We have been asked to provide advise on how a company can manage security on their customer information database. The database maintains information on customer sales contacts, orders, and pricing options. Their goal is a database that will be available to their (traveling) sales people via the Internet, to customers for reviewing orders and payment, and within the company for financial reporting, order forecasting, etc. As such, the system contains confidential information and information where integrity is critical. Your task is to identify security threats, and to choose approaches to reduce the risk. You need to explain why the techniques address the threats, and why the threats matter. We need to describe your recommendations to the Chief Information Officer of the company.
Data has been always the concern of companies around the world. Indeed it is considered even as critical asset. For this purpose, it is essential to manage security concerns of customer information database. As such, we discuss in this report recommendations to tackle these security concerns. First of all, we start by discussion the potential threats to the customer data versus their accessibility locally or outside of the company premises. Listed below are some of the threats that are discovered and should be mimicked. • Security Against Data Jeopardy Customer data that includes payments, orders, shipping etc, is needed sometimes even outside the company premise. In fact, employees need this data accessibility to confirm receipts or law inspections measures. However, this kind of data have to be accessible only to the concerned employees and upon the right authentication. Therefore, when it is needed, a virtual private network is needed to be able to authenticate and access it. Furthermore, two factors authentication process has to be established. This way, the only parties that will succeed at reaching this data specifically are the once that are granted access to that particular virtual private network and must succeed at authenticating using there double factors authentication. • Accidental Sharing Sometimes data needs to be shared either via emails, chats etc. Serving this purpose could lead to data being accessible by unauthorized entities. To mimic this, shared data have to be sent with access right granted only to the concerned parties. This way, if data is exposed to an outsider organization by mistake it will not be accessible, because they are not granted the right to. • System Threats Due to system update failure, precisely after a hot fix release this could cause serious database risk. In fact, data thieves are more focused when a new system release is made. Therefore, keeping up with database update is vital. To overcome that, database & system patches have to be tested after every patch. All in all, there are hundreds of database security threats that could penetrate and jeopardize data and data integrity. Updating the database policy regularly and adhering to it.
2(3x - 7) + 4 (3x + 2) = 6 (5x + 9 ) + 3 Give the value of x
For this exercise, we need to follow a few steps before answering the questions. (1) The first step is to calculate the parentheses on both side of the equation. Which gives us: 2 * 3x - 2 * 7 + 4 * 3x + 4 * 2 = 6 * 5x + 6 * 9 + 3 6x - 14 + 12x + 8 = 30x + 54 + 3 (2) Now we calculate the x numbers and the plain numbers together, such as: 6x + 12x - 14 + 8 = 30x + 54 + 3 18x - 6 = 30x + 57 (3) Third step is to put all the x on one side of the = sign, and the other numbers on the other side, and calculate them. 18x - 30x = 57 + 6 - 12x = 63 (4) Now to get the value of x, we divide 63 by -12 x = -63 / 12 = -21 / 4
