Abstract— Now a days, the big data is stored on the
internet called as clouds. With usage of cloud storage users can
store their data on the internet. Cloud computing provides
various services to the users. Data storage is one of them. But it
is observed that there is very big problem of data stealing
through the internet. More is the problem of data leaking &
attacks on the data on clouds. The intention of this paper is to
attain data security of cloud storage and to put together
equivalent cloud storage security strategy. These strategies are
combined with the outcomes of existing data by considering
the security risks & user data on cloud storage & move
towards the appropriate security technique , which is based on
properties of cloud storage system. The paper will go in to
subtle elements of information assurance strategies and
methodologies utilized all through the world to guarantee most
extreme information insurance by diminishing dangers and
dangers. Accessibility of information in the cloud is helpful for
some applications yet it postures hazards by presenting
information to applications which may as of now have security
provisos in them. Also, utilization of virtualization for
distributed computing may chance information when a visitor
OS is keep running over a hypervisor without knowing the
unwavering quality of the visitor OS which may have a
security proviso in it. The paper will likewise give a knowledge
on information security perspectives for Data-in-Transit and
Data-at-Rest.
Keywords—Cloud Computing, Cloud Storage, Data Security,
Cloud Services.
I. INTRODUCTION
Basically the concept of cloud computing is invented due
to the need of various services like networking , security,
storage, and artificial intelligence as well as standard office
applications. So, cloud computing can be defined as the
program outsourcing. Using cloud, one can use various
applications & software from anywhere in the world, which
are provided by some third party called as cloud. There are
various benefits of cloud computing such as,
x Self-service provisioning in which the users can use
the various compute resources for any kind of work
demand.
x Elasticity, in which one can increase the data usage
as demand increases & decrease the data usage as
demand decreases. This reduces the massive
investment.
x Workload flexibility, in which Cloud service
providers frequently implement outmoded resources
to ensure flexible storage and it keep users' vital
workloads working across many global regions.
x Migration flexibility, in which the users can transfer
the data from one cloud to another cloud as per
requirement.
Cloud is categorised into 3 types,
1. Infrastructure as a service (IaaS) in which the cloud
hosts essentials of infrastructure like servers,
software, storage, etc. Also provides the data
security, maintenance, data backup, etc.
2. Software as a service (SaaS) in which various
applications are able to use.
3. Platform as a service (PaaS) in which the users can
develop their own application, run it and manage
those applications on cloud without getting stuck
into code, infrastructure & storage.
Fig. 1. Cloud Computing Types
Generally, cloud provides the services as networking,
security, storage, artificial intelligence, etc. So, to avail those
services, various organizations rent to the cloud service
providers. Now, here is the responsibility of the vendor to
provide the services to the customers as per their
requirement. But, every coin has two sides, i.e. there are
some problems with this super technology such as data
security. Means, when the confidential data is uploaded on
the cloud, it may be hacked by some third party, so the main
issue is of the big data security stored on the cloud now a
days.
A. Cloud Storage
Distributed storage is innovation that enables you to
spare documents away, and afterward get to those records by
means of the Cloud. We should separate this definition. To
begin with, capacity is the PC's capacity to spare documents
