Firewalls and Intrusion Detection Systems Assignment

Firewalls and Intrusion Detection Systems - Assignment Example What are the similarities and differences of these two systems? Intrusion detection systems are software applications or devices that detects and monitors malicious activities of violations of policies provided. In addition, the application provides reports and information to management stations. The application has different ways and mechanisms that may detect network traffic from different sources. In general, intrusion detection systems focus on detecting network incidences, logging information of users and reporting log in attempts (Ross, 2001). Moreover, companies use the systems to monitor their existing security systems. This is done by detecting issues with security policies and creating documentation on existing network issues. In addition, the system may provide recommendations on how to update existing security policies. The main objectives of IDS are analyzing and monitoring system activities and users, taking part in system audits, analyzing the safety of content used and required, detecting unusual activities and comparing partners to malware patterns. One major weakness of the system is that it must contain human operations which may hinder the effectiveness of automated functionality (Verma, 2008). On the other hand, firewalls are also used to increase the effectiveness of network security approaches. Firewall protects network security systems from access from unauthorized sources. Verma (2008) is of the assumption that firewall protect security prior to their access. The author further points out that the security system relies on its ability to protect access and distortion before threat is launched. To increase the effectiveness of the system, they are regularly updated to be able to identify advanced network threats. Firewall security systems also ensure the safety of the network connection used in a business. With a protected security firewall detects both incoming and outgoing packets.

Melyssa Arner Scott Robinson Western Civilization II 18 February 2014 1. Analyze and evaluate the life of Martin Luther and his influence on the Reformation. Before bringing about the Reformation, Martin Luther started out his life in Saxony.He was raised by a strict father who wished for his son to become a lawyer. Instead of achieving this, Martin Luther, due to a promise to St. Anne, became a man of the cloth. Those above Luther’s station later enrolled him into the faculty of the university in Wittenburg. It would be at Wittenburg that Luther would change the way of the church, later to be called the Reformation. Luther believed that faith was a way of salvation, which became known as the â€Å"justification by faith†. Martin Luther also began to question the clergy of the church, who made the public pay for indulgences in order for their souls to be freed. Due to his beliefs being ignored, Luther created his â€Å"Ninety-five Theses†. Through these theses, Luther’s beliefs spread throughout the lands of Germany. His ideals about the church passed onto the German people and his acts would later influence the happenings of the Reformation. 2. List and discuss the various religious wars in Europe in the 1500s and 1600s concluding with the Thirty Years War. King Philip II of Spain was a strong supporter of Catholicism. He controlled not only Spain, but also the Netherlands, Southern Italy, and Burgundy. His wife, Mary, was the queen of England. The two of them worked to bring England back to Catholicism but many people were against this.

The inhabitants of Africa had their world changed when Europe decided to venture to the New World. While the Native Americans were pushed from their land, the Africans were taken away from theirs. The Europeans needed another set of hands to perform labor and the Africans played this part. Even though Africans could be linguists and guides for the white people, they were mostly used for housework and as farm hands. Africans were forced into slavery and owned by the Europeans. Similar to the Native Americans, the Africans were forced to convert to Christianity. Their religious views were not allowed in the New World. The Africans were not only forced to convert to Christianity but also their way of life. Africans had to dress and speak like the Europeans in order to survive.

Dimmesdale Essay -- Literary Analysis, Nathaniel Hawthorne

Arthur Dimmesdale, a character of high reputation, overwhelmed by guilt, torn apart by his own wrongdoing, makes his entrance into history as the tragic hero whose life becomes a montage of pain and agony because of his mistakes. The themes leading to Dimmesdale’s becoming a tragic hero are his guilt from his sin, and his reluctance to tarnish his reputation in the town. Guilt plays a huge role in defining Dimmesdale as a tragic hero. Dimmesdale has understood that by not revealing his sin, he has doomed himself. This also connects with the constant struggle with Chillingworth. The mysteries of Dimmesdale’s guilty heart entice Chillingworth to delve into his soul and reveal what has been hidden, causing Dimmesdale great pain and suffering. His guilt is taking over, causing him to inflict pain upon himself while also experiencing true and meaningful suffering. Guilt is not the only theme in the novel that help to characterize Dimmesdale as a tragic hero, but reputation and authority in the community also help to characterize him as a tragic hero. Arthur Dimmesdale has a grand reputation and authority in his community, which worsens his downfall. The respect he had from his community makes them hurt worse when they see his decline. His excessive pride makes him ignorant to most, until the end when all things go downhill. He also made a life altering decision of whether to stay and face his guilt, or to run away from his mistakes. Arthur Dimmesdale, from Nathaniel Hawthorne’s The Scarlet Letter, is an example of a tragic hero because of the downfall brought about by his guilt and necessity to uphold his authority in the town. Hawthorne uses dark diction and kinetic imagery to emphasize how Dimmesdale’s guilt causes him to experi... ...eluctance to give himself up, and must have Hester do it for him. This guilty diction displays his longing for redemption, but how he cannot do it himself. He longs for a chance to right his wrongs, but his pride gets in the way. His hubris does not allow him to defame himself in the community and Hester must expose him. Terrence Martin explains this by saying that â€Å"he cannot surrender an identity which brings him the adulation of his parishioners, the respect and praise of his peers† (Martin 93).Martin explains how Dimmesdale cannot let his reputation in the town be tarnished, and how his hubris keeps him from confessing his sin. He cannot stand to lose the â€Å"adulation of his parishioners, the respect and praise of his peers.† Dimmesdale’s excessive pride over his authority in the town clouds his judgment and makes his downfall that much more tragic.

? Explain the Continued Fascination with Katherina in ‘the Taming of the Shrew’

?explain the continued fascination with Katherina in ‘The Taming of the Shrew' Audiences continue to be fascinated and relate with Katherina because of the struggles she faces with not fitting into a very concise, social mould. There's no denying that The Taming of the Shrew is patriarchy at its worst. Shakespeare presents to the audience Katherina – an intelligent, highly stubborn woman who is willing to challenge the sexist patriarchal ideologies of the 16th century. She is subjected to many things like verbal abuse, injustice and double standards, which all resonate with the audience.Katherina doesn't fit into the social convention because she challenges the ‘proper' gender roles of the 16th century. We see Katherina challenging gender conventions when she protests against being treated like a commodity in terms of marriage which at the time was like a business or financial transaction supposed to benefit the families involved. Katherina makes it clear at the be ginning of the play that she does not wish to be married to someone merely because of her dowry, much to Bianca's despair.In Act 2 Scene 1 Baptista agrees for Petruchio to marry her. Katherina is very against the idea, twisting his words, insulting and even striking Petruchio. She is finally shocked to silence when even despite her best efforts to protest, Petruchio deceives Baptista in claiming that Katherina wants to be married to him and she â€Å"hung about my neck, and kiss on kiss She vied so fast†. Katherina also challenges gender roles in that she will willingly stand up for herself, which was very unlike any woman of the time.This did not help her case in being a ‘shrew' with a loud, ill-tempered personality and a â€Å"razor-sharp tongue†. We see this in Act 1 Scene 1 when Katherina is being openly insulted and abused by Bianca's suitors and refuses to step down and accept the fact she is being called a â€Å"devil† and a â€Å"wench†. She retaliates with speech that is witty and shreds the suitor's comments, however it was extremely out of the social practice for women. We find her challenging the roles of men and women relatable merely because of the age old contest of men verses women.Because of the very limited roles women held in this era we find that we begin to appreciate her actions in that she will stand up for what she believes is fair and right, even if it has her portrayed as an outcast. Katherina finds herself ill-equipped for the social mould of the era as she begins to make a mockery of the power struggles not only within marital relationships, but also within society. Once married, women essentially lost all legal rights and their own identity.This is why Petruchio refers to Katherina as his â€Å"goods† and his â€Å"chattels† after their marriage ceremony (Act 3 Scene 2). Katherina hates the idea of not even being able to speak her mind because of her limited power in her marriage. She says in Act 4 Scene 3 that her heart â€Å"will break† if she is silenced and unable to express her frustration about her lack of power and control over even her own wardrobe. The play forces the audience to question their assumptions and attitudes about the power dynamics particularly in romantic couples, but also with friends and relatives.We can relate to Katherina not wanting to be treated like a commodity or be stripped of her own identity and values because every one of us have felt pressure to conform to somebody else's values. Whether it be at school, home or in a romantic relationship, phrases such as â€Å"be a good girl† or â€Å"be a man† reverberates with us all and this is what Katherina attempts to overthrow in her relationship with Petruchio. Katherina is forced to deal with injustice, when she is judged and treated with unfairness, as a result of her inability to conform to social and gender conventions.The main object of Petruchio marrying Kat herina was so that he could have the challenge of ‘taming' her. This to the modern audience seems manipulative – as if Katherina is more like an animal needing to be tamed. As a modern audience we have become far more sensitive to social injustices, and so as we witness the abusive behaviour and misogynistic attitudes towards Katherina we begin to feel almost sympathetic for her misunderstood actions and feelings. It is unfair that the only way Katherina could achieve domestic tranquillity was to conform to how Petruchio wanted her to be.She is never given any choice, pretending that the sun is really the â€Å"moon† and moreover that an old man is really a â€Å"budding virgin† just to make Petruchio happy (Act 4 Scene 5). It is clear that as soon as we meet the Minola family that Baptista is clearly more favourable towards Bianca. In Act 1 Scene 1, Baptista asks Bianca to go inside with him and practice her music and books, he disregards Katherina saying â€Å"Katherina, you may stay. For I have more to commune with Bianca†. It is also in this scene that even though Katherina speaks just three times, we hear more about her than from her .This speaks of the judgemental and misunderstood nature that she is subjected to. This fascinates us because as she struggles to overcome this treatment, it becomes very relatable to the audience. The concept of fairness has become, to nearly all of us, a given right. For the characters in The Taming of the Shrew to willingly let fairness be blatantly ignored, becomes a fascinating idea to the modern day audience. Even though fairness has become a right, we have all been put into situations where fairness hasn't always been practised, and so Katherina's plight becomes relatable.Audiences continue to be fascinated with Katherina's character because of the struggles that she faces with not fitting into a very concise, social mould. The Taming of the Shrew's audience in the 16th century was one that was heavily concerned with the concepts of marriage, and so it is only natural that Shakespeare creates a character that challenges all the concepts tied to marriage entirely. Katherina takes things head on when she not only tests the boundaries of the limited roles and expectations of a female, but also won't accept the distinct power roles of a man and woman in a relationship.The play celebrates the quick-wit and strong mind of Katherina, even whilst revelling in her humiliation and unfair treatment. Whilst the social conventions have changed since the 16th century, they are still very apparent in our society, and there will always be those who test and rebuke those widely held standards. One point that is worth considering is whether or not our conventions are shaping our society for advancement, or worse for regression.

Free the Research! Make Academic Journals Accessible toAll Recently, Laura McKenna, reporter for the Atlantic, wrote about her frustrations in trying to find scholarly articles without the access afforded to people with university affiliations. If you do not possess a college identification card, the hundreds of thousands of full-text articles from databases like JSTOR are either very expensive or inaccessible (McKenna shelled out $38 for a single twelve-page article, but also found that a great many articles were not available, period, to non-academics.) Why is this so and why does it cost so much? As McKenna points out, the researcher receives no royalties. (As an academic myself, I find that particularly disgruntling.) In her investigation, the reporter found that the answer lies within the antiquated system of academic publishing. Here is how that very old, very slow, ball rolls: Research takes several years. The academic (usually) receives grants and time off.   The article is then submitted to a journal. The actual journals are published in-house, on the campuses. They stay there because it brings the university acclaim. Journals are edited by faculty members, who often get a small stipend and a little time off to do this extra work. The article then goes to an editor, who then passes it on to other faculty with experience in the articles subject matter. The reviewers put in their two-cents. Article is then returned to the author for revisions. Editor submits that article, with a bunch of others, to a for-profit publisher. That publisher sells the rights to an academic search engine, like JSTOR. The publisher pays nothing to either the writer or editor. JSTOR digitizes the material and sells the content back to the university libraries. The publisher needs to get its money back. It charges a LOT to university libraries to subscribe to its service. It costs some libraries 65% of their total budget.   McKenna succinctly points out the insanity of this system: Step back and think about this picture. Universities that created this academic content for free must pay to read it. Step back even further. The publicwhich has indirectly funded this research with federal and state taxes that support our higher education systemhas virtually no access to this material, since neighborhood libraries cannot afford to pay those subscription costs. Newspapers and think tanks, which could help extend research into the public sphere, are denied free access to the material. Faculty members are rightly bitter that their years of work reaches an audience of a handful, while every year, 150 million attempts to read JSTOR content are denied every year. It seems to me (and to McKenna) that the requirement for print versions of articles is nonsensical. Without the print requirement, there is NO NEED for a third party.

Difference in Gothic and Romanesque architecture Essay Essays

Difference in Gothic and Romanesque architecture Essay Essays Difference in Gothic and Romanesque architecture Essay Paper Difference in Gothic and Romanesque architecture Essay Paper Different Architecture of Romanesque and Gothic Inspired Buildings There have been legion pilgrims journeies made across France and Spain. each one merely every bit alone as the one before it. Along these paths there are an unmeasurable figure of brilliant churches and temples each with their ain history. architecture and art work. doing them really typical. Time and topographic point are of import influences of the design of these churches and temples when they were built ; this means that we have encountered tonss of distinguishable architectural types along our pilgrims journeies. I will analyze every bit good as comparison the similarities and differences of two types of architecture from the center ages called Romanesque and Gothic. Romanesque and Gothic architecture differ in many ways from how the exterior expressions to the temper on the interior to the sculptures. arch types and the clearstory. The two architectural types are different because they were influenced by the dif ferent forces environing them at the clip. The periods in clip when these architectures were being defined played an of import function in the result. Romanesque architecture started being used in the sixth century and finally evolved into Gothic architecture in the twelfth century which lasted until the sixteenth century. 1 We can see clear development of the distinguishable characteristics of Romanesque architecture morphing into Gothic architecture. During the twelfth century there are edifices incorporating characteristics of both Romanesque and Gothic architecture. As the edifices would take old ages to finish. the initial phases of the edifice would be Romanesque and the ulterior parts would be Gothic. I will look closely at two churches while besides touching on other churches that we have discussed this semester and compare their characteristics. St Sernin in Toulouse. France and Notre Dame Cathedral in Chartres. France will stand for Romanesque and Gothic creditably. The church of St Sernin is the largest church in Toulouse. the 4th largest metropolis in France. and it is Romanesque architecture at its finest. Toulouse was one time portion of a part called Roman Gaul and the church was built during the clip of the Roman Empire. This is why we see Romanesque architecture throughout France and countries of Spain. The Notre Dame Cathedral in Chartres. France is considered to be one of the most of import Gothic edifices. non merely along the pilgrims journey paths but in the universe. Unlike Toulouse. Chartres is a bantam small state town nevertheless. Notre Dame Cathedral is celebrated for its beautiful architecture. alone sculptures and awe inspiring discoloration glass Windowss. The outside of Romanesque architecture was built more for map than beauty. We find most of this architecture embedded in palaces where defense mechan ism was imperative. While defense mechanism wasn’t as of import for the churches we can still see this manner bing in many Romanesque churches. â€Å"The walls of Romanesque edifices are frequently of monolithic thickness with few relatively little openings† . 2 Having midst walls and little Windowss. the palaces were about impenetrable nevertheless this meant the design of the churches were comparatively simplistic when compared to Gothic edifices. When we look at St Sernin we able to place these characteristics. There are legion Windowss around the church nevertheless as St Sernin is a instead big Church you would anticipate to see more Windowss with other manners of architecture. The forepart of St Sernin has one big unit of ammunition window but the remainder of this facing is chiefly rock with few comparatively little Windowss. When we compare this to Gothic architecture we can see a important difference. When Romanesque architecture evolved into Gothic architecture the arches were no longer merely for prolonging the weight. they became more visually appealing. Gothic architecture came to be because of â€Å"a a lone combination of bing technologies†¦ Those engineerings were the ogival or pointed arch. the ribbed vault. and the winging buttress† . 3 These new engineerings meant that the exterior walls could be thinner and have more Windowss as the weight of the roof and upper degrees were better distributed through clustered columns. Having lighter walls and more Windowss and gaps led to more cosmetic and visually arresting edifices considered to be plants of art. Notre Dame Cathedral is an impressive work of art which uses all the new engineerings in exposing one of the finest illustrations of Gothic architecture. The frontage of the cathedral is high and good decorated. There is a brilliant unit of ammunition window which is the centre piece of the face which is surrounded by countless pointed arch Windowss designed to back up the weight. Unlike the church of St Sernin where most of the forepart wall was rock. Notre Dame’s forepart wall consists largely of Windowss. These exterior characteristics had a important imp act on the interior feel and temper of the edifices. The sum of light Lashkar-e-Taiba in by the two comparative architectural types has a batch to make with the feel and temper of the inside. When come ining different edifices one â€Å"can experience the difference between the [ two types of ] architecture† . 4 When it comes to the Romanesque manner of St Sernin. really small visible radiation is able to perforate the midst walls with small gaps which makes the interior temper experience dark and glooming. When you compare that to the Gothic Notre Dame. with its legion Windowss it has a wholly different feel. Alternatively of experiencing dark and gloomy like St Sernin. Notre Dame’s inside has a much lighter and a more inviting mood. ] Another specifying characteristic of Gothic architecture is one of the new engineerings. the pointed or ogival arches. This new manner of transporting the weight was radical as costs could be cut by holding more glass and less rock work. Structural â€Å"use of the pointed arch gave a greater flexibleness to architectural signifier. it besides gave Gothic architecture a really different ocular character to Romanesque† . 5 These arches meant the ceiling could be made higher than before symbolizing an aspiration for Eden. All Gothic gaps such as Windowss. room accesss and galleries are made with pointed arches. The church at St Sernin is no exclusion to this regulation. Looking at the exterior of the edifice all you can see is pointed condescending doors and Windowss. It is the same one time you have entered the edifice. pointed archways running down both sides of church. Compared to Gothic architecture. Romanesque architecture was an out-of-date technique when it came to effici ency. Romanesque design wasn’t as advanced. alternatively of utilizing efficient pointed arches like Gothic designs ; rounded or semi circle arches were used for their arches. This is more efficient at keeping weight than a square room access but non every bit efficient as a pointed arch. To get the better of this failing of the rounded arches â€Å"instead of a individual unit of ammunition arch of rock to cross an opening†¦ [ they use ] countless arches† . 6 This manner the weight burden is spread over legion arches alternatively of a individual arch. When we look at the church in St Sernin the room accesss and Windowss are all rounded. The chief entryway has two big rounded room accesss. when we look closely we can see it isn’t a like the other arches. to transport the weight they have made the arch wider than the wall coming out a few pess. When we go inside we can see that on top of the rows of columns on the inside there are rounded arches. even the r oof is a rounded arch which is supported by moulded arches. Sculpture work that exists on the interior and outside of churches had two intents. Intricate sculpture works on the churches were visually appealing doing them more attractive to pilgrims and tourers and it was besides a manner of storytelling that was guaranteed to last every bit long as the church. Romanesque sculptures evolved over the old ages holding three distinguishable periods. A crude period. the 2nd period was marked by churrigueresque hyperbole and the concluding refinement and assimilative period. 7 This manner of sculpture work frequently depicts scenes of mundane life including both people and animate beings. While the scenes of the sculptures seldom altered. how they were depicted was. In the 2nd period â€Å" [ g ] rotesque figures of work forces and animate beings. and designs derived from vegetable kingdom†8 were common. As we move into the 3rd period word pictures are more realistic. At St Sernin there is an copiousness of Romanesque sculptures carved into the south portal. It is an early piece of Romanesque sculpture work as the topics of the art work are all regular in visual aspect. Over the south portal is a scene of Christ with the 12 apostles below looking up at him. This was a common adequate word picture of Christ in Romanesque design. a really similar piece had been carved on a different church carved twelve old ages earlier. The terminal of the Romanesque period flowed swimmingly into the new Gothic manner of sculpture work. While it continued the â€Å"tradition of Romanesque sculpture. but it changed in its iconography †¦ be givening towards a didactic representation of the most of import individuals and scenes in the Holy Scripture† . 9 Other common subjects are the 12 months and the marks of the zodiac. angels and saints. Gothic architecture took the already bing Romanesque architecture and channelled this into a more comprehensive and deliberate work of art with the ability to touch any single that gazes upon her art and for persons who understand Gothic sculpture have a deeper grasp. The facade at Notre Dame Cathedral has three magnificent room accesss. and above the Centre room access is a great word picture of Christ created utilizing a Gothic sculpture manner. Jesus is standing surrounded by an bird of Jove. bull. king of beasts and a winged adult male. Visitors are able to bask this work for its quality although those who understand the piece realise that the bird of Jove represents Saint John. the bull represents Saint Luke. the king of beasts represents Saint Mark and the winged adult male represents Saint Matthew. Gothic and Romanesque architecture dominated the in-between ages used to make brilliant churches. temples and palaces considered to be plants of art. Romanesque architecture evolved into Gothic architecture during the twelfth century. While these two types of architecture sometimes overlapped during the transitional period. Gothic and Romanesque architecture are like chalk and cheese when you examine themclosely. From the inventiveness of the design. the temper and feel of the inside. the ocular consequence of the outside and the beautiful sculpture work. Gothic architectures used all of the available engineerings available to them. so they were able to make constructions that Romanesque architectures could merely woolgather of. These new design methods meant that the interior temper has besides morphed ; Romanesque architecture had a moist and dark temper which evolved into the bright and ask foring Gothic architecture. Sculptures went from being monstrous figures in Romanesque architecture to a more defined and meaningful work of art in Gothic architecture. These two different manners of architecture may be different nevertheless they are still both rather capable of animating persons which means that they will be a finish for pilgrims and tourers for the old ages to come.
