Explanation
Data loss prevention (DLP) solutions can prevent the accidental or intentional loss of sensitive data. DLP tools can identify and protect sensitive data by classifying and categorizing it, encrypting it, or blocking it from being transferred outside the organization's network.

Explanation
SOC2 is a type of audit report that provides assurance on the security, availability, processing integrity, confidentiality, and privacy of a service organization's systems. It is based on the Trust Services Criteria developed by the American Institute of Certified Public Accountants (AICPA). A SOC2 report can provide proof that customer data is being appropriately protected by the hosted data provider1

Explanation
SSH stands for Secure Shell, which is a protocol that can be used to securely transfer files over the internet.
SSH uses encryption and authentication to protect the data in transit and ensure the identity of the sender and receiver. SSH can also support compression, tunneling, and port forwarding. SSH can be used to send files to a business partner by using a command-line tool such as scp or sftp, or by using a graphical user interface (GUI) tool such as FileZilla or WinSCP. SSH can also be used to remotely access and manage servers or devices over the internet. References:

Explanation
If the systems are running unsecure protocols and the company that developed them is no longer in business, it is likely that there are no patches available to remediate the issue. References:

Explanation
Federation is an access management concept that allows users to authenticate once and access multiple applications or services that trust the same identity provider. Open authentication is a standard protocol that enables federation by allowing users to use their existing credentials from one service to access another service. The company is most likely using federation and open authentication to safeguard intranet accounts and grant access to multiple sites based on a user's intranet account. For example, the company could use an identity provider such as Azure AD or Keycloak to manage the user identities and credentials for the intranet account, and then use open authentication to allow the users to access other company-owned websites without having to log in again.
