Security in a Cloud based Network

Cloud computing is an evolving technology that utilizes computer resources to deliver services over the internet.

 The services provided are many, and the users vary from individuals to multinational corporations. These users expect their data to be safe from unauthorized entry, complex breaches, and unwanted observers. Cloud computing has three methods to remedy the previously described issues – identity management, application security, and information privacy – which need to be provided, or you might lose these users to your competitor!

As we all know there is a need for security at every level. Be it the nation or a single human being there isn’t any guarantee that they would not face a sudden mishap, an unwanted loss or a unwelcome danger. The United Nations study of 1986 defines national security, as a crucial factor that has always been adding to the growth and prosperity of a particular country.

Security is not always an individual aspect. There are certain things that are supposed to be taken into consideration with it. These aspects are continuity, reliability and safety. There is a thin line of difference between security and reliability. The former actually deals with stopping people who intend anything wrong, from causing any issue.

Identity Management
An identity management system prevents unauthorized entry by taking care of authentication, roles, and privileges within the entity. Today there are many different methods to achieve this. The availability of these methods is dependent on the firm where the identity management system is purchased. The features of these methods are provided.

Access Control. This method consists of role-based access control. Here roles are given to users depending on their needs. A user may not need access to the whole system to perform their duties, and this feature provides lessened risk by restricting what is provided. And an added benefit, permissions do not have to be assigned directly which reduces work for the network administrator.

Password Synchronization. The user may need to log in to their account at a different computer in their companies’ network. Normally, the users’ credentials would not be accepted and the network administrator would need to setup their account on this and possibly every other computer. To avoid this situation, password synchronization allows the user to keep a single password across many systems. If a password is lost opening up a potential security breach, it can be changed right away on all systems across the network.

Application Security

The applications provided to customers must be free of vulnerabilities. Countermeasures, also called security updates, must be applied to fix potential loopholes. Vulnerabilities can be found ahead of time by testing the applications. Testing can be done by automated software called penetration tools or by having personnel review the code.

Information Privacy

Data stored on the cloud network can be altered to enhance privacy. If an outsider does gain access to the data, they will not be able to use the data since it is not the original. There are different ways to accomplish this.

Masking. This involves replacing parts of the data with false but real-like information.

Encryption. Data is scrambled using an algorithm. There are different security levels of algorithms depending on the need.

Shuffling. The original characters are moved around.

Nulling. Parts of the data are deleted.

Conclusion
Both ordinary users and large corporations expect a certain level of security. Following the methods above ensures a high level of data safety, and the assurance that your customers will remain.
