Denial of Service (DoS) attacks

Denial of Service (DoS) attacks Denial of Service (DoS) attacks may become a major threat to current computer networks. Even a teenager can lunch the DoS attack by using readymade DoS tools. DoS attack is an attack to slow down the legitimate users computer by overloading its resources. The goal of DoS attack is to prevent the legitimate users to access the services, not to gain an unauthorized access or resources. Attackers prevent the legitimate users to access the services by doing flooding of the network, disrupt connections between two machines, and disrupt service to a specific user or system. In simple words, Denial of Service attack on a network is designed to take down the network by sending a large number of random packets. Lunching DoS attack I use the Panther2 tool to lunch a DoS attack. Panther2 is UDP-based attack design for 28.8 or 56 kbps connection. It would do great if attacker used it from fast connection. Panther2 is a nuker that pings multiple ports at once and floods the firewalls with 1000s attacks in very small time and causes firewall shutdown if used from computers with fast connections. Open the panther2 application to do DOS attack. Panther2 application Type the victims ip in the Host box that is 192.168.1.1 and choose the ping -v icmp 127.0.0.1 1024 from the Data drop down menu and click Begin button to lunch the Denial of Service attack. The effect of victims machine Pings the multiple ports at once in very small time increase the CPU consumption and cause the computer resources unavailable. The victims firewall has to analysis the various ports and detects the every packet that is sent from the Panther2. In my attack, the machine of the victim just slow down a little bit. He complains that browsing the Network Places is take longer than normal and when he try to copy the file from one computer in the network, the process also takes longer than normal. But surfing the internet is still fine. Protection from DoS or DDoS attacks Denial of Service (DoS) attacks may become a major threat to current computer networks. Yahoo, E*Trade, Amazon.com and eBay were attacked by DDoS in the week of February 7, 2000. It can cause the loss of a lot of money if the attacker attacks like those sites. Defending and protecting your machine from DoS or DDoS attack is critical. There is no method to 100% secure from DoS or DDoS attack. There are various methods to prevent the machine from DoS or DDoS attack. Among these, there are main important 6 methods. They are Disabling unused services and ports Applying Security Patches and Updating the Software Using Firewall and Intrusion Detection System (IDS) software Protection against DDoS Attacks Based on Traffic Level Measurements Filtering Dangerous Packets Tuning System Parameters Disabling unused services and ports Disabling the UDP echo or character generator services will help to defend against DoS or DDoS attacks if they are not required. The unused network services and ports should be disabled to prevent the DoS or DDoS attacks. Applying Security Patches and Updating the Software The machine should be applied the latest security patches and update the system software. Applying security patches and updating the software can reduce the current system bugs and use the latest security techniques available to minimize the effect of DDoS attacks. It cannot protect when the attacker uses the packets that are similar to legitimate traffic or pure flood network bandwidth. Using Firewall and Intrusion Detection System (IDS) software A host computer and a network can guard themselves against being a victim of a DDoS attack if the system uses IDS software. IDS detect DDoS attacks either by using the database of known signatures or by recognizing anomalies in system behaviors. Firewall can protect the unauthorized accesses from the outsiders. It blocks the unauthorized incoming traffics to the system, so the system must be safe within the safe limitation. Protection against DDoS Attacks Based on Traffic Level Measurements It defense against the DDoS attack by monitoring the traffic levels. A DDoS module is attached to a given server making it a virtual server and the module relies on a buffer through which all incoming traffic enters. If the traffic level becomes higher, almost all incoming packets will be dropped to make the stable of the machine. Illegitimate traffic is recognized by its higher mean of traffic level and can be effectively blocked the DDoS attacks. Filtering Dangerous Packets Most vulnerability attacks send specifically crafted packets to exploit vulnerability on the victims machine. It requires inspection of packet headers and often deeper into the data portion of packets in order to recognize the malicious traffic and defense them. But most firewalls and routers cannot do the data inspection and filtering also requires the use of an inline device. Intrusion Prevention Systems (IPS) could be used to filter or alter them in transit. IPS acts like IDS, it recognizes the packets by signatures. Using IPS in high bandwidth networks can costly. Tuning System Parameters Tuning system parameters will help protect the network from small to moderate DoS or DDoS attacks. Processor Utilization some programs can show the processor loads. If a single program unusually take the high amount of CPU (>90%) this may be a vulnerable application targeted by a DoS attack. Network I/O performance dropped packets or network collisions can be seen by netstat command in the command prompt. Memory Utilization the memory usage of the programs can be viewed from Task Manager. Having large amount of free memory can be stabilized the system. I used HxD Hexeditor version 1.6.1.0 and Hex Workshop version 6.0 to decipher the text. HxD Hexeditor version 1.6.1.0 Open the HxD application. The Deciphered text is A password is a combination of characters associated with your user name that allow you to access certain computer resources. To help prevent unauthorized users from accessing those computer resources, you should keep your password confidential.

Harley Davidson Marketing Strategy Essay

1. Executive Summary Harley Davidson is an American motorcycle company founded in 1903 by William S. Harley and Arthur Davidson. In the following 108 years of business, the Harley Davidson business has endured the peaks and troughs of economies to be recognised as an iconic brand in the motorcycle industry. After breaking records on the race track, Harley Davidson secures contracts to supply 60000 motorcycles American military during World War II, exposing thousands of servicemen to the Harley Davidson brand. Through clever marketing and positioning, Harley Davidson has shed the bearded biker image, and now appeals to people from varying backgrounds all over the globe. The following report will provide a situational analysis of the Harley Davidson Motorcycle Company and discuss some of the marketing strategies that have enabled Harley Davidson to adapt to its market place and create customer loyalty rarely seen in today’s business environment. Oliver as cited in Sorce (2002) discusses the aspects of developing customer loyalty, and four elements that are necessary in order to do this; 1. The product must be perceived as superior by a large enough segment of the firm’s customers in order to be profitable. 2. The product must be subject to adoration (or focused commitment). 3. The product must have the ability to be embedded in a social network. 4. The firm must be willing to expend resources to create the village (Sorce, 2002). The discussions in the following report will establish without doubt that Harley Davidson has in fact achieved a remarkable level of customer loyalty. By creating this loyalty Harley Davidson engages their customers and enables them to focus on developing long term relationships with them. It would be easy to say that Harley  Davidson is a company that sells motorcycles. In reality they are not just selling motorcycles, they are creating images of a lifestyle; the motorcycle is merely a repr esentation of this image. The motorcycle does not project the image; it fills the image. (FÄ ±rat, Dholakia & Venkatesh, 1995) 2. Situational Analysis 2a.Strengths Harley Davidson is fortunate to hold a market position that boasts multiple strengths and opportunities that potentially outweigh their threats and weaknesses. In 2010 Harley Davidson gained approximately 55% of the heavy weight motorcycle market in the USA, a marginal increase from 2009 and substantially higher than 2008 (Harley Davidson, 2011). This is a promising trend in economically uncertain times. The brand recognition of Harley Davidson continues and remains a distinct advantage over its competition, especially in the American market. In recent years, Harley Davidson has made a concerted effort in targeting a wider range of customers with their range of motorcycles. By the end of 2010 Harley Davidson has also become the number 1 seller of heavy weight motorcycles to women, Hispanics and African-Americans. Another success has been in a market of which they had been previously criticised for not targeting well, young adults between the ages 18-34; as of 2010 they now hold that number 1 position as well (HD, 2011). There is little doubt that the real success in target marketing has been the development of the Harley Owners Group (HOG). HOG membership is given with all purchases of a new Harley Davidson motorcycle; affording the members benefits such as roadside assistance, HOG magazine, Fly and ride rental deals, touring information and event information. The HOG group sums it up well on their website; â€Å"the Harley Owners Group is more than just a motorcycle organisation. It is one million people around the world united by a common passion: making the Harley-Davidson dream a way of life† (HD, 2011). 2b.Weaknesses Although the USA market is very strong for Harley Davidson, they are making slow progress in gaining market share in the international market. The customer loyalty that Harley Davidson enjoys in the USA is challenged internationally by rival heavy weight manufacturers such as BMW, Triumph, Honda and Kawasaki. Internationally, Europe has the largest demand for heavy weight motorcycles; in which Harley Davidson has only managed to acquire less than 13% of this lucrative market (HD, 2011). 2c.Opportunities One of Harley Davidson biggest opportunities is intrinsically linked to its major weakness. Internationally there is a large bit of a very big pie that Harley Davidson has not managed to attain. Although Harley Davidson has less than 13% of the heavy weight motorcycle sales in Europe, they manage to hold the number 2 ranking in this market. This ranking indicates that no one competitor owns the heavy weight market in Europe and suggests that the customer loyalty amongst the competitors is far from what Harley Davidson enjoys in the USA. Having achieved the number one ranking for sales to women, Harley Davidson still have a large potential customer base in attracting more women riders. Since 2007 Harley Davidson has doubled its marketing spend and released bikes more suited to women riders, who now account for 12% of Harley Davidson sales in the USA (Clothier, 2010). 2d.Threats Aside from the usual threats posed by competitors in the heavyweight market, Harley Davidson will face the same threat that looms for most manufacturers†¦economic uncertainty. Although the current economic situation in the USA is unlikely to threaten the current Harley Davidson market share in its core market; it may certainly threaten its financial stability. The loyal customers in the USA may not turn away from Harley Davidson, but they will be more likely to delay their planned upgrades and apparel purchases. The economic threats in the international market may pose a more serious threat to Harley Davidson. Not only are there financial pressures present in all international markets, but they are more susceptible to fluctuations in foreign exchange rates. If these pressures cause Harley Davidson dealers to close their doors it can lead to a downward pressure on motorcycle prices, reduced retail coverage, reduced servicing capabilities and a general negative impression on Harle y Davidson as a brand. (HD, 2011) 3. Analysis of Harley Davidson Case Study Joanne Bischmann, VP of Marketing for Harley-Davidson identifies the company’s value proposition by stating â€Å"We fulfil dreams inspired by the many roads of the world by providing extraordinary motorcycles and customer experiences. We fuel the passion for freedom in our customers to express their own individuality† (Pearson Prentice Hall,2011). The viewer is left with a clear understanding that Harley Davidson is not just about selling motorcycles; they are selling visions and lifestyles. It is interesting to note that even Joanne Bischmann has been sold on this; she explains bluntly that she would rather give up most other things than her Harley. It is also customary for other Harley Davidson executives to attend HOG rallies, enabling them to not only get a feel for their product, but develop an understanding of the people that purchase their product. (Berry, 2002) There is little doubt that one of Harley Davidson’s greatest successes in its marketing strate gies has been the conception of the Harley Owners Group (H.O.G). H.O.G has given Harley Davidson continued and authorised access to their customers and helped the company to create a definite brand community. By establishing this brand community, H.O.G has nurtured a relationship between the customer and the company, the brand, the company’s products and importantly, fellow customers. The rallies and functions organised by H.O.G has brought customers and groups together unrelated in any way other than the mutual appreciation of a Harley Davidson product (MacAlexander, Schouten & Keoning, 2002). In doing this Harley Davidson has managed to deliver on the promises of benefits in their value proposition, making it a reality rather than just words. Harley Davidson has developed a customer loyalty that would make most manufacturers envious. Through clever strategic marketing Harley Davidson has established a quality product that provides the loyal consumer with exactly what they are seeking. In essence they have created a following of â€Å"True Friends† as described by Armstrong and Kotler (2011); The firm wants to make continuous relationship investments to delight these custom ers and nurture, retain, and grow them. It wants to turn true friends into true believers who come back regularly and tell others about their experience with the company. It would be difficult to match the above definition any closer than H.O.G manages to do so. They bring together passionate individuals and groups who are fiercely loyal to the Harley Davidson brand. It would be difficult to believe that the members do not wax  lyrical about their adventures and travels with H.O.G delivering a whole new range of potential customers to Harley Davidson. When considering the Harley Davidson brand community it seems likely that the groups Armstrong and Kotler (2011) term Strangers or Barnacles would account for a minimal share of their customer base. With the presence of so many â€Å"True Friends†, Harley Davidson has undoubtedly established a customer equity base of considerable proportion. It is not only the fact that a Harley owner is a loyal fan; approximately 75% of them are repeat buyers. The customers have bought in to the romance and lifestyle of the brand supporting the idea that â€Å"investment in a Harley is more than financial and the role of the bike is more than functional† (Schembri, 2008). In addition to the cus tomer equity, this principle may in turn lead to actual financial equity as indicated by MacAlexander et al. (2002) many loyal customers have a tendency to invest in the company’s stock, their emotional investment in the welfare of the company and a desire to contribute to the success of the company. Although the customer loyalty factor no doubt accounts for substantial customer equity for Harley Davidson, the fact that they manufacture a quality product is of even more importance. If the product was not first rate, no amount of marketing would be able to attract new buyers and convince current consumers to repurchase motorcycles. Harley Davidson has made changes to its product range in order to meet the demands of what they call their outreach customers. By introducing a range of motorcycles that are more suited to women buyers they have been able to attain the number 1 status in that market. Some models of their Sportster range have had the seats lowered and weights reduced by 150lbs in order to appeal to the woman rider (HD, 2011). 4. Recommendations Harley Davidson USA and Europe are the key business regions for the company, accounting for 83% of the new motorcycle sales in 2010 (HD, 2011). It will be difficult to significantly grow the business in the USA due to their already large market share and the continuing unsettled economic conditions. 36 Harley Davidson dealers in the USA closed during 2010 with more stores expected to close during 2011 (HD, 2011). If any business growth is to be seen in the USA market, the outreach customers will be the likely sector that can contribute towards this. Harley Davidson needs to keep focusing on  the outreach customers and target their marketing to this group. There is still significant room for growth in the international market for Harley Davidson. The major risk factor associated with this market will also be the uncertainty in the economic conditions. Europe financial instability will be of concern to any company wishing to grow any business in non-essential items. It may be prudent of Harley Davidson to wait and see how the European markets recover from recent stresses. With Europe being the largest international market of heavy weight vehicles (HD, 2011), Harley Davidson need to keep a strong presence in the region. In particular, there seems to be good potential in targeting the outreach customers in this region. Harley Davidson Finance also has some potential to grow in the near future. Internal finance options for buyers is important the business and the likelihood that financing options for buyers will be made easier due to this option. 5.
