Backing up our databases to the public cloud is an important strategic focus for us going forward in order to save money, scale our backup and DR operations, and to ensure our applications are always available to customers and business users worldwide. Over the past few years, many organizations have started to deploy public cloud for backup and Disaster Recovery (DR). Data recovery approaches with respect to digital forensics can be introduced for the sake of data management after a system encounters with an attack or any disaster like crash of vital data. These approaches often used by organizations to experience the reactive majors after a crash of data. Cloud-based business flexibility can provide an attractive alternative to traditional disaster recovery, offering rapid recovery time associated with a dedicated infrastructure and the reduced costs that are consistent with a data recovery model. This paper discusses one of the techniques to implement application for DR and describes how organizations can use cloud computing to help plan for both the routine interruptions to service-server hardware failures ,cut power lines, and security breaches-as well as more-infrequent disasters. The paper provides key considerations for the transition of replicas once a peer in the system encounters an attack in the private cloud-based business resilience. That is, a machine, once experiences calamity like instance failure of data and so on, DR can be carried out by an application discussed in this paper to recover the data by extracting a last Restore point (RP).

It allows users to free themselves of tasks of resource management i.e. most efficient use of resources. It also allows centralization of information and resources so that the users can access them from anywhere using the internet. Generally the resources used to provide services belong to a third party. As the users don’t have to invest capital in such resources it decreases costs. Even though cloud model is lucrative, users have been hesitant in adopting it, the major reason being security concern regarding their private data. In this paper we discuss about various security concerns in cloud environment.

Its model of computing as a resource has changed the landscape of computing as we know it, and its promises of increased flexibility, greater reliability, massive scalability, and decreased costs have enchanted businesses. Cloud Computing holds the potential to eliminate the requirements for setting up of high-cost computing infrastructure for IT-based solutions and services that the industry uses. It promises to provide a flexible IT architecture, accessible through internet from lightweight portable devices. This would allow multi-fold increase in the capacity and capabilities of the existing and new software. In a cloud computing environment, the entire data resides over a set of networked resources, enabling the data to be accessed through virtual machines. Since these datacenters may be located in any part of the world beyond the reach and control of users, there are multifarious security and privacy challenges that need to be understood and addressed. One can never deny the possibility of a server breakdown that has been witnessed, rather quite often in the recent times. There are various issues that need to be addressed with respect to security and privacy in a cloud computing environment. This extensive survey paper aims to elaborate and analyze the numerous unresolved issues threatening the cloud computing adoption and diffusion affecting the various stake-holders associated with it.

As mobile computing has become more popular over the past decade, it has been under continuous development with advances in hardware, software, and network. Mobile computing has various applications in our everyday life. The convergence of Internet and mobile computing enables personalized access to online services anywhere and anytime. Entities (e.g., users, services) have to authenticate themselves to service providers in order to use their services. An entity provides personally identifiable information that uniquely identifies it to a Service Provider. Due to the rapid spread of smart phones and social network service, the use of Interne applications has increased and their need for bandwidth has begun to exceed the capacity of 3G networks. This has caused a reduction in speed and service quality. The increase in mobile network users has caused identity management problems for mobile service providers. Therefore, in this paper, proposed system is designed to overcome this problem Improved Identity Management protocol is used to breaks up loads, which are allowed by the existing Identity Management 3G protocol's mutual authentication via mobile operator process, by sending some parts to an Internet application service provider to enhance mobile and ID management at the service provider and by reducing the network and process loads from information handling and packet transmission. The proposed system used the RC-5 algorithm to increase the speed and security in mobile cloud computing providing private key and public key with existing method and it is fulfilling the needs of cloud users and Providers.

For contributing in this domain we have proposed a scheme for Street light controlling using distributed topology control (TC). The optimize version of A3 protocol reduces the number of messages send/received by the sensors which ultimately leads to the reduction of energy requirement. Experiments are carried on street light scenario for different no. of nodes by maintaining communication using Zigbee protocol. The performance of our extension is evaluated using, no. of messages send/receive & energy consumed during topology building and our approach is having good results as compared to the approach used for this type of network. communication and sensing range 100m and 20 m respectively. The sink node and remaining nodes is assumed to have the initial energy of 1000mJoule/Node.

to adopt it into their mainstream business. A strong thrust on the use of virtualization technology to realize Infrastructure-asa-
Service (IaaS) has led enterprises to leverage subscription-oriented computing capabilities of public Clouds for hosting
their application services. A seldomly discussed, but in this regard highly relevant open issue is the ability to perform digital
investigations. This continues to fuel insecurity on the sides of both providers and customers. In Cloud Forensics, the lack of
physical access to servers constitutes a completely new and disruptive challenge for investigators. Due to the decentralized
nature of data processing in the Cloud, traditional approaches to evidence collection and recovery are no longer practical.
The main disturbing element of the security of the cloud i.e. the DDoS attacks has led to the establishment of various
technologies in order to gain defense against DDoS attacks. This paper gives the implementation of a forensic technique
which detects DDoS attack and is used as a service provided by CSP.

generated every day. Cloud Computing is a solution for this in a cost effective manner. Cloud Computing provides on demand
resources as services to client. Cloud is highly scalable, flexible and platform in dependable. Although it is benefiting
the clients in several ways but as data is stored remotely it has many security loopholes like attacks, data loss, other authentication
and security issues. In this paper an authentication model is proposed for cloud computing based on Kerberos protocol
using threshold cryptography to provide more security and to increase the availability of key. This model can also benefit by
filtering the unauthorized access and to reduce the burden of computation and memory usage of cloud provider against authentication
checks for each client. It acts as a third party between cloud server and clients to allow authorized and secure
access to cloud services. In this paper we will take a review of related work for cloud security. In next section we will discuss
the proposed architecture and its working.
