SCP (Secure Copy Protocol) is a protocol that allows users to securely transfer files between servers using SSH (Secure Shell) encryption. SCP encrypts both the data and the authentication information, preventing unauthorized access, interception, or modification of the files1. SCP also preserves the file attributes, such as permissions, timestamps, and ownership2.

A warranty is a type of asset management documentation that is commonly used as a reference when processing the replacement of a faulty server component. A warranty is a guarantee from the manufacturer or vendor that covers the repair or replacement of defective parts within a specified period of time. A purchase order, a license, or a baseline document are not directly related to the replacement of a faulty server component.
