The Elements of Public Cloud Computing Security

The Elements of Public Cloud Computing Security


Public cloud computing being the latest buzzword today, it is crucial to understand the factors that are essential for its smooth functioning. It primarily requires a security that reconciles scalability and multi-tenancy with the need for trust. Gradually, as organizations shift their computing platforms in addition their information, identities and infrastructure to the cloud, it is essential to let go of the control. However, prior to doing that it is crucial to verify the cloud events and procedures. The crucial building blocks of verification and reliable relationships comprise data safety, control, compliance and event management.

Key Elements of Public Cloud Security

Third party authentication services, ongoing identity management and federated identity are fast becoming the main components of cloud security. Identity security helps in conserving the confidentiality and integrity of applications and data, while making it readily accessible to the apt users. Hence the assistance for such identity management capabilities for infrastructure as well as other components is going to be a chief requirement for cloud computing. Furthermore, identity too needs to be managed in a way that it fosters trust.

In order to make this happen a strong authentication is required where cloud computing needs to shift beyond weak password and username authentication. This means resorting to those technologies that have been already standardized in the IT enterprises, for instance strong authentication, federation across and even within the enterprises, a risk based authentication that evaluates the behavior history. Present context and other factors to evaluate the risk level of a user request. Furthermore, additional layers of authentication too is needed to cater to the security service level agreements and making use of risk based authentication model that is completely transparent to users. This will further bring down the requirement for broader federation of access controls.

This apart, there is also need for information security solutions. In a conventional data center, the controls on physical access, access to software and hardware and identity controls are all merged to secure data. In a cloud platform, the protective shield that protects infrastructure is diffused. In order to compensate the security needs to be information centric. The data require its own security that moves it securing it across all networks. It is here that companies might think of considering network penetration testing solutions.

However, eminent cloud computing service providers will offer you a better way to expand your business and go public on cloud systems. These service providers have their own internet data centers that caters to all your IT needs and other infrastructure needs such collocation, dedicated and shared hosting services. Along with this they look into firewall and backup solutions enabling you to have a competitive edge over others.
