Some security issues that you may have in cloud computing would be having your data on a server that other people may have access to, as well as the possibility that people could see your data if you're not sending it over an encrypted connection.



There's also the possibility of a server crashing and you losing all of your data if you don't have a backup stored somewhere else.



Another issue would be that a company may be forced to hand over any data that is stored on a server to law enforcement agencies if they are asked to.
