Modern businesses use the cloud to share information in the blink of an eye. Co-workers share files, server space, and even workstations, while consumers share credit card and bank account information, as well as spending habits and purchase preferences.
When all this information is shared or stored within an organization, it can wind up in the wrong hands if staff don’t really understand data security. But, on the other hand, locking down employee access to information can prevent them from carrying out their work. Those in leadership positions must find some middle ground that protects company and client data, while still enabling staff to do their jobs unhindered.
This requires finding and fixing the weak spots in your security architecture. Third-party cloud cybersecurity firms often provide data security at less cost than hiring your own defense team. Sentek Cyber can determine how secure your existing cloud processes and protocols are with a vulnerability assessment.
A vulnerability assessment can identify the security holes in your digital infrastructure, both onsite and within the cloud. Vulnerability assessment experts are then be able to provide your company with ways to resolve or mitigate these issues.
There are several different security risks specialists will be looking out for when carrying out a vulnerability assessment on your company’s cloud-based infrastructure. They include:
Because of the open design of the cloud, multiple users (ie., companies) share the same resources. This runs the risk of other “tenants” seeing private data, or even being able to assume another tenant’s identity. Furthermore, computing space is recycled. That means an entity assigned “new” computing space may run across a former tenant’s data if it wasn’t properly destroyed. This could be particularly risky if you had previously stored sensitive information in the cloud.
The password remains the first line of defense in data security. Most people simply find it impossible to use dozens of unique passwords for all of their user accounts and stick with a small rotating list. But two-tiered access and processes that compel regular password updates add a layer of encryption. This can help prevent account hijacking, and protect sensitive and valuable data within the cloud.
Cloud service users at your company have no control over redundancy and fault tolerance. Denials of service, equipment failures, and power failures can all affect your company’s access to its data. Users must also assume responsibility for retaining encryption keys to unlock encrypted data uploaded to the cloud service.
Virtualization, which is used by all major cloud providers, brings with it additional concerns of host and user targeting. This can take the form of exploit risks that are host-only, host to guest, guest to host, or guest to guest.
To make matters more difficult, most cloud users are unaware of which virtualization tools their provider is using. And this isn’t the only time when it counts to know more about your company’s cloud provider.
It’s always important to read user agreements carefully. If you upload data to your company’s cloud service for storage and use, you may be transferring the ownership of your data to your provider. Ownership clauses enable cloud services to mine subscriber data to ensure more legal protection, to create new opportunities for business, and even to sell the data in the event that they go out of business.
A More Secure Future
Cloud computing may now seem like a risky move, but it is actually one of the safest and most effective ways of saving your company’s data – you just have to understand the service you’re using and its potential weaknesses.
