Intrusion Detection Systems in Security

Intrusion Detection Systems in Security Abstract Modern world provide the latest system of internet which is disputing for the security of information systems. The defense of information is becoming the part and parcel for internet day by day. Current Intrusion Detection systems cannot make sure to detect attacks in real time environment as it has insufficient ability to do that. To cope with latest invasions attack, database should be rationalized time to time. Systems fall squat to recognize fresh attacks due to lack of domain familiarity. If there is any lack of domain familiarity, Intrusion Detection system can fall squat to recognize new attack. In Wireless and AD HOC networks, Information security revolves into imperative role. Possibility of vulnerability to attacks rises as for their flexible nature. A few intrusion detection schemes suggested for where wired networks are not sufficient for Wireless and AD HOC networks. In AD HOC networks, it is significant for such slant that is proficient to intellect any variety of eccentric actions. In fact, it is out of ability of technology to encumber each single contravention. In this thesis I am going to model a IDS using time series techniques for wireless AD HOC network by which it can detect intruders. Time series is a technique by which we can detect intrusion. To form the rapid change of time series data, the technique applies the Auto-Regressive (AR) method, and achieves in order hypothesis test to detect the intrusion. By means of time and location correlation, the systems and modes verify the existence of anomalous commotion, as well as its occurring time and location. It is proved and demonstrates that the experimental outcomes perform better with the recommended method in detecting the intrusion. Acknowledgements Introduction Security is the major issue for the wireless and Mobile AD HOC network because it is using â€Å"AIR† as media .Research project address this part as Intrusion Detection. Mounting world cannot imagine even for a single day without computer and computer is basis on internet. Nowadays secure information of internet is becoming very high priority. Modern world emphases in a way by which it can be protect the data and information from any illicit and unauthorized access. Intrusion Detection Systems (IDS) can be differs in various techniques and advance with the objective to detect suspicious traffic in dissimilar ways. There are two significant categories of intrusion detection systems. One is called network-based intrusion detection system (NIDS) and the other one is host-based intrusion system (HIDS). The existing system that detects attacks based on looking for specific signature of identified threats. It reveals particularly that we may have two sets of data; one is of usual and common data and other one apprehensive and suspicious data. So intrusion detection systems match the data with the set of normal and suspicious data and if the deference between the two set is above a threshold value then intrusion is detected. Currently, if Internet infrastructure assault such as man in the middle attack, denial of service attacks and worms infection, have become one of the most serious threats to the network security [1]. It is very likely feasible to detect the attacks and abnormal behaviors if there is sufficient and efficient method and technique exists for monitor and examine, and it can not only make sure proceed warning of potential attacks, but also help out to recognize the reasons, source and locations of the anomalies. By this way, it may assist to restrain the attacks, sooner than they have enough time to broadcast across the network. This document represents the method, in support of detecting network anomalies by analyzing the unexpected change of time series data .With the comparison of other anomaly detection methods. We have focal point on the vibrant behavior of the network rather than using the static models. Our process and method concerns the Auto-Regressive (AR) process to model the r apid and unexpected change of time series data, and performs sequential hypothesis test in contrast with two adjoining non-overlapping windows of the time series to detect the anomalies Aim and Objectives Aim: The aim of this thesis is to design and implement a IDS for wireless network to detect and monitoring malicious activities by using time series analysis techniques. Objectives: ïÆ'Ëœ Review current intrusion detection systemïÆ'Ëœ Analyze the data with suspicious activitiesïÆ'Ëœ Design appropriate system architecture for IDSïÆ'Ëœ Implement the system using time series analysisïÆ'Ëœ Testing and evaluate the system.ïÆ'Ëœ Future work Academic Background Intrusion detection system In general, an Intrusion Detection System is not an antivirus program to detect virus or not a network logging system for detecting complete vulnerability or not a vulnerability tools which can check bus, flaws and network services. Intrusion Detection System (IDS) is a software or hardware by which we can detect hackers, male ware and bots. There are few types of Intrusion detection system like Network Intrusion Detection System, Protocol-based Intrusion Detection System, Application protocol-based Intrusion Detection System and Host-based Intrusion Detection System etc. Now a day, wireless network is increasing dramatically. We are trying to make everything which can connect to internet without wire. Compare to wired network, it is easy to capture the channel of wireless network for an intruders.Why We Need Intrusion Detection System Why we need IDS An overview of current intrusion detection system Wireless networks are extremely vulnerable to man in the middle attack, DOS and other attacks because they depend on a shared communication medium as well as depend on limited resources. Wireless ad hoc networks do not have a central control as wireless LANs and they also provide a dynamic topology. This increases the complexity of the intrusion detection schemes in ad hoc networks. Network Anomaly Detection Using Time Series Analysis According to Qingtao Wu and Zhiqing Shaos research paper, This research paper explain to detect network intrusion using time series analysis. Anomaly and sequential detection with time series data Intrusion Detection Alert Flow Processing Using Time Series Analysis Methods Processing intrusion detection alert aggregates with time series modeling Compare Wired and Wireless Intrusion Detection System (Dragan Pleskonjic) In wired network, Intruder should be attached physically. Intruder needs a direct connectivity into the network.It is possible to trace the intruder In wireless network, Intruder does not require any physical connection. So Intruder can stay everywhere. There are no difference between internal and external network so it is difficult to specify the attack whether it is insider or outsider.The border of Defense of wireless networks is weak compare to wired network.

Leader and Manager Essay

Q, Explain how someone can be a manager but not a leader, a leader but not a manager, and both a manager and a leader? Answer: The discussion between management and leadership has been considerable for a number of years. Differentiation between leadership and management is important. There is difference between manager and leader but both are important. Manger has to manage which means to accomplish and to bring about, to conduct and to feel the responsibility. On the other hand, Leader leads by guiding, and influencing in a course, direction, opinion, and action. The distinction between them is crucial (Warren Bennis 2000). In the light of this explanation we shall discuss how someone can become manager but not a leader, a leader but not a manger and both a manager and a leader? Manager but not a Leader: The term of manager is not the same for leader since the two terms are not the same. A manager must ensure the appropriate delivery of human resources and funding to meet the routine daily productivity objectives. The manager is known as detailed oriented. Mangers don not see the overall picture and are less interested regarding the long-term corporate goals and mission. They are worried about details; as a result, they do not make them a good leader. Some managers may have certain leadership qualities but they remain too focused on their daily operations and are unable to provide direction and vision to the organization. A manager plans, organizes, leads, and controls whereas a leader influence others through communication, motivation, discipline, direction and dynamics (William A. Howatt, 2008). This explanation clears that someone can be a manager but not a leader. Leader but not a Manager: People who direct, guide and coordinate a group towards an objective and a goal are known as leaders. A leader motivates subordinates to achieve the goals set by the company. Leader shows the ways and lead the ways by example and exhibit an evident commitment to set goals, motivates subordinates for achievements. Leadership qualities are inbuilt qualities and these are further developed though education and experience with certain qualities such as beliefs, values, skills, ethics and knowledge (Snell, 2008). On the other hand, the manager directs predetermined projects and goals. Managers are also involved in the hiring, scheduling and training of the employees to complete the work with efficiency and cost effectiveness. A leader is not involved in such activities; therefore, a person can be a leader but not a manager. Both a Manager and a Leader:

The American Male in John Updikes AP Essay - 918 Words

The American Male John Updike’s â€Å"AP†, is a short story that relates an episode in the life of a teenage (male) grocery store employee, circa 1961. Many critics suggest that this story is told through the eyes of the main character Sammy, and not through those of the author, John Updike. The label placed upon teenage males in modern society is often that of an à ¼ber sexist that views the female entity in only sexual lights. This assessment is supported in Updike’s story by means of diction and paragraph structure. In addition Sammy’s rash reaction to his manager’s chastising of three girls in the store is a result of his longing for the young women, rather than in his own best interest. Throughout the short story â€Å"AP†, Sammy†¦show more content†¦Sammy says, â€Å"In walks three girls in nothing but bathing suits† (15). This opening line is followed by a couple sentences describing Sammy’s own general su rroundings, but quickly reverts back to describing the physical attributes of the young women getting so caught up in the images running through his mind that he forgets his mundane task at hand of ringing up the groceries of a cheerless customer. Sammy says, The one that caught my eye first was the one in the plaid green two-piece. She was a chunky kid, with a good tan and sweet broad soft-looking can with those two crescents of white just under it, where the sun never seems to hit, at the top of the backs of her legs. I stood there with a box of HiHo crackers trying to remember if I rang it up or not. I ring it up again and the customer starts giving me hell (15). In this opening paragraph Updike clearly emphasizes what is most important to Sammy, and what is the natural progression of thoughts in this young teenage mind. Updike does an incredible job of entering a stream of consciousness in the mind of Sammy’s character that many critics fault him for as professing his personal perverted views of women. Updike continues his barrage of sexist thinking by attacking the unattractive looks of the unhappy customer by making an allusion the witch hunts of the late 1700’s in Salem, Massachusetts, however this comment is made once again through the eyes of the teenageShow MoreRelatedEssay on Male Chauvinism in John Updike and Ernest Hemingway1412 Words   |  6 PagesMale Chauvinism in John Updike and Ernest Hemingway John Updike and Ernest Hemingway struggle to portray women in a positive light; because of this, Updike’s and Hemingway’s readers come away from their stories with the effect that the lead male characters are chauvinistic, which can be defined as â€Å"prejudiced devotion to any attitude or cause† (â€Å"Chauvinism† 228).

Community College Vs. University Essay - 1343 Words

For me, the decision to go to college was never based on community college vs. university. In high school, I did not apply myself and did not make the grades to go to college. As graduation time came and went I found myself disinterested in the idea. I often felt that I wasn’t smart enough to pursue a higher education and the possibility of failure was too intimidating. It wasn’t until my daughter was born that I decided I wanted to earn a career and make myself into something she could be proud of. My dreams realized, I could see a clear path and was ready to take the plunge. However, my options were limited. Thanks to my lack of high school aspirations, I only had one choice: community college. Community college may seem like a school for underachievers, but in reality, its programs cater to many different individuals: High school students, adults returning to pursue (or finish) a degree, and people who are interested in taking recreational classes. Many community col lege students are programmed differently and they have different studying techniques and their own set pace for learning. The great thing about community college is that it can accommodate all of these individuals. Community college provides the tools and the know-how to help their students succeed.
