Justify cloud security challenges in detail.

Cloud Computing

Cloud computing security challenges fall into three broad categories:

Data Protection: Securing your data both at rest and in transit

User Authentication: Limiting access to data and monitoring who accesses the data

Disaster and Data Breach: Contingency Planning

Data Protection

Implementing a cloud computing strategy means placing critical data in the hands of a third party, so ensuring the data remains secure both at rest (data residing on storage media) as well as when in transit is of paramount importance. Data needs to be encrypted at all times, with clearly defined roles when it comes to who will be managing the encryption keys. In most cases, the only way to truly ensure the confidentiality of encrypted data that resides on a cloud provider's storage servers is for the client to own and manage the data encryption keys.

User Authentication

Data resting in the cloud needs to be accessible only by those authorized to do so, making it critical to both restrict and monitor who will be accessing the company's data through the cloud. In order to ensure the integrity of user authentication, companies need to be able to view data access logs and audit trails to verify that only authorized users are accessing the data. These access logs and audit trails additionally need to be secured and maintained for as long as the company needs or legal purposes require. As with all cloud computing security challenges, it's the responsibility of the customer to ensure that the cloud provider has taken all necessary security measures to protect the customer's data and access to that data.

Contingency Planning

With the cloud serving as a single centralized repository for a company's mission-critical data, the risks of having that data compromised due to a data breach or temporarily made unavailable due to a natural disaster are real concerns. Much of the liability for the disruption of data in a cloud ultimately rests with the company whose mission-critical operations depend on that data, although liability can and should be negotiated in a contract with the services provider prior to commitment. A comprehensive security assessment from a neutral third-party is strongly recommended as well.

Companies need to know how their data is being secured and what measures the service provider will be taking to ensure the integrity and availability of that data should the unexpected occur. Additionally, companies should also have contingency plans in place in the event their cloud provider fails or goes bankrupt. Can the data be easily retrieved and migrated to a new service provider or to a non-cloud strategy if this happens? And what happens to the data and the ability to access that data if the provider gets acquired by another company?
