Numerous applications are readily accessible for the average user to aid-in bypassing Internet censorship. Several technologies and techniques are associated with the formation of these applications, whereas, each of these applications deploys its unique mechanism to circumvent Internet censorship. Using anti-censorship applications in the work environment can have a negative impact on the network, leading to excessive degradation in the bandwidth, immense consumption of the Internet data usage capacity and possibly open the door for security breaches. Triumphing the war on anti-censorship applications has become more difficult to achieve at the network level due to the rapid updates and the adopted new technologies to circumvent censorship. In this study, a comprehensive overview on Internet censorship and anti-censorship applications is provided by analyzing Ultrasurf behavior, classifying its traffic patterns and proposing a behavioral-based solution that is capable of detecting and preventing the Ultrasurf traffic at the network level.展开更多
