Trigger verification method and device for SSD (Solid State Disk) security freezing lock function and computer equipment

Abstract

The invention relates to a triggering verification method and device for an SSD security freezing lock function, computer equipment and a storage medium. The method comprises the steps that a triggering verification request for the SSD security freezing lock function is obtained; running a test script according to the verification triggering request, and simulating that the BIOS issues a security freezing lock command during startup so as to enable the solid state disk to be tested to enter a freezing state; checking whether the solid state disk is in a frozen state; if it is confirmed that the solid state disk is in the frozen state, simulating and issuing a command of entering a D3cold state to enable the solid state disk to be tested to enter the D3cold state; awakening the solid state disk from a D3cold state, and checking whether the solid state disk to be tested is in a defreezing state or not; if it is confirmed that the solid state disk is in the defreezing state, a Block SID Authorization command is issued in a simulation mode; and checking whether the solid state disk is in the frozen state again. According to the invention, the test efficiency is effectively improved, and the test cost is saved.

Description

technical field [0001] The present invention relates to the technical field of storage systems, and in particular, to a method, device, computer equipment and storage medium for triggering verification of the safety freeze lock function of an SSD. Background technique [0002] The wake-up of the notebook entering "Modern Standby (S0iX)" does not require the assistance of the BIOS system. If the SSD is in the "D3cold" mode after entering the "Modern Standby(S0iX)" state, the SSD will be powered off. According to the "ATA / ATAPI Command Set" protocol, after the SSD is powered on again, the "ATA SECURITY" of the SSD will be changed. FREEZELOCK" status is cleared, which means that users are exposed to a ransomware attack that sets the security password of the "ATA / ATAPICommand Set" protocol to an unknown value. In order to prevent ransomware attacks, it is a difficult problem that the SSD will also trigger the "ATA SECURITY FREEZE LOCK" function after receiving the "Block SID Au...

AI Technical Summary

Problems solved by technology

[0004] The above method has the following disadvantages: 1. It is difficult to select a qualified notebook model, because whether the model supports "Modern Standby (S0iX)" and the SSD is in the "D3cold" state cannot be directly confirmed. Whether the host will issue the "Block SID Authentication" command after waking up is also not directly confirmed
