Salted Hash talks with Stan Engelbrecht about the inherent flaws in security for public transportation systems. Security by design wasn’t something in the forethought when these systems were being developed. A 2015 report from the Department of Homeland Security cited the aging infrastructure as a top risk. There isn’t much that can be done to address all of the risks and problems (potential and existing) short of replacing much of the transit infrastructure. In the meantime, there has been a lot of focus on improving incident response and improving segmentation where possible.”]
