Distributed Denial-Of-Service Attacks-Free-Samples for Students

Question: You are required to provide a complete report of your research project, that you chose in Assessment 3. Answer: Denial-Of-Service and Distributed Denial-Of-Service Attacks Denial-of-Service mainly refers security event which mainly occurs when an attacker prevents the authentic users from accessing the computer system or the network or the device which has been targeted. Distributed Denial-of-Service is a form of Denial-of-Service attack (Compagno et al., 2013). The main difference between the DDoS and DoS is that the DoS attack mainly uses of a single computer and internet connection in order to flood the system which has been targeted whereas in the DDoS attack the attacker makes use of multiple computer and internet connection in order to flood the resources or the system which has been targeted (He Zhu, 2012). The major challenges involved in this technology includes the following: Buffer overflow attack: The most common form of attack and this attack involves the sending of network traffic to the address of the network which has be built by the programmers so as to handle the system (Liu, Liu El Saddik, 2013). ICMP flood: This type of attack happens by leveraging the misconfigured network devices which is generally done by sending of the spoofed packets. This is initially followed by pinging each and every computer resent in the network rather than only on the single machine. After this the triggering of the network is done in order to amplify the traffic (Lonea, Popescu Tianfield, 2013). This attack can also be termed as the smurf attack or the ping of death. SYN flood: in this type of attack a request is send in order to connect to the server but despite of this handshake is never completed. This continues till all the ports are saturated with the requests and none of the requests are available for eth authentic users to get connected. After analyzing the various characteristics of the buffer overflow attack it has been seen that the traditional defense systems are not adequate. By making use of an appropriate tool the problem of buffer overflow attack can be tackled, the programmers should be educated enough prevent t or minimize the use of any kind of unsafe functions. From the point of view of a programmer it should be made sure that the secure functions are used. Keeping of the system up-to-date having the most recent security patches would greatly help in protecting the servers against various powerful threats.
