Embodiment Construction

[0075] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0076] As mentioned in the background art, at present, methods such as code review, black box testing, and document research are usually used to detect system unknown vulnerabilities. Specifically, vulnerability detection technologies such as source code scanning, disassembly scanning, and environmental error injection are used for detection. However, the detection of unknown vulnerabilities through the above method has a relativel...

Abstract

The invention discloses a vulnerability detection method and device, relates to the technical field of security, and mainly aims to reduce the search range of an unknown vulnerability detection hole,simplify the vulnerability detection process and save the time consumed by detection, thereby improving the vulnerability detection efficiency. The method comprises the following steps: carrying out virtualization processing on a system of terminal device; Using a virtualized virtual machine monitor to perform memory permission monitoring on an operation behavior corresponding to the terminal device so as to detect whether the operation behavior has a memory access violation or not; And if the memory access violation occurs, determining that a suspected unknown vulnerability is detected, and storing a context environment corresponding to the operation behavior, the context environment being used for further detecting the suspected unknown vulnerability. The method is suitable for vulnerability detection.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a method and device for detecting vulnerabilities. Background technique [0002] With the rapid development of the Internet, the diversified development of computer applications, such as e-mail, online banking, instant messaging and other applications are widely used in all aspects of user life and work, network data security leaks emerge in endlessly, terminal data security protection is urgent . Generally, vulnerability detection can be divided into detection of known vulnerabilities and detection of unknown vulnerabilities. The detection of known vulnerabilities mainly uses security scanning technology to detect whether there are published security vulnerabilities in the system; the purpose of unknown vulnerability detection is to discover possible but undiscovered vulnerabilities in the software system. [0003] At present, code review, black box testing, document researc...
