I support free and open source software (FOSS) like VLC, Qbittorrent, Libre Office, Gimp…
But why do people say that it’s as secure or more secure than closed source software? From what I understand, closed source software don’t disclose their code.
If you want to see the source code of Photoshop, you actually need to work for Adobe. Otherwise, you need to be some kind of freaking retro-engineering expert.
But open source has their code available to the entire world on Github or Gitlab.
Isn’t that actually also helping hackers?
Its relatively easy. First of all if someone would implement a backdoor its much easier to find out, since you can look at the code directly. Second is, that a lot of people actually do this. Looking at the code of projects and searching for ways to find security holes in it.
So even if it isn’t that much more secure than closed source, its much easier to trust simply because people can search for vulnerabilities much easier.
One great example of why open source code is easier to realise backdoors would be the xz Security breach.
