Design a Hybrid Algorithm for Cloud Computing Security
Salah Talha Babiker, Ayman A. Ali · 2015
Data are at the core of IT security concerns for any organization, whatever the form of infrastructure that is used. Cloud computing does not change this, but cloud computing does bring an added focus because of the distributed nature of the cloud computing infrastructure and the shared responsibilities that it involves. Security considerations apply both to at rest (held on some form of storage system) and also to in motion (being transferred over some form of communication link), both of which may need particular consideration when using cloud computing services. Essentially, the questions relating to for cloud computing are about various forms of risk: risk of theft or unauthorized disclosure of data, risk of tampering or unauthorized modification of data, risk of loss or of unavailability of data. It is also worth remembering that in the case of cloud computing, data assets may well include things such as application programs or machine images, which can have the same risk considerations as the contents of databases [1, 2]. Cloud computing provides a framework for supporting end users easily attaching powerful services and applications through Internet. Denial of- Service (DoS) attack or Distributed Denial-of-Service (DDoS) are major security issues in cloud environment. [11, 18] Moreover, we present a distributed architecture for providing intrusion detection in Cloud Computing, which enables Cloud providers to offer security solutions as a service. It is a hierarchical and multi-layer architecture designed to collect information in the Cloud environment, using multiple distributed security components, which can be used to perform complex event correlation analysis.
