What is a common characteristic of a Local User authentication method?

A common characteristic of a Local User authentication method is that it stores user credentials directly within the firewall itself. This method allows administrators to manage user accounts, passwords, and access permissions locally, without relying on external servers or databases.

Local User authentication is particularly beneficial in scenarios where simplicity and speed are necessary. Since everything is managed within the firewall, administrators can quickly add or modify user accounts. This method is straightforward and often used in smaller environments or where specific compliance and control over user access are needed without the complexities of integrating with external identity providers.

In contrast, other methods like requiring external servers for authentication involve more complex infrastructures, which could introduce latency or dependency on external systems. Options like remote access and dynamic IP addresses refer to different aspects of network connectivity and user access but do not directly relate to the core characteristic of Local User authentication.
