Intrusion detection for an information handling system

An information handling system comprising:

• a chassis comprising at least one removable component forming a secure boundary;
• a non-repeating element configured to cycle to a new non-repeating value of a first characteristic when the secure boundary is breached;
• a memory within the chassis;
• and
• a processor within the chassis and coupled to the memory, wherein the processor is configured to perform the steps comprising:
• determining, by the information handling system, a first value for the first characteristic of the non-repeating element;
• retrieving, by the information handling system, a second value for the first characteristic of the non-repeating element, wherein the second value corresponds to a previous time than the first value;
• and
• determining, by the information handling system, an intrusion event occurred by comparing the first value of the first characteristic of the non-repeating element with the second value of the first characteristic of the non-repeating element.

An electro-mechanical switch comprising:

• a housing, wherein the housing comprises an alignment pin, a contact terminal for a general purpose input/output, an opening, wherein the opening is configured to receive a plunger and a spring and wherein the alignment pin extends away from the housing;
• the plunger coupled to the spring, wherein a distal end of the plunger is coupled to a proximal end of the spring and wherein the plunger and the spring define a contact point for a secure boundary, wherein the secure boundary is a cover for an information handling system;
• a non-repeating element, wherein the non-repeating element is enclosed in the housing and coupled to the contact terminal for the general purpose input/output;
• a rotating wiper, wherein the rotating wiper is enclosed in the housing and coupled to the non-repeating element;
• and
• a cover for the electro-mechanical switch, wherein the cover seals a top of the housing.
