What type of credential is recommended to discover Unix machines?

The recommended credential to discover Unix machines is a user with selective sudo access. This type of access is advantageous because it allows the user to execute specific administrative commands needed for discovery without granting full administrative privileges.

Selective sudo access is essential in a security context, as it mitigates risks associated with granting users unnecessary power. This approach aligns with the principle of least privilege, ensuring that users can perform their required functions without exposing the system to potential vulnerabilities that could arise from unrestricted access.

In the context of service mapping, this level of access allows for the necessary discovery tasks, such as querying system information and configuration details, without compromising the overall security posture of the Unix machines.
