The Impact

Consumers demand fast, high capacity, upgradeable memory cards for portable electronic devices, with secure digital (SD) and microSD the most popular. Despite this demand, secure erasure of data is still not a composite part of disposure practices. To investigate the extent of this problem, second-hand memory cards were procured from the Australian eBay site between 2011 and 2015. Digital forensic tools were used to acquire and analyze each memory card to determine the type and quantity of remnant data. This paper presents the results of the 2014 and 2015 studies and compares these findings to the 2011–2013 research studies. The longitudinal comparison indicates resold memory cards are disposed insecurely, with personal, confidential and business data undeleted or easily recoverable. The impact of such discoveries, where information is placed in the public domain, has the potential to cause embarrassment and financial loss to individuals, business, and government organizations.

Rapid development of cyberspace has created a healthy competition in the creation of computer systems and other devices. The impact of these developments is that cyber threats had caused hectic in digital security area and its reliability to be the trusted system in the industry. Therefore, in order resolve the problem, many countries began developing their own procedures for investigating cyber-related cases based on their own law and regulations and it when the term of digital forensic take place. Researchers began to provide the best definition of each potential element that said as can be a structure in the digital forensic. On other part, the preparations of designing the investigation procedures were based on various designs. In this research, modified investigative procedures are centered on the Malaysian Chief Government Security Office (MCGSO) as a central authority providing advisory services in the field of physical security, document security, personnel security and ICT security. The comparison between approaches had been made where it cover two (2) approaches namely framework and business model. Based on the survey that been made within the organization, selection of design and framework for digital forensic for this organization is based on the business model in general and the Digital Forensic Business Model in particular and it will link together with the general elements and components of digital forensic.

Abstract Standardization offers consistencies for interoperability between jurisdictions and organizational entities. In some instances, accreditation and certification services are available to assure the reputational transfer of conformance and the compliance with best practice requirements. The impact of these benefits is a more predictable environment in which to deliver sensitive and high-risk services, leading to the reduction in failures and the enhancement of inter-party trust. In this article, the case of international standardization for digital forensic and related services is articulated as an example of structured planning for robust processes and practices that have user trust. Political and economic expediency has always reduced the implementation of standardization to functional attributes and short-term returns. The advocacy is for the long-term investment in standardization and the creation of trusted practices for predictable and robust scientific procedures in the transfer of operational knowledge and the preservation of digital evidences.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.
