Default level of new secuirity zone is

A very specific question!

According to the Cisco documentation, the default level of a new security zone in Cisco ASA (Adaptive Security Appliance) is "untrust".

In Cisco ASA, a security zone is a logical grouping of interfaces that are used to control and monitor network traffic. The default security zone is "untrust", which means that any new interface or subinterface created on the ASA will be automatically assigned to the "untrust" zone.

The "untrust" zone is used to define the external interface of the ASA, which is typically connected to the internet or an untrusted network. The "untrust" zone is used to apply security policies and access controls to traffic entering the ASA from the outside world.

It's worth noting that the default security zone can be changed by the administrator, and multiple security zones can be created and configured on the ASA to meet specific security requirements.
