion matrix terhadap enam data uji menghasilkan akurasi 83,33%. Hasil ini menunjukkan bahwa sistem dapat mendukung keputusan pemeriksaan yang lebih cepat, konsisten, dan dapat ditelusuri, meskipun pengujian lanjutan dengan data yang lebih besar dan seimbang masih diperlukan
