The main concern is that because free and open source software (Foss) is built by communities of developers with the source code publically available, access is also open to hackers and malicious users. As a result, there could be the assumption that Foss is less secure than proprietary applications..
Then, is open source software secure?
Proprietary software is inherently more secure than open source software. But a commercial licence doesn't guarantee security. Unlike proprietary software, open source projects are transparent about potential vulnerabilities. With paid software you simply have to trust the vendor.
Subsequently, question is, is closed source software more secure? In this regard, open source software is more secure than closed source software. Besides, open source software allows users to evaluate how secure the software is by themselves because they have the access to its source code. That is not possible for closed source software.
Furthermore, can you trust open source?
If you don't trust the generally provided built applications, you can download the source code yourself, verify and compile it to your own build. No, open-source software is not, inherently, any more secure than closed-source software. But it's not, inherently, any less secure, either.
Is open source software easier to hack?
Open-source advocates suggests that it is way more secure than closed source, hence more difficult to hack. The other team suggests that because it is open-source, and because it is available to anybody, including hackers to inspect, it is much more easier to find and exploit security bugs.
