Web Server Application Attacks Assignment Example | Topics and Well Written Essays - 750 words

Web Server Application Attacks - Assignment Example This keeps the web application safe from malicious user inputs. Session Security Vulnerabilities. When session ID’s are sequential and persistent or when session tokens are not protected, one user may access another user’s data through assuming the other user’s identity. To mitigate this, session ID’s must be random and must expire when a user logs out of the session. Session tokens must be protected and invalidated when the user logs out. 3. Authentication Vulnerabilities When server does not authenticate a user before giving him access to a web application, he may gain access to sensitive information and mishandle it. To counter this problem, the user must apply authentication rules like HTTPS. User must ask for authentication after specified intervals. Access control must also be implemented. Part 2 Protecting Web Servers from Denial of Service (DoS) Attacks Denial of Service (DoS) attacks prevent web servers from serving websites to genuine users. These attacks are, mostly, targeted toward professional websites run by political or other important organizations, in order to hinder their web presence to their clients and users (AppliCure Technologies, 2013). However, small businesses are also not free of such threats. The websites cease to operate partially or fully. A DoS intrusion detection architectural design is a must-use in order to prevent such attacks. Mell, Marks & McLarnon (2000) have discussed this architecture in their article, in which intrusion detection software (IDS) components are hidden from the attacker. In case the attack is successful, IDS components are shifted from the attacked host to functional host, where they counter with the attack successfully. This is done by by using mobile agent technology and network topology features. The communication bet ween various IDS components is also restricted (Mell, Marks & McLarnon, 2000). Part 3 a. Basic motivation behind the attack on the Justice Department, as hackers themselves stated, was that they wanted to â€Å"release government data† (Zabarenko, 2013, para.1). They were also outraged over the death of the late computer prodigy Aaron Swartz, who had committed suicide on January 11 this year. He had been facing trial for stealing millions of online JSTOR articles. b. I would have used Ping of Death, as it is a dummy ICMP packet receiving fragments of ping, and resembles the real packet. It becomes too big for the buffer once reassembled, which starts overflowing, and thus, the system hangs (Canavan, 2001, p.39). I would use this because there are freely available source code examples on the internet for Unix to create large ping packets. It is very easy to ditch the user through fake ping packet. c. Web server application attacks are not as easy as they may seem, because ther e are many different kinds of anti-virus softwares, intrusion detection softwares, and user input detection and encoding softwares that are being implemented nowadays. These special softwares make it very hard for the attackers to succeed in their attacks. Part 4 To maintain a secure web presence, Federal government organizations need to maintain special mitigation strategies. Designing an information security policy is the first step towards the implementation of information security (Danchev 3). A security policy acts as a centralized crucial document that will help in eliminating the risk of security breaches by securing the confidential information stores from getting disclosed to unauthorized persons. It defines the importance of a

Career aspiration Essay Example | Topics and Well Written Essays - 750 words

Career aspiration - Essay Example My interest is in aviation engineering. Aviation engineers end up airport executives and professional pilots although this branch is also related to airspace development, designing the airport, navigation technologies, and so on. Airspace development is related to planning and designing the airspace. And it is extremely important that it is done in a proper manner in order that military operations are not affected and also so for the easy navigation of commercial airlines. Then there is airport design, which is again important due to several reasons, one being that the design needs to be in accordance with global environmental standards. Aviation engineers in the manufacturing field are generally paid between $17,500 and $54,500 (AvScholars). Their responsibility is toward production; ranging from developing and selecting manufacturing ways to overseeing everyday tasks taking place on the factory floor. They have to intensely research regarding designing, projecting, production and maintenance technologies and functions of various kinds of vehicles that move in sky or space. Also, there is a requirement of manufacturing better aircrafts – lighter and faster, those that comply with the environmental rules and those that do not make too much sound. All this comes under the work of aviation engineers as they are responsible for the design and manufacture of aircrafts. They have to decide which production system will prove to be better for manufacturing in terms of cost. They have to conduct experiments that help in determining the performance properties of the air vehicle that has been designed and this is done through analytical skills. A person definitely needs a proper engineering degree to pursue aviation engineering for which purpose it is extremely necessary that there are highly qualified institutions that cater to the interested people. An undergraduate education in this field is of four years and the graduating students receive a

Soto Essay Example | Topics and Well Written Essays - 750 words

Soto - Essay Example Soto exhibits several strong purposes in writing this essay. The first thing that the reader will notice is that this author writes to entertain. The reader can visualize the boy in the story trying to find something to do other than watch ‘the perfect family’ on television all summer. His interactions with others throughout the story, while carrying an underlying tone we will analyze in a moment, are written in a narrative format that is easy to follow along. Whoever reads the story can feel a part of the boy’s life and truly visualize what he spends his summer days doing. When he encounters Mrs. Moore in his effort to do some work at her house, she exclaims â€Å"It’s summer, and there ain’t no leaves† (Soto 24). This makes us all remember the days of our youth and our good-natured encounters with the neighbors. A subsequent, more serious purpose to this essay lies in the life of the boy and his siblings. Soto appears to be asking the reader to empathize with the characters in the story. Adults all around them seem to be communicating that, because of their Hispanic heritage, they can only go so far up the ladder of success in society. So, they spend their days watching the perfect ‘white’ family on television and wishing, almost, that they had been born into a different family, or at least at a different time. This is a social message. Soto is effectively asking his audience to imagine being a child who feels others around him are superior to him simply because of their race. He also is asking the reader to visualize being a child and discovering that nearly every adult in your life supports the notion that you are stuck where you are and cannot advance. It is certainly not a ‘pretty picture’, but it is certainly a message that certainly gives the reader pause to reflect and consider. Soto was effective in pointing the readers, in an entertaining fashion, towards a serious social problem faci ng the country. He takes issue with boys and girls who are told their dreams cannot come true even before they reach the middle of adolescence. The boy’s two siblings seem to already have bought into this notion. His brother, in essence, spends his days playing around in the ditch and really desires to do nothing else. Sensing that there is more to life, the boy begins to strike out on his own and try to make something of himself. Sure, this is just a story, but the message and purpose is clear. Soto really desires to use this essay to point towards this perceived social injustice and he challenges society to take action. To this end, the author is effective. One of Soto’s ideas during this essay is that adults perpetuate this feeling in minority children that they are destined to a life that is inferior to others. He demonstrates this with the boy’s mother. Early in the story, the narrator’s mother tells him â€Å"Boy, are you a crazy Mexican. Where did you get the idea that people eat turtles?† (Soto 23). The implication of the mother throughout is clear. While she certainly seems to love her children, she believes that, since they are Mexican, they cannot be like the ‘white children’ they see on television. Sure, you want your children to be proud of their race. Upon analyzing this essay and its purpose, however, it is

Haematology Essay Example | Topics and Well Written Essays - 500 words

Haematology - Essay Example Once these mechanisms fail and the cells reproduce without control, cancers are the resultant to a deadly organism as a whole. (Mutimer, 2000, p. 59) Proliferation can be understood by two characteristics 1) Cell growth and 2) Cell division. Both occur as a result by increment in number of cells. Proliferation, as appropriated within the study of cancer, refers to an autonomous process of growth and spread, internally driven but externally controlled. Danger arises when the controls fail and the natural proliferation of cells produces excessive reproduction. Young, immature (unspecialised) cells take on individual characteristics and reach their mature (specialised) form and function". (Cancer2006) Dr. Anderson describes that "correct differentiation of embryonic cells is essential in order to structure the cells associated with the complex environment of embryo. Failing to replicate the full range of normal developmental signals is likely to have disastrous consequences. Providing some but not all of the factors required for embryonic stem cell differentiation could readily generate cells that appear to be normal (based on the limited knowledge scientists have of what constitutes a "normal cell type") but are in fact quite abnormal". (Condic, 2002) Maureen (2002) in her article further talks about differentiation in terms of differentiated cells that transplant incompletely while runni

Pain in unresponsive patients Essay Example | Topics and Well Written Essays - 2500 words

Pain in unresponsive patients - Essay Example A contributing factor for this could be that the various pain scales available for noncommunicative patients generally are subjective and, therefore, lacking in inter-rater reliability. Besides, research in pain assessment tools has not been adequate. The major aims of this study are (1) to compare the Numerical Rating Scale and the Behavioral Pain Scale for measuring pain in unresponsive patients, and Pain is an important problem in critical care and accurate assessment of pain in the unresponsive patient is indeed a challenge. The unresponsive patients include pediatric, trauma, surgery, cancer, and critically ill, end-of- life cases. The attending nurses are generally accountable for pain management in the patient. It is estimated that critically ill patients dying in the ICU account for nearly 20% of the hospital deaths (Rocker & Curtis, 2003). Hence, nursing care decisions made at the end of life are crucial for the comfort of the patient. Palliative care has been defined by the World Health Organization as "the total care of patients and families whose disease is not responsive to curative treatment" (WHO, 1990, p.11). Assessment and management of pain in the palliative care is a very difficult process especially in the case of a non-verbal patient (Gambrell, 2005). Health-care providers play an active role in managing pain and providing comfort to such patients. But unmitig ated pain in the absence of adequate use of analgesics and sedatives can lead to enhanced morbidity and mortality in patients in the ICU (Ahlers et al., 2008). The tools available for pain assessment in noncommunicative patients are mostly subjective which is a great drawback. Ideally, an objective tool for quantification of pain intensity capable of providing a quick feedback would be needed to provide comfort to the unresponsive patient (Gambrell, 2005). Critically ill patients show a variety of hormonal changes and neurogenic blockade and analgesia with local anaesthetics can prevent
