prevent packet sniffing

well im looking for a way , ANY way, to prevent or help prevent, my machine from being sniffed with a packet sniffer on a network, i dont know if this exists, but whatever there is , a firewall or something, and ill take a look at it

thanks

 

Hello Hitman3266,
Unfortunatly a firewall cannot protect data that as left your PC. A sniffer can easily intercept comms within a network. The only way is to encrypt data sent/ received. This can still be intercepted on a network, but will not be understood if encryption is good.

 

so sites using https, they cant be sniffed cause its encrypted correct? or they can be sniffed but the data will be useless, yes?

 

Hi Hitman3266,
The sniffer can still intercept, but yes, the data is encrypted.

You should take look at the "Privacy Related Topics". This should give you info on what you are looking for. A good starting point would be this thread
