Abstract: In some implementations, a system includes a set of servers configured to establish a set of virtual machines to provide a computing environment; a set of compute express link (CXL) interface components configured to communicate with the set of servers via a set of CXL interconnects; and a controller configured to at least one of: encrypt protocol data against a CXL interposer security threat associated with the set of CXL interconnects or a malicious extension security threat, provide a secure handshake verification of an identity of the set of CXL interface components, enforce a chain of trust rooted in hardware of the set of CXL interface components; restrict access to an area of memory of the set of CXL interface components that stores security data for verified or secured processes; or perform a security check and set up a set of security features of the set of CXL interface components.
