Cloud has become the central ingredient of enterprises’ digital transformation plans, courtesy COVID – 19 and resultant lockdowns. The mobility and ease of access of the cloud make it one of the most convenient choices. As more and more organizations are migrating their business-critical workloads and data to the cloud, ensuring data security in the cloud has become more critical than ever.
According to a survey by Ermetic, nearly 80% of businesses have experienced at least one cloud data breach in the last 18 months, while 43% of businesses reported more than 10 breaches. This trend will continue if companies do not improve their data protection strategies for the cloud.
Here are the top measures that companies can take to ensure data protection in the cloud:
Understand what data needs to be moved to the cloud – More often, it is found that not all data requires to be moved to the cloud. Enterprises unnecessarily hold on to the data that is outdated and is serving no purpose. There is no point in moving such data to the cloud. Hence, the first step in the data migration process should be to comprehend two things – the kind of data that is available and out of this, what kind of data can benefit from a migration exercise.
Setup Backup and Recovery Options – Although the technology today is extremely advanced, there are still environmental or technical factors that could result in loss of data, whether during or post migration to the cloud. Hence, it becomes extremely important to back up data as losing critical organizational data can not only result in huge financial losses but also reputation loss.
Always encrypt the data while migrating to the cloud – Encrypting data during transit means protecting data as it moves from one location to another. Data in transit is more lucrative for hackers to abuse than its counterpart – data at rest. If there are security loopholes while the data is being moved from one source to another, it becomes an easy target and results in huge financial and reputation loss for businesses. Cloud service providers generally offer encrypted network protocols along with network security control to ensure secure migration of data.
Ensure constant monitoring of data – The responsibility of ensuring data security does not get over with the migration process is a continuous process. Hence, it is advisable to make use of the tools available for managing cloud environments, detecting threats, and mitigating risks. Many cloud service providers offer Security Information and Event Management (SIEM) solutions. SIEMs enable businesses to centralize alerts and logging, and often incorporate analytics, machine learning, and automation to fast-track the detection and response processes.
In conclusion, safeguarding data in the cloud is more of consumers’ responsibility than the cloud service providers. Hence, consumers are required to make use of all the security avenues available to them – be it utilizing the security tools provided by the cloud service providers or establishing stringent cybersecurity guidelines across the organization or training their personnel in security best practices. Cloud consumers need to undertake all precautionary measures to eliminate any possibility of theft or loss of data.
