Fifth, the security in ICN will be an integral part of the architecture and not as an overlay as is common in host-centric architectures. III. TAXONOMY OF ICN ATTACKS ICN has many security issues to be addressed. There are new types of attacks in ICN that did not occur before or did not have any significant impact in other environments. Additionally, many attacks that occur in other environments may also appear in ICN environments [19], [20], [21], [22], [23], [24]. This taxonomy classifies ICN attacks (new and legacy) into four categories as shown in Figure 2: naming, routing, caching, and other miscellaneous related attacks. This classification depends on the attacker’s main target. Although each attack is included in only one category, it may impact other categories as well. For example, both flooding and unpopular request attacks affect ICN routing and caching. In a flooding attack, the attacker’s main target is to overload and exhaust routing resources and as a consequence it affects the caching system. In unpopular requests, the attacker’s m...

...aditional as well as cloud security challenges [2]. Specific to cloud computing, the issues are many, of which some are: identity management of cloud users, multi-tenancy support, securing the security of applications, preserving privacy of the users, attaining control over the life cycle of outsourced data, etc. Among which, the issues related to privacy preserving are alone looked at in this survey. Preserving the privacy of user, his identity and data in the cloud is very mandatory. With the rise in growth of cloud computing, the concerns about privacy preserving are also getting increased [3, 4]. But reaching the peak in providing and assuring privacy-preserved data access in cloud is yet in progress and still needs much attention to attain the goal. All activities performed in an organization are recorded in log files. Log files keep track of all user activities. Also, log files are used to troubleshoot the problems, to identify users violating the policies or performing malicious activities. Log file is the most important target for malicious attacks [5]. The reason behind this is that attacker wants to leave no traces of the activities performed by him at the time of attack. There...
