A method of DDoS attack detection using HTTP packet pattern and rule engine in cloud computing environment
TL;DR: This study proposes a method of integration between HTTP GET flooding among Distributed Denial-of-Service attacks and MapReduce processing for fast attack detection in a cloud computing environment and experiments show that the proposed method is better than Snort detection because the processing time of the former is shorter with increasing congestion.
Detecting Web based DDoS Attack using MapReduce operations in Cloud Computing Environment.
TL;DR: The proposed method of integration between HTTP GET flooding among DDOS attacks and MapReduce processing for a fast attack detection in cloud computing environment is better than Snort detection method in experiment results because processing time of proposed method is shorter with increasing congestion.
Journal ArticleDOI
Text analysis for detecting terrorism-related articles on the web
TL;DR: Experimental results show the proposed method to use word similarity based on WordNet hierarchy and n-gram data frequency effectively extracts context words from the text and identifies terrorism-related documents.
Proceedings ArticleDOI
Detection of cross site scripting attack in wireless networks using n-Gram and SVM
TL;DR: The method to detect themalicious SQL injection script code which is the typical XSS attack using n-Gram indexing and SVM Support Vector Machine is proposed and the more improved results than existing methods could be seen in the malicious script code detection recall.
Journal ArticleDOI
Tracing Trending Topics by Analyzing the Sentiment Status of Tweets
TL;DR: This study takes the basic approach by tracking events considered to be exciting by users and then analyzing the sentiment status of their Tweets collected between November and December 2009 by Stanford University, suggesting that users tend to be happier during evenings than during afternoons.
