The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the information. 8 Forensics - Definitions • Network Forensics [3]: – Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection.[1] Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. -

It includes management and monitoring of increasing at a gradual rate. It has led to increase in online packets from source IP address to destination IP port crimes and attacks in which malicious packets are being sent to number. It takes amount of packets sent in consideration to other hosts. Network Traffic Analysis comes under Network check flow of consistency in network. Network forensics is Forensics which is one of the classifications of Cyber Forensics that deals with capturing, recording, monitoring and analysis defined in [11] as “capturing, monitoring and scrutiny of of network traffic. Keeping this in view, the paper describes the network events in order to determine the cause of security need of network forensics and its aspects. The paper proposes a attacks and other problem incidents”. It can be said that model for network traffic analysis which is useful for detecting Network Forensics is a branch of digital forensics which is malicious packets received from intruders. studied to examine the network traffic so that attacks and malicious activities can be discovered.

Forensic Attribution Challenges During Forensic Examinations of Databases
Forensic Attribution Challenges During Forensic Examinations Of Databases by Werner Karl Hauger Submitted in fulfilment of the requirements for the degree Master of Science (Computer Science) in the Faculty of Engineering, Built Environment and Information Technology University of Pretoria, Pretoria September 2018 Publication data: Werner Karl Hauger. Forensic Attribution Challenges During Forensic Examinations Of Databases. Master's disser- tation, University of Pretoria, Department of Computer Science, Pretoria, South Africa, September 2018. Electronic, hyperlinked versions of this dissertation are available online, as Adobe PDF files, at: https://repository.up.ac.za/ Forensic Attribution Challenges During Forensic Examinations Of Databases by Werner Karl Hauger E-mail: [email protected] Abstract An aspect of database forensics that has not yet received much attention in the aca- demic research community is the attribution of actions performed in a database. When forensic attribution is performed for actions executed in computer systems, it is nec- essary to avoid incorrectly attributing actions to processes or actors. This is because the outcome of forensic attribution may be used to determine civil or criminal liabil- ity. Therefore, correctness is extremely important when attributing actions in computer systems, also when performing forensic attribution in databases. Any circumstances that can compromise the correctness of the attribution results need to be identified and addressed. This dissertation explores possible challenges when performing forensic attribution in databases. What can prevent the correct attribution of actions performed in a database? The first identified challenge is the database trigger, which has not yet been studied in the context of forensic examinations. Therefore, the dissertation investigates the impact of database triggers on forensic examinations by examining two sub questions. -

DB3F & DF-Toolkit
Digital Investigation 29 (2019) S42eS50 Contents lists available at ScienceDirect Digital Investigation journal homepage: www.elsevier.com/locate/diin DFRWS 2019 USA d Proceedings of the Nineteenth Annual DFRWS USA DB3F & DF-Toolkit: The Database Forensic File Format and the Database Forensic Toolkit * James Wagner a, , Alexander Rasin a, Karen Heart a, Rebecca Jacob a, Jonathan Grier b a DePaul University, Chicago, IL, USA b Grier Forensics, USA article info abstract Article history: The majority of sensitive and personal user data is stored in different Database Management Systems (DBMS). For Example, Oracle is frequently used to store corporate data, MySQL serves as the back-end storage for most webstores, and SQLite stores personal data such as SMS messages on a phone or browser bookmarks. Each DBMS manages its own storage (within the operating system), thus databases require their own set of forensic tools. While database carving solutions have been built by multiple research groups, forensic investigators today still lack the tools necessary to analyze DBMS forensic ar- tifacts. The unique nature of database storage and the resulting forensic artifacts require established standards for artifact storage and viewing mechanisms in order for such advanced analysis tools to be developed. In this paper, we present 1) a standard storage format, Database Forensic File Format (DB3F), for database forensic tools output that follows the guidelines established by other (file system) forensic tools, and 2) a view and search toolkit, Database Forensic Toolkit (DF-Toolkit), that enables the analysis of data stored in our database forensic format. Using our prototype implementation, we demonstrate that our toolkit follows the state-of-the-art design used by current forensic tools and offers easy-to-interpret database artifact search capabilities. -

Email: [email protected] Manuscript submitted January 11, 2016; accepted March 12, 2016. doi: 10.17706/jsw.11.7.631-637 Abstract: The most used applications by the majority of user of computer are web browsers. Users performs their many activities such as, browsing on the internet, download files, use social media applications, accessing e-mail accounts via web browser. Many of the crimes committed on digital resources must be analyzed user activities by examining the records of web browsers. Especially regarding crimes involving entered the URL, access times, browser type, time, downloaded files, search words, such information must be included in the reports of the examiners will create one of the data obtained. Web browser stores user records in different ways. Also, according to user operating systems differ in the locations for storing data. In this study, it is shown that how it should be done the analysis of web browsers on the digital resources which are subject to criminal, the data of different browsers on different operating systems, storage types and data types that can be obtained. In addition, it is showed that, the tools and features used to examine the records in the web browser. Key words: URL records, web browser analyses, digital forensic, digital evidence. 1. Introduction Web browsers are the tools for performing different activities on the Internet by users.
