Literature Review About IPS And IDS Computer Science Essay

Literature Review About IPS And IDS Computer Science Essay In this chapter is to provide the study and review about Intrusion Detection System and Intrusion Prevention System which have done by expert and professor. According to (Tony Bradley, 2004), intrusion detection system (IDS) is to monitor traffic and monitor for suspicious activity. And it will give alerts to network administrator and the system. And IDS also will respond to malicious traffic by taking action to block the user or the IP address from accessing to the network. According to (Ameya Talwalkar, Symantec Manager of Intrusion Prevention Systems), Intrusion Prevention System (IPS) is a protection technology to provide security of the network. It is the front line to defence against malware, Trojans, Dos attacks, malicious code transmission, backdoor activity and blended threats. The next section will present the details of Intrusion Prevention System (IPS). Figure 1.1 is the flowchart of the key points in literature review about IPS and IDS. What is IPS What is IDS Literature review What is HIDS What is HIPS What is NIPS What is NIDS Identify Pros Cons Which are better to prevent threats Figure 1.1: Classifying the literature review 2.2 Intrusion Prevention System (IPS) There are some benefits have been justified Intrusion Prevention System as a breakthrough in the computer security. According to (Neil Desai, 2003), the main supporting idea on technical side of Intrusion Prevention System is inline network-based system. Besides that, there also have another variation of IPS which is called Layer 7 switches that have include detection and migration of Distributed Denial-if-Service attack (DDoS) and Denial-of-Service attack (DoS) based on awareness of the traffic. Every Intrusion Prevention System will generate alert based on policy or signature and they also will initiate a response which have been programmed into the system. These aleart will happen as a result for a signature match or violation of uniqueness. Secondly, according to (Benjamin Tomhave, 2004) there have a reports have identifies most of the Intrusion Detection System also have been include Intrusion Prevention System capabilities. It given a good defines set of signature or policies. So it makes sense for Intrusion Detection System work with Intrusion Prevention System capabilities. At the end, a successful deployment and the return on the investment will directly relate to how well to manage the solution and how well the network has been design. Thirdly, according to (Joel Esler, Andrew R.Baker, 2007) stated that Intrusion Prevention System are more in defence. It has been design to detect malicious packets inside the normal traffic and stop intrusions dead. And automatically block all the unwanted traffic before it bring any damage to the system rather than giving alert before or after the malicious packets have been delivered. Fourthly, Intrusion Prevention System has been added to existing firewall and antivirus solution. According to (Karen Scarfone, Peter Mell, 2007) Intrusion Prevention System is to monitor traffic and automatically drop the packets which has included malicious, scrutinizing suspicious sessions or taking other actions in immediate real time response to an attack. A good Intrusion Prevention device will check all inbound and outbound traffic. It can check on all types of packets and performs many type of detection analysis, which is a not only individual packet. It also needs to check on traffic pattern, view each of the transaction in the context of the packets come before and after. Lastly, Intrusion Prevention System product should take the advantages and implement some new detection technique and offer other type of intervention method. According to (Joel Esler, Andrew R.Baker, 2007) Intrusion Prevention System products should provide multiple modes of operation for user to choose, so they can become more confident in the product or change their network security policies. There are two types of ISP which are HIPS and NIPS. Host-based Intrusion Prevention (HIPS) is an application which monitors a single host for suspicious activity. Network-based Intrusion Prevention (NIPS) is to analyze protocol activity on the entire network. The next section will discusses about HIPS and NIPS. 2.2.1 Host-based Intrusion Prevention System (HIPS) According to (Dinesh Sequeira, 2002), Host-based Intrusion Prevention System is a software program install on individual system such as laptop, workstations or servers. When it detected an attack, the Host-based Intrusion Prevention System will block the attack at network interface level or tell the application or operating system to prevent the attack. Secondly, according to (NSS Group, 2004) Host-based Intrusion Prevention Systems relies on agents installed directly on the system being protected. Host-based Intrusion Detection Systems are binds closely with the operating system kernel and services, monitoring and intercepting system calls to the kernel or APIs in order to prevent attacks as well as records them. It may also monitor data streams and the environment specific to a particular application (file locations and Registry settings for a Web server) in order to protect these applications from generic attacks which signature has not yet exists in the database. Lastly, according to (Neil Desai, 2003) Host-based Intrusion Prevention Systems are used to protect both servers and workstations through software that runs between the systems applications and OS kernel. The software can be reconfigured to determine the protection rules based on intrusion and attack signatures. The Host-based Intrusion Prevention Systems will catch suspicious activity on the system and then, depending on the predefined rules, it will either block or allow the event to happen. At the next section, we will discuss about Network-based Intrusion Prevention (NIPS) and intrusion detection system (IDS). 2.2.2 Network-based Intrusion Prevention System (NIPS) Network Intrusion Prevention Systems (NIPS) are totally operating on a different concept which serves the purpose to build hardware or software platforms that are designed to analyze, detect, and report on security related events. Network Intrusion Prevention Systems are designed to inspect traffic and based on their configuration or security policy, they can drop malicious traffic as well as prevent the network from being contaminated with malicious data such as virus and worms. Network-based Intrusion Protection System able to detect malicious packets which are design to overlook by firewall filtering rules. Intrusion Prevent System is not a replacement for firewall but it is one part in the intelligent firewall. It is used to increase system specific or network wide security.

Comparing Canterbury Tales, Burgermeisters Daughter and the Writings o

Image of Women in Canterbury Tales, Burgermeister's Daughter and the Writings of Thomas Aquinas    What was the predominant image of women and women's place in medieval society? A rather sexist or misogynistic view--by twentieth century standards of course--was prevalent among learned clerics. The writings of the theologian Thomas Aquinas typify this view. But although the religious of Europe's abbeys and universities dominate the written record of the period, Thomistic sexism was not the only view of women's proper role. In his Canterbury Tales, Geoffrey Chaucer portrays women in a much more positive way, characterizing them as somewhat empowered. Actual historical events, such as the scandal and subsequent litigation revolving around Anna Buschler which Steven Ozment details in The Burgermeister's Daughter, suggest something of a compromise between these two literary extremes. While it is true that life was no utopia for medieval women, neither was life universally horrible or society thoroughly misogynistic.    The Church's views on women had deep scriptural roots. In his letter to Timothy, the apostle Paul writes "Let a woman learn in silence with all submissiveness" (1 Tim. 2:11). This view rests on the story of Eve's creation as a helper--not an equal--to man from the rib of Adam in Genesis. It also condemns Eve, and by association all women, for allowing the serpent to trick her into Original Sin. In Summa Theologica, Aquinas extends Paul's argument for female inferiority even farther: As regards the individual nature, woman is defective and misbegotten, for the active force in the male seed tends to the production of a perfect likeness in the masculine sex; while the production of woman comes from defect i... ...quinas did not by themselves represent the views of society at large--although society by no means completely ignored them. Aquinas and Chaucer's Wife of Bath represent two extreme views of medieval women, while the real nature of women's condition in the period lay somewhere in the middle. Any 20th century ideas of wholesale female oppression in the middle ages are relativist "myths" which serve to glamorize the modern period rather than describe historical reality. Endnotes 1 By the 11th century, roughly two centuries before Aquinas, even parish priests had become generally celibate, suggesting the widespread adoption of this practice among clergy by the 13th century (Western Heritage, 190). 2 Interestingly, the knight's crime is rape, a crime against women. His quick punishment for the rape further highlights some security enjoyed by medieval women.

Philosophy of Life Essay

The hardest part of any journey is the first step. Human life would be so much easier if we were born into it with a roadmap and a flashlight some say we actually were, but we forgot where we put them. Nonetheless, part of life is clearing your own path, making your own map, finding life’s meanings, and defining your philosophy or world view, the next hardest part of the journey, once you’ve found your truth, is living it every day walking your talk. I believe we are each here for a purpose and everything happens for a reason. We chose who we are physically, when and where we were born, and the life circumstances presented to us. Why nobody really knows. There are many possibilities. To learn lessons, like a school to be part of the overall evolution of human consciousness , to atone for karma, make up for errors and omissions in past lives, to play a role in a universal game or dramatic production, to satisfy spiritual cravings for the sensual, tactile pleasures of human life. I even read/heard someplace that Earth is the penal colony of the Universe . â€Å"Hell on Earth,† the place where sinners do badders have to work out their sentences for their evil deeds. I also heard recently that human life on earth is like a vacation: leave home, travel to wonderful new places, experience the joy and awe, then return home. I must admit that at times it feels like the vacation from hell car gets a flat tire or two it pours rain every day at the beach or worse, while camping intestinal illness on a cruise ship. Could be any of these things, could be all. I tend to lean toward the evolving karmic classroom approach. But the ultimate truth is that we are born to die. Our physical human lives are temporary, blips on the screen, a dash between the date of birth and the date of death on your tombstone. But while we are here, anything can occur, there are no accidents, nothing is impossible, miracles happen.

Robbing the Rich to Give to the Poor Essay - 917 Words

Robbing the Rich to Give to the Poor Poverty has conquered nations around the world, striking the populations down through disease and starvation. Small children with sunken eyes are displayed on national television to remind those sitting in warm, luxiourious houses that living conditions are less than tolerable around the world. Though it is easy to empathize for the poor, it is sometimes harder to reach into our pocketbooks and support them. No one desires people to suffer, but do wealthy nations have a moral obligation to aid poor nations who are unable to help themselves? Garrett Hardin in, Lifeboat Ethics: The Case Against Helping The Poor, uses a lifeboat analogy to expose the global negative consequences that could†¦show more content†¦Hardin attacks financial support to poor nations as he metaphorically compares it to the lifeboat scenerio in which the best situation is one in which no people are saved from the water thereby providing a better living condition for those already positioned in the b oat. Singer acknowledges Hardins arguments of property rights and population growth, yet combats the ethics of triage and suggests that one has a moral obligation of preventing some absolute poverty. Singer points out that absolute poverty is bad and it is within ones power to prevent some absolute power without sacrificing anything of comparable significance. Each author critiques whether one can have a moral obligation considering the impact of helping others out, yet in each position, global issues that encompass not one wealthy nation but all nations are coming into play. Religious and political views support Singer in his position that people ought to help out the poor. Singer proposes three premises that lead to the conclusion that one has a moral obligation to help out the poor. The first premise encourages one to sacrifice in order to aid another, if the sacrifice is appropriate. The second premise concludes that absolute poverty is a negative situation. The third pre mise that then leads to the conclusion that one should prevent some absolute poverty points out that it is within our power to prevent some absolute poverty. Singer is not alone in this view.
