Not many years ago, most computers were carefully guarded mainframes, held tightly in the hands of skilled professionals. The systems and their guardians combined to provide ironclad protection of the organization’s all important data.

Generally there are three types of attack that could potentially affect your business: †¢ Information theft: Stealing company confidential information, such as employee records, customer records, or company intellectual property †¢ Information sabotage: Changing information in an attempt to damage an individual or company’s reputation, such as changing employee medical or educational records or uploading derogatory content onto your Web site †¢ Denial of service (DoS): Bringing down your company’s network or servers so that legitimate users cannot access services, or so that normal company operations such as production are impeded Firewall Technologies The ICSA (International Computer Security Association) classifies firewalls into three categories: Packet Filter Firewall Every computer on a network has an address commonly referred to as an IP address. A packet filter firewall checks the address of incoming traffic and turns away anything that doesn’t match the list of trusted addresses. The packet filter firewall uses rules to deny access according to information located in each packet such as: the TCP/IP port number, source/destination IP address, or data type. Restrictions can be as tight or as loose as you want. An ordinary router on a network may be able to screen traffic by address, but hackers have a little trick called source IP spoofing that makes dataShow MoreRelatedDiscussion Board Essay678 Words   |  3 Pagesfollowing: Assuming the company had a firewall, why didnt it stop the intruders?

Unit 4 IP Date: February 3, 2013 1. What two policies could you use to reduce the total amount of emissions? The first policy that I would put in place is a reduction of hours available for the plants to run. I think that by reducing the available operation times, you will have less production and therefore less pollution. We will write a custom essay sample on Unit 4 Ip or any similar topic only for you Order Now This will ultimately force the company who definitely needs all the time they can to produce their products, to find a cleaner way to get the job done. The second policy that I would put in place would be a limitation on the amount of certain chemicals that can be used. I would limit the use of chemicals that cause the most emissions problems and invoke fines on anyone who goes over the limited usage. This would 2. Why do you think they each would work? As I mentioned above, the first policy would force the company to find a better way to produce power without the dangers of the externalities polluting the air. The company will need to operate at a certain level to produce power, so they would have no other choice but to find a way to reduce emissions. With the second policy would only work if there were fines associated with using more than the allotted amount of chemicals that cause pollution. We could have policies all day long, but if there are no consequences or they don’t have anyone to answer to then things will not change. They will continue to produce at levels that are dangerous to the people around them. 3. What would the benefits of each action be (besides emissions reduction)? In addition to the reduction of emissions, we would also gain control of the quality of energy being produced. There would be a consistent product that was produced cleanly and it definitely would be better for the health of the people that live around the power plants. The health benefits are fewer illnesses such as cancer, upper respiratory infections, and skin diseases associated with the release of externalities. 4. What would the costs of each action be? With the first policy if it is put into place the power plant is definitely going to lose money. If we limit the amount of hours of production, they will definitely not be able to meet whatever quotas they have already put in place. They will produce less and this could affect their bottom line. With the second policy, it may cost them a little more to put into place different procedures to measure the amount of certain chemicals released into the air. It won’t be nearly as costly as reduced hours would be, but the minimal cost would definitely be worth it. 5. How would you decide what was the best level of emission reduction? I would determine what levels of certain chemicals are safe for the neighborhood through testing and with research that has already been done. There are already studies on what is safe and what could harm a population of people or animals that are located near a power plant. References: Power Plant Pollution Control. (n. d. ).

Pyrite hypothesis = If pyrite is added to a beaker with 100mL of water, then it will reduce the pH over 48 hours. b. Coal hypothesis = It activated carbon is added to a beaker with 100mL of water, then it will increase the pH over 48 hours. 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. a. Pyrite hypothesis accept/reject = I would accept the hypothesis, seeing as how the pH did in face lower from 6 to 2. b. Coal hypothesis accept/reject = I would consider this hypothesis to be correct as the pH increased from 6 to 10. 3. Based on your data, what effect do you predict coal mining has on the environment? Answer = Coal mining basically removes the coal from the ground which would hinder the Earths ability to reduce its acidity as the charcoal helps raise and ultimately balance the planets pH. We will write a custom essay sample on Energy Sources and Alternative Energy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The soils pH greatly affects the way planet life ingests nutrients and flourishes, which allows humans to harness essential components from nature. 4. What can be done to prevent mine drainage from damaging the ecosystem? Utilize at least one scholarly resource to support your suggestions. Answer = According to World Coal, there are mining operations underway to help refresh damaged land. This is done by shaping the previously mined soil, then packing it and laying it back down in such a way to vegetate healthily again (Coal Mining the Environment, n. d. ).

Develop hypotheses predicting the efficiency of solar energy from direct sunlight against the 4 variables tested? Direct vs indirect hypothesis = If the solar panel is faced towards direct sunlight, then the motor will move faster. Direct vs reflected hypothesis = If the solar panel is faced towards a reflected sunlight, then the motor will move slower. Direct vs shaded hypothesis = If the solar panel is placed in a shaded location, then the motor will not move at all. Direct vs filtered hypothesis = If solar panel is covered with a colored filter, then the motor will either move the same or slower depending on the color. 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. Direct vs indirect accept/reject = Direct vs reflected accept/reject = Direct vs shaded accept/reject = Direct vs filtered accept/reject = 3. Does increased exposure to the sun’s light produce more current? Explain how you know this based on your data? Answer = 4. How could you increase the electricity generated by a solar cell during the day, when the sun’s angle is constantly changing? Answer = You could attach the solar panel to a device that move in correlation with the suns movement throughout the day, maximizing the efficiency of the solar panel all day. 5. Based on your data, could adding filters to solar panels increase the solar energy produced? Explain how you know this. Answer = References Coal Mining the Environment.
