INSIDE THE BOOK

Close the unsafe path.
Keep the street moving.

A traffic signal has software, logins and network connections. The book looks at exposed access, vendor accounts, radio links, and the checks a team needs before and after a security change.

It includes published incidents and clearly labeled illustrative scenarios. The traffic-signal scenarios are not presented as Findavi customer results.
