Two cloud security myths
When it comes to cloud security, there are two main groups out there: those that believe that the cloud is systemically unsafe, and those that believe the cloud is unhackable. They are both wrong and cloud security isn't as black and white as some would have you believe.
With the proper planning, your data will likely be more safe in the cloud than in traditional systems. Remember that with all the data breaches that have been reported in the last few years, no cloud vendors have been involved. The reason is that the cloud providers are proactive and update their security constantly. Most traditional, on site systems have outdated security and tend to be reactive when it comes to security.
Just because your cloud vendor proactively take precautions doesn't mean that you don't have to do your part when it comes to security. Nothing is completely secure; less penetrable doesn't mean impenetrable. You need to be concerned with identity and access management (IAM), multifactor authentication and encryption. The biggest factors in cloud security are usually related to people: simple passwords, keeping passwords written down everywhere, and sharing same passwords for multiple accounts.
Cloud security depends on how much time and resources you spend planning out your cloud strategy. Cloud security is not an all or nothing approach.
