Device and method for detecting object reuse performance of host computer based on hard disk

Abstract

The invention relates to a detection device based on host anti-object reusability of a hard disk and a detection method thereof. The detection device is mounted on a host to be detected, is provided with an address acquisition module, an overwriting frequency monitoring module and an information display module, and detects the delete strength of a data delete tool on another host to be detected, so as to judge the anti-object reusability of the host to be detected by combining the evaluative criteria of the anti-object reusability and according to the detecting result. The detection method is as follows: firstly checking whether the host to be detected is mounted with the data delete tool; if the host to be detected is not mounted with the data delete tool, confirming that the host computer has object reusability, i.e. the anti-object reusability is 0; and if the host to be detected is mounted with the data delete tool, utilizing the detection device of the invention to detect the delete strength of the data delete tool, and judging the anti-object reusability of the host to be detected according to the evaluative criteria of the host computer to be detected and the detecting result. The detection device of the invention has simple structure, easy realization, safe, simple, convenient and fast operating steps and strong enforceability.

Description

technical field [0001] The present invention relates to a detection device and a detection method based on a hard disk-based host object reuse performance, specifically, a device and method for detecting the deletion strength of a data deletion tool installed in a host; Technical field of information security and computer operating system. Background technique [0002] In the field of computer technology, the object is the carrier of information, and the information carriers involved in the field of computer technology include shared memory, mapped memory (ie virtual memory), semaphores and variables, message queues, and disk files. A subject is a person, process, or device that causes information to flow between objects. [0003] The trusted computing base of a computer information system is a general term for various protection devices in a computer system, including hardware, firmware, software, and a combination responsible for implementing security policies. It establ...

Problems solved by technology

[0021] When a data deletion tool deletes data, it is impossible for ordinary users to know how many random number overwriting and writing operations are performed, that is, whether the deletion intensity is sufficient; it is also impossible to judge whether the currently used data deletion tool can achieve Whether the maximum data security and complete deletion can effectively prevent object reuse and information leakage
