Explanation of Solution
Project:
- A project is actually a temporary endeavor for creating a unique product, service or result.
- A project is a temporary social system which is constituted by teams to accomplish specific tasks under specified time.
- Project is a set of interrelated tasks which is to be executed over a fixed period of time and within certain cost and within other limitations.
- A project or a program can be treated as an undertaking that involves research or design and is planned for achieving a particular goal.
Main attributes of a project:
The main attributes of a software project include the following.
- A project needs a well-defined objective
- The main objective of project can be defined in terms of scope, schedule and cost...
Explanation of Solution
Difference of project from day to day jobs:
| Project | Day to day job |
| The project activities will be completed only when the project is stopped. | Day to day work will continue on an ongoing basis and is required even after the project finishes... |
Explanation of Solution
Triple constraint:
- In terms of scope, time and cost goals, every project is constrained in different ways. In project management, these limitations are termed as triple constraint.
- Triple constraint is also termed as project management triangle or iron triangle...
Explanation of Solution
Factors affecting a project:
- Deadline:
- Deadline is one of the factors that determine how a project will be handled.
- Missing a deadline will create a bad impression on the team.
- Budget:
- Budget is another factor that determines project’s progress and management.
- The number of days for completing the project and the number of resources will be more if there is high budget.
- Stakeholders:
- Depending on the kind of stakeholders for the project, techniques for managing a project will vary...

This problem tests your understanding of the program stack. Here are some notes to
help you work the problem:
⚫ strcpy(char *dst, char *src) copies the string at address src (including
the terminating '\0' character) to address dst. It does not check the size of
the destination buffer.
• You will need to know the hex values of the following characters:
1234
3. Which line prevents compiler optimization? Circle one: 1234
Suggested solution:
Store strlen(str) in a variable before the if statement.
⚫ Remove the if statement.
Replace index 0 && index < strlen(str)) {
5 }
}
=
str [index] = val;
Character Hex value | Character Hex value Character Hex value

Now consider what happens on a Linux/x86 machine when callfoo calls foo with
the input string "ZYXWVUTSRQPONMLKJIHGFEDCBA".
A. On the left draw the state of the stack just before the execution of the instruction
at address Ox40053a; make sure to show the frames for callfoo and foo and
the exact return address, in Hex at the bottom of the callfoo frame.
Then, on the right, draw the state of the stack just after the instruction got
executed; make sure to show where the string "ZYXWVUTSRQPONMLKJIHGFEDCBA"
is placed and what part, if any, of the above return address has been overwritten.
B. Immediately after the ret instruction at address 0x400543 executes, what is
the value of the program counter register %rip?…

- 123456 A ROP (Return-Oriented Programming) attack can be used to execute arbitrary instructions by chaining together small pieces of code called "gadgets." Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'. Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function. Additionally, you are provided with five useful gadgets and their addresses. Use these gadgets to construct the stack layout.
