Secure Boot Could Eliminate Botnets - But Manufacturers Ignore It

Author: Brian Karas, Published on Dec 29, 2016

Increased cyber attacks have motivated video surveillance manufacturers to begin to release hardening guides, instructing users on how to better secure devices from attack. These guidelines put the onus on the installer or user to secure devices connected to the internet, but manufacturers could take another approach that would secure devices from software exploits, even if an attacker had the admin password.

"Secure Boot" support would all but eliminate exploits like Mirai, and by extension would make it less profitable for attackers to target security devices. Secure Boot is even available in some chipsets already in cameras, so why do manufacturers not enable it? In this report we provide an overview of Secure Boot pros and cons.
