They also routinely deal with investigations relating to fraud, harassment, insider trading and a range of other highly sensitive security and defense issues. Some of the high profile civil or criminal cases handled by this division may result in disciplinary actions and argued in a court of common law. Due to the nature of business and high sensitivity work done by SCORP Forensics, the security of all aspects of its computer facility will be of the utmost importance.
As the facilities security consultant of SCORP Forensics, it is important to set-up safety measures in terms of survivability of system networks and fault tolerance of computer storage systems. The forensic laboratory (or forensic lab) will contain an analysis machine, image acquisition machine and eight docking stations. Only the docking stations are networked together with eight computer laptops assigned to each forensic investigator. The safety measures of the forensic lab will be the discussion of this report based on the forensic equipment and storage requirements.
SCORP Forensics increasingly depends on large-scale networked systems to conduct business, government, and defense forensic testing and investigations. Survivability of these systems is receiving increasing attention, particularly critical infrastructure protection. As part of its survivable systems initiative, it is compulsory to help foster a survivability network system and develop technologies to analyze and design survivability concepts [3, 10, 11]. Survivability analysis helps identify the essential functions which must survive attacks and failure, the effects of attacks and failures, the associated risks, and the architecture changes which could improve network system survivability.
We define survivability as a network system's capability to fulfill its mission (in a timely manner) in the presence of attacks, failures, or accidents. Unlike traditional security measures that require central control and administration, survivability addresses highly distributed, unbounded network environments with no central control or unified security policy. The focus of our survivability concept is on delivery of essential services and preservation of essential assets during attack and compromise, and timely recovery of full services and assets following attack. We define essential services and assets as those system capabilities that are critical to fulfilling mission objectives. Survivability in the presence of attacks depends on three key system capabilities: resistance, recognition, and recovery. Resistance is a system's capability to repel attacks. Recognition is the capability to detect attacks as they occur and to evaluate the extent of damage and compromise. Recovery, a hallmark of survivability, is the capability to maintain essential services and assets during attack, limit the extent of damage, and restore full services following attack. As an emerging discipline, survivability builds on existing disciplines, including security [14], fault tolerance [5] and reliability [1]. In this report, we focus exclusively on attacks, although our trace-based, compositional ...Download file to see next pagesRead More

Mirroring as a Fault Tolerant System

... differentiation because of the need to use more bandwidth (Leider, 2000). Advantages and Disadvantages to Safeguard Information Several advantages for computer users are seen through the use of mirroring. The first base is on the ability to have synchronized copies of work. Other versions of fault tolerant systems are not able to update information in real-time and often lead to different effects with the network that don’t provide all of the needed data in case of loss. The mirroring process can update and synchronize quickly and efficiently with the information that is being used. The second advantage is that there is not the need to stop the process of working if the data area shuts down or lost. For those who need to have easy...

Comparison of the Cold War International System to the Current International System

An example is that of the Korean War (1950-53) which is said to transform the nature of the Cold War, while its initial impact was to solidify the division of the world into political, military, and economic spheres. Take Germany for instance where imperialism was a victim challenged by the historians for the destruction of the German Government along with its supporters used to conduct (Keylor, 2001, p. 44). That indicates economic expansion and territorial acquisition has always been a problem promoted since the First World War. Even in the 1920s, it was fashionable to declare the German empire on the threshold of the ‘Great War’ (Keylor, 2001, p. 44).

A democratic political system is an essential condition for sustained economic progress. Discuss

What is now clear is that democracy is superior when it comes to countries that have a heterogeneous mix of people and cultures since it is imperative that all sections of society be carried along if the process of economic development has to succeed. In case this does not happen, the concerned country faces the risk of social unrest and the inability of the government to carry all the citizens along with the process of economic development.

If we look at some of the competing ideologies of the 20th century. Communism was the dominant ideology of many countries of the eastern bloc. The basic tenet of communism is the absence of private profit and state ownership of the factors of production. This means that all workers...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements. (Stone, 2007)
Policies are created in order to put in place how politicians and government official...

Restricted Earth Fault Protection System

... Restricted Earth Fault Protection System Introduction Restricted earth fault is a part of electrical power engineering that bases its core role in ensuring that the electrical power by isolating some of the faulted parts from the rest of electrical power. The core objective of the restricted earth faulted is mainly for keeping the power system in a stable condition through isolating only the parts that are at fault, while leaving the rest of the network under operation. In order to remove the fault system, it must apply a pessimistic and a very pragmatic approach (Yeshwant G. Paithankar, 2010) Restricted earth fault or differential Earth protection is a restricted earth fault protection. It is termed to be “restricted” because...
