cloud computing security concerns

The most significant challenge of Cloud is security. Gaining the trust of a large user base is critical for the future of cloud computing. It’s unrealistic to expect that a public cloud will provide a suitable environment for all applications. Highly sensitive applications related to critical infrastructure management, health-care applications and others will most likely be hosted by private clouds.

The most significant challenge of Cloud is security. Gaining the trust of a large user base is critical for the future of cloud computing. It’s unrealistic to expect that a public cloud will provide a suitable environment for all applications. Highly sensitive applications related to critical infrastructure management, health-care applications and others will most likely be hosted by private clouds.

Many real-time applications will probably still be confined to private clouds. Some applications may be best served by a hybrid cloud setup. Such applications could keep sensitive data on a private cloud and use a public cloud for some of the processing.

The Software as a Service (SaaS) model faces similar challenges as other online services required to protect private information, such as financial or health-care services. In this case, a user interacts with cloud services through a well-defined interface. In principle, therefore, it’s less challenging for the services provider to close some of the attack channels.

Still, such services are vulnerable to DoS attacks and malicious insiders. Data in storage is most vulnerable to attack, so devote special attention to protecting storage servers. The data replication necessary to ensure continuity of service in case of storage system failure increases vulnerability. Data encryption may protect data in storage, but eventually data must be decrypted for processing. Then it’s exposed to attack.

The Infrastructure as a Service (IaaS) model is by far the most challenging to defend against attacks. Indeed, an IaaS user has much more freedom than the other two cloud delivery models. An additional source of concern is that the considerable cloud resources could be used to initiate attacks against the network and the computing infrastructure.
