Download file to see previous pages Even though firms try to encrypt data with various methods and keys, it has been noted that these companies are exposed to two major categories of threats (Jayanty, 2011). Chiefly, restricting access to sensitive information is a basic protective approach to the firm’s data. However, considering that cyber-attacks comprise a major threat to business and research firms, it is observed that access restriction is not enough. Consequently, encrypted data and restricted access to sensitive information suffer from the possible virus attack that can destroy the data rather than expose it. With this in mind, ABC Institute of Research and XYZ Inc. are vulnerable to losing data or having their research finding on genetics expose to their rivals. For this reason, column-level encryption using symmetric keys (Aqarwal, 2011).
Under the circumstances defined above, when encrypting data, it is important to note that data can be accessed in two ways. Firstly, sensitive data is stored in forms of memory and anyone can have access to these memory devices. Secondly, sensitive data can be acquired from its storage device for access to another device. As a result, data encryption should ensure that once an unauthorized personnel is able to get to the data, access to that data is not discernable using a simple query. Ordinarily, ABC and XYZ would store their research findings in various columns that comprise of genetic patterns, associations, links, and procedures of deciphering various DNA codes that all need to be encrypted.
Using the SQL Server Symmetric key encryption, the SQL Server allows the encryption hierarchy that needs to be followed to the latter. Forthwith, the hierarchy allows the creation of a master key for the SQL Server which provides the first step of encrypting the database using a password.  ...Download file to see next pagesRead More

...This physics column shall explore on the physical properties of day to day materials that are linked with the movements of their components, either atoms or molecules. In particular, the study shall explore on the type of motion referred as “heat.” In addition, the column shall attempt to establish the factors that regulate transfer of heat from one substance to the other, especially when they are brought into thermal contact. Moreover, the column shall help us understand the relation that exists between heat and mechanical work. For example, is the heat content affected by any physical force? More significantly, is it possible to extract heat from a substance and apply it in a more...

Pivot Column

...Running Head: THE SIMPLEX METHOD – PIVOTS The Simplex Method: What is a pivot column, pivot row and pivot element? In the simplex method, how is a pivot column selected? A pivot row? A pivot element? Give examples of each. The simplex method, or simplex algorithm as it is also known, is an algorithm used for linear programming. Although simplices are not used in the method, it has been suggested that is operates on simplicial cones, hence the name. Pivot operations are a geometrical process that moves from a basic feasible solution to a second adjacent basic feasible solution. If you take a pivot element (non-zero) in a non-basic column, and then multiply the row that the pivot element is in by its reciprocal then you end... up with a...

... in verification from the database. 5) The use of third party software to manage, FileZilla password might be the best way to go. This is because, FileZilla stores its passwords in plain text and they can easily be viewed in the windows platform. The use of software developed specifically for password encryption and management would solve this problem effectively. A tool such as TrueCrypt provides encryption solutions in the windows platform. This container based encryption method, will encrypt the passwords making them more secure. References Litchfield, D. (2003). SQL Server Security. New York: McGraw-Hill Osborne Media. ....

...Server Server Introduction With technological advancements, the issue of network security has become of significant concern. It is essential for companies to secure the network infrastructure from vulnerabilities and shortcomings that may arise. This stems from the fact that unauthorized users may gain access to an organization’s computer network or system. Consequently, this may lead to exposure of the secret information belonging to a company. It is common for hackers to target the computer network of a company; this may have significant negative impacts on the company (Gollmann, 2011). The computer network should also be secured from damages that may result from physical factors and dangers caused by...

...Spinal Column al Affiliation) Portions of the Spinal Column Cervical Spine- This is the uppermost segment of the spinal column. It is composed of seven vertebrae which are numbered from top to bottom as C1 to C7. The first two (C1 and C2) are tailored to provide for neck movement (Wilke, 2006). C1 is found between the skull and the remaining portion of the spine. C2 is distinguished by a bony projection (also known as the odontoid process) which fits in a hole in C1 to facilitate the rotation of the neck. Thoracic spine- This segment has 12 vertebrae (T1 to T12) and is located in the chest section. The ribs are usually attached to the spinal column on the thoracic...
