== Scope of GC ESA Program ==
[[File:Esa scope picture.png|525x525px|thumb|Scope of the ESA Program|left]]
As the image on the left shows, the scope of the GC ESA program is high-level, with a focus on enterprise as a whole, but it can also assist with security activities at all layers, in accordance with the [http://www.gcpedia.gc.ca/gcwiki/images/8/81/GC_ESA_Program_Charter.pdf GC ESA Program Charter].
The GC may develop IT security architectures that can be categorized into three groups based on level of detail:
'''High-level view''': Artifacts developed at this layer are high-level with GC Enterprise in scope and have a strategic impact. Examples include an Enterprise Security Concept of Operations or a GC Baseline Threat Assessment.
'''Context-specific view''': Artifacts developed at this layer provide supplementary details, are common, shared or departmental in scope and have a tactical impact. Examples include a specific focus area Security Requirements Traceability Matrix, or a context-specific architecture (e.g. Business Control Profile for a Human Resources System).
'''Solution view''': Artifacts developed at this layer are very detailed, system-specific in scope and have an operational impact. Examples include a detailed design documentation or a Standard Operating Procedure for a Data Loss Prevention System.
