Introduction

Tune in to learn more about meter tampering, why it is a problem for utility providers and some common ways a meter is tampered.

Detecting case tamper attacks using inductive switches

The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case.  In this section, we will cover how to detect someone trying to open the case of a meter.

Summary

In this section, a summary of the entire Anti-tamper Techniques to Thwart Attacks on Smart Meters training series will be covered.  This summary includes the Detecting Case Tamper Attacks Using Inductive Switches, Detecting Magnetic Tampering Using Hall-effect Sensors and Hardening a Meter Against Magnetic Tamper Attacks sections of the training series.
