Could Computing is emerging as a enticing field in IT sector because of its

numerous benefits ranging from its efficiency to scalability .Cloud Computing

changes the total scenario of today's IT infrastructure because of its

flexibility and computational performance. Cloud has a major advantages of

all the above technologies by providing cent percent piracy free software

environment , low manpower load on software updates and maintenance.

Cloud gives the power to the consumer to access related data anywhere with

much more computational power without any extra hardware cost. Cloud

computing is a increased level of Virtualization, grid computing and SOA.

However compromises are being made because of security .Since cloud

computing share resources via the network. Thus arises security problems to

develop cloud computing application. Security is the major concern of cloud

computing .Almost 70% of consumers before adoption show there concerns

on cloud's security. The tag "access anywhere" gives the security concern a

boost.

This paper propose a secure cloud model known as SeCloud. Some important

security services, including authentication, confidentiality and integrity, are

provided in cloud computing system. This paper covers the cloud security

details like its loopholes, its vulnerabilities , effective exploits ,possible

backdoor, various hacking techniques like SQL injections, Xss , RFI, xml

signatures, XDos and server misconfiguration , may used in it and the

effective way to prevent all of the above using SeCloud.

Using an appropriate model with its effective audit by examining the various

vulnerabilities , we can make a cloud architecture which is secure.CCM(cloud computing Model) cannot be implemented without a proper security

model to be introduce into CCM.API plays important role in the security

breach of clouds, implementation of better API controls.

For a better cloud model which is secure we should follow authentication,

authorization, and audit (AAA) model. Also giving certain guidelines on SSO,

identity management, regulations for proper usage and logs thus preventing

the data leakage in clouds. By securing the cloud we can easy implement the

architecture of enterprise cloud model and use the cloud computing power

to its fullest.
