You have just been hired as an information security engineer for a large, multi-international corporation. unfortunately, your company has suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets are private and secured. credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. the other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks.requirementswrite a brief description of the case study. it requires two to three pages, based upon the apa style of writing. use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. use a double-spaced, arial font, size 12.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
