How to Ensure Data Security During Cloud Migration

Security of data is generally one of the major concerns in the moving of an organization’s IT infrastructure, applications, and data to the cloud, by setting layers of robust security guarantees, data is kept safe along the chosen cloud path and allows it to comply with all needed industry regulations. Here are critical strategies that should be implemented to guarantee data safety during cloud migration:

• Encryption: Encryption is one of the best ways to ensure that data is safe during migration. Organizations must ensure their encryption for data in motion and data at rest, meaning data should be encrypted before it leaves the original environment while being carried over to the cloud and encrypted in the cloud environment where it remains stored. Most cloud services and platform providers can easily achieve data encryption; however, third-party enc­ryption tools can be used to ensure more stringent security.
• Compliance and Data Governance: Comply with the pertinent data protection laws and associated industry regulations, such as GDPR, HIPAA, or PCI DSS—whichever is relevant; data compliance does not only involve data security but also the documentation of data access, recordkeeping, and the process of data processing to be completed in line with regulatory requirements. One should work very closely with the legal and compliance team so that all aspects and details of the migration meet the regulatory requirements.
• Access Control: Strong access control measures limiting the maximum number of people who could have specific access to the critical data being migrated are a must. Related authorized personnel can also access or manipulate data using role-based access control. Multi-factor authentication adds a layer of access control, where users’ identities are authenticated through various devices before they gain entry.
• Data Loss Prevention: DLP tools protect sensitive data from being lost, stolen, or even inadvertently shared during the migration process. These tools monitor and control the data stream to ensure no leakage or exposure of sensitive information during the migration process. Some DLP solutions may be integrated with cloud platforms to protect before, during, and after migration continuously.
• Backup and Recovery: Organizations need to back up all of their data and keep it secure before commencing the migration process. This ensures that, in the event of failure, the data can be restored easily without much loss. Moreover, a good disaster recovery plan will ensure that the data is recovered much faster in case a data loss or security incident ensues during the migration process.
• Continuous Monitoring: Security doesn’t end when everything is migrated. A continuous monitoring practice for the potential detection and response to any suspected security threat to the organization’s cloud environment is in order. This includes periodical security audits, vulnerability assessments, and real-time network traffic and user activities monitoring.

Critical Strategies to Ensure Data Security During Cloud Migration

By following these best practices, organizations can mitigate the risks associated with cloud migration and ensure that their data remains secure. For organizations looking to balance on-premises and cloud environments, a Hybrid Cloud Migration Strategy may be the best approach.
