Management Access to Security Contexts
The security appliance provides system administrator access in multiple context mode as well as access
for individual context administrators. The following sections describe logging in as a system
administrator or as a a context administrator:
• System Administrator Access, page 10-8
• Context Administrator Access, page 10-9
System Administrator Access
You can access the security appliance as a system administrator in two ways:
• Access the security appliance console.
From the console, you access the system execution space.
• Access the admin context using Telnet, SSH, or ASDM.
See Configuring Authentication for Network Access, page 23-1 to enable Telnet, SSH, and ASDM
access.
As the system administrator, you can access all contexts.
When you change to a context from admin or the system, your username changes to the default
“enable_15” username. If you configured command authorization in that context, you need to either
configure authorization privileges for the “enable_15” user, or you can log in as a different name for
which you provide sufficient privileges in the command authorization configuration for the context. To
