Explanation:
System Execution Space
Unlike other contexts, the system execution space does not have any Layer 2 or Layer 3
interfaces or any network settings. Rather, it is mainly used to define the attributes of other
security context attributes. Here are the three important attributes configured for each context in
the system execution space:
Context name.
Location of context’s startup configuration.
The configuration of each context is also known as a configlet. Interface allocation.
Additionally, many optional features, such as interface and boot parameters, can be configured
within the system execution space. The important features that can be set up through the system
execution space

The system execution space configuration resides in the nonvolatile random-access memory
(NVRAM) area of the security appliance, while the configurations for security contexts are stored
either in local Flash memory or on a network storage server using one of the following protocols:
TFTP
FTP
HTTPS
HTTP
The system execution space designates one of the security contexts as the admin context, which
is responsible for providing network access when the system needs to contact resources.
