The Security of Code FAQ

Q. How secure Open Source Software? Since anyone can read the code for Open Source Software, doesn't that make Open Source less secure than secret Proprietary Software?


A. It is said by some that because Proprietary software is secret, it is more difficult to find bugs and so to attack these systems.

We believe that because Open Source is subject to more review and testing, Open Source is more secure.

This concept has been best explained by the following quotation:
"If I take a letter, lock it in a safe, hide the safe somewhere in New York, then tell you to read the letter, that's not security. Thats obscurity. On the other hand, if I take a letter and lock it in a safe, and give you the safe along with the design specifications of the safe and a hundred identical safes with their combinations so that you and the worlds best safecrackers can study the locking mechanism - and you still can't open the safe and read the letter - thats security."
