Prevention to Threats and Attacks on Computer Network Assignment

Prevention to Threats and Attacks on Computer Network - Assignment Example An IDS based signature monitors the network for packets and compares them against signatures or known threats in the database. Tremendous increase of services and information that is sensitive on networks has made security very important. However, the more network technologies have developed, the more network attacks have increased in severity and numbers. Intrusion detection systems (IDS) can effectively provide network security by preventing, detecting, and possibly fighting attacks. Such systems monitor sources of activities while employing various security techniques. Therefore, they ought to be precise in quickly defining attacks, in training and generating very few positives. Network Intrusion Detection Systems (NIDS) monitor networks for intrusions or attacks, reporting them to the administrator for necessary activity. A NIDS server that is large enough may be created on a backbone of network, to check and asses all traffic; or other smaller systems may be created to check or asses traffic for a specific server, gateway, switch, or router. The computing environment is constantly evolving and this demands Intrusion detection products to aid in managing attacks in this changing environment. Threats can be individuals or groups that wish to compromise a computer system such as disgruntled employees, rival companies or even foreign governments and their attacks can be devastating on the network systems. Intrusion attacks are those where an attacker enters ones network to read, damage, and/or steal data (Albitz 1992). These attacks can be divided into two: Port scans: A scanner is a program that probes a system remotely to establish which TCP/UPD ports are open and if they are subject to attacks. It identifies a computer at risk within the network, find the services that are installed on the computer, and show weaknesses in operation (Hudson KURT and Stewart Michael.

The Contribution Of Feminist Criticism To Opera Studies Essay

The Contribution Of Feminist Criticism To Opera Studies - Essay Example In order to defend the position of a woman and stop discrimination, feminism penetrates all the spheres of life. As the old values of the society have been formed for a long time and are reflected in the works of art, it became necessary for the strugglers for human rights to make feminist movement influence the sphere of art. Old plots of classical art creations are very popular today and widely used by producers for their performances. However, feminists claim that many of these plots should be modified. The trouble is that they plunge us into the past values and traditions feminists did their best to change. As the plots are too old, the representation of women is usually too discriminative and reminds men about their dominance in the past. Under such influence the efforts of feminists risk to come to nothing, thus they consider it necessary to impose their effect on the sphere of the modern art. The given paper will provide the overview of the feminist influence in the sphere of mass media and demonstrate how the modern opera is affected by the feminist movement. The main argument of feminists is the â€Å"male gaze† that can be traced in modern performances. Notwithstanding that feministic mood penetrated many fields, the sphere of film-making remained almost unchanged. It keeps using motives, which are considered to be classical, in spite of the fact that they were formed in the patriarchal society. A woman continues playing secondary role. Boetticher explains: "what counts is what the heroine provokes, or rather what she represents. She is the one, or rather the love or fear she inspires in the hero, or else the concern he feels for her, who makes him act the way he does. In herself the woman has not the slightest importance."1 If to trace the literary works on the topic, it becomes clear that the problem was started to be considered by the strugglers for women’s rights already in 1970s. The work by Mulvey titled "Visual Pleasure and Narrat ive Cinema" discussed the secondary role and discrimination of women. The author states: "in their traditional exhibitionist role women are simultaneously looked at and displayed, with their appearance coded for strong visual and erotic impact so that they can be said to connote to-be-looked-at-ness," and as a result contends that in film a woman is the "bearer of meaning, not maker of meaning.†2 The author draws the readers’ attention to the theory of Lacan that explains how the performances contributes to gender discrimination by depicting women as objects for sexual exploitation. Mulvey emphasizes the importance of re-consideration of the plots used to make performances. She states that the radical changes in the film-making structure are crucial as it is the only way to eliminate gender discriminative motives from modern performances. The issues of women discrimination in opera was discussed in the book by Catherine Clement. The feministic work â€Å"Opera: The und oing of Women† were created at the end of 1970’s. The author strongly believes that in opera women are oppressed and men dominate over them. She underlines that women in opera are portrayed as victims, who cannot express their own feelings and who sacrifice their lives for their beloved men. The life of these women in most situations has a tragic end. Really, it is possible to trace that most of the female protagonists appear in difficult circumstances and they are always unhappy and dissatisfied. In order to prove that it is enough to overview the most famous plots that are depicted in opera. The main heroine of â€Å"Tosca† Floria has committed suicide after she got to know about the execution of her beloved. The opera â€Å"Madam Butterfly† is rather popular, but if to consider it from critical point of view, it is plot is
