There was once a time when cloud security systems were very much able to tackle imminent threats through their inbuilt support systems. But, hackers have pushed forward, and it would appear that no data is secure from threats if additional security is not put in place. However, there are some handy precautions that you can take to safeguard your data from slipping into wrong hands. Read this article to learn more about best practices for maintaining and improving cloud security.
First and foremost, you must ensure that the encryption of data in transition is end-to-end. Third parties being able to look into data has turned out to be one of the primary sources of data breaches. Companies should conduct all interactions on servers over SSL transmission (TLS 1.2) to ensure optimum security. Also, the SSL should be programmed in such a way that it terminates only within the cloud service provider network.
Although it is necessary to encrypt data in transition, encrypting stored data is no less critical. Most of the data collected will happen to be sensitive in most companies. If you have that data, it becomes your responsibility — keeping stored data encrypted keeps it intact from the threats that come from within; this also helps you comply with privacy policies, regulatory principles, and obligations of your company vis-à-vis particular client or company as a whole. Generally, a cloud service provider provides field-level encryption where the customers get to specify the fields they want to be encrypted. However, AES-256 is an excellent tool for encrypting data on cloud disks as it also generates regularly rotated master key that helps keep the encryption keys safe.
User-Level Data Security
You must opt for role-based access control (RBAC) features through which you will be able to enable your customers to set user-specific access and grant specific permissions to their data. You must ensure that you are not defying any law; therefore, you cannot take non-granted looks into the user’s data. Thus, add protective layers to the data to meet compliance with data security standards.
You should rigorously use the vulnerability and incident response tools as provided by your service provider. Solutions from these incident response tools render automated security assessments which can test security threats and decrease the levels, and threat severity, in critical security audits. For better security, these tools should be used rigorously, almost on a daily basis. But, depending on the nature of your data, the assessment cycle can be readjusted, and auto cycles can be scheduled.
You must never leave data unattended. Data has its cycles of use, and if the cycle of one data set is complete and no further processing is required, that data should be deleted from the server. Review the deletion policy from your provider and make sure that your information is programmed to be removed at a pre-specified time as mentioned in your contract.
Another overarching measure for security enhancement is having proper compliance certifications — check what certifications your provider has. The two most essential certifications are PCI DSS, which signifies that the SaaS provider has undergone detailed audits that ensure secure storage and transmission of sensitive data, and SOC Type II, which tells that the internal risk management processes, regulatory compliance oversight, as well as vendor management programs are being carried out by the provider successfully.
Virtual Private Cloud
Having a private virtual cloud and network has its security advantages. In this scenario, you have entire control and access to your data and no other client. You don’t need to share the cloud with others, which inevitably results in increased security. The customer can securely connect to the corporate data, and all traffic in their VPC can be routed directly to their corporate data center.
These are some of the practices that must be incorporated for cloud security. The essential enhancer of cloud security is ultimately your service provider. So, make sure that you have one that’s trustable and experienced.
