security issues in cloud computing
In the last few years, cloud computing has grown from being a promising business concept to one of the fastest growing segments of the IT industry. Now, recession-hit companies are increasingly realising that simply by tapping into the cloud they can gain fast access to best-of-breed business applications or drastically boost their infrastructure resources, all at negligible cost.
In the last few years, cloud computing has grown from being a promising business concept to one of the fastest growing segments of the IT industry. Now, recession-hit companies are increasingly realising that simply by tapping into the cloud they can gain fast access to best-of-breed business applications or drastically boost their infrastructure resources, all at negligible cost. But as more and more information on individuals and companies is placed in the cloud, concerns are beginning to grow about just how safe an environment it is.
SaaS (software as a service) and PaaS (platform as a service) providers all trumpet the robustness of their systems, often claiming that security in the cloud is tighter than in most enterprises. But the simple fact is that every security system that has ever been breached was once thought infallible.
Cloud service users need to be vigilant in understanding the risks of data breaches in this new environment.
For their part, companies need to be vigilant, for instance about how passwords are assigned, protected and changed. Cloud service providers typically work with numbers of third parties, and customers are advised to gain information about those companies which could potentially access their data.
As with most SaaS offerings, the applications forming SmartClear's offering are constantly being tweaked and revised, a fact which raises more security issues for customers. Companies need to know, for instance, whether a software change might actually alter its security settings.
Possibly even more pressing an issue than standards in this new frontier is the emerging question of jurisdiction. Data that might be secure in one country may not be secure in another. In many cases though, users of cloud services don't know where their information is held. Currently in the process of trying to harmonise the data laws of its member states, the EU favours very strict protection of privacy, while in America laws such as the US Patriot Act invest government and other agencies with virtually limitless powers to access information including that belonging to companies.
While the cloud may be flexible and cost-efficient, a lack of data safeguards and compliance standards makes security the largest hurdle to leap.
Security concerns relate to risk areas such as external data storage, dependency on the “public” internet, lack of control, multi-tenancy and integration with internal security. Compared to traditional technologies, the cloud has many specific features, such as its large scale and the fact that resources belonging to cloud providers are completely distributed, heterogeneous and totally virtualized. Traditional security mechanisms such as identity, authentication, and authorization are no longer enough for clouds in their current form. Security controls in Cloud Computing are, for the most part, no different than security controls in any IT environment. However, because of the cloud service models employed, the operational models, and the technologies used to enable cloud services, Cloud Computing may present different risks to an organization than traditional IT solutions. Unfortunately, integrating security into these solutions is often perceived as making them more rigid.
