An injection attack is where a malicious actor sends commands or other arbitrary data through input and data fields with the intent of having the application or system execute the code as part of its normal processing and queries. This can trick an application into exposing data that is not intended or authorized to be exposed, or it can potentially allow an attacker to gain insight into configurations or security controls. Missing function-level access control exists where an application only checks for authorization during the initial login process and does not further validate with each function call. Cross-site request forgery occurs when an attack forces an authenticated user to send forged requests to an application running under their own access and credentials. Cross-site scripting occurs when an attacker is able to send untrusted data to a user's browser without going through validation processes.

Public clouds, such as AWS and Azure, are massive systems run by major corporations, and they account for a significant share of Internet traffic and services. They are always expanding, offer enormous resources to customers, and are the least likely to run into resource constraints compared to the other deployment models. Private clouds would likely have the resources available for specific uses and could not be assumed to have a large pool of resources available for expansion. A community cloud would have the same issues as a private cloud, being targeted to similar organizations. A hybrid cloud, because it spans multiple clouds, would not fit the bill either, without the use of individual cloud models.

Multitenancy is the aspect of cloud computing that involves having multiple customers and applications running within the same system and sharing the same resources. Although considerable mechanisms are in place to ensure isolation and separation, the data and applications are ultimately using shared resources. Broad network access refers to the ability to access cloud services from any location or client. Portability refers to the ability to easily move cloud services between different cloud providers, whereas elasticity refers to the capabilities of a cloud environment to add or remove services, as needed, to meet current demand.

Shares are used within a cloud environment to prioritize resource allocation when customer requests exceed the available resources. Cloud providers utilize shares by assigning a priority score to each customer and allocating resources to those with the highest scores first. Scoring is a component of shares that determines the actual order in which to allocate resources. Neither weighting nor prioritization is the correct term in this case.
