Open-source Platforms
Open source refers to a software program or platform with source code that is readily accessible and which can be modified or enhanced by anyone. Open-source access grants users of an application permission to fix broken links, enhance the design, or improve the original code. Open-source software (OSS) hubs, such as GitHub, are an example of a kind of open collaboration that can broaden design perspectives far more than a single company or design work group. Open-source practices can also lead to considerable savings, with many open-source offerings provided to consumers for free, relying instead on a shareware or donation model.
The idea of making source code freely available originated in 1983 from an ideological movement informally founded by Richard Stallman, a programmer at MIT. Stallman believed that software should be accessible to programmers so they could modify it as they wished, with the goal of understanding it, learning about it, and improving it. Stallman began releasing free code under his own license, called the GNU Public License. This new approach and ideology surrounding software creation took hold and eventually led to the formation of the Open-Source Initiative in 1998.
What is the Open-Source Initiative?
The Open-Source Initiative (OSI) was created to promote and protect open-source software and communities. In short, the OSI acts as a central informational and governing repository of open-source software. It provides rules and guidelines for how to use and interact with OSS, as well as providing code licensing information, support, definitions, and general community collaboration to help make the use and treatment of open source understandable and ethical.
Open-source code is usually stored in a public repository and shared publicly. Anyone can access the repository to use the code independently or contribute improvements to the design and functionality of the overall project. OSS usually comes with a distribution license.
When source code is changed, OSS must include what was altered as well as the methods involved. Depending on the license terms, the software resulting from these modifications may or may not be required to be made available for free.
What are some examples of OSS?
- GNU/Linux
- Mozilla Firefox
- VLC Media Player
- SugarCRM
- GIMP
- VNC
- Apache Web Server
- LibreOffice
- jQuery
Is OSS bug-free?
The short answer is no. With multiple parties making modifications and improvements, it’s inevitable that open-source software will contain quality, performance, and security flaws. However, the broad base of code contributors can also mean that bugs are identified and fixed faster.
No matter the type of software—open source or commercial—code flaws will exist. The main difference is who is responsible for fixing the bugs; for commercial software, vendors are responsible, whereas the consumer is responsible for open-source software. With a robust set of AppSec tools and practices in place, OSS can be easily secured.
What are the differences between open-source and closed-source software?
| Factors | Open Source | Closed Source |
| Price | Available for nominal or zero licensing and usage charges. | Cost varies based upon the scale of the software. |
| Freedom to customize | Completely customizable but depends on the open-source license. Requires in-house expertise. | Change requests must be made to the company selling the software. |
| User-friendliness | Typically less user-friendly; depends on project goals. | Typically more user-friendly with focus on user experience. |
| After-sales support | Community-based support; popular OSS may have commercial support. | Dedicated support teams available, SLA based. |
| Security | Open for review by all; more eyes can help but risks remain. | Vendor is responsible; source code is closed. |
| Vendor lock-in | No lock-in; may face technical dependency. | High switching cost; proprietary lock-in likely. |
| Stability | Varies based on usage and maintainers. | Older products tend to be stable. |
| Popularity | Some are market leaders (e.g., Linux, Apache). | Often preferred in traditional industries. |
| TCO | Lower TCO; depends on maintenance effort. | Higher TCO; varies with user base size. |
| Community participation | Open, collaborative community. | Closed development. |
| Interoperability | Generally higher; depends on maintenance. | Depends on internal development standards. |
| Tax calculation | Difficult; undefined value. | Defined and traceable. |
| Enhancements | Can be user-developed. | Must be requested from vendor. |
| Production suitability | May lack enterprise-level testing. | Usually well-tested for production. |
| Financial sector use | Rarely used without vetting. | Preferred for compliance and support. |
| Warranty | No warranty. | Often includes warranty and indemnity. |

The Most Popular Open Source Software Licenses
Open-source licenses are legal agreements that allow users to run, modify, and distribute software. Most are free, but with conditions like:
- Crediting the original authors.
- Redistributing under the same license terms.
There are over 200 licenses, but popular ones include:
- MIT License: Minimal restrictions; GPL-compatible.
- Apache 2.0: Allows modification and sharing with clear documentation.
- BSD-3-Clause: Similar to MIT; includes protection for original developers.
- GNU GPL: Requires full code release and user rights.
- CDDL-1.0: Allows sharing derivatives but under same terms only when original code is present.
⚠️ It's important to study license terms before using OSS in any project.
