Conclusion and Recommendation Essay Example for Free

Conclusion and Recommendation Essay Moral implies conformity to established sanctioned codes or accepted notions of right and wrong or the basic moral values of a community. Ethical may suggest the involvement of more difficult or subtle questions of rightness, fairness or equity. While legal is sanctioned by law or in conformity with the law especially as it is written or administered by the courts. (Merriam-Webster) Relating the results of the gathered data of the study about the dog eating practice in Baguio City and La Trinidad to morality and the legal aspect of which, the researchers were able to come up with conclusions and recommendations. Regarding the moral aspect of the practice of dog eating, the study revealed that it is accepted to consume dog meat. The prevalent reasons are that dogs are basically meat for food and dogs are used in the cultural and ritual practice. Dogs are made as offerings and were eaten for health reasons. Law enforcers admitted that dog meat consumption is a right as guaranteed by our constitution. They too believed that consumption of dog meat will continue. However, trading dog meat is prohibited with the advent of the Anti Rabies Act and the Animal Welfare Act. In legal parlance, as stated above that dog eating is presumed to be legal for the the act of trading dog meat is prohibited. Even the constitution entitles everyone to our basic needs which include food, shelter and clothing. Eating dog meat is then legal for the fact that it is considered as food. But with special laws being passed which condemned the trading of dogs for consumption purposes made the eating practice seemingly illegal as well. Knowing now that the trading and not the eating practice is illegal, the researchers recommend a deeper investigation on the source of dog meat supplied in the city and the capital town. Our law enforcers like the National Bureau of Investigation and the Philippine National Police should coordinate to be able to put to an end the trade of dogs. Cases filed against trading of dog meat in courts were dismissed due to the open interpretation of the law. The researchers would therefore recommend for our lawmakers to revisit the Anti Rabies Act and the Animal Welfare Act. For our lawmakers to clearly define animal cruelty and other silent parts of the law which are open for individual interpretations.

Automated Protocol to Restrict Password Guessing Attacks

Automated Protocol to Restrict Password Guessing Attacks ABSTRACT Password login services are now widespread and ever increasing. Attacks that take place on password-only remote login services are brute force and dictionary attack. Providing convenient login for legitimate user.In the proposed system we use Password Guessing Resistant Protocol (PGRP) which improves more security by restricting the number of attempts. PGRP allows a high number of failed attempts from known machines. PGRP uses either cookies or IP addresses, or both for tracking legitimate users. Tracking users through their IP addresses also allows PGRP to increase the number of ATTs for password guessing attacks and meanwhile to decrease the number of ATTs for legitimate login attempts. Key Words – Online password guessing attacks, brute force attacks, password dictionary, ATTs. 1. INTRODUCTION: Online password guessing attacks are the most commonly observed against web applications SSH logins. SANS report observed that password guessing attack is the top cyber security risk. SSH servers that doesn’t allow some standard password authentication suffer the guessing attacks. Online attacks have some disadvantages compared to offline attacks i.e., the attacking machines must use an effective interactive protocol which allows a easier detection of malicious attacks.Malicious attackers try only limited no. of password guesses from a single machine being that account is being locked or before being challenged to answer an ATT. An attacker will employ a large number of machines to avoid locking out. Generally users choose weak passwords. As malicious attackers control large bot nets online attacks became much easier.Restricting the no. of failed trails without ATT’s to a very small number is the effective defense system that can be used against automated online passw ord guessing attacks. Also limiting automated programs(or bots) used by attackers for password guesses for a targeted account, even many different machine from a bot net are used. This method inconveniences offers a legitimate user to answer an ATT on next login attempt after the malicious attackers guesses. Other techniques deployed in practice includes: Even though from a given machine when a certain number of failed attempts occur,it allows login attempts without ATTs from a different machine. After a certain time-out period, it allows more attempts without ATTs and also time-limited account lockinMany existing techniques proposals involve ATT’s, assuming that the challenges provided by the ATTs are difficult for botseasy for people(legitimate users). Users are increasing disliking ATTs and feels it as an unnecessary extra step. Successful attacks are being made which break ATTs without human solvers. ATTs that are to be more difficult.As a consequence, present-day ATTs are becoming more difficult for human users. Therefore, we focus more on reducing user inconvenience by challenging users with fewer ATTs and at the same time subjecting bot logins to more ATT’s, to drive up economic cost to attackers.Two well-known proposals using ATTs to limit online guessing attacks are Pinkas and Sander (PS protocol) and Van Oorsc hot and Stubblebine (VS protocol). The PS proposal reduces the ATTs. The VS proposal reduces this but a significant cost to usability.. The PGRP is being developed by using both PS VS proposals. On the other side, PGRP allows high number of failed attempts from known machines without answering any ATTs. Known machines are defined as those from which successful login has occurred over a fixed time period. These known machines are identified by their IP addresses which are saved on the login server as white list or else in the cookies stored on client. Both the white listed IP address and client cookie expire after a time-period. In both graphical user interface(e.g., browser-based logins) character-based interface(e.g.,SSH logins) PGRP can be accommodated). Both PS and VS proposals, requires the use of browser cookies. PGRP uses either cookies or IP address or both for tracking legitimate users. PGRP increases the number of ATTs for password guessing by tracking users through their IP address also to decrease the number of ATTs for legitimate login attempts.In recent years, the trend of logging in to online account through multiple personal devices (e.g., PC, laptop’s,smartphones ) is growing. When used from home environment, these devices often share a single IP address which makes IP-based history tracking more user friendly than cookies. 2. Related work: From the early days of the internet the online password guessing attacks have been known to everyone. Account locking is a mechanism which prevents a malicious attacker from multiple passwords particular username. Although account locking is temporary remedy, an attacker can mount a DOS (denial of service) in some amount of time for a particular username can be done by delaying server response after receiving user credentials, whether the password is correct or incorrect. However, for an attacker with access to a botnet, this above mechanism is ineffective. Prevention techniques that depend on requesting the user machine to perform extra computations before replying to the entered credentials are not effective with such adversaries. To prevent the automated programs (brute force dictionary attacks) ATT challenges are used in some protocols.PS presented a login protocol which challenges ATTs to protect against online password guessing attacks. PS protocol reduces the number of ATTs that authorized users must correctly answer, so that a user with a valid browser cookie will be rarely asked to answer an ATT. A deterministic function AskATT() of the entered user credentials is used to decide whether to ask the user an ATT or not. To improve the security features of the PS protocol, Van Oorschot stubblebine defined a modified protocol in which ATTs are always required, once the no. of failed login attempts for a particular username exceeds a threshold. For both PS and VS protocols, the function AskATT() requires a careful design, because the ‘known function attack’ of poor design of this function AskATT() makes the login protocol vulnerable to attacks and also ‘change password attack’. Because of these attacks, the authors proposed a secure non-deterministic keyed hash function as AskATT() so that each username is associated with one key that changes whenever the corresponding password is changed. This proposed function requires extra server-side storage per username atleast one cryptographic hash operation per login attempt. 2.2 Functions PGRP uses the following functions. They are 1.Read Credential. It shows a login prompt to the user and it returns the entered user name and password and also the cookie received from the user’s browser. 2. Login Correct If the provided user name-password is valid, the function return true otherwise it returns false. 3. Grant Access This function sends the cookies to the user’s browser and then gives the permission to access the specified user account. 4. Message It displays the text message. 5. ATT Challenge This function challenges the user with an ATT. If the answer is correct, it returns â€Å"pass† otherwise, it returns â€Å"fails† 7. Valid This function checks the validity of the cookie and it is considered invalid in the following cases: The cookie username doesn’t match with the login username. The expired time of the cookie. The cookie counter is equal to or greater than K1. This function returns true only when a valid cookie is received. 3. Cookies versus Source IP addresses PGRP keeps track of user machines from which successful logins have been initiated previously. If the login server offers a web-based interface, for this purpose choose a browser cookies as a good choice. The login server unable to identify the user in all cases, if the user uses multiple browser or more than one OS on the same machine. Cookies may also be deleted by users, or automatically enabled by the most modern browsers.Cookie theft(eg., through session hijacking)might enable an adversary to impersonate a user who has been successfully authenticated in the past. In addition cookies requires a browser interface.A user machine can be identified by the sourceIP address. To trace users depending on sourceIP address may result in inaccurate identification. This can be done because of various reasons including. 1) The same machine might be assigned different IP addresses. 2) A group of machines might be represented by a small number or a single internet-addressable IP address if NAT mechanism is in place.Drawbacks of identifying a user by means of either a browser cookie or a source IP address include: 3) Failing to identify a machine from which the user has authenticated successfully in the past. 4) Wrongly identifying a machine the user has not authenticated before. Case 1) Decreases usability since the user might be asked to answer an ATT challenge for both correct and incorrect login credentials. Case 2) Affects security since some users/attackers may not be asked to answer an ATT challenge even though they have not logged in successfully from those machines in the past.However, the probability of launching a dictionary or brute force attack from these machines appears to be low. Therefore, we choose to use both browser cookies and source IP address in PGRP to minimize user inconvenience during login process. 3.1. Decision function for requesting ATT’s: The decision to challenge the user with an ATT depends on two factors: 1) Whether the user has authenticated successfully from the machine previously. 2) The total number of failed login attempts for a specified useraccount Fig. 2.Secure but inconvenient login protocol 3.4.1Username-Password Pair Is Valid After entering a correct username-password pair. In the following cases the user will not be asked to answer an ATT challenge. 1. A valid cookie is received from the user machine and the number of failed login attempts from the user machines IP address for that username, FS[srcIP,un], is less than k1 over a time period determined by t3. 2. The user machine’s IP address is in the whitelist W and the number of failed login attempts from this IP address for that username, FS[srcIP,un], is less than k1 over a time period determined by t3. 3.The number of failed login attempts from any ,machine for that username, FT[un], is below a threshold k2 over a time period determined by t2 3.4.2Username-Password Pair Is Invalid After entering a incorrect username-password pair. In the following cases the user will not be asked to answer an ATT challenge. A valid cookie is received from the user machine and the number of failed login attempts from the user machines IP address for that username, FS[srcIP,un], is less than k1 over a time period determined by t3. The user machine’s IP address is in the whitelist W and the number of failed login attempts from this IP address for that username, FS[srcIP,un], is less than k1 over a time period determined by t3. The username is valid and the number of failed login attempts for that username, FT[un], is below a threshold k2 over a time period determined by t2. 4 System Resources No list’s are maintained in the PS protocol because of this there is no extra memory overhead on the login server. In VS protocol only FT is maintained. In PGRP, three tables must be maintained. First, the white list, W is expected to grow linearly with the number of user’s. W contains a list of{source IP address, username}pairs that have been successfully authenticated in the last t1 units of time. Second, the number of entries in FT increase by one whenever a remote host makes a failed login attempt using a valid user name, if entry is added to FS only when a valid{user name, password} pair is provided from an IP address not used before for this user name. Therefore, the number of entries in FS is proportional to the number of IP addresses legitimate users successfully authenticated from. 4.1  Background On Previous ATT Based Protocols Pinkas and Sander introduced the topic based upon a strawman login protocol that requires answering an ATT challenge first before entering the {user name, password}pair. If the user falling to answer the ATT correctly prevents the user from proceeding further. This protocol requires the adversary to pass an ATT challenge for each password guessing attempt. Simple protocol is effective against online dictionary attacks assuming that the used ATT’s are secure, legitimate users must also pass an ATT challenge for every login attempt. Therefore, this protocol affects user convenience and requires the login server to generate an ATT challenge for every login attempt. Pinkas and Sander proposed a new protocol that reduces the number of ATT’s for legitimate user’s are required to pass. This protocol stores a browser cookie on the machine of users who had previously logged in successfully. Once the user requests the login server URL, the user’s browser sense the cookie back to the server. The protocol then requests the user to enter a {user name, password} pair. If the pair is correct and a valid cookie is received from the browser then the protocol gives permission to access the account. If the pair is correct but no valid cookie is received, then an ATT challenge must be answered before account access is granted. Otherwise, if the pair is incorrect then according to a function AskATT(), an ATT challenge might be required before informing the user that the pair is incorrect. With this protocol, legitimate user must passATT’s in the following cases:1) When the user logs in from a machine for the first time. 2) When the user’s pair is incorrect and AskATT() triggers an ATT. For each password guessing attempt an automated program needs to correctly answer ATT except in one case i.e.,when the {username, password} pair is incorrect and a function AskATT() didn’t request an ATT. Van oorschot and stubblebine proposed modifications to the previous protocol which stores failed login’s per username to impose ATT challenges after exceeding a configurable threshold of failures. Hence, for an incorrect {username, password}pair, the decision to request an ATT not only depends on the function AskATT() but also on the number of failed login attempts for the username.After entering correct credentials in the absence of a valid cookie, the user is asked whether the machine in use is trustworthy and if the user uses it regularly .The cookie is stored in the user’s machine only if the user responds yes to the question. This approach aims to reduce the possibility of cookie theft since a negative answer is expected if the user was from a public machin e .The user account is set be in non-owner mode for a specified time window when a login is successful without receiving a valid cookie from the user machine; otherwise the account is set to owner mode.

The Wessex Tales Essay -- miscellaneous

The Wessex Tales Explore Hardy’s portrayal of women in three of the stories studied. The Wessex tales was set in the nineteenth century; Thomas Hardy decided to write his stories and novels in the past, during the nineteenth century before he was born. Hardy got some of his ideas from his grand parents; he used to spend long evening next to the fire listening to his grand parents telling stories form the past. Thomas Hardy invented his own places He is highlighting the point that women around that time do not have a say in any thing. The expectations of women were that they had a lower profile At this time people lived in small communities so every one knew each other, so gossip got around the community. If any one did any thing wrong then they became a victim of there own community, and would become isolated. Thomas Hardy portrays Rhoda s being a social victim for having a child out of wedlock, although she is isolated it is ironic that Farmer Lodge is not, but he is still accepted as part of the community. This shows women are lower than men women are inferior to men. Farmer lodge does not acknowledge the fact that he has a son ‘Just the same as usual’ ‘ Took no notice of you’ ‘None’ Rhoda son is use to his dad ignoring him. All that Farmer Lodge has given Rhoda is a job, Rhoda works away from the rest of the workers because she has been discarded. Hardy describes Rhoda as ‘Fading women of thirty’She looks older than she actually is; it also...

The Advantages of Keeping pets :: Pets Animals

Would you like to live a happy and productive life? Then get pets! I must admit it is hard to believe that domesticated animals can promote mental and physical health, but many studies have shown that they can. People who own pets have been known to lead longer and happier lives than those without them. As we get older, we become less active. The more inactive we become, the higher our risk of death. We therefore need something in our lives to keep us busy so we don’t die prematurely, and a pet is just the thing to do it. This is probably because of the companionship, exercise, and responsibility that they provide. On the other hand, you must find a pet that is compatible with you or with your life style. Maintaining good mental health is crucial for living a normal life. Many psychiatrists have found that patients with anger management problems can be calmer with a pet around the house. Sometimes, just the feel of a pet in the house can do wonders on the nerves and eliminate certain aggravation. A significant point that has been brought up by animal right activists is that abuse inflicted on animals is, in many cases caused by frustration caused by an outside conflict. Outside conflicts can be caused by work stress, school or relationships. Also, people need companionship to keep stress and mental anguish at bay. When people begin questioning why they are alone, they begin doubting their own self-worth. Then suicide becomes an issue. When a person becomes depressed, their body pays the price. A depressed person will neglect to care for themselves and will slowly deteriorate. Having a pet will give said person companionship. Just being able to have someone to come home and talk to or play with could be the difference between serenity and psychosis. In women, especially, is the extra comfort provided in just being able to care for someone. Apart from that, owning a pet forces one to take on the responsibility of keeping it alive. One’s pet must be fed, watered, and kept healthy. Doing this requires us to move about.

Bilingual Education Essay -- essays research papers fc

Bilingual Education   Ã‚  Ã‚  Ã‚  Ã‚  Education is very important. There use to be a time when you didn’t have to go to school. When it was only important for men to have an education. Times have really changed. Now it is crucial for everyone in our society to have an education. Survival is the main reason: a cohesive society is another. Our schools today need to keep Bilingual education as a tool for teaching: not only for the sake of our society but also for the sense of our culture.   Ã‚  Ã‚  Ã‚  Ã‚  Bilingual education in our schools is crucial: but still there is talk about banning the use of foreign language in the instruction of our young children. We have to work to change that kind of attitude. We have to proceed from the assumption that bilingual Marquez 2 education is a sound educational proposition for all children and that it addresses the needs of all the constituencies of education. Now more than ever the words of Thomas Jefferson ring with special meaning: in 1977, in a letter to his nephew, Jefferson said: â€Å"Bestow great attention on Spanish and endeavor to acquire an accurate knowledge of it. Our future connections with Spain and Spanish America will render that language a valuable acquisition. The ancient history of that part of America, too, is written in that language†. (qt. in A Relook ’66). Hispanic leaders should plan an initiative to help Hispanic youths do better in school. It's a coming-together as a community to deal with a very pressing issue. The organizations should be composed of public officials, Marquez3 students, educators, administrators, and business people and should try to determine the biggest problems facing Latino students in their community. These groups need to work together to develop a statewide agenda. Hispanic students, according to some studies, lag behind other students in classroom performance; have the highest dropout rate of any ethnic group in the country; and, according to federal data, are less likely to pursue higher learning(Tucson ’66). We as a society, need to have a school system that prepares our students for higher education if that is their choice. Society needs to work together to change the educational process for Latino students. Consider these numbers, which we drew from As A Relook at Tucson ’66 states† Minority groups are being shortchanged by more than 20... ...important factors that influence student outcomes. There is much more work left to do by the schools if we are to enable LEP students to achieve at high academic levels. Improvement would have to focus on teachers, teaching, academic content and standards, Marquez14 accountability, school-wide leadership, program integration, parent involvement-and effective use of the native language to assure high level and meaningful learning for all students from the time they enter school. Proposition 227 removes an important tool -- use of the native language -- from the hands of educators it would only serve to make even more difficult the challenges of school improvement.   Ã‚  Ã‚  Ã‚  Ã‚  A society with no education cannot compete in the modern world. We as a society need to fight to keep Bilingual education as a teaching tool in the schooling system. Marquez15 Works cited A relook at Tucson ’66 and beyond. Washington D.C. 1973. Leibowitz, Arnold.

Happiness and Money

Money has become one of the main things In our modern life. Some people live their lives to earn money. They work hard, trying to earn as much money as they can. Some of them become crazy about It and lose their dlgnlty hunting money. They dont appreciate such Important things as family, friendship, love and other feelings. Such people become greedy, they spend their lives in loneliness. I don't deny that money influences our life a lot. As W. S. Maugham said † Money is like the sixth feeling ithout which you cannot make a complete use of the other five. I quite agree. A person can't be happy if he has no money to satisfy his natural needs. But I think that money should have a limit. A person shouldn't have too much money. It begins destroying him and becomes his curse. It is said in the Bible that â€Å"The love of money is the root of all evil. † Yes, big sums of money really bring dfferent problems because people feel very envious and Jealous of other's fortune. The m ajority of all the crimes are made because of money. I'm among the people who consider that money Is not ll-powerful.Humanity, dignity, intelligence, kindness and other good qualltles of a person can't be bought for money. We'll never be able to buy pure love, real friendship and loving and caring family. But life Isnt worth living without these things. It's not worth living if money has become the point of it either. 9HAeKC. AnpeKT Can Money Buy Happiness Can money buy happiness? Various people have various answers. Some people think that money is the source of happiness. With money, one can buy whatever he enjoys. With money, one can do whatever he likes.So, In their minds, money can bring omfort, security, and so on. Money, as they think. Is the source of happiness. But there are still a lot of others who think that money Is the root of all evil. Money drives people to steal, to rob, and to break the law. A lot of people became criminals just because they were in search of money. And in the Western countries, there is nothing that can t be bought by money. Many people lose their own lives when hunting it. I think that money is essential to life and we cannot do without money. But even though money is necessary to life, it can t buy happiness.Happiness s not something that can be measured by money. It is a state of mind. One can have plenty of money, with which he can buy whatever he wants, and at the same time he is not happy because he is never satisfied or he is troubled by various kinds of problems. Therefore, although money is necessary for a happy life, it can t buy happiness. People usually dont think too much about the meaning of money. The only Idea and concern Is to make more than they usually have. Of course having money Is a good thing because they give us the possibility to satisfy our needs and desires.People they don't usually think too much, the waste it buying expensive cars, eating out or buying expensive things Just for being in fashion. Y et, money has a certain feature â€Å"to come† easier to those who treat it well. Money tends to go to those who can use it in the most productive way to produce useful services and valuable goods and who has the ability to invest the in a profitable economical field. At the same time money uses to flow away from those who don't have the habit to use them in a profitable way. I think everyone should learn to save money and to invest it in rder to gain more.If we know the value of money we can easily manage it. It becomes a habit that leads to a successful life and career. The more effective period for learning the value of money is childhood because children usually don't value money because they don't know how much effort their parents put in their work in order to earn a certain some of money. Thus, parents are responsible for showing the real value of money when their kids are still small, than it will be much easier for them to value money without being even told about th is.
