A reflective XSS attack a type of computer security vulnerability. It involves the web application dynamically generating a response using non-sanitized data from the client. Scripts, like JavaScript or VB Script, in the data sent to the server will send back a page with the script. 3. SQL Injections can be used to enter the database with administrator rights. Best way to avoid this is using Java in websites. 4. methods, including character scrambling and masking, numeric variance and nulling, rely on an array of built-in SQL Server system functions that are used for string manipulation. 5. Well co-ordinated and regulary audited security checks is the best way forword. 6. . There has been considerable debate comparing the security attributes of open source and proprietary software (Anderson, 2002). However, for a careful interpretation of the data, rigorous quantitative modeling methods are needed. The likelihood of a system being compromised depends on the probability that a newly discovered vulnerability will be exploited. Thus, the risk is better represented by the vulnerabilities which are not yet discovered and the vulnerability discovery rate rather than by the vulnerabilities that have been already discovered in the past and remedied by patches. ...

...Give a basic explanation of each step necessary to assemble a connector to a piece of fiber optic cable 1. Cable and Optical fiber preparation 2. Oven cured Epoxy application and connector assembly 3. Oven cured epoxy polishing General Guidelines The following contains information on the placement of fiber optic cables in various indoor and outdoor environments. In general, fiber optic cable can be installed with many of the same techniques used with conventional copper cables. Basic guidelines that can be applied to any type of cable installation are as follows: Conduct a thorough site survey prior to cable placement. Develop a cable pulling plan. Follow proper procedures. Do not exceed cable minimum bend radius. Do not exceed cable maximum recommended load. Document the installation. Conduct a Site Survey The purpose of a site survey is to recognize circumstances or locations in need of special attention. For example, physical hazards such as high temperatures or operating machinery should be noted and the cable route planned accordingly. If the fiber optic cable has metallic components, it should be kept clear of power cables. Additionally, building code regulations, like the National Electric Code (NEC)** must be considered. If there are questions regarding local building codes or regulations, they should be addressed to the authority having jurisdiction, such as the fire marshal or city building inspector. Develop a Cable...

...Lab 8 This chapter give as closer look into binoculars and telescopes. Hans Lippershey invented the telescope. He tested this by looking at small object in the floor. There are two different kinds of telescopes. These two different kinds of telescopes are the refractor and reflector. As the name states it the reflecting telescope uses mirrors to reflect the image and come back into the pupil. First the light goes through the front of the telescope and goes in the concave mirror. When this is done the light and image is passed on to the flat mirror and is reflected into the eye piece and the image goes into the pupil. The refractor telescope uses lenses to magnify the image. The light first goes in the primary lens and then the light goes...

...1. The first independent variable is the different luminance cues which included light, equiliminant and dark conditions, and the second independent variable was the target location either positioned on the same side (valid trial) or at an opposite location (invalid trial). The dependent variables include the reaction times of participants measured in milliseconds and the responses recorded for stimuli identification. 2. Specifically, a limitation is that the researcher only used green and red hues in his experiment instead of including the other opponent pairs, yellow paired with blue and black with white. A second weakness is the experiment only had square stimulus shapes instead of containing multiple shapes, such as bars and circles. Lastly, the researcher should have included a control group or neutral trials in order to solidify the results suggesting dual processing. 3. First, the researcher controlled for different sources of luminance information by using the same stimulus, setting the subject’s equiluminance point, and by adding random noise to eliminate the possible effect of luminance cues. Furthermore, the researcher controlled for confounding factors and bias by randomizing the trial order presented to subjects, the location of the target, and the target’s orientation. Lastly, the researcher controlled for flawed data by eliminating reaction times that deviated greatly by categorizing such times as misses and anticipatory responses. 4. This quarter, I learned that...

...Unit 8. Lab 1. Fiber Optic Connector Assembly The most critical part, the Cable and Fiber Preparation where the fiber is mounted, is the ferrule. The Ferrule is a long, thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber's cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia), stainless steel and plastic. The ferrule's job is to center and align the fiber and protects it from mechanical damage. The end of fiber is at the end of the ferrule, where the fiber end is polished smooth either flat or with a curvature. The ferrule is mounted in the connector body and then the connector body is attached to the fiber optic cable structure. Finally, a strain-relief rubber boot protects the connector-cable junction. Fiber optic connectors usually do not have the male-female polarity. Most fiber connectors are male only. Instead, fiber connectors mate to each other in fiber adapters, which are often called mating sleeves or coupling receptacles. Fiber optic adapters used to mate different connector types such as a FC connector to a SC connector are called hybrid adapters. Although this approach requires the use of separate adapters, it otherwise reduces fiber connector inventory requirements since now you need to stock one type of connector only. Another advantage is that fiber adapters can be designed to mate one type of connector to another, which is a big...

...Unit 8. Lab 1. Fiber Optic Connector Assembly Fiber Stripping “The outer sheath of fiber cables can be removed using electrical cable stripping tools, and scissors or a razor blade can trim the Kevlar strength member. However, the fiber coating must be very carefully removed to avoid damaging the fiber, surface flaws and scratches are the cause of most fiber failures. The coating can be removed using fiber strippers.” (Newport, nd) Fiber Termination “End-face surface quality is one of the most important factors affecting fiber connector and splice losses. Quality end-faces can be obtained by polishing or by cleaving. Polishing is employed in connector terminations when the fiber is secured in a ferrule by epoxy.” (Newport, nd) Fiber Cleaving “Fiber Cleaving is the fastest way to achieve a mirror-flat fiber end and it takes only seconds. The basic principle involves placing the fiber under tension, scribing with a diamond or carbide blade perpendicular to the axis, and then pulling the fiber apart to produce a clean break.” (Newport, nd) “Once the optical fiber is terminated with a particular connector, the connector end-face preparation will determine what the connector return loss, also known as back reflection, will be. The back reflection is the ratio between the light propagating through the connector in the forward direction and the light reflected back into the light source by the connector surface.” (Newport, nd) “Minimizing back reflection is of great importance...
