During the development of a network application, a programmer adds functionally that makes her able to access the running program without 'authentication' so she can capture debugging data. Prior to finalizing the code and delivering the application, the programmer forgets to remove this added functionality. This sort of security weakness is referred to as ‘backdoor’.
What is 'Backdoor' Security Weakness?
Backdoor is described as any type of security attack where authorized and unauthorized users are able to get around normal security measures and attain high-level root access on a software application, computer system, or network. Backdoor is a potential security weakness that negates an appropriate authentication process to access a system or application. As a result, remote access is granted to databases and file servers of an application that remotely issue system command and update malware.

professor bin is attempting to load bags into the trunk of her car and seeks to load as many bags as possible. the bags are of various sizes (and are infinitely flexible, while maintaining the same volume). she plans to use a greedy algorithm to solve this problem. (a) state the greedy algorithm for this problem (b) does this problem have the greedy-choice property? why or why not? (c) does this problem have the optimal substructure property? why or why not? (d) would there be a greedy solution if instead of optimizing the number of boxes, she instead seeks to fill the largest possible fraction of the space in the trunk? why or why not?
a) The greedy algorithm for this problem would be to load the largest bags first, followed by the next largest, and so on until all the bags are loaded.
b) This problem does not have the greedy-choice property because there may be a situation where loading the largest bag first does not result in the optimal solution.
c) This problem has the optimal substructure property because the optimal solution to the problem can be constructed from optimal solutions to subproblems.
d) There would be a greedy solution if she instead seeks to fill the largest possible fraction of the space in the trunk because the largest bag would always be loaded first, followed by the next largest, and so on.
What is greedy algorithm?
A greedy algorithm would be any algorithm which follows the problem-solving heuristic of making the locally optimal choice at every stage. A greedy strategy does not produce an optimal solution in many problems, but a greedy heuristic could indeed yield locally optimal solutions which approximate a global optimal solutions in a reasonable period of time.
