Choose a recent IS security breach or service outage that has been in the media - Essay Example As a result of this breach records of more than 40 million workers were stolen. Additionally, the significant influence of such cyber attack that stole data and information on the businesss Secur-ID verification tokens is yet being debated. According to the management of RSA, two separate hacker groups working in the organization with an overseas supervision to begin a set of spear phishing based security attacks beside RSA workers, demonstrating like people the workers relied, to infiltrate the businesss network. In this scenario, EMC stated that in last July it had used-up as a minimum $66 million on remediation. However, RSA administrative staff believes that there was no harm to clients networks. Additionally, the management of RSA has not supported the matter by initially being unclear regarding both the security based attack vector and (more notably) the information that was stolen (Armerding; Bell; Cate). In addition, it was simply a matter of time previous to following security based attacks on Lockheed-Martin, L3, and others happened, all of those are supposed to be particularly supported by RSA breach. In this scenario, many people believe that it is just a psychological damage. Without a doubt, this security breach was very harmful and critical just not simply because of the damage it caused, however as well in the scenario of the miserable danger that it drove into each CIO who misplaced the warm-and-fuzzy situation that the reliability of his/her enterprise verification model was undamaged (Armerding; Bell; Cate). Moreover, the bank had to face the loss of more than $100 to put back identification tokens that left their computers susceptible to spying. According to the management of RSA, clients have suggested them to follow a number of prevention practices. However, the bank is seriously considering the suggestions of their customers. And it is currently

Chemistry class xii project Essay Theory What is rust? Rust is the common name of a compound, iron oxide. Iron oxide, the chemical Effie, is common because iron combines very readily with oxygen so readily, in fact, that pure Iron Is only rarely found In nature. Iron (or steel) rusting Is an example of corrosion an electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). Causes When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. As oxygen combines with the metal, electrons are liberated. When they flow through the electrolyte to the cathode, the metal of the anode disappears, swept away by the electrical flow or converted into metal actions in a form such as rust. For iron to become Iron oxide, three things are required: Iron, water and oxygen. Heres what happens when the three get together: When a drop of water hits an Iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin o break down Into Its component pieces hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process freeing electrons. The electrons liberated from the anode portion of the iron flow to the cathode, which may be a piece of a metal less electrically reactive than iron, or another point on the piece of Iron Itself, Consequences Rusting has a number of effects on metal objects. It makes them look orange and rough. It makes them weaker, by replacing the strong Iron or steel with flaky powder. Some oxides on some metals such as aluminum form Just a thin layer on top which lows down further corrosion, but rust can slowly eat away at even the biggest piece of iron. If a piece of Irons strength Is important for safety, such as a bridge support or a cars brake caliper. It Is a good Idea to Inspect It for rust damage every now and then. Rust also can cause metal parts that are supposed to slide over one another to become stuck. Rust can make holes In sheet metal. Rusty car mufflers sometimes develop holes in them, and the sheet steel making the outer bodies of cars will often rust through, making holes. Rust Is a lot less magnetic than Iron. An iron magnet will probably still work almost as ell when It has a thin coating of rust on It, but If It has rusted so badly that most of the metal is gone, then it will not work very well as a magnet. 1 OFF which is a metallic conductor. So if some electrical connection is made with iron, its likely to go bad when the iron surface rusts. Rust is associated with degradation of iron-based tools and structures. As rust has a much higher volume than the originating mass of iron, its build-up can also cause failure by forcing apart adjacent parts ? a phenomenon sometimes known as rust packing. It was the cause of the collapse of the Missus river bridge in 1983, when he bearings rusted internally and pushed one corner of the road slab off its support. Rust was also an important factor in the Silver Bridge disaster of 1967 in West Virginia, when a steel suspension bridge collapsed in less than a minute, killing 46 drivers and passengers on the bridge at the time. Prevention and Protection Because of the widespread use and importance of iron and steel products, the prevention or slowing of rust is the basis of major economic activities in a number of specialized technologies. A brief overview of methods is presented here; for detailed overage, see the cross-referenced articles. Rust is permeable to air and water, therefore the interior metallic iron beneath a rust layer continues to corrode. Rust prevention thus requires coatings that preclude rust formation. Some methods of prevention of rusting are as follows: Gallivanting:- Globalization consists of an application on the object to be protected of a layer of metallic zinc by either hot-dip gallivanting or electroplating. Zinc is traditionally used because it is cheap, adheres well to steel, and provides catholic protection to the steel surface in case of damage of the zinc layer. In more corrosive environments (such as salt water), cadmium plating is preferred. Coating and Painting:- Rust formation can be controlled with coatings, such as paint, lacquer, or varnish that isolate the iron from the environment. Large structures with enclosed box sections, such as ships and modern automobiles, often have a wax-based product (technically a slashing oil) injected into these sections. Such treatments usually also contain rust inhibitors. Covering steel with concrete can provide some protection to steel because of the alkaline pH environment at the steel-concrete interface. Humidity Control:- Rust can be avoided by controlling the moisture in the atmosphere. An example of this is the use of silica gel packets to control humidity in equipment shipped by sea. Metal Coupling:-Len this method, the iron is coupled with other metal and if the metal is above iron in electrochemical series(meaner more electrostatics)then in the galvanic cell is formed by the contact of the iron and that metal, iron will go under reduction it will be safe from rusting. If the metal is below iron in electrochemical series then iron will go under oxidation and rusting will be facilitated.

growaw Unfulfilled Edna Pontellier of Kate Chopins The Awakening Ess

Unfulfilled Edna of The Awakening  Ã‚   As evidenced in Kate Chopin’s The Awakening, and other novels of the 1800’s, women writers of this period seem to feel very repressed. Leonce Pontellier seemed to be fond of his wife, and treated her as one would treat a loved pet. In the beginning of the story it describes him as looking at her as a â€Å"valuable piece of personal property†. He does not value her fully as a human being more as a piece of property. However, he expects her to be everything he thinks she should be. Her children also expect total sacrifice from her. She obviously feels unfulfilled in life and inadequate in many facets. She does not feel like an artist, she does not feel like a satisfied wife or mother. Since she does not feel like she has an actual life, that is why it is easy to kill herself. It is at the end when she views the sea as the rolling,endless meadow that the sees a life without constrictions. She finally feels free and at peace. The Awakening is an emotionally unsatisfying story. It is the story of a women, Edna, who tries unsuccessfull...

Network Design Project

Situation in which the Project Exists: This project is for a residential data communication network. The proposed network is designed to connect 2 workstations and 1 printer. It will provide internet access as well as multiple email addresses. The client has approved an initial investment of $5,000 to implement the networking project. The two workstations will be two HP Pavilion Laptops with AMD Turion II Dual Core Mobile processor, each for $529. 99. The printer will be a PIXMA Wireless multifunction printer/copier/scanner for $99. The client desires to have a mobile network with the ability to work virtually anywhere in the house. The laptops both come with internal wireless adapters, 500gbytes of hard drive space, and they feature 2 processing cores with 2. 2GHz processor speed per core. For multitasking power the laptops come with 4GB DDR2 DIMM memory, expandable to 8GB. The wireless printer prints up to 26ppm in black, and up to 17 ppm in color. It also prints, copies and scans for convenience. The printer also has built-in memory card slots that support various card capacities and sizes. The network will be designed to accommodate the client’s mobility needs and business/operational objectives. We have decided to implement a wireless LAN Architecture to provide the customer with maximum mobility. We have decided to use the Verizon FiOs Network which comes with a wireless router, and downloads up to 50 Mbps and uploads up to 20 Mbps for $139. 95 per month. All Verizon High Speed Internet packages include one account with eight additional sub-accounts, totaling nine accounts. A wireless router is a wireless access point with several other useful functions added. The router converts the signals coming across the Internet connection into a wireless broadcast, and steers data in an intelligent way, eliminating a lot of the sluggishness found in typical peer-to-peer networks. (Networks that don’t have servers are peer-to-peer networks because each computer has equal ranking) Like wired broadband routers, wireless routers also support Internet connection sharing and include firewall technology for improved network security. A key benefit of both wireless routers is scalability. Their strong built-in transceivers are designed to spread a wireless signal throughout the home. A general rule of thumb in home networking says that 802. 11b and 802. 11g WAPs and routers support a range of up to 300 feet, but obstructions in a home such as brick walls and metal frames can reduce the range of a Wi-Fi LAN by 25% or more. The router will be placed in an optimal location away from microwave ovens, 2. 4 GHz cordless phones and garage door openers which can all cause signal interference. In densely populated areas, wireless signals from neighboring homes can sometimes cause signal interference. This happens when both households set conflicting communication channels. When configuring an 802. 11b or 802. 11g router, you can change the channel number used. The default administrator password and username for the router will be immediately changed. All Wi-Fi equipment supports some form of encryption, and we will be using the128-bit WEP Encryption by assigning a WEP passkey. The passkey should be unique and long. For extra security we will be changing the default SSID or network name, which identifies the network. This should also be unique. Most wireless network routers contain the ability to filter devices based on their MAC address. By enabling MAC Address Filtering, this will allow the router to keep track of the MAC addresses of all devices that connect to it, and only allow connections from those devices. The MAC address is a unique identifier for networking hardware such as wireless network adapters. The SSID broadcast feature will be disabled as well. Many wireless routers routinely transmit the WiFi network name (SSID) into open air. This roaming feature is unnecessary as it increases the likelihood someone will try to log in to the network. The two laptops and the wireless printer will all be assigned a static IP address. DHCP will be turned off from the router to prevent network attackers from easily obtaining a valid IP address from the network. The Verizon network router comes with a built-in firewall capacity. Firewall programs can be very effective at keeping intruders out of the network and out of your computer. We will ensure that the router’s firewall is turned on, and for extra protection we will install and run personal firewall software on each computer connected to the router. Next the printer software will be installed on each computer and connectivity will be ensured. Implementation is complete once all nodes are connected to the router and functioning correctly.

Dickens’ and Bronte’s Definition of Class Essay

People of the lower classes in Charles Dickens’ Oliver Twist and Charlotte Bronte’s Jane Eyre have no way of achieving higher status unless they come across a miracle, such as receiving a previously unknown inheritance. This is shown in both the novels of Jane Eyre and Oliver Twist. Both of the main characters grow up in similar situations; they are both orphans and because of that fact they are treated like they were criminals from birth. Although Jane is better off than Oliver in the places that she lives, they both go through some of the same emotions throughout the novels. Both Dickens and Bronte lived in the same time period and their novels were published within ten years of each other. In their novels they show the England they perceived as one that is overly obsessed with class. Neither of the authors agreed with this obsession and criticized it in their own ways. Dickens showed this by using sarcastic remarks when describing the rich, and (as well as Bronte) characterized almost all of the upper class as being immoral in one way or another. They put the point across that just because a person is born poor doesn’t make them any less intelligent, polite, or morally inapt. In the novel of Oliver Twist, Dickens describes that poor people are just as intelligent and good as the rich, it’s the way the rich treat them that forces the poor to steal. Through out the novel he sets examples of how intelligent and good Oliver Twist is treated like an animal just because he is an orphan. One of many examples of this is Mrs. Sowerberry’s reaction when her husband gets Oliver to come over to help with the undertaking business and to live with them. She talks about Oliver as though he is an animal, â€Å"I see no saving in parish children, not I; for they always cost more to keep than they are worth.† (p30) This theme is similar in Jane Eyre. Bronte shows that orphans, unless they have money, are viewed as the lowest class of a house hold. Jane encounters this throughout her childhood, it was first brought to her attention by Mrs. Reed who says, â€Å"†¦you are less than a servant, for you do nothing for your keep.† (p69) Like Oliver, Jane does nothing to deserve such a harsh classification, except for being born. They both try their best to follow the rules and to be good people. Poor people basically have two choices to live in 19th century England as shown in Oliver Twist they could live on the streets by begging and/or stealing, eventually being put into jail or to death because of the anti begging laws and harsh penalties for stealing. The other choice the poor have is to work in the workhouses for no money, scarce food, and poor treatment. Upper class England created these workhouses to better the lower class by teaching them to be humble, have discipline and good morals. Ironically the workhouses created just the same thing they intended to get rid of, criminals. The food was so scarce that it forced them to steal and fight, and the treatment of the children were so bad it made them alienated from normal society. Bronte describes the same attitude of the upper class while Jane is at Lowood, though it is not as extreme as the workhouses Dickens talks of. The girls of Lowood were all orphans and because of that they obviously had to be corrected for they were naturally going to turn into bad people. So Mr. Brockelhurst thought that good morals come from no food, plainness, lack of necessities and constant humiliation. This produced an â€Å"every man for themselves† society among the girls when the faculty was gone. The older girls got to be the closest to the fire when it was cold, and when ever they had a chance they would take food from the younger, weaker girls. â€Å"From this deficiency of nourishment resulted an abuse, which pressed hardly on the younger pupils: when ever the famished great girls had an opportunity, they would coax or menace the little ones out of their portion.† (JE BV p122) If things had not changed for the better in that school Jane may have become a very different person than she turned out to be. Though both Jane and Oliver are supposed to be immoral and no good orphans in 19th century England’s eyes, they have the highest set of morals than any other person in their stories. Oliver never wants to steal from anybody and never starts a fight unless his family is concerned. Even though all of the people he hung out with were thieves he just couldn’t do it, stealing horrified him and he wanted no part in it. Jane refuses to marry Rochester because she believes it to be wrong to stoop herself down to a mistress. She also thinks it is wrong to marry for money and not love. Jane displays this  by turning down St James although he has a high standing in society, she feels he is a wicked man and would not be happy if she were to marry such a man. The immoral people in both novels, are the upper class who believe themselves to be better than the main characters. Mr. Bumble, for example, marries Mrs. Corney because of her wealth and nothing to do with her as a person. When he came to flirt with her he checked around her apartment for expensive things that would distinguish her as wealthy. â€Å"He opened the closet, counted the tea-spoons, weighed the sugar-tongs, closely inspected a silver milk-pot to ascertain that it was of the genuine metal†¦and spreading himself before the fire with his back towards it, seemed to be mentally engaged in taking an exact inventory of the furniture† (p185) To make the situation even more ironic, Mrs. Corney is only wealthy because she stole the money for the poor people’s food and clothing and kept it for herself. She jokes about how the cats have a better life than those of the people she looks after. By the end of the story the couple is described as miserable. In the novel of Jane Eyre, Mr. Brockelhurst is supposed to be a religious and moral man, but he deprives the children of food and clothing to benefit his own pocket. He is a hypocrite also for example, he tells a girl with curly hair to get it cut off, when his own daughter has the same kind of curly hair. His attitude and the attitudes of other middle upper class people are all the same of that time. They think that they deserve to have the curly hair and the extra money at the expense of the poor, because they are physically and divinely better than them. Though all of this injustice is happening to the poor, they have no way to fight back. They don’t even have rights in court houses. When Oliver is brought to trial for pick pocketing, the judge, Mr. Fang, sentences Oliver even though there is no hard evidence and a testimony saying he is innocent. Oliver can not even talk in his own defense, partly because he is so tired and hungry and party because the magistrate wouldn’t give him the chance to. If the book keeper had not demanded to speak in Oliver’s defense, Oliver would have surely died. When Jane was living with her aunt she had no say at all in what was done with her. She could be beat by John Reed and tormented  by her aunt Reed and she would had to take it. Marriage and class is a subject that both Bronte and Dickens speak of. They both believe that the English tradition of marrying for money and status were absurd and that marrying for love was the true way to happieness. This is exhibited in many examples in Oliver Twist. For one, Oliver is born out of true love and he turns out to be a good boy and always makes moral decisions. Oliver’s half brother, Monks was born of a fixed, loveless, financial marriage, and he turned out to be evil and mischievous his whole life. Dickens also describes the love between Rose and Harry. The people of England were so critical on who one married, that Rose didn’t want to marry Harry because she felt that people would think that she slept with him before marriage just to get his money and that Harry would be shunned by his peers for marrying her. When they finally did marry, they were very happy with each other. As opposed to Bumble’s marriage which turned out to be miserable for him and his wife. Jane ends up marrying Rochester out of love rather than St James for money and status. But she was more comfortable in marrying him when that she got her money because she felt like an equal to him, rather than a servant. Dickens and Bronte touch on the same subjects through out their novels and have a lot of the same view points. The time that they wrote was one of extreme pettiness and cruelty. It would be safe to say that both authors wrote for different reasons than just to entertain. Points were made about the absurdity of marriage, of being â€Å"born† into divine upper or lower class, and of horrible ways humans treated each other just because they thought they were better. Both novels had the few good people that helped out Oliver and Jane so that they could get by in life long enough to receive their long lost inheritance. These books show that poor people are equal to the rich ones in intelligence, moral values, and politeness. They also made evident that the way society was running in those days was hurting way too many good people of England.
