We must incorporate best practices for risk management in cloud computing to maximize its benefits and keep the risks and threats under control.

Drawbacks of Cloud Computing

Vulnerability to attacks

One prominent and most common cloud computing threat is data theft, as the company stores all critical data online in the cloud database. Unfortunately, a data breach is something even large organizations with a full-proof security system are unable to prevent. Although advanced security protocols are followed on the cloud, confidential data stored there is always vulnerable to cyberattacks from any corner of the world. 

Network connectivity dependency

Network connectivity in cloud computing is crucial for reaping its benefits. This direct correlation means that any company that shifts entirely to cloud computing needs to have a fast and reliable internet connection to maximize the benefits of cloud computing. Even remote working is not possible without good internet to connect at the employee end, making network connectivity dependency a major limitation of cloud computing.

Downtime

Downtime is regarded as the biggest cloud computing risk of using cloud computing. The public cloud providers may face technical issues at times due to various reasons like natural disasters, power outages, low Internet connectivity, breakdown of data, etc. This can lead to a temporary or more extended downtime on the cloud platforms, depending on the severity of the technical issues. 

Vendor lock-in

When there is a need to migrate from one cloud computing platform to another, an enterprise might face serious issues due to the differences between the two platforms. For example, when running applications and storing data from the previous cloud platform when migrating to a different one, there might be support issues and configuration complexities, and it may require modifications in the applications that can lead to additional expenses. In addition, cloud computing vulnerabilities can’t be ruled out when there is migration, and companies must take necessary precautions for the smooth transfer of applications and data to the current cloud platform.

Limited control

Cloud users might need to cope with limited control over their deployments. Cloud applications run on remote servers and are owned and managed by the service providers. This makes it challenging for enterprises to get sufficient control so that they can make changes to back-end infrastructure as and when needed.

Security and Privacy

Although cloud providers deploy the best security systems adhering to industry standards, storing critical data on third-party servers is one of the major security risks of cloud computing. Any protocol building involving data must consider security and privacy, especially when handling sensitive data. As these are constantly accessed remotely, there are chances of a data breach or some malware being used to corrupt the data. As a result, security concerns in cloud computing are always the deciding factor when it comes to choosing a third-party cloud service provider for any company.

Best Practices to Avoid These Risks

Cloud security includes all types of processes and applications that ensure an enterprise’s cloud infrastructure is protected against both internal and external cloud computing threats. As more enterprises are looking to shift their entire operations to the cloud, security becomes the number one priority to make it sustainable for a long time.

Cloud security is always evolving, but some of the best practices still remain the same, ensuring that cloud computing risks are prevented or mitigated as soon as they appear. Enterprises that are currently working on a cloud platform or planning to deploy one must follow the below best practices for minimizing the security risks of cloud computing are,

  • Have a clear understanding of your shared responsibility model
  • Ask detailed security questions and get clear answers from your cloud provider
  • Implement an access and identity management solution
  • Offer thorough training to your employees on using the cloud platforms
  • Develop & enforce cloud security policies
  • Ensure endpoints are secured
  • Encrypt data both at rest and in motion
  • Utilize intrusion detection & prevention technology
  • Thoroughly check your compliance requirements
  • Carry out audits & penetration testing
  • Create security logs

Conclusion

Although there are limitations to cloud computing, like every other technology in the world, the benefits outweigh the risks, making it a necessity both now and in the future. The trick is to follow the best and most proven strategies for risk management in cloud computing and maximize the benefits that can take your enterprise to new heights in terms of customer service and revenue growth. 

As we know, cloud computing is evolving, and with that, the complexities of the threats and vulnerabilities will also increase simultaneously. But if we manage to detect and mitigate cloud computing threats through best practices and advanced security systems, we can leverage the benefits of cloud computing and optimize each and every business operation, leading to higher productivity, better service delivery, and the creation of more revenue streams along the way. 

The advantages and disadvantages of cloud computing make it dynamic and exciting at the same time, but with the right approach, the limitations can be turned into solutions that will help make cloud technology more efficient and relevant.
