Editing Chapter 6: Edge Security and Privacy (section)

==== Privacy Issues in Fog Computing ====
# User privacy
## Fog computing contains large number of IoT devices that are inter-connected via sensors, which generate sensitive data and transmit to fog nodes for processing. This raises the question of guaranteeing user privacy in the case of a breach in a part of the system.
# Data Privacy
## User data can be exposed to network attacker who is trying to steam user's personal data from the transmission medium or relay nodes
# Usage privacy
## User's usage patterns for fog computing usage may get leaked. If the intruder knows when user is accessing the channel, they may target the user's confidential information when the user is not using the channel.
# Location Privacy
## Intruders accessing nodes' location information poses a risk for the user both physically and on the network.
# Network Privacy 
## Since most fog networks are connected over wireless networks, which are relatively insecure, this also poses a ever-present security risk for users. Moreover, maintenance of fog nodes on wireless networks is also challenging since they are present at edge of internet. Both these factors expand the attack surface which makes it more likely for a breach to occur
