Cloud adoption continues to accelerate as organizations seek greater flexibility, cost savings, and scalability. However, storing data in public cloud platforms introduces unique security challenges, especially for sensitive or regulated information. Understanding how to protect your organization’s data, and how encryption can help to address those challenges, empowers you to make informed decisions for your business.
Why Cloud Data Security Matters
When organizations migrate to the cloud, they gain significant advantages in data accessibility, collaboration, and resource efficiency.
Yet, these benefits come with potential risks that are important to recognize:
- Data Security and Confidentiality: Keeping your data secret can be at risk due to configuration mistakes or insufficient access controls that could inadvertently make sensitive data available to unauthorized parties.
Besides the aspect of Human Errors, public cloud services are also attractive targets for cybercriminals, given the vast quantities of data they store. Breaches can lead to data theft, ransomware incidents, misuse or disclosure of proprietary or sensitive information. - Data Sovereignty: As data is subject to the laws and governance structures of the country where it is collected, stored, or processed, cloud providers may need access to your data. For example, due to laws like the U.S. CLOUD Act, data stored on certain servers may be accessible to government authorities, even if the physical servers are located abroad.
- Compliance: Access to cloud-stored data through third-party might conflict with local laws regarding data protection and privacy. For example, the European Union's General Data Protection Regulation (GDPR) mandates strict rules for handling personal data within its member states. Non-compliant data handling can lead to hefty fines and reputational damage.
Awareness of these challenges is the first step in creating a secure cloud environment for your organization.
The Enabler for Cloud Data Security: Data Encryption
Data encryption is widely recognized as a foundational strategy for protecting sensitive information in the cloud. Encryption transforms readable data into coded information, which can only be decoded with the correct cryptographic keys. This process ensures that, even if an unauthorized party gains access, your data remains protected and unusable to them.
The top benefits of data encryption for cloud use cases are:
- Safeguarding data confidentiality, both at rest (when stored) and in transit (while being transmitted)
- Enhancing compliance with data protection regulations and industry standards as data is not stored in clear text in the cloud
- Reducing the impact of potential data breaches as the stolen data is indecipherable
- Lowering the risk of falling victim to a cyberattack as consequently encrypting data before upload to the cloud environment makes your organization unattractive as potential target to attackers
Best Practices: How to Encrypt Cloud-stored Data
To effectively protect your cloud-stored data, ensuring to seamlessly integrate your data encryption strategy without disrupting work routines, consider the following five crucial practices:
No 1 - Implement Client-Side Encryption
Encrypt data on your own devices before it even reaches the cloud, so only you hold the decryption keys and the data in the cloud is never unencrypted.
No 2 - Set Role and Group-Based Access Controls
Assign permissions based on specific job roles or groups. This limits data exposure to only those who truly need access to the data.
No 3 - Ensure a Seamless User Experience
Select an encryption solution that is intuitive and easy to use. A user-friendly system encourages consistent adoption, helping prevent errors and data breaches.
No 4 - Separate Duties between Network Administrators and Security Officers
Maintain clear distinctions so no single person has control over both data access and the encryption system, reducing risk of internal threats or external service providers.
Tip: Even if a cloud provider offers built-in encryption, this doesn’t mean your data is secure. Just if you are controlling your encryption keys, you can ensure security and autonomy.
