A Cloud Services Security Analysis

The aim of the article is the analysis of cloud services and data stored into cloud infrastructure. At first, history and principles of cloud computing technology are introduced. This is flowed by the introduction of security threats related to the use of cloud computing technology for storing data into cloud infrastructure managed by a third-party subject, whose infrastructure is different from that of the owner of the stored data. Based on the identification of security threat identification, tools designated for encryption of data saved into cloud, and allowing for increased security and mitigation of threats related to cloud data storing are showcased. Furthermore, these tools are compared using a comparative analysis in terms of workload on system and network adapter resources while encrypting and storing the data into cloud. As part of the comparative analysis, a comparison of encryption and saving of a single 1-GB file and 10,000 .txt files was performed. In the last part of the article, the results of the comparative analysis are interpreted visually and with the description of the measured values.
