Ilmu pengetahuan tentang keamanan komputer yang terkait dengan penyelidikan untuk menentukan sumber serangan jaringan berdasarkan data log bukti, identifikasi, analisis, dan rekonstruksi kejadian adalah Forensik Jaringan yang merupakan cabang dari Forensik Digital. Sedangkan jenis serangan terhadap suatu komputer atau server di dalam jaringan dengan cara menghabiskan sumber daya (resources) yang dimiliki oleh komputer sampai komputer tersebut tidak dapat menjalankan fungsinya dengan benar, sehingga secara tidak langsung mencegah pengguna lain untuk memperoleh akses dari layanan jaringan yang diserang disebut dengan serangan Distributed Denial of Service (DDoS). Riset Forensik Jaringan dilakukan dalam Laboratorium Riset Magister Teknik Informatika Universitas Ahmad Dahlan Yogyakarta. Deteksi serangan dilakukan oleh Winbox RouterOS v3,7 dimana software tersebut menunjukan resources, data penyerang (IP Address), jumlah paket data, dan kapan terjadi serangan. Sedangkan simulasi serangan dilakukan dengan software LOIC untuk mengetahui kinerja sistem pengaman jaringan komputer. Sedangkan sistem pengaman jaringan komputer berupa antisipasi terhadap bentuk serangan DDoS.

Pada sistem saluran transmisi terdapat tegangan gelombang maju dari transmiter ke antena dan tegangan gelombang pantul dari antena ke transmitter. Nilai tegangan gelombang pantul yang tinggi mengakibatkan kerugian dan kerusakan pada transmitter. Perbandingan gelombang maju dan gelombang pantul disebut Standing Wave Ratio (SWR). Semakin kecil nilai tegangan gelombang pantul, nilai SWR semakin kecil dan efisien. Penelitian ini bertujuan untuk merancang pengukur SWR Digital yang berfungsi membaca nilai SWR dan pengaman transmiter FM dari kerusakan akibat tingginya nilai SWR. Penelitian dilaksanakan dengan eksperimen laboratorium yang dibagi dalam empat tahap: merancang pengukur SWR Digital dan pengaman transmiter FM, merancang perangkat keras penampil nilai SWR berupa 2 digit 7-segmen dan pengaman transmiter FM menggunakan mikrokontroler AT89S51 beserta perangkat lunaknya, menggabungkan hasil rancangan kedua tahap sebelumnya untuk membentuk pengukur SWR Digital dan pengaman transmiter FM dari nilai SWR yang tinggi, dan tahap terakhir menguji alat ukur menggunakan dummy load dengan nilai SWR 1,1. Hasil penelitian menunjukkan bahwa SWR Digital dan pengaman transmiter FM 88-108 MHz berbasis mikrokontroler AT89S51 yang dirancang dapat menghitung nilai SWR pada sistem transmiter dan menampilkanya pada 2 digit 7-segmen dan dapat digunakan sebagai pengendali pengaman transmiter FM pada rentang frekuensi 88-108 MHz.

Distributed Denial of Service (DDoS) is a type of attack using the volume, intensity, and more costs mitigation to increase in this era. Attackers used many zombie computers to exhaust the resources available to a network, application or service so that authorize users cannot gain access or the network service is down, and it is a great loss for Internet users in computer networks affected by DDoS attacks. In the Network Forensic, a crime that occurs in the system network services can be sued in the court and the attackers will be punished in accordance with law. This research has the goal to develop a new approach to detect DDoS attacks based on network traffic activity were statistically analyzed using Naive Bayes method. Data were taken from the training and testing of network traffic in a core router in Master of Information Technology Research Laboratory University of Ahmad Dahlan Yogyakarta. The new approach in detecting DDoS attacks is expected to be a relation with Intrusion Detection System (IDS) to predict the existence of DDoS attacks.

At this time the website has become one of the modern information media that is growing very quickly. In making a website, not only the design and information are important, but the security aspect of the website itself has a very important role in a website. The need for website security arises from the need to protect data. First, from data loss and corruption. Second, there are irresponsible parties who want to access and change data. Other problems include self-data protection, excessive delays when accessing or using data. The method used in this test will use tools in the form of software and certain methods used to test the security of a website. To analyze website security, the software used is Snort IDS (Intrusion Detection System) and Wireshark. SQL Injection is actually not a new thing in the world of hacking as a web hacking technique, SQL Injection can damage the database of a website. The technique used in SQL Injection is to input basic SQL commands such as create, insert, update, drop, alter, union and select along with other commands.
