I obviously give up and cannot resist NSA or likes surveillance...elwebmaster wrote: ↑You are bringing up a good point but it needs to be taken into context. While open networks make it easy for others to capture your traffic, that doesn't mean that traffic on the cellular network or your "secure" home wifi is safe. Every piece of traffic gets send through numerous routers between you and the receiving site (usually 10-15) controlled by various entities. At each step of the way the traffic may be intercepted or recorded. In fact we know that most traffic (including encrypted traffic) is captured, stored and analyzed for legal compliance and intelligence gathering . You may get some piece of mind by relying on the "green lock" in your browser (HTTPS) and expecting that app developers take you security seriously by adopting such technologies in their apps as well. That's largely a false perception of security. Turns out this technology can also be setup in many broken ways that make it not much more secure than plain unencrypted communication. Add to that services like CloudFlare which allow websites to fool your browser by making it show a green lock while sending the data unencrypted behind the scenes. Or if you want to get really extreme: the organizations responsible for ensuring these "green locks" are given only to legitimate sites and not to others who are trying to steal your data, have made a number of mistakes (willingly or not) over the years and broken that expectation of trust. The idea of using a VPN to "secure" your data is also largely a hoax, because an unknown number of people have access to your unencrypted data on the other end. So unless you are VPNing into your home/work and you are confident the VPN was setup by a qualified professional, you may be taking more risks by using it.
In other words, you shouldn't have any expectation of privacy or security when using a public network whether it is open wifi, or the cellular network, or the public internet (i.e. The Internet).
So, i consider my own home internet/mobile internet providers to be safe enough..
With encryption etc safe enough for my banking etc...
My (and average Joe's) concern more about possible malicious agents on unknown/random wifi networks..
E.g is using my banking apps is safe enough over such networks... is logging to my gmail/outlook/work e-mail safe (presumably they all use TLS or whatever it is called encryption)... stuff like that... probabbly using ssh/sftp over a random wifi is safe, right?
