Network function virtualization (NFV) enables flexible deployment of middleboxes as virtual machines running on general hardware. Since different middleboxes may change the volume of processed traffic in different ways, improper deployment of NFV middleboxes will result in hot spots and congestion. In this paper, we study the traffic changing effects of middleboxes, and propose software-defined networking...
Nowadays, Online Social Networks (OSNs) has become one of the most common ways among people to facilitate communication. This has made it a target for attackers to steal information from influential users and has brought new forms of customized attacks for OSNs. Attackers take advantage of the user's trustworthiness when using OSN. This exploitation leads to attacks with a combination of both classical...
Network function virtualization enables flexible implementation of network functions, or middleboxes, as virtual machines running on standard servers. However, the flexibility also creates a challenge for efficiently placing such middleboxes, due to the availability of multiple hosting servers, capability of middleboxes to change traffic volumes, and dependency between middleboxes. In this paper,...
