wherein the security weakness comprises at least a set of categories that includes;

dividers among the different ones of the plurality of different portions of the secured area having the different levels of the security having both a physical material strength and an impact strength below a predetermined threshold, walkways or corridors that lead only from a first one of the plurality of different portions of the secured area having a first one of the different levels of the security to a second one of the plurality of different portions of the secured area having a second one of the different levels of the security, and a mismatch between total authorized users of the secured area and a number of authorized users within a selected one of the plurality of different portions of the secured area with a higher relative one of the different levels of the security.

2. The apparatus as in claim 1 wherein the processor compares an impact resistance of a window separating two portions of the plurality of different portions of the secured area with a threshold minimum impact level.

3. The apparatus as in claim 1 wherein the processor identifies an absence of or easily removable dividers separating two portions of the plurality of different portions of the secured area having the different levels of security.

4. The apparatus as in claim 1 wherein the processor detects that the number of the authorized users within the selected one of the plurality of different portions of the secured area with the higher relative one of the different levels of the security is equal to or greater than a number of the authorized users in adjoining ones of the plurality of different portions of the secured area.

5. The apparatus as in claim 1 wherein the processor detects that the number of the authorized users with the selected one of the plurality of different portions of the secured area with the higher relative one of the different levels of the security is equal to or greater than a predetermined threshold or percentage of a number of the authorized users in adjoining ones of the plurality of different portions of the secured area.

6. The apparatus as in claim 1 wherein the processor detects the authorized users that are members of both a first group of the authorized users that are only allowed into an identified one of the plurality of different portions of the secured area and a second group of the authorized users that are excluded from the identified one of the plurality of different portions of the secured area.

7. The apparatus as in claim 1 wherein the processor determines an access criterion for each of the plurality of different portions of the secured area.

8. The apparatus as in claim 7 wherein the access criterion for a lowest relative one of the different levels of the security comprises presentation of a valid access card.

9. The apparatus as in claim 8 wherein the access criterion for a higher one of the different levels of the security above the lowest relative one of the different levels of the security comprises an access card and one or more of a personal identification number and a biometric parameter read by a biometric reader.

10. An apparatus comprising:

a security system having a secured area with a number of different portions, wherein each one of the number of different portions includes a respective security level;

a building information model (BIM) of the secured area embodied in a memory of the security system;

an analysis engine of the security system that identifies different ones of the number of different portions of the secured area having different ones of the respective security level by referencing the BIM and a respective partition between the different ones of the number of different portions of the secured area having the different ones of the respective security levels; and

a processor of the analysis engine that analyzes a context of the respective partition between each of the different ones of the number of different portions of the secured area having the different ones of the respective security levels and compares the context with a respective rule of a plurality of rules related to the context,

wherein the processor alerts a user about a security weakness based upon an interaction between the different ones of the respective security levels of the different ones of the number of different portions of the secured area defined by the BIM and physical characteristics of the different ones of the number of different portions of the secured area defined by the BIM, and

wherein the security weakness comprises at least a set of categories that includes;

dividers among the different ones of the number of different portions of the secured area having the different ones of the respective security levels having both a physical material strength and an impact strength below a predetermined threshold, walkways or corridors that lead only from a first one of the number of different portions of the secured area with a first one of the respective security levels to a second one of the number of different portions of the secured area having a second one of the respective security levels, and a mismatch between total authorized users of the secured area and a number of the authorized users within a selected one of the number of different portions of the secured area with a higher relative one of the respective security levels.

11. The apparatus as in claim 10 wherein the processor displays a map showing a location of the security weakness.

12. The apparatus as in claim 10 wherein the processor prompts the user with a correction for the security weakness.
