Is the cloud service provider responsible for cloud data security?
The responsibility for securing cloud data lies with the cloud service provider and yourself. It is a joint effort. Of course, you can count on the security of your supplier to be of the highest level. For example, Microsoft and Amazon have developed identification management tools themselves. This ensures that only the right people can access sensitive data.
Always be aware that the cloud service provider has the correct security certifications. They demonstrate how the supplier has safeguarded the security of customer data.
What security measures should I take myself?
You can take various measures to provide extra security for data. Backing up is a very important precaution. Any loss of data can cause many problems. In the unlikely event that this happens with your cloud provider, it will help enormously if you have a backup of all data at a different location. This considerably reduces the chance of operational problems due to the hack.
Encrypting data is also a must when it comes to precautions. This during transport to the cloud and storage in the cloud. This reduces the chance that a hacker can actually cause damage to the data he has stolen.
Using a strong password policy – preferably via two-factor authentication – is highly recommended. As well as installing a high-quality antivirus program.
Can I just store all company data in the cloud?
There are two important things to keep in mind when storing data in the cloud. Protect your data with regard to points: confidentiality, integrity, and availability. By classifying data, you determine which data is and which is not stored in the cloud.

The second point of attention is the storage location. Once you have decided to store data in a cloud, you need to know where exactly the data is. Especially when it comes to privacy-sensitive information. This means that you don’t just store data on a public cloud server in America, for example. Major suppliers such as Microsoft are approaching you with so-called ‘regions’. They offer customers a guarantee that their data is stored in a data center in their vicinity so that it is compliant with the laws and regulations that you deal with.
Why is investing extra energy in cloud security a must?
As a rule, the cloud offers organizations a lot of conveniences and also a cost advantage. On the other hand, with your choice of a public cloud, you can lose sight and control of the company data. If your data is stored in a multi-tenant environment – where multiple customers use the same server – then you want to make sure that no one can access that data just like that.
Since the introduction of GDPR, it is regularly reported that data is on the street due to vulnerabilities in systems, or lack of clarity about responsibilities. The risks are high: high fines and reputational damage.
It is advisable to first check which cloud best suits the data you want to store there. Be well informed about the access controls that a supplier uses and how the systems are protected against vulnerabilities and malicious parties.
Is it also wise to store your data in the cloud?
The cloud offers many advantages. Also with regard to data storage. Make the switch to the cloud with policy. Arrange the most important security matters in advance and properly trim a number of possible vulnerabilities or leaks. That may seem obvious, but the practice is often more unruly. Either way, make security a top priority if you’re considering migrating to the cloud.

Involve your IT team in-migration from the outset. They have the knowledge to properly assess any risks. Do not make your transition to the cloud more difficult for yourself than necessary. Pay attention to how data is now secured on-site and which controls and measures are necessary for adequate data security and access control. Then see how this approach can also be used in a cloud environment. So that your data is in good hands there too.
