Security Issues in Cloud Computing IntroductionThe first ENIAC computer was invented by Charles Babbage in the 18th century. But the real technological progress of computers came with the invention of the first four-bit microprocessor in 1971. From 1971 to today, over these more than 40 years many operating systems have been created (such as Windows 95, Windows 98, Windows 2000, Windows NT, Windows XP, Windows 7, Fedora, Mac, Redhat, Ubuntu, Kubuntu, Solaris etc.), many programming languages ​​and web languages ​​were born (such as C, CPP, JAVA, .NET, HTML, SQL, PLSQL etc.) and many multinational companies were born (such as Wipro, Genpact, Apple, Google, Tech Mahindra, Xerox, Oracle, SUN, Adobe, Microsoft and many more). But the Internet is one of the keys to the growth of all of the above. Cloud Computing is an emerging concept in which computing infrastructure resources are provided over the Internet [1]. Cloud computing is a concept where every device is connected to the cloud that contains application, platform or infrastructure or a combination of them. People of the 21st century are more familiar with smartphones than anything else. With the advent of phones like iPhone and Android smartphones, the number of people using the cloud is increasing dramatically. Millions of people use the cloud in the current scenario and it is equally important to provide security to all users who use it. Cloud computing can be used as a tool to attract many people and make software as a service attractive [2]. There are several cloud security issues that can be discussed in this document.
