Program Plan Intro

Cloud computing:

The term cloud can be defined as the process that led the computers resources to be accessed anytime anywhere over the internet. The cloud can be represented as the elastic leasing of the various computer resources that are known as the pooled resources that can be accessed over the internet.

Data security of cloud:

In cloud computing, users who put their information on the cloud, will be relived about storage and maintenance. Here, the data integrity is more challenging. Some of the challenges of data security measures that reduces threats in cloud computing are:

  • Confidentiality – Data is visible only to the legal or authorized users. The information cannot be accessed by third party.
  • Access controllability – It is nothing but the owner of the particular information can create selective restrictions for others to access data.
  • Integrity – It is nothing but maintaining information with exactness and wholeness of data. The information must be stored properly and it should not be damaged or modified illegally.
