The Lab #4 Assessment Questions and Answers 1. What is a PHP Remote File Include (RFI) attack‚ and why are these prevalent in today’s Internet world? RFI stands for Remote File Inclusion that allows the attacker to upload a custom coded/malicious file on a website or server using a script. This vulnerability exploits the poor validation checks in websites and can eventually lead to code execution on server or code execution on website (XSS attack using javascript). RFI is a common vulnerability

Christine Woelfel-Monsivais 10/13/14 Chem 4448.13 Lab 4: Gaussian Calculations Introduction The purpose of the lab was to gain a better understanding of the Gaussian calculations and see how the obtained calculations can be used to explore the chemistry of the atoms. In this lab several molecules were created and given specific bond lengths before running a Gaussian test for optimization and frequency. Through this test the vibrational frequency‚ force constant‚ reduced mass and point group were

* Cube In geometry‚ a cube is a three-dimensional solid object bounded by six square faces‚ facets or sides‚ with three meeting at each vertex. As the volume of a cube is the third power of its sides ‚ third powers are called cubes‚ by analogy with squares and second powers. A cube has the largest volume among cuboids (rectangular boxes) with a given surface area. Also‚ a cube has the largest volume among cuboids with the same total linear size (length+width+height). * Parts:
