Essays on Denial Of Service

ABSTRACT

Cloud computing employs the use of parallel and highly computed processors to virtually and remotely deliver services. This is an important factor forenterprises whose processing resources are limited and who suffer limitations on the manpower and data storage. This notwithstanding, cloud computing faces a serious threat in the area of data security. This is because the attackers have become very opportunistic and look for any slight loophole that will enable them to bypass the server securities within the cloud computing environment. It is thus important to come up with a systematic approach that can help in identifying the vulnerabilities ...

1 a) There is two categories of passive attacks: Traffic Analysis and release of message content. In a release of message contents attack, an eavesdropper listens and pursues information shared between two individuals. In traffic analysis attack, an eavesdropper hijacks the conversation between two parties and analysis the packets send between the two parties to find out passwords within those packets. 1b) There are four categories of active attacks: Masquerade, Replay, and modification of message and denial of service.
