where the system IDPS was alarmed but no attack ever occurred. The false negative is where an actual attack occurs and the IDPS isn’t alarmed at all. The least desirable would definitely be the false negative‚ if an attack does occur and the IDPS doesn’t even alarm well what’s the point in even having it if it isn’t going to alarm. 2. What is a honeypot? How is it different from a honeynet? A honeypot is a decoy system that will lure potential hackers away from the networks critical systems. A honeynet

Dell Case Dell is a major player in the computer industry. Michael Dell pioneered the direct selling system that catapulted the firm to the top position in the industry. As the case details‚ controls systems play an important role in Dell’s success. For example‚ the company makes a mere $12 profit on their low end machines that sell for $299. It is important to control assembly and delivery lest these wafer thin margins are reduced even further. However‚ as the case points out‚ Dell’s single-minded

CPSC 313 Introduction to Computer Systems Summer 2014 Homework 2 1. [2] What are asynchronous‚ deferred‚ and disabled cancellation in pthreads? What makes them different? 2. What is the role of the contentionscope for pthreads? How does it affect the execution of pthreads? 3. Assume you have a system that does not provide a usleep(unsigned long usec) call to suspend the execution of the thread for a given amount of time‚ say in µsecs. How would you implement this function using condition variables

Our nature has the most complex system‚ for example‚ the ecosystem. The elk overpopulation problem of Yellowstone National Park in the article “Embracing Complexity” indicated that our nature has a set of way to operate‚ but once humans intervene‚ the system will be distracted and go astray from its original pass. However‚ the rangers did not understand the whole complex system of our nature‚ instead‚ they did what they saw right in their eyes and fed the elks‚ thus caused the significant increase

highly-developed transport system‚ enabling everyone to reach any place on earth in a reasonable time. To this end‚ traffic control systems have been developed using IT. No traffic control system without IT would be imaginable today. We only need to think of an airport‚ large shipping port‚ or main railway station. Even road traffic would collapse in any sizeable town if the computer controlling the traffic lights broke down. There are an increasing number of traffic control systems on the German autobahn

WHAT IS OPERATIONS MANAGEMENT? Production: The creation of goods and services Operations Management: The set of activities that creates value in the form of goods and services by transforming inputs into outputs. Operations management is one of three main business functions involved in the creation of goods and services (i.e.‚ Operations Function‚ Marketing Function‚ Finance/Accounting Function). These functions all interact and share information with one another‚ as the diagram on the

Executive Summary: Operations and processes are the activities of each organisation that drive their output. This assignment examines the operation and processes of the IT services of a semi-government organisation. It demonstrates the current state of the operations and provides comprehensive analysis of its processes. It demonstrates how the operations performance impacts the strategic outcomes of the organisation. The study further provides insights in the operations supply network configuration

1. Because Ohari’s produces more of a variety of coffee in a smaller volume‚ they would most likely use a batch process system. A batch process system is classified under an intermittent process‚ meaning it has a lower volume but produces more products (in small lot sizes). Folgers would use line-flow process system‚ such as an assembly line or continuous process. This kind of process is used for higher volume production with more standardized products‚ such as what Folgers produces. 2. Ohari’s

Problem 6.1 Continental Airlines (CA) is reluctant to begin service at the new Delayed Indefinitely Airport (DIA) until the automated baggage-handling system can transport luggage to the correct location with at least 99% reliability for any given flight. Lower reliability will result in damage to CA’s reputation for quality service. The baggage system will not deliver to the right location if any of its subsystems fail. The subsystems and their reliability for satisfactory performance during operation

A system has 12 external inputs‚ 24 external outputs‚ fields 30 different external queries‚ manages 4 internal logical files‚ and interfaces with 6 different legacy systems (6 EIFs). All of these data are of average complexity‚ and the overall system is relatively simple. Compute FP for the system. 6.
