Every business strives to protect the information in its cloud storage – this applies to small and giant companies. In the article, you will find information about the most effective methods of information protection.
Encryption
Encryption is one of the best ways to secure cloud systems. Here are the different encryption options that both a cloud service provider and a third-party cloud security provider can offer.
- Encryption of all messages in the cloud.
- Encryption of highly sensitive data such as credentials.
- End-to-end encryption of all data uploaded to the cloud.
Data is most at risk of being intercepted while moving—from one store to another or from the cloud to your on-premise application. Thus, end-to-end encryption is the best way to guarantee critical data security in the cloud: without a key, outsiders will never be able to read your messages.
Configuration
Configuration is another powerful tool in the cloud security arsenal. Often a cloud is hacked due to such an elementary vulnerability as a configuration error. Eliminate such mistakes, and the cloud data leakage risk will be much less. If you do not understand the intricacies of settings, use the services of specialists in this field.
Cloud storage and file sharing
Cloud security risks affect everyone, both businesses, and individuals. For example, the public cloud can store and back up files (for instance, to Dropbox), access email and office applications, and prepare tax returns and other documents.
You should consider how you will share cloud data with others, especially if you are a consultant or freelancer, for example. Sharing files on Google Drive or a similar cloud service is a convenient way to send completed work to clients, but you need to set permissions correctly. After all, you don’t want different clients seeing each other’s names or folders or making changes to other people’s files.
Check the security level of your cloud service provider
Security should be one of the key criteria when choosing a cloud service provider. Your cyber security is no longer just your concern – the supplier must do its part by creating a secure cloud environment and sharing responsibility for data security.
For hybrid clouds
Unfortunately, cloud service providers won’t provide a complete diagram of their network’s security. It’s like asking the bank to give you a plan of their vault along with safe codes.
Service segmentation allows an organization to control data storage and access. For example, you can create multiple layers of security by uploading key data, applications, and processes to the cloud and leaving the most sensitive information under local control. In addition, data segregation will help an organization comply with data protection regulations.
Redundancy is another benefit of hybrid clouds. You can move your day-to-day activities to the public cloud and back up your systems on local servers. This way, work will continue even if the connection to one of the data centers is lost or it is infected with ransomware.
