When storing data in cloud storage, enterprises need to be aware of various security concerns. One of the most common concerns is unauthorized third-party access to files. While this is a well-known risk, many organizations fail to address it. To address this concern, organizations must implement measures that limit access. These measures include establishing permissions that follow the principle of least privilege and logging all file access. Here are some important things that you should keep in mind before storing data in the cloud.
Ensure that your cloud service has appropriate security controls:
The most effective way to protect against these attacks is to ensure that your cloud service has appropriate security controls in place. For example, use a Web Application Firewall (WAF), share important resources with administrators, and perform regular security audits. In addition to outsider threats, malicious insiders are also a significant risk. While this threat can be mitigated, it can magnify security risks. For this reason, it is important to store encryption keys on-site.
The costs of storing data in cloud storage vary, depending on the tier selected. Typically, storage costs are expressed in terms of price per gigabyte per month, or terabyte per month, with a variety of tiers available from different cloud providers. Typically, the cost for storage operations is minimal but can add up over time, especially for workloads with high object counts.
When storing data in the cloud, you will need to take several precautions to keep your data safe. First, it is important to read the user agreement carefully and make sure that the cloud provider has a SSAE 16 or SAS 70 audited data center. Next, you should check whether the data center is PCI or HIPAA-certified. These measures are important if you have sensitive information that needs to be protected.
While cloud storage is a great backup option and provides easy access to your data, you should consider the risks associated with this method. Ensure that you encrypt your data and check the institute’s policies and procedures before putting sensitive data in the cloud. There are also some risks involved in data loss, such as a data breach.
Object life cycle management:
Cloud storage providers often offer Object Lifecycle Management as an option. With this feature, you can configure a rule that lets you determine when to delete objects, downgrade storage classes, or retain non-current versions. For example, if you need to keep a file for future backup plans, you can save it as a default and then remove it whenever necessary.
