Security is the biggest concern for cloud users because they no longer have full control over the sensitive data stored and processed in the cloud.
Several major issues affect cloud security:
1. Data Lifecycle Management: Users cannot always be sure that their data is deleted properly. Even if the data is deleted, there’s no guarantee that the storage media will be wiped clean before being reused by someone else.
2. Unauthorized Access & Data Theft: Sensitive data in the cloud can be accessed by unauthorized people. Users are worried about data theft and attacks from insiders, such as rogue employees working for the cloud provider.
3. Lack of Standardization: There are no clear standards for data management and access during service interruptions, price hikes, or the cost of switching between cloud providers. This lack of consistency makes it difficult for users to know what to expect.
4. Legal Concerns: Laws regarding data security and privacy differ between countries. This creates confusion about which laws apply to the data stored in the cloud. Additionally, cloud providers may outsource services to third parties, adding more risks related to data protection.
Minimizing Security Risks
To minimize security risks:
- Evaluate CSP Policies: Check the cloud service provider’s (CSP) security policies and agreements to ensure they protect user data.
- Avoid Processing Sensitive Data: Whenever possible, avoid processing sensitive data in the cloud. If necessary, use firewalls or secure data access tools (like Google Secure Data Connector) to protect the data.
