Question
1- Explain how inheritance works?
2- What is prototyping and what does it accomplish (include the resource allocation and planning implications in your answer)?
3- At what point in the process should formal techniques be employed (specifically, you must provide a justification for why here and not somewhere else)?
4- Business Process Models (BPM) involve trade-offs. Justify for me why tradeoffs are required and tell me what the BPM process adds to the finished product (e.g., the specification)?
5-There are two categories of analysis techniques, functional and object oriented. Tell me the difference between the two and then explain how both support the specification process (e.g., what do they produce that is useful to understanding the problem)?
6- In simple terms, what is the purpose of the stakeholder in the SQUARE method. Why is the stakeholder role critical to the security of the final product?
7- SQUARE essentially involves two stages. Stage 1-4 entails one type of activity and stage 5-9 entails another. What is the purpose of these two types of activities? What would happen if either were not done?
8- Steps seven and eight In the SQUARE method involves the categorization and prioritization of activities. Why is this important for security? What would happen if activities were not categorized and prioritized?
9- Step One of SQUARE involves obtaining agreement on definitions. Why is this a critical part of the security process? What would happen if this step was skipped?
10- SQUARE for acquisition is a special application of the SQUARE process. Tell me why it is particularly critical to get a good set of security and functional requirements even if the product is purchased off the shelf rather than developed?

Inherit Definition - Derive quality and characteristics from parents or ancestors. Like you inherit features of your parents.
Example: "She had inherited the beauty of her mother"
Inheritance in Object Oriented Programming can be described as a process of creating new classes from existing classes.
New classes inherit some of the properties and behavior of the existing classes. An existing class that is "parent" of a new class is called a base class. New class that inherits properties of the base class is called a derived class.
Inheritance is a technique of code reuse. It also provides possibility to extend existing classes by creating derived classes.
Inheritance Syntax :
The basic syntax of inheritance is:
Access specifier can be public, protected and private. The default access specifier is private.Access specifiers affect accessibility of data members of base class from the derived class. In addition, it determines the accessibility of data members of base class outside the derived class.
