(Institute of Electrical and Electronics Engineers Inc., 2018) Coronel Tapia, Bryan Daniel; Cedillo Orellana, Irene Priscila; Campos Argudo, Karina Pamela; Camacho Cajamarca, Jessica Paola; Bermeo Arpi, Alexandra Elizabeth
Nowadays, with the demand of web applications there is also an increase in the number of problems and crimes that demand an investigation that requires digital forensics techniques in order to manage web evidence. Although there are several studies that address cyber forensics, they are mainly oriented to manage evidence at server side, as far as we know, no systematic literature reviews have been reported on how cyber forensics is addressed at clients’ side; considering the internationals standards. Thus, this paper presents a literature review about how cyber forensics is addressed at clients’ side related to techniques of identification, collection, analysis, preservation and report of digital evidence. Also, a review of how standards are being used in cyber forensics focused on the client side. The aim of this study is to provide a background of relevant activities that are considered by investigators to handle potentially digital evidence from web environments, considering what internationals standards are solving for this purpose. Thus, a total of 37 studies have been selected and analyzed in this study. Moreover, this study provides important insights about the need to create methodologies aligned with formal standards that support the management of the evidence in an appropriate way.

(TICEC 2018, 2018) Camacho Cajamarca, Jessica Paola; Campos Argudo, Karina Pamela; Cedillo Orellana, Irene Priscila; Coronel Tapia, Bryan Daniel; Bermeo Arpi, Alexandra Elizabeth
Nowadays, mobile devices have evolved vertiginously due to their massive adoption by users, who have several devices with different purposes. These devices contain greater capacity/functionality to manage information, with the embedded characteristics they become an important digital evidence container. In recent years, considerable research has been conducted on various types of digital electronic evidence, acquisition schemes and methods of extracting evidence from mobile devices. In this paper, a systematic mapping of the Forensics Analysis on Mobile Device is presented; this research has been conducted following the guidelines of Kitchenham’s methodology. The aim of this study is to provide a background of relevant activities that are considered by investigators to handle with potentially useful digital evidence from mobile devices. A total of 36 primary studies were selected and categorized to extract information regarding the aforementioned classification. The results presented in this contribution provide a detailed study about current analysis in research forensics field by the use of mobile devices.
Metodología para la recolección de evidencia forense generada durante la utilización de aplicaciones desplegadas en entornos web
(2018) Coronel Tapia, Bryan Daniel; Campus Argudo, Karina Pamela; Cedillo Orellana, Irene Priscila
Nowadays, with the increasing on the use of web applications, the rate of problems and crimes through them has also increased. Therefore, that is the reason for the need of a guide that includes digital forensic techniques manage digital evidence from web environments. The main problem, when users are interacting with web applications, is to know exactly where the information is located, or if is possible to access it because of the geographic jurisdiction; consequently, a viable alternative to perform an adequate computer expertise is to carry out the investigation on the computer (client's side). However, while there are methodologies and case studies that provide guidance and good practices, the majority are focused on specific web applications; that is, they cannot be generalized to cover every possible situation. This investigation presents a literature review of trends and practices in this area of study and proposes a methodology that will enable forensic investigators to conduct an investigation throughout the end of it. For the development of the methodology, in addition to considering guidelines and good practices from experts, emphasis has also been placed on recommendations provided by international standards, also a tool has been implemented to reduce the collection times of the main artefacts coming from interactions with web environments, guaranteeing the integrity of the data collected. At the end, the proposals of this study are evaluated by means of a test of concepts.
