Cloud security refers to policies, technologies, and controls used to protect cloud computing data, applications, and infrastructure. Cloud service providers must comply with security and data security regulations within their country. Auditing companies audit cloud services to ensure they meet compliance regulations, such as FISMA, HIPAA, and SOX in the US. Users may have to adopt more expensive hybrid cloud models for compliance. Storage auditing services verify that cloud data meets compliance standards. Compliance reduces fees from regulation violations and benefits large cloud companies.
