Security risks in cloud computing

Cloud computing is the delivery and availability of on-demand services, such as servers, applications and data storage, that are hosted on a cloud service provider’s (CSP) platform instead of your own. This provides users with ease of access to resources across multiple devices. Beyond the capacity to host and store files and data, cloud computing provides access to resources, such as email applications, analytics tools and communication platforms. 

The accelerated growth of cloud computing is expected to continue to rise from $83.41 billion in 2022 to $376.37 billion by 2029. As more and more companies rely on cloud-based technology for their work, especially with remote working practices in place, you need to ensure that your deployment is secure so that data remains protected.

Having your files in an online space is not necessarily dangerous, but the convenience of cloud computing can lead to oversights in security. Businesses should be aware of the risks associated with storing data in the cloud. Here are some of the most common security pitfalls associated with cloud storage:

Data breaches

Unauthorized access brought on by inadequate security measures is one of the biggest threats to cloud security. As a business, you must consider if your CSP provider provides comprehensive protection against data leakage or unauthorized access.

Data loss

Cloud services have the potential to back up large amounts of data. However, cloud services are not infallible, so it’s important that your security strategy to account for potential data loss. Regularly backing up files and folders will help safeguard your company from data loss, so ensure your CSP offers this capability. 

Data leakage

Cloud services can provide publicly accessible links or URLs for uploading and downloading files. This may be practical, or even necessary, for your business operations, however if this is not managed correctly your company could be at risk of data leakage. Businesses should restrict access to links in accordance with best practices and encrypt data where appropriate.

Data deletion

Simply hitting the delete button when using most online storage solutions does not erase all traces of your backed up data. For example, Microsoft OneDrive keeps files in a cloud-based recycle bin even after they have been deleted locally. In order to ensure good data hygiene and meet compliance needs, it’s best to find out exactly how CSPs permanently remove old files from their servers, so there aren't any unexpected surprises down the line.  

Account hijacking

Cyber criminals can obtain valid login credentials to remotely access data stored in the cloud. This is why it’s best practice to enforce the use of strong, unique passwords, along with two-factor or multi-factor authentication, across your whole business. Additionally, the password security standards should be enforced as a company policy. 

Regulatory compliance

Data protection rules and regulations vary between territories. As part of your due diligence, ensure that prospective cloud providers deliver the data protection you need to maintain the security of your data and compliance relevant standards, such as the GDPR. If in doubt, consult with a DPO who can advise you on compliance and data sovereignty issues in the cloud.  

Insider threats

It’s not just external threats that you need to worry about. IT administrators, system developers, and other trusted employees with access to sensitive data could put your cloud security at risk. The larger your workforce gets, the greater the chance of an insider threat. So, businesses need a way of auditing activity taken on their accounts, such as monitoring when data is being downloaded or shared, the movement of files, and data deletion.
