STORAGE DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17944613 titled 'STORAGE DEVICE AND OPERATION METHOD THEREOF
Simplified Explanation
The abstract describes a storage device and a method for operating the storage device. The method involves detecting abnormal operations of a host memory buffer (HMB) located outside the storage device during data processing. When such abnormal operations are detected, the storage device updates a security policy that is applied when writing or reading data from the HMB.
- The storage device detects abnormal operations of a host memory buffer (HMB) during data processing.
- The abnormal operations refer to any unexpected or irregular behavior of the HMB.
- The HMB is positioned outside the storage device, indicating it is a separate memory buffer used by the host system.
- When an abnormal operation is detected, the storage device modifies the security policy applied to data read from or written to the HMB.
- The security policy is a set of rules or measures that govern the access and handling of data in the HMB.
- The purpose of updating the security policy is to enhance the protection of data in the HMB and prevent potential security breaches.
Potential Applications
- Data storage systems and devices
- Cloud computing environments
- Network-attached storage (NAS) systems
- Solid-state drives (SSDs)
- Virtualization platforms
Problems Solved
- Addressing abnormal operations in the host memory buffer (HMB)
- Enhancing security measures for data processing in the HMB
- Preventing potential security breaches and unauthorized access to data
Benefits
- Improved data security and protection
- Real-time detection and response to abnormal operations
- Enhanced control over data access and handling in the HMB
- Mitigation of potential security risks and vulnerabilities
Original Abstract Submitted
A storage device and an operation method of a storage device is provided. An operation method of a storage device includes: detecting an abnormal operation of a host memory buffer (HMB) positioned outside a storage device during data processing; and when the abnormal operation is detected, updating, by the storage device, a security policy applied when writing data to or reading data from the HMB.
