Legal users can be authorized by the owner to access the data, while others can not access it without permissions. Further, it is desirable to enforce fine-grained access control to the outsourced data, i.

The access authorization must be controlled only by the owner in untrusted cloud environments.

Integrity[ edit ] Data integrity demands maintaining and assuring the accuracy and completeness of data. A data owner always expects that her or his data in a cloud can be stored correctly and trustworthily. It means that the data should not be illegally tampered, improperly modified, deliberately deleted, or maliciously fabricated.

If any undesirable operations corrupt or delete the data, the owner should be able to detect the corruption or loss. Further, when a portion of the outsourced data is corrupted or lost, it can still be retrieved by the data users. Encryption[ edit ] Some advanced encryption algorithms which have been applied into cloud computing increase the protection of privacy.

In a practice called crypto-shredding , the keys can simply be deleted when there is no more use of the data.

Attribute-based encryption ABE [ edit ] Attribute-based encryption is a type of public-key encryption in which the secret key of a user and the ciphertext are dependent upon attributes e.

In such a system, the decryption of a ciphertext is possible only if the set of attributes of the user key matches the attributes of the ciphertext. In order to improve search efficiency, symmetric-key SE generally builds keyword indexes to answer user queries. Numerous laws and regulations pertain to the storage and use of data. Similar laws may apply in different legal jurisdictions and may differ quite markedly from those enforced in the US.

Cloud service users may often need to be aware of the legal and regulatory differences between the jurisdictions. For example, data stored by a cloud service provider may be located in, say, Singapore and mirrored in the US. Cloud customers must ensure that their cloud providers adequately fulfil such requirements as appropriate, enabling them to comply with their obligations since, to a large extent, they remain accountable.

Business continuity and data recovery Cloud providers have business continuity and data recovery plans in place to ensure that service can be maintained in case of a disaster or an emergency and that any data loss will be recovered.

Joint continuity exercises may be appropriate, simulating a major Internet or electricity supply failure for instance. Log and audit trail In addition to producing logs and audit trails , cloud providers work with their customers to ensure that these logs and audit trails are properly secured, maintained for as long as the customer requires, and are accessible for the purposes of forensic investigation e.

Unique compliance requirements In addition to the requirements to which customers are subject, the data centers used by cloud providers may also be subject to compliance requirements.

Cloud security architecture is effective only if the correct defensive implementations are in place. An efficient cloud security architecture should recognize the issues that will arise with security management.

These controls are put in place to safeguard any weaknesses in the system and reduce the effect of an attack. While there are many types of controls behind a cloud security architecture, they can usually be found in one of the following categories: It is generally recommended that information security controls be selected and implemented according and in proportion to the risks, typically by assessing the threats, vulnerabilities and impacts.

Cloud security concerns can be grouped in various ways; Gartner named seven [9] while the Cloud Security Alliance identified twelve areas of concern. Scanning could from outside and inside using free or commercial products is very important because without a hardened environment your service is considered as a soft target.

Virtual servers should be hardened like a physical server against data leakage , malware, and exploited vulnerabilities. Scanning and penetration testing from inside or outside the cloud require to be authorized by the cloud provider. Since the cloud is a shared environment with other tenants following penetration testing rules of engagement step-by-step is a mandatory requirement. Violation of acceptable use policy which can lead to termination of the service. A number of security threats are associated with cloud data services: The following security requirements limit the threats.

Data confidentiality is the property that data contents are not made available or disclosed to illegal users. Outsourced data is stored in a cloud and out of the owners' direct control. Only authorized users can access the sensitive data while others, including CSPs, should not gain any information of the data. Meanwhile, data owners expect to fully utilize cloud data services, e. Access controllability means that a data owner can perform the selective restriction of access to her or his data outsourced to cloud.
