SQL Server Column Level Encryption Case Study Example | Topics and Well Written Essays - 500 words

SQL Server Column Level Encryption - Case Study ExampleEven though firms castigate 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 adit to sensitive information is a basic preventive approach to the firms 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 qualified access to sensitive information suffer from the possible virus attack that can destroy the data rather than expose it. With this in mind, ABC shew 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 circle 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 in one case 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 pecking order 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.
