...15OCT14 NT1110-1 Task 1 The LGA 1156 is known as Socket H2, the LGA 1155 CPU socket is used with Intel's “2nd Generation Core* i7/i5/i3 series” of desktop microprocessors codenamed Sandy Bridge. This 1155-circuit socket is a replacement of its predecessor – the LGA 1156 Socket (or Socket H1) – which mates with the Nehalem* processor. Its purpose is to connect the motherboard to the, without this connection the computer would not work. The Intel H55 Express Chipset. The GIGABYTE H55N-USB3 motherboard was built to support Clarkdale (Core i3/i5) processors as well as Lynnfield (Core i5/i7) CPUs. New to the H55 platform is a Direct Media Interface (DMI) that connects between the processor and chipset. The purpose of the H55 is to provide the interface for the PCI Express lanes on the motherboard The Gigabyte GA-H55M-UD2H motherboards interesting information is its Unique On/Off Charge delivers the best recharging capability to iPad, iPhone and iPod Touch. It supports six devices without the need for drivers to be installed before being fully functional. The high performance DAC has 108 dB signal to noise ratio playback quality and it has an innovative Smart 6 technology for smarter PC management. Task 2- The AMD 700 chipset series (also called as AMD 7-Series Chipsets) is a set of chipsets designed by ATI for AMD Phenom processors its purpose on the motherboard is to link the computer systems hardware to the processor.

...Lab #4 Operating Systems: Hardening and Security March 1st, 2015 Lab Assessment Questions & Answers 1. What is the one thing that a virus, a worm, spyware, and malicious code have in common? What are the differences among these three threats: a virus, a worm, and spyware? A virus, worm and spyware all have in common that they replicate themselves into the network’s system. Some of the differences between the three are that worms can edit files, viruses need a host file to propagate itself and a spyware can steal very sensitive information within the network. 2. How often should you update your antivirus protection? You should update your antivirus protection daily to always keep your network secured. 3. Why is it a best practice to have and to carry an antivirus boot-up disk or CD? It is best practice to use an antivirus boot-up or CD because it can bypass any files that are meant to protect the malware from being detected during scans. 4. In a corporate environment, should new antivirus definitions be installed as soon as they are available? Yes, in a corporate environment antivirus programs should be installed right away to protect the company’s files. 5. Is the manual quick scan good enough protection for a system? No a manual quick scan is not good enough protection for a system the files also have to be deleted. 6. What best practices for the workstation domain that can mitigate the risks and threats caused by malicious code...

...740 words. Question 3: “Describe the function of the following Docker commands and briefly explain the purpose of each of the parameters. docker run –d –p 8080:5000 –v $(pwd)/data:/data –name container1 lab4 Docker is a software containerization platform, that runs processes in isolated containers. The docker run command is used to define the containers resources at runtime. When the command is run, the container process is isolated. It is separate from the host itself. The –d command is an option run by Docker to communicate whether the container should be run in “detached” mode or in the “default mode”. The –d command signifies that the container should be run in detached mode, meaning the container will be run in the background. The next option used is –p. This is used to publish all exposed ports to the host interfaces. Docker, in turn, ‘binds’ each of the exposed ports to a host port, addresses of the published ports are 8080:5000....

...Unit 3 Lab4 Chris Hann Zy Powell 1. Dictionary attacks and rule-based search attacks. 2. Cross-site scripting allows for attackers to bypass client-side security mechanisms normally forced on web content by current browsers. 3. You can do this by disabling scripting when it is not necessary. Do not trust links to other sites on email or message boards, and do not follow links from sites that lead to security-sensitive information directly through its address. 4. The attacker can use redirect vulnerability, where a webpage uses a script to redirect the user somewhere other than the intended site. So then the hacker takes advantage of the script and you are sent to an external page instead of an internal one. 5. It can be denial of access, data loss or corruption, and unnecessary account privileges. 6. Blind SQL injection ask question that can only have a yes or no answer. Yet with normal SQL injection ask questions that will confuse the applications into returning answers in error message and. 7. Because XSS is a hacking technique in which a malicious user enters a short snippet of JavaScript into a textbox so that this script will be saved in the database. Therefore when a user retrieves and displays this later, the browser will execute the script. 8. When a user tries to enter their credentials, the url is explaining that the password is wrong. 9.

A corporation ling its rst return must annualize its income if the tax period is less than 12 months. A taxable year may be as short as one day and may exceed 366 days. Under no circumstances may a corporation change its scal year without IRS permission. A taxpayer engaged in two or more separate and distinct businesses may use different accounting methods for both businesses. A grocery store may use the cash basis of reporting sales. In general, a CPA on the cash basis method will never have a bad debt deduction. A cash basis taxpayer may deduct prepaid business expenses currently. Both cash and accrual basis taxpayers will be taxed on a dividend when it is actually received. Computing cost of goods soldand being on the accrual basis are independent of each other. If, in the IRSs opinion, the taxpayers books do not clearly reect income, the IRS may revise them so that they do. Taxpayers must generally obtain the permission of the IRS to change accounting methods. A correction of an error in a tax return is usually considered a change in accounting method. The IRS can require a change in accounting methods if the method used by a taxpayer does not clearly reect income. IRS permission is not required for a change from FIFO to LIFO. The installment method cannot be used unless the total selling price...
