- b) Demonstrate your understanding of the methods applied to protect your system against this type of attack in the operating system. you may elaborate in details the methods which you will select and demonstrate the efficiency of such methods.What is your level of interest in furthering your knowledge of the system's security?How do you characterize the threat from the point of view of the underlying network/operating system architecture? I was wondering if you could provide any examples of hazards that people face in the actual world.
- What is a software hazard analysis, and how is it performed in the context of safety-critical software?How should the risk be defined from the point of view of the network and operating system? Also, what are some examples of hazards that occur in the actual world?Risk to the operating system? Anything else?
- How do safety standards like DO-178C for avionics or IEC 61508 for industrial systems influence software safety practices?Operating System Exposures and ControlsListed here are five scenarios. For each scenario, discussthe potential consequences and give a preventiontechnique.a. The systems operator opened a bag of burned microwave popcorn directly under a smoke detector in thecomputing room where two mainframes, three highspeed printers, and approximately 40 tapes arehoused. The extremely sensitive smoke detector triggered the sprinkler system. Three minutes passed before the sprinklers could be turned off.b. A system programmer intentionally placed an errorinto a program that causes the operating system tofail and dump certain confidential information todisks and printers.c. Jane’s employer told her she would be laid off in 3 weeks.After 2 weeks, Jane realized that finding another secretarial job was going to be very tough. She became bitter.Her son told her about a virus that had infected hisschool’s computers and that one of his disks had beeninfected. Jane took the infected disk to work and copiedit…From the perspective of the operating system and network, how should the risk be defined? What are some instances of dangers that exist in the real world as well?
- How do safety standards like "DO-178C" for avionics or "IEC 61508" for industrial systems impact software safety practices and requirements?Give some specifics on the threats to the integrity of the computer system that a malfunctioning system poses.Describe the concept of patch management and its significance in system security.
