I want to know without taking physical access, what are the methods that can steal the data in a node.
- When talking about eavesdropping, how can an attacker sniff the packets? Do they need to listen to that node or listen to channel?
- Is there any other way to get nodes data?
- What happens when impersonation attacks happen? Can an attacker get all the data of particular node?
- How can encryption can be used to secure communication? And is there any way to protect keys? If a hacker gets the key does that mean he gets the all?
