Original Abstract Submitted
Instead of incorporating a single interface towards the host for transferring data, utilizing a designated write-only storage logging device. The write-only storage logging device can accept sequential streams and automatically overwrite. The controller will read the log material in a secure manner using a different and separate physical connection than the one used for write. The storage device may have LBA ranges that work as write-only as well as other LBA ranges, which are normal (both reads and writes are enabled). Both options will allow for a traditional file system as well as sharing the storage, but will still protect the log areas that would be used for events that should not be read out.
