As a general statement, cloud storage of any type is a more secure option than on-site storage for most businesses. On-site storage is at risk for theft of the server, server failure, or damage to the server through fire, flood, or other types of potential physical damage.
Physical Security Issues
Cloud storage means the data and software applications are not housed on-site. Data is also not stored on just one server. Instead, the cloud technology uses multiple secured servers and builds in redundancy. These servers are managed, which means all security updates are completed on a schedule, further reducing the chance of hackers taking advantage of any vulnerabilities.
At the same time, the secure data centers are protected with multiple layers from both external and internal access. These types of security measures are rarely in place with in-house servers. The security levels are developed through the data centers to comply with any HIPAA, financial and banking, or any other security requirements.
Types of Clouds
There are three basic types of clouds. These include public, private, and hybrid. All offer effective security solutions, including end-to-end encryption of data. The private cloud provides the user with the option to add security features. These features can accommodate any specific compliance issues or increase the security layers. These types of fully customizable clouds are the most secure and used for highly sensitive types of data storage and processing.
Hybrid clouds also offer the option to store data on either the public or the private side of the cloud. This is a very secure solution, with the company having complete control of security on the private side of the hybrid cloud.
