Isolation Failure
Probability: Private Cloud -- Low; Public Cloud -- Medium
Impact: Very High
Risk: High
Not a likely risk for private cloud users, isolation failure can pose a serious threat to customers of public cloud services. "This class of risks includes the failure of mechanisms separating storage, memory, routing and even reputation between different tenants of the shared infrastructure (e.g., so-called guest-hopping attacks, SQL injection attacks exposing multiple customers' data stored in the same table, and side channel attacks," explains ENISA. Customers could lose sensitive data and experience service interruptions.
