- Security Testing:Both open source and proprietary software development employ various security testing techniques, such as penetration testing and fuzzing. However, the resources allocated for security testing can differ. Open source projects may have limited resources compared to proprietary software, requiring creative approaches to ensure adequate security testing coverage.
- Vulnerability Management:Open source projects typically have a more transparent vulnerability management process, with public disclosure of vulnerabilities and coordinated patch releases. This transparency fosters trust and enables users to proactively mitigate risks. Proprietary software development may have a more controlled vulnerability management process, with less public disclosure and a focus on protecting intellectual property.
