Understanding Data
Before preparing for your cloud migration, you must make sure you have a thorough understanding of your data and its requirements. This means that the migration team must have a deep understanding of current and future data usage and understand the storage and retention policies in the company's data governance framework. You can use various cloud management tools, for example, deduplication software, to handle data understanding and optimization tasks. These tools can help you identify and process redundant data and improve storage efficiency. At the same time, it is also very important to protect cloud data. As a result, you must have an accurate understanding of what cloud data is and how it is ultimately used and processed. This includes identifying what data is sensitive. Additional security measures are required to ensure that data privacy and compliance requirements are met. Understanding Data Compliance Requirements
In addition to understanding the data itself, businesses must understand any compliance requirements that apply to their data sets during cloud migration. For example, regulatory frameworks such as GDPR, PCI-DSS, and HIPAA impose stringent requirements on many businesses, including removing personally identifiable information before data migration. Therefore, businesses must ensure that the selected cloud infrastructure provider meets compliance requirements while strengthening API security controls and taking steps to de-identify or remove personally identifiable information to protect user privacy. In addition, user access privilege must be properly managed to restrict access to data. These measures help ensure data compliance and security during cloud migration.
Data Encryption During Transmission
Data transmission during cloud migration can introduce additional security vulnerabilities. One effective way to protect sensitive information is to use source-to-target encryption. This process is usually done by using an encryption protocol like Transport Layer Security (TLS). The protocol encrypts all data before it leaves the open-source system and decrypts the data once it reaches the target system, adding an extra layer of security. There are a variety of encryption algorithms to choose from depending on the level of protection you need, though modern industry standards such as AES or RSA are used in most cases.
Companies should also ensure that encryption keys and credentials needed for access are securely stored and backed up regularly to prevent data loss. A cloud service provider can simplify this process by offering built-in encryption services. Companies should still conduct due diligence to ensure they have the proper tools and security measures in place before starting a migration.
