Cloud computing offers many benefits to organizations, but these benefits cannot be realized if there is not proper IT security and privacy protection strategy when using the cloud.

Most organizations have compliance policies. security, privacy and process to secure their IP and assets.
In addition to this, organizations must establish a formal governance framework that describes the chains of responsibility, authority, and communication.
This describes the roles and responsibilities of those involved, how they interact and communicate, and the general rules and policies.
It is important to audit the compliance of IT system providers that host applications and data in the cloud.
There are three important areas that must be audited by customers of the cloud service: the internal control environment of a cloud service provider, access to the corporate audit trail and the security of the installation of the cloud service .
The use of the cloud means that there will be employees of the cloud service provider who can access data and applications, as well as employees of the organization that perform operations on the provider system.
Organizations should ensure that the provider has processes that govern who has access to the client's data and application.
The supplier must allow the client to assign and manage roles and authorizations for each of its users. The provider must also have a secure system to manage unique identifications for users and services.
Data is the core of all IT security concerns for any organization. Cloud computing does not change this concern, but it presents new challenges due to the nature of cloud computing.
The security and protection of data must be guaranteed both at rest and in transit.
The privacy and protection of information and personal data are crucial, especially since many important financial companies and institutions are suffering from data breaches.
The privacy of personal information is related to the personal data that an organization possesses, which could be compromised by negligence or errors.
It is essential that the privacy requirements are addressed by the cloud service provider. Otherwise, the organization should consider looking for a different provider or not placing confidential data in the cloud.

Cloud service providers must block malicious traffic and allow legitimate network traffic. Unfortunately, cloud service providers will not know what network traffic their customers want to send and receive.
Therefore, organizations and providers must work together to establish security measures and provide the tools needed to protect the system.
The security of an IT system is also based on the security of the physical infrastructure and facilities. Organizations must have the guarantee of the provider that there are appropriate controls.
Infrastructure and facilities must be maintained in safe and protected areas against external and environmental threats.
