UDP vs TCP : which is better for privacy and security?

[devidd55 0]

Hello,

 

I have been reading about the differences between UDP and TCP and they basically say that TCP is more reliable, as it does some extra "error-checking stuff", while UDP does no such thing. From that I can inferr basic things for example: TCP guarantees that your downloads are not corrupt in case of connection problems and so on.

 

But as a newbie, i am not sure how to interpret that in another context: Do these extra error checkings also protect your privacy and anonymity against (theoretically) any kind of hacking, like intercepting and compromising the packets, or sniffing them ie spying on your activity online (from the government for example) ? And would i be at a disadvantage when using UDP in that case?

 

Thank you

Hello,

 

please see the quote from the OpenVPN manual, reported here:

If UDP is not throttled in your ISP infrastructure AND your applications do not fall in the very exceptional cases that are mentioned there, you can safely prefer UDP.

 

Kind regards
