Analysis of Security in cloud hosted Service & Self Hosted Services
註釋As more and more organizations consider moving their applications and data from dedicated hosting infrastructure, which they own and operate, to shared infrastructure leased from `the cloud', security remains a key sticking point. Tenants of cloud hosting providers have substantially less control over the construction, operation, and auditing of infrastructure they lease than infrastructure they own. Because cloud-hosted infrastructure is shared, attackers can exploit the proximity that comes from becoming a tenant of the same cloud hosting provider. As a result, some have argued that that cloud-hosted infrastructure is inherently less secure than the self-hosted infrastructure, and that it will never be appropriate for high- stakes applications such as health care or nancial transaction processing.
