Secure event log management
A trusted device includes a secure interface and a host interface, the secure interface being isolated from the host interface by an isolated environment. A write file of the host interface receives an entry from an untrusted host device connected to the trusted device. A processor of the isolated e...

| description | A trusted device includes a secure interface and a host interface, the secure interface being isolated from the host interface by an isolated environment. A write file of the host interface receives an entry from an untrusted host device connected to the trusted device. A processor of the isolated environment retrieves the entry and determines log data associated with the entry, such as the date and time of the entry. Using the log data, the processor records an event log entry in a secure storage of the isolated environment. Once recorded, the entry cannot be deleted or altered. An authorized user, however, can then access the event log entry from the secure storage, such as by providing a request for the event log entry via the secure interface of the trusted device and/or the host interface of the trusted device. |
