Is it true to say that the security mechanisms provided by an operating system are less secure than...?

Question

those imposed soley by a web server?

Answer 1

Your OS via updates and and a independent AV supply the protection to your computer. Sites only provided security regards personal information via locks and encryption

Answer 2

That isn't a question with an answer, I am afraid

Operating system security is a must - if the OS allows remote code execution then all bets are off.

Web Servers also need to be secure but that is a separate question. Do you mean "Are web based apps intrinsically more secure that apps that run on the client?" Well, not really. They are just as vulnerable to all the attacks that a local application could suffer and vulnerable to some new ones too.

If you could clarify your question, let me know and I will try to help more.
