Software Security is perhaps one of the most important non-functional requirements these days. In the traditional SDLC models, Security testing takes place at the end (after the functional requirements are fulfilled). However with modern application security testing tools, we can easily integrate security testing throughout the SDLC. We can do this by conducting security assessments during all phases of software development.

Improving Software security throughout the SDLC helps in creating more reliable software. Do you agree with this statement or not? Justify your answer with well-defined reasoning

Imagine that you have invented a formula for projecting the next day's temperature based on temperature and wind data from surrounding regions. You have implemented this calculation in a program on your laptop, but a colleague needs to make it work on another computing device that may have a very different architecture. Which of the following representations is the least portable representation?

1) 

Java source code for a program that implements the algorithm

2) 

Java byte code for a program that implements the algorithm

3) 

C++ source code for a program that implements the algorithm

4) 

Machine code for a program that implements the algorithm

XYZ orders 5000 custom made parts from ABC for one of its products. When the order is originally made ABC indicates it will charge $75 per part. This cost is based in part on the cost of materials. After the agreement is completed, but before production of the part begins, ABC engineer Christine Carsten determines that a much less expensive metal alloy can be used while only slightly compromising the integrity of the part. Using the less expensive alloy would cut ABC's costs by $18 a part.

Christine brings this to the attention of ABC's Vernon Waller, who authorized the sales agreement with XYZ. Vernon asks, "How would anyone know the difference?" Christine replies, "Probably no one would unless they were looking for a difference and did a fair amount of testing. In most cases the performance will be virtually the same -- although some parts might not last quite as long." Vernon says, "Great, Christine, you've just made a bundle for ABC." Puzzled, Christine replies, "But shouldn't you tell XYZ about the change?" "Why?" Vernon asks, "The basic idea is to satisfy the customer with good quality parts, and you've just said we will. So what's the problem?"

The problem, Christine thinks to herself, is that the customer isn't getting what was promised. Further, even if XYZ would be satisfied with the different part, shouldn't it be given the opportunity to decide if it finds the change acceptable -- and to benefit from lowered cost?

Should Christine share her further thoughts with Vernon, or should she simply drop the matter?
