Benefits of cloud are almost zero upfront infrastructure investment, just-in-time infrastructure, more efficient resource utilization, usage-based costing and reduced time to market. There are several issues in cloud security as well. There are technology concerns like data location, data segregation, identity/federation, distributed storage, privileged user access and control concerns like compliance issues, legal, audits, visibility, change control and SLA. Security tops list of cloud challenges. Who is accessing my data? Can I enforce an effective access control policy? Can I present a trusted audit trail of all access events to my data? These are some of the questions which are always on the minds of cloud users. When you’re moving to the cloud, you need to see that how do you maintain ownership and control of your data in a multitenant environment? This is very important.
