Sniffing

Hi,

I have the following typical setup:

• LoadBalancer/Proxy in front (Nginx)

• Node apps in background

Nginx

• decrypts the SSL requests coming from outside

• forwards decrypted requests to Node apps

• gets back the response

• encrypts the response and sends it to client

I was wondering if in terms of security it is OK to have non-encyrpted connection between Nginx and Node apps.

Especially in terms of packet sniffing.

I found a ~8 year old entry saying that in Linode network it is not possible to sniff (https://blog.linode.com/2008/03/14/priv … k-support/">https://blog.linode.com/2008/03/14/private-back-end-network-support/).

I wanted to have a more recent confirmation of that.

Thanks
