Cryptography & Coding - Essay Example There are various factors involved in the security of a variety of software applications, ranging from protected commerce payments, personal communications as well as defending passwords. One fundamental way for safe communications is cryptography. Cryptography is presently the main information and data security technology. However it is significant to note that as cryptography is essential for safe communications, it is not by itself sufficient. This research presents a detailed analysis of the cryptography technology in terms of information and data safety. In this research I will present the comprehensive overview of the main security and privacy aspects those we need to assess during the implementation of any security policy. The technology of cryptography is very old but its utilization in the information technology sector was seen after the emergence of web based crimes. The research will spotlight on the main cryptographic technology, types, algorithms, application areas, main advantages, and some of the main technological scenarios. Introduction Data is the most important element of the firms for the reason that they heavily rely on this data to run and manage their business tasks. Basically, data can be defined â€Å"as the â€Å"group of unrefined facts representing events taking place in organizations or the physical environment prior to they have been structured and managed into a structure that people can identify and utilize and Information refers to data that have been transformed into a structure that is important and functional to human beings† (Laudon & Laudon, 1999, p.7; Norton, 2001, p.4). Without a doubt, both the data and information are believed to be the main assets of almost all the business organizations. In this scenario, it is essential for the business organizations to protect these assets from possible threats. According to (Laudon & Laudon, 1999, p. 502), â€Å"security is a set of rules, actions, and technical measures u sed to stop unlawful access or modification, robbery, and physical damage to the database. Privacy refers to the right of individuals and organizations to forbid or restrict the compilation and utilizations of information about them.† In the past, information privacy was uncomplicated to retain for the reason that information was kept in different locations. Each business had its own acknowledgment files. Each government agency kept detached records. Doctors kept their own patient files. On the other hand, at present, massive databases store this data online. A large amount of this data is private and secret and should be reachable only to approved users (Shelly, Cashman, & Vermaat, 2005, p. 591). In this situation the data security becomes a big challenge which demands implementation of effective methods. Cryptography provides useful techniques for security of data and information. Technology of Cryptography can be described as the science which deals with the processes of al teration of information or data into a scrambled code that can be decoded and sent all through a private or public network (Akdeniz, 1996; Kessler, 2009). Anonymity and Privacy In their research article (Martin, 2006) discuss that both the privacy and anonymity on the web are noteworthy because they are hard to attain. Online privacy concerns are in the news each day currently.

Business continuity and crisis management Essay - 2

Business continuity and crisis management - Essay Example BCM plays an important role in every organization that uses it. One major aim of having a BCM program on any business to is to give it the capacity to have a quick and effective response to global crises such as cyber attacks mostly through data breaches, natural disasters and ensure the business interests of the organization are protected. (Blyth, M. 2009). What this means is that BCM is not only about crisis management, but it also includes disaster and business recovery, incident and emergency management. The ISO 22301, which is a system of business continuity management, places emphasis on a few areas that are crucial in BCM.First, it suggests that there is a great need to have an understanding of the needs of continuity and preparedness. Moreover, there is need to understand why it is necessary to establish a BCM policy and objectives in an organization. It adds that the effectiveness of the entire process relies heavily on this understanding. Secondly, there is need for an orga nization to implement and operate controls that can manage its overall continuity risks. It therefore, suggests that it would be meaningless to have a BCM policy when the organization is not ready to implement it. (Bajgoric, N. (n.d.). Thirdly, the organization should constantly review and monitor the effectiveness of the BCM program to ensure it is working according to its goals. Finally, the regular assessment of BCM will lead to objective measurements that are important in continual improvement.
