Abstract
Ease and support for cloud-based data storage It has supported an increase in the number of cloud services. The increasing number of uses for cloud services also increases the number of digital-based criminal actions related to the addition of facilities to cloud services. The cloud service feature designed to store data to support the smooth running of business processes can be misused by criminal assistance to store crime data. Accurate digital evidence is one way to prove a digital crime, which can then be used as supporting evidence in the trial. This study discusses the analysis of digital evidence from a cloud service. The analysis process using the NIST 800-86 method is carried out on digital evidence from 5 previously prepared scenarios related to the use of cloud service features that use being misused. Data acquisition techniques use the method of direct acquisition and physical imaging to obtain digital evidence. The experimental results showed that after scenario 1 and scenario 3, information on the file name and directory of the paths downloaded by client 1 and client 2 were obtained with information on the IP address, mac address, user name, password and time stamp. After scenario 2, digital evidence has been obtained that contains information on the name and location of the folder on the cloud server. After scenario 4, information on the name of the file and the shared folder is successfully obtained, equipped with client information that has the right to access the files and folders. After scenario 5, information about the file name and directory of the file path is successfully obtained.

Summary
Layanan cloud computing merupakan kolaborasi pemanfaatan teknologi komputasi dan pengembangan sistem berbasis internet yang menawarkan fasilitas sumber daya tanpa perangkat tambahan, biaya yang lebih terjangkau dan penyimpanan data yang tidak terbatas. Maka diperlukan metode untuk menangani kasus kejahatan cyber, yaitu dengan menggunakan teknik akuisisi data untuk menganalisa dan mengumpulkan bukti-bukti digital dari tindak kejahatan. Berbagai analisis forensik digital untuk menemukan bukti dari suatu aktivitas kriminal berbasis layanan cloud computing pernah dilakukan dalam penelitian sebelumnya, diantaranya: menggunakan metode The Advance Data Acquisition Model (ADAM) [4], metode End to End Digital Investigation (EEDI) [5], National Institute of Standard and Technology (NIST) [6], National Institute of Justice ( NIJ ) [7]. Penelitian ini bertujuan untuk melakukan akuisisi data bukti digital menggunakan metode NIST melalui simulasi dari beberapa skenario yang mencakup fitur cloud yang sering digunakan, serta skenario yang dapat menghilangkan bukti digital. Proses analisa dilakukan untuk menyimpulkan karakteristik bukti digital dari layanan cloud computing yang diteliti
