Open Source Cloud Security Tools can help organizations assess their infrastructures for vulnerabilities, misconfigurations, and other flaws which are known for potentially putting them at risk of data breaches. Many organizations deploy one or more open-source cloud security solutions in addition to performing data backup and perform integrity checks.

Open-source cloud security solutions are great for companies that have a limited budget but do not want to compromise on the quality of testing whilst being assured of great community support. Below we provide an overview of the best Open Source Cloud Security Tools in 2024 and what to watch out for when it comes to their advantages and limitations.

What is Cloud Security?

Cloud security is a collection of systems, applications, and technologies that govern the storage and transmission of data online and keep it safe. Cloud providers host these infrastructures on services and provide services to customers via subscriptions.

Cloud security is comprised of various components such as – identity and access management (IAM), regulatory compliance, threat response, risk mitigation, and digital asset management. 

What are Open Source Cloud Security Tools?

Open Source Cloud Security Tools are highly scalable, flexible, cost-effective, and efficient as they are not operated and maintained by a single organization. Open-source software is used in a wide range of cloud computing environments and backed by communities online, which assures their reliability and integrity. The main benefit of using open source cloud security tools is that they are designed with security in mind, unlike traditional cloud computing services.

Open-source cloud security software receives regular updates and is subject to peer reviews. They feature all-round availability and the source code can be viewed, modified, and edited by anyone. The cloud security open source community actively identifies potential vulnerabilities and gaps in these solutions as well and ensures that these programs stay up-to-date.

What are the Limitations of Open Source Cloud Security Tools?

Although open-source cloud security tools offers several benefits, they do not come without certain limitations. Following is a list of challenges users may experience when using them:

  1. Licensing complications – There are many open-source cloud security tools with different licensing and usage specifications. If the licensing criteria are not met, organizations may violate these licenses and risk getting sued or subjected to legal and financial repercussions. 
  2. Technical knowledge needed – Open-source cloud security tools are not beginner-friendly or intuitive in general. They require coding knowledge and technical acumen to operate effectively. Someone with no experience in cloud security practices may have difficulty using these solutions.
  3. Community-driven – Although community support is a great aspect of using open-source cloud security solutions, the downside is that sometimes it can be very limited. Being open source means that anyone can modify the code and affect platform and application performance.
  4. Misconfigurations through misuse – Open-source cloud security tools can introduce new misconfigurations and vulnerabilities through misuse. If organizations use outdated versions of open-source programs, they are at risk of having cloud accounts breached and will face cyber attacks.

Conclusion

Open-source cloud computing has been around for decades and it’s no surprise to see technological advancements in the cloud security domain catching up. We will expect to see major improvements made to Open Source Cloud Security Tools in the coming months and developers are constantly working on making the latest updates, bug fixes, and performance enhancements. If you are new to cloud security, trying out open source cloud security tools can be a great way to better understand security perspectives and make adjustments along the way for improving overall cloud security posture.
