    Da Woon November 1st  Describe the IT system
  •  
    This article tells us the air traffic controller (ATC) which helps us to have safe fly. ATC has access to sophisticated radar systems that provide an overview of the airspace they control, and they have communication tools to coordinate flight paths with the air crew. When the aircraft travel at higher speed than common modes of transport, the time available for pilots to react to a dangerous situation can be quite short. And ATC helps to aircraft approaching an airfield carefully and it checks the weather conditions for prevent pilots can't see other aircraft. ATC uses radar systems positioned at ATC facility to get a real time overview of the aircraft flying in the airspace they control. Many types of radar equipment are served for traffic on the ground. Primary Surveillance Radars (PSR) - The radar sends a directed pulse into the atmosphere, and when that pulse encounters an object it gets reflected back to the radar station. The bearing of the object with respect to the radar station and its approximate distance can be calculated by this. The radar is typically enclosed in a dome to protect it from adverse weather. Secondary Surveillance Radars (SSR) - the Secondary Surveillance Radar listens for messages from the aircraft's transponder. The radar rotates about the vertical axis, but transmits a specific signal on 1030 MHz. This signal is subsequently received by the aircraft's onboard transponder, which responds with a reply on 1090 MHz. SSR Modes - There are different modes of interrogation that compliant transponders respond to. A - The transponder responds with its squawk code, a unique identifier for the aircraft assigned by ATC comprising of four octal numbers. This code enables ATC to differentiate between the various aircraft being monitored, though it can also be used to discretely communicate the existence of an emergency situation onboard the aircraft. C - the transponder responds with the aircraft's pressure altitude, which is the altitude ab

    1. Identify the area of impact the scenario relates to. Business and employment 2. Identify the main stakeholders to the IT system. Gucci, employees 3. Identify one ITGS social/ethical concern in the article. Security 4. Describe ITGS terminology and systems. Virtual private network- a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internetas the medium for transporting data. These systems use encryption and othersecurity mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. http://www.webopedia.com/TERM/V/VPN.html Hacking- the practice of modifying computer hardware and software to accomplish a goal outside of the creator's original purpose. http://www.wisegeek.com/what-is-computer-hacking.htm Virtual servers- a Web server, that shares computer resources with other virtual servers. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer. http://www.webopedia.com/TERM/V/virtual_server.html E-mail Server - A computer server that acts as the supplier and sender of e-mails in the network. Ecommerce - Electronic commerce, business to sell and buy online electronically. Identity Theft - The stealing of and ID, or impersonating a fake person. 5. If possible, describe a solution to the concern (issue). Gucci needs to be stricter to their employees. They need to closely monitor anyone that can access the company's financial system and any vital part. By doing so, employees would not even think of hacking the system. Moreover, educating their workers into not being tricked to activate any other fraud employee accounts. Also, improving the authorization system of employees to access information with biometrics may be helpful to increase the security of their data and network system.

    On September 30th, a missile strike launched from a UAV killed Anwar al-Awlaki, al-Qaeda's most effective propagandist. This was an example of how the UAV are changing today's combat. These babies are equipped with sophisticated sensors and carry Hellfire missiles and laser-guided bombs. There may not be a man in the cockpit, but each Reaper UAV requires more than 180 people to keep it flying. A pilot is always at the controls from a ground control unit and another officer operates its sensors and cameras. UAV have become the weapon of choice over the past decade. Theres not a month that passes without reports that an al-Qaeda or Taliban leader has been killed by UAVs. There are more hours flown by America's UAS than by its manned fighter jets and more pilots are being trained to fly them than their manned equivalents. The frequency of drone stikes on terrorists in Pakistan has rose from one every 40 days to one every four days under Obama's admin. The UAV's ability to loiter for hours, minutely observe human activities while transmitting full motion video to its ground crews and can strike with pinpoint accuracy has made it the essential weapon in America's war on terrorism. Drones come in many different shapes and sizes. Predators and Reapers are the larger and more popular ones. Some are micro sized devices that imitate a bird used for eavesdropping or a mid sized plane that can be hand launched by soldiers to tell them what is happening over the hill. The medium sized UAVs would be able to defend airspace against enemy intrusion to attacking enemy air defenses. The largest UAV would operate as airborne warning and control, aerial refueling tankers, lift transports and long range bombers. The next generation of drones will also have AI, which allows them to shoot to kill. The UAS are used for "dull, dirty, dangerous, difficult or different" tasks. These tasks include surveillance missions requiring time and a degree of persistence that crews of

    manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

    Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.
