development life cycle to ensure software quality based on meeting the criteria for high integrity safety systems. The GTST-MLD- based software development life cycle framework allows one to (1) show how a local change affects other phases of development; (2) GTST-MLD hierarchically represent software development life cycle so as to identify missing and incomplete requirements; (3) it is easy to automate on computers‚ to expand and update. 1.0 Introduction Safety-critical systems are becoming increasingly

Lab #2 – Assessment Worksheet Applying Encryption and Hashing Algorithms for Secure Communications Overview In this lab‚ you applied common cryptographic techniques to ensure confidentiality‚ integrity‚ and authentication. You created an MD5sum and SHA1 hash on a simple text file on a Linux virtual machine and compared the hash values of the original files with those generated after the file had been modified. Next‚ you used GnuPG to generate an encryption key pair and encrypted a message

brain. Top-down processing is the information processing guided by higher-level mental processes‚ as when we construct perceptions drawing on our experience and expectations. Top down processing is the mind interpreting what our senses detect. Without top-down processing‚ one would be able to see someone’s face‚ but not recall that person’s name or remember him or her. This processing is akin to perception‚ which is the process of organizing and interpreting sensory information. Top-down processing

1. What are the five steps of a hacking attack? Reconnaissance ‚ Scanning‚ Gaining Access‚ Maintaining Access ‚ Covering Tracks 2. During the reconnaissance step of the attack‚ describe what task Zenmap GUI performs to do passive OS fingerprinting. Nmap uses the –O option to perform OS fingerprinting. The process monitors and captures network traffic. The traffic is then analyzed for patterns that would suggest which operating systems are in use. 3. What step in the hacking attack process

Part I: Pre-Lab Diffusion/Osmosis Pre-Lab Introduction: Dialysis tubing allows molecules to diffuse through microscopic pores in the tubing. Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences.
