Why data security is important in Cloud computing

To run more agile businesses around the world, many are moving from self-hosted servers or data centers to Cloud computing. The Cloud offers improved data access, more applications and more efficient teamwork.

Security concerns with Cloud

Some data protection officers and privacy advocates are skeptical of the Cloud. They fear a lack of data security because the Cloud processes data from multiple parties, increasing the risk of cyberattacks. Furthermore, a lack of data residency and transparency of Cloud providers is often criticized. Data transfers abroad and the lack of control over the data processing infrastructure are also critical issues.

Data security is important in Cloud computing for the following reasons:

  • Confidentiality: Data stored in the Cloud may contain sensitive and confidential information such as personal data, financial information or intellectual property. Unauthorized access or security breaches can lead to loss of confidentiality and damage to a company/organization’s reputation.
  • Integrity: Ensuring the integrity of data is critical in Cloud computing. Data integrity ensures that data is not tampered with or altered in any way. This is essential to ensure the accuracy and reliability of data, especially for applications such as financial transactions or medical records.
  • Availability: Cloud computing depends on the availability of network connections and the reliability of cloud service providers such as AWS. Without proper security measures, Cloud computing could be vulnerable to attacks that could disrupt services and prevent access to personally identifiable information (PII).
  • Compliance: many industries are subject to government regulations, such as HIPAA for healthcare. Failure to comply with these regulations can result in significant penalties or legal action.


Data security in Cloud computing is critical to protect confidentiality, ensure data integrity, maintain availability and meet regulatory requirements. Appropriate contracts with Cloud providers such as a Transfer Impact Assessment (TIA) are appropriate ways to ensure data security in the Cloud.
