Editing Chapter 6: Edge Security and Privacy (section)

==='''Secure Firmware Updates and Lifecycle Management'''===

Edge devices are often deployed in inaccessible locations for long periods, making remote patching essential—but risky.

'''Security Concern''': Malicious actors could intercept or spoof over-the-air updates, leading to bricked devices or persistent backdoors.

'''Insufficient Tools''': Many embedded devices lack secure boot or digital signature verification mechanisms to confirm update authenticity.

'''Case Study''': The infamous Mirai Botnet exploited thousands of edge devices, including DVRs and routers, with outdated firmware and hard-coded credentials, highlighting the urgent need for secure firmware lifecycle practices.
