To protect digital evidence during Computer Forensics, the measure of protection digital evidence was analyzed, and a project of protection digital evidence (Digital Evidence Protection System, called DEPS) was designed. In this paper, the framework and element of DEPS was introduced, and the mechanism of multi-digital-signature and digital time-stamp of DEPS was described.

The World

This chapter introduces computer and network forensics. The world of forensics is well understood in the non-digital world, whereas this is a nascent field in the digital cyberworld. Digital evidence is being increasingly used in the legal system such as e-mails, disk drives containing damaging evidence, and so on. Computer forensics deals with preserving and collecting digital evidence on a single machine while network forensics deals with the same operations in a connected digital world. Several related issues and available tools are discussed in this chapter.

Network Forensic

The common cases that often occur on a computer network is a weak point of computer security on computer networks. Network Forensic is a process of analyzing activity, recording, or even to identify the network to find digital evidence from a computer crime. Since the existence of the Internet as a global communication tool, it is a crime that often occurs gap. Internet containing the network forensics and lawful interception are important tasks for many organizations including small medium business, enterprises, banking and finance industry. This archiving and restoration of internet data can be used for legal evidence in case of disagreement. Government and intelligence agencies use technology to protect and defend national security. In general, computer forensics is simply the application of computer investigation and analysis techniques to determine the legal evidence that may be. There are several ways to find a crime on a computer network. The use of several applications supported are to improve the success of network forensic processes in the common cases.

Kejahatan konvensial yang terekam kamera CCTV (Closed Circuit Televison) semakin banyak ditemukan di masyarakat, setiap pelaku kejahatan yang terbukti melakukan tindak pidana tertentu akan dihukum sesuai dengan peraturan perundang-undangan. Kamera CCTV memiliki peran penting dalam keamanan, banyak diantaranya hasil tangkapan rekaman kamera CCTV dijadikan sebagai alat bukti digital. Tantangannya adalah bagaimana teknik yang diperlukan untuk penanganan khusus investigasi digital forensik dalam mencari bukti ditgital rekaman kamera CCTV menggunakan metode live forensik, yaitu ketika barang bukti dalam keadan aktif berdasarkan pedoman SNI 27037:2014 sesuai acuan kerangka kerja Common Phases of Computer Forensics Investigation Models untuk di implementasikan ke dalam dokumen Chain of Custody. Hasil penelitian ini berupa hasil analisis video rekaman kamera CCTV tentang karakteristik bukti digital dan informasi metadata yang digunakan untuk memberikan penjelasan komprehensif secara terstruktur serta acuan pengelolaan informasi data yang didapat dari hasil investigasi digital forensik yang dapat dipertanggungjawabkan dalam persidangan.   Kata kunci: Bukti Digital, Live Forensik, Metadata, Kamera CCTV, Chain of Custody.   Abstract Conventional crimes that are recorded on CCTV (Closed Circuit Television) cameras are increasingly being found in society, every crime that commits certain crimes will be in accordance with statutory regulations. CCTV cameras have an important role in security, many of which are recorded by CCTV cameras used as digital evidence. The challenge is how the techniques required for special handling, digital forensics in searching for digital evidence of CCTV camera footage using the live forensic method, namely when the evidence is in an active state based on the latest SNI 27037: 2014 according to the framework reference Common Phases of Computer Forensics Investigation Models for in implement it into the Chain of Custody document. These results of this research are in the form of analysis of CCTV camera video recordings about the characteristics of digital evidence and metadata information used to provide a structured comprehensive explanation and reference data management information obtained from the results of digital forensic investigations that can be accounted for in court.  Keywords: Digital Evidence, Live Forensic, Metadata, CCTV Camera, Chain of Custady.

This chapter includes the evolution of cyber forensics from the 1980s to the current era. It was the era when computer forensics came into existence after a personal computer became a viable option for consumers. The formation of digital forensics is also discussed here. This chapter also includes the formation of cyber forensic investigation agencies. Cyber forensic life cycle and related phases are discussed in detail. Role of international organizations on computer evidence is discussed with the emphasize on Digital Forensic Research Workshop (DFRWS), Scientific Working Group on Digital Evidence (SWDGE), chief police officers' involvement. Authenticity-, accuracy-, and completeness-related pieces of evidence are also discussed. The most important thing that is discussed here is the cyber forensics data.

Digital Forensic

Digital Forensics is a technique used to search for evidence of events that have occurred. This quest aims to reveal the hidden truth. The existence of digital forensic activities due to the occurrence of crimes both in the field of computers or other. Legal treatment in digital forensic field makes this area of science a compulsory device to dismantle crimes involving the computer world. In general, the cyber crime leaves a digital footprint, so it is necessary for a computer forensics expert to secure digital evidence. Computer forensics necessarily requires a standard operational procedure in taking digital evidence so as not to be contaminated or modified when the data is analyzed. The application of digital forensic is beneficial to the legal process going well and correctly.

Instrumental Role

With the advent of computers, there came computer-related crimes; hence, there comes the need for cybercrime judicial proceedings. And for any trial, evidence plays an instrumental role in bringing the victim to justice. So, there is a need for digital evidence. Digital crime evidence forms a core for the field of computer forensics. Breaking down the term digital crime evidence to be understood in simple words, it is the collection of data and information that plays a crucial role in digital crime investigation and that is usually stored and transmitted in electronic formats. Digital evidence is defined as any data stored or transmitted using a computer that supports or refute a theory of how an offense occurred or that address critical elements of the offense such as intent or alibi. This data is commonly a combination of text, audio, images, and videos. This evidence is generally invisible, fragile, time-sensitive, and integrity will be lost if they are mishandled.
