Home Advances in Cyber Security Conference paper Analysis of File Carving Approaches: A Literature Review Nor Ika Shahirah Ramli, Syifak Izhar Hisham & Gran Badshah Conference paper First Online: 01 January 2022 1262 Accesses 2 Citations Part of the Communications in Computer and Information Science book series (CCIS,volume 1487) Abstract Digital forensics is a crucial process of identifying, conserving, retrieving, evaluating, and documenting digital evidence obtained on computers and other electronic devices. Data restoration and analysis on file systems is one of digital forensic science’s most fundamental practices. There is a lot of research being done in developing file carving approaches and different researches focused on different aspects. With the increasing numbers of literature that are covering this research area, there is a need to review this literature for further reference. A review is carried out reviewing different works of literature covering various aspects of carving approaches from multiple digital data sources including IEEE Xplore, Google Scholar, Web of Science, etc. This analysis is done to consider several perspectives which are the current research direction of the file carving approach, the classification for the file carving approaches, and also the challenges are to be highlighted. Based on the analysis, we are able to state the current state of the art of file carving. We classify the carving approach into five classifications which are general carving, carving by specific file type, carving by structure, carving by the file system, and carving by fragmentation. We are also able to highlight several of the challenges for file carving mentioned in the past research. This study will serve as a reference for scientists to evaluate different strategies and obstacles for carving so that they may choose the suitable carving approaches for their study and also future developments

S.A.Q RPG (Sejarah Awesome Quest Role-Playing Game): History Subject Educational Game for Young Learner

History subject is one of the subjects required to pass the Sijil Pelajaran Malaysia (SPM) examination set by the Ministry of Education Malaysia (MOE). With rapid technology growth, more educational uses and dedicated virtual worlds focused on education will begin to evolve, encouraging new and more advanced learning scenarios, allowing the development of analytical skills and greater reflection. History is often associated as a dry and boring subject due to the high factual content and horizontal storytelling in the classroom resulting in the subject of history as one of the subjects that are less preferred by students. To overcome this situation, a game-based learning is a good approach in line with the development of technology today. S.A.Q RPG (Sejarah Awesome Quest Role-Playing Game) is a game-based learning medium which focus in using game to familiarize and increase students understanding of history concept. This game is built by using ADDIE (Analysis, Design, Development, Implementation and Evaluation) model and the development is done by using Unity software. A survey will be done for 40 students in the evaluation stage to asses effectiveness of the proposed game. It is believed that historical educational games can be used as an opportunity to facilitate the study of history in an enjoyable atmosphere

Performance Comparison Between AODV and DSR In Mobile Ad-Hoc Network (MANET)

Wireless communication technology has advanced rapidly, thanks to the proliferation of wireless devices and services. The spectrum depletion issue was discovered due to the growing number of users and to the fixed spectrum assignment strategies. A mobile ad hoc network (MANET) is a network that doesn’t require a central server, specialized gear, or fixed routers to function. As it operates in a distributed peer- to-peer style, each system acts as an individual router and produces individual data where MANET may be used as a stand-alone network or as part of a cellular network that connects to the internet. There are different types of a routing protocol can be applied in MANET, each with its capabilities, advantages, and disadvantage. There is a need to investigate the performance of routing protocol for better network planning. The Ad Hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) are two MANET routing protocols investigated in this paper. Four different performance metrics are used to measure these protocols: throughput, path discovery time, traffic received and sent delay, and media access delay. To investigate the behavior of these protocols in the Manet context, a Manet simulation is run using OPNET Modeler Student Edition. According to the data, AODV outperforms other protocols in terms of throughput, amount of traffic received, and transmit performance, whereas DSR has the longest delay. Even when run in the same environment with the same number of nodes, different protocols produce different readings and behaviors. This proves the theory that AODV performs better in terms of performance, delay, and packet transfer ratio

STUDY OF EMPLOYEE SATISFACTION AGAINST DIFFERENT ASPECTS : A CASE STUDY OF MANUFACTURING INDUSTRY (DRB HICOM SDN BHD)

Job Satisfaction refers to how employees view their work, as well as the psychological attitudes that people have towards their jobs. Given the strong association between the impact of job performance , it is important to better identify and acknowledge the factors which affect the overall employee job satisfaction which correlated to the employee performance. A study to analyze the factors affecting employee satisfaction that affect employee performance is necessary. The objective of this research is to investigate the association between job satisfaction and different factors affecting employee performance among employees in the DRB-Hicom Sdn Bhd manufacturing industry. This research uses a quantititative method where a questionnaire survey is used to assess job satisfaction based on variables which are work, salary, management communication, and demographic profilling and how they can affect joc satisfaction. The demographic profilling contribute to minimally to none to the employee satisfaction whereas work, salary, and management greatly affect the entire employee satisfaction rate according to the high mean value of the factors. Correlation study shows that there is a positively high level of correlation strength between work, salary, and management communication against the employee performance which supports the hypothesis made for this research

Survey of File Carving Techniques

File carving is a method that enables researchers to collect data from unallocated memory space. File carving is a technique used to retrieve data other than data recovery technique and data restoration technique. In general, carving is used to retrieve data with the absence of metadata that point to the content. There are various styles of file carving techniques used for types of files, including PDF, JPEG, XML and etc. [5]. This paper focuses mainly on the different types of carving techniques commonly used based on particular circumstances. The key contribution of this paper is the study and analysis of current existing file carving techniques for file carving in order to define their functionality. These techniques are also classified according to the carving method styles used and the fragmentation issues as well as the type of a file system since these techniques rely on the content and the file structure of the particular file to be carved. This paper is divided into two sections, the first section is the traditional carving approach and the second section is the advanced carving approach. This paper will be a guide for researchers searching for carving techniques in order to choose the appropriate carving algorithm and to continue improving it in the future
