Cloud Migration: How to Ensure Data Security When Moving to the Cloud?


When working with sensitive information, data security should be the topmost priority. But, How can you ensure data security when migrating your data to the cloud?

Even if you are confident in the security of your on-premise security and the security of your cloud service provider, cloud migration has its own set of issues. Data flow must be encrypted, system components must be isolated, and permissions must be double-checked. Your business can ensure that its cloud data security is maintained throughout the process by following a step-by-step process for cloud migration security.

What are the Benefits of Cloud Migration?

The benefits of migrating to cloud services are numerous. Some of these, to mention a few, are:

  • Minimal upfront costs: Because no hardware is required, the initial cost of using cloud services is lower.
  • Easy scalability: Using the cloud, scaling services up and down based on relative demand is simple. It also implies that you only pay for what you use, resulting in cost savings.
  • Easy Maintenance: When compared to on-premise, using the cloud implies your engineers will have to undertake less maintenance. This frees up time for your team to upgrade and develop new applications.

Is data in the cloud secure?

Even though cloud services provide security features, many users are concerned about the number of people who may access their cloud with the appropriate permissions. Cloud services, such as AWS, however, must meet a variety of security criteria. These are available at AWS Artifact.

How is data kept safe?

To maintain the security of cloud data and traffic, encryption is often used. This entails scrambling a file’s data, rendering it illegible to anyone who does not possess the data encryption key. Only those with the correct data encryption keys will be able to access your information.

An internal network also carries traffic between cloud services. This implies that your team’s traffic should be private and unaffected by outside influences.

Multiple cloud accounts enable your company to separate various environments. This implies that your employees will only have access to the resources associated with their account that are relevant to them.

How to Ensure Your Data Secure in the Cloud?

Data integrity is a critical aspect of cloud data security, as it prevents illegal alteration or deletion and ensures that data stays as it was when it was first uploaded. The following are the top threats to cloud data integrity:

  • Human errors
  • Insider threats
  • Malicious intruders
  • Compromised hardware
  • Transfer errors
  • Configuration error

Provable data possession (PDP) and high-availability and integrity layer (HAIL) are two approaches that can help ensure data integrity in cloud storage (HAIL). Many cloud security management solutions compare the current state of cloud data to the last known good data state regularly and alert admins if there is a mismatch.

Data integrity also necessitates access control and the least privileged approach. File sharing among untrusted tenants puts virtual storage solutions at risk. As a result, before migrating sensitive data to the cloud, building a tight data access control is critical. Another essential practice is monitoring user activity, failed access attempts, file alterations, and unusual efforts to gain critical business data.

How Can You Ensure Data Confidentiality in the Cloud?

Preserving data confidentiality is essential for maintaining customer trust and complying with regulatory regulations. The high-profile data security breaches that are in the news all the time illustrate the tremendous cost of data security concerns. 

  • For example, national and international guidelines such as the Payment Card Industry Data Security Standard (PCI DSS), the Health Insurance Portability and Accountability Act (HIPAA), and the General Data Protection Regulation (GDPR) require organisations to ensure the security and privacy of various types of sensitive information and impose severe penalties for failure.
  • Make use of data masking. This strategy involves masking sensitive information with characters or other data. Data can be concealed in its original place or when a user or application requests it in real-time. 

Encryption is one of the most prevalent and safe data masking strategies, as it prevents unwanted parties from viewing or understanding stored or exchanged data. Asymmetric encryption employs one public key and one private key, whereas symmetric encryption uses only one private key for encryption and decryption. Encryption key management is crucial; in particular, policies must be established to ensure that only trusted individuals access them. Preventing prying eyes from accessing your protected data is possible with cloud encryption solutions.

How do you make sure your data is always available in the cloud?

One of the key advantages of moving to the cloud is that data is accessible from anywhere with an internet connection. Furthermore, cloud services might help you prevent onsite device and server failures and outages. Furthermore, cloud computing’s data redundancy gives you peace of mind by ensuring that your data is backed up and protected against data loss.

However, you should thoroughly investigate how well your cloud service provider ensures client availability. Create a service level agreement (SLA) that ensures the availability you require.

Key Takeaways

When thinking about ways to improve your cloud computing data security, keep the following in mind:

  • Implement the least privilege model.
  • Audit activity across your environment.
  • Categorise your sensitive data.
  • Encryption and other data masking techniques can be used.
  • Check to see if your cloud provider has an SLA that matches your availability requirements.

These best practices in the cloud can help you maintain data integrity, confidentiality, and availability.

Keeping Your Data Safe While Migrating To The Cloud

Data security and migration to the cloud do not have to be complex. Following these best practices and pre-designed protocols are the most reliable and effortless approaches to achieving long-term success with technology and software. And it is true when it comes to the security of cloud data.
