How difficult is it for an attacker to intercept traffic between multiple VDSs?

Question

Information Security

Is it safe to load scripts from the background server via http to all client servers?

Answer 1

If you exclude the possibility that an attacker has access to the equipment:

• ISP VDS
  
• Backbone Internet providers through which traffic travels
  
• SORM systems and the like
  

then sleep well. Otherwise, generate self-signed certificates or get free ones from Let`s Encrypt and use HTTPS. Work for 10 minutes.

Answer 2

HTTP is not protected in any way, therefore, naturally, it is not safe in any way. But if, as correctly noted in the answer above, you use a certificate and HTTPS, then everything will be (in general) in order.
It’s also important to understand who the system administrator is and where the server is hosted - if in Europe, everything should be ok, after all, the GDPR is active. For the sake of interest, you can also set up a VPN to send scripts :)))))
