How to enhance cloud storage security is inevitable in line with rapidly-moving cloud usage to accommodate growing business necessity. Cloud storage keeps huge amount of data that benefit for their enterprise.

Google Cloud makes cloud storage among top priorities for improving service qualities for customers’ data in all of Google’s products. How to enhance cloud storage security assists for every enterprise’s requirement on growing storage, too. The Cloud Storage contains important features, such as Bucket Lock, Cloud Key Management Service (KMS) and Access Transparency. They take full responsibilities for keeping your data safe in Cloud Storage.

Given the high demand on updated cloud security, Google continues adding features that will improve the service. It completes cloud storage with V4 signature support, a critical multi-cloud security capability for customers and partners. V4 signature helps customers producing signed URLs with limited permissions and duration. They can issue this for their clients/users who don’t need to have a Google identity.

The second one is hash-based message authentication (HMAC) for the Cloud Storage service accounts. This can reinforce authentication and security without using credentials tied to the user accounts frequently.

The third one is uniform bucket-level access for Cloud Identity and Access Management (Cloud IAM). This helps you implementing policies by role to Cloud Storage users together with other Google Cloud products. In addition, the feature opens for manageable at scale for your cloud usage.

With the important elements, so how can you enhance cloud storage security?

1. Turn on uniform bucket-level access and its org policy

Upholding IAM policies can benefit you in some ways. The first one is applying an organizational policy that allows you implementing the use of uniform IAM access policies on all new buckets when necessary. At the bucket level, applying IAM policies can prevent inadvertent public exposure.

Financial service and technology are two industries that mostly take advantage from this policy. You can utilize the IAM for managing uniform permissions at scale. Typically, the situation sees many developers/employees need to access the data but it can’t be opened to external parties outside the company.

2. Activate domain-restricted sharing

The second tip helps you preventing unintentional public data sharing or sharing beyond your organization. The feature can assist organizations and development teams moving quickly while security and governance teams can enforce security at scale and trust that resources have the right controls in place.

3. Encrypt your Cloud Storage data with Cloud KMS

Cloud KMS refers to a cloud-hosted key management service supported by Cloud Storage that offers you organizing encryption keys for your cloud storage data. This encryption helps for many companies collecting, storing and processing personal information.

4. Apply Cloud Audit Logging for Cloud Storage Data Audit

Cloud Audit Logs makes visible user activity and data access across Google Cloud, including Cloud Storage. With Cloud Audit Logs, your Cloud Storage can turn into a secure, immutable and highly durable audit trail.

5. Deploy VPC Service Controls for Securing Your Data

VPC Service Controls can allow you configuring security perimeters around the resources of your Cloud Storage service and control exfiltration of data across the perimeter boundary.
