The code that businesses consume from open source components as well as the code they write themselves must both be secured. Because of this, a lot of organizations are automating open source governance across the entire SDLC with Sonatype, moving security to the development and build phases.
Is open source secure?
No. Undoubtedly, compared to closed source software, open source software has the potential to be more secure. But make no mistake, security is not automatically assured by being open source. Simply put, relying on secrecy to protect software is unrealistic.
The Bell-LaPadula model has two significant drawbacks:
It only offers confidentiality. (no authenticity, integrity, etc.) It assumes that all data are classified and that the classification of the data will never change, but it offers no method for managing classifications.
Which of the following does the Clark-Wilson model not involve?
Items of confidentiality is the right response.
