Cloud Computing Security
It is quite normal for a controversy on every new thing especially with the emergence of cloud computing which is such a tremendous revolution. The only fear that still remain by those who are still reluctant to adopt it is about data security. Well, we can define the basic needs of security for the IT system:
- Physical Security. To secure the concrete equipment such as hardware from theft or disaster.
- Access Security. To secure the system from being accessed by intruders.
- Data Security. To secure the data not to be stolen or accessed by unauthorized users and physically secured also.
Physical Security.
When we talk about physical security then we are talking about securing the physical devices or hardware of your computer system. The physical security at data center of every cloud provider such as Microsoft, Google, Amazon, etc is very sophisticated and beyond compared with your local office security. You can watch the video below for some data center.
Access Security.
When we talk about access security, we are talking about controlling the access remotely through the internet connection to the system. Except your system is not connected to the internet then the vulnerability is the same. This security really depends on the software itself not on the location whether on cloud or on site.
Data Security.
Data Encryption is a proven technology to protect your data so that even if someone can access your data but he will not be able to read or understand it since the data is encrypted. The next question is then about backing up your data. The cloud provider will not only backup your data regularly but also replicating it to other locations as well. This will surely be more reliable since if an earthquake happen at your location like what just happened in japan then your data is safe because there are several copies stored at a far away locations even in another countries.
The conclusion is then it does not make sense if you doubt about migrating your system to the cloud because it is even much safer. I hope this short explanation can change your view and mindset about cloud computing.
