Regardless of their size or sector of activity, many companies are choosing cloud services for the advantages they can offer: Flexibility, cost control, ease of use, ergonomics… However, these services are not so simple for CIOs to grasp, who must adapt their management and take into account new measures to control the associated risks.

What are the best practices to adopt to secure your cloud environment?
We guide you by highlighting 9 key points:
- The design of your environment: A cloud environment is by nature highly scalable! Therefore, from the outset, it must be designed in such a way that you can maintain a good level of security in the long term; ;
- Managing permissions and users: Just as in a traditional Active Directory environment, it is important to define an IAM strategy that adheres to security best practices, and in particular the principle of least privilege.
- Storage: Most cloud providers offer secure storage, encryption, redundancy, backup, and exposure control solutions for your databases and storage volumes: use them; ;
- Cryptography: Data and stream encryption is a particularly sensitive issue for French companies, as most providers are American and subject to the Cloud Act… Define an encryption and export strategy based on the level of confidentiality of your data; ;
- The network: You should view your cloud environment as an extension of your IT system and, as such, apply the same level of network security requirements as for your on-premises networks, particularly in terms of traffic filtering and exposure. Pay particular attention to interconnections with your local infrastructure, which create highly sought-after attack vectors!
- Logging: Beyond traditional logging (application, system, network…), implement a policy for logging access to your cloud environment, in order to be able to trigger an incident response under the best conditions in the event of a compromise; ;
- Surveillance: Use security metrics by leveraging the tools provided by cloud providers or your own SOC to identify potential malicious behavior and react quickly, or even automatically; ;
- Compliance: Formulate clear security requirements and control their effective implementation by configuring compliance tools, so as not to lose control of your growing environment!
As a bonus: The training: Every day brings dozens of new features… Suppliers are constantly adding new services, so train your employees continuously!
