Abstract

The embodiment of the invention discloses a GOT table measurement method. The method comprises the steps of during the process of running a process, obtaining the initial address and length of a GOT table to determine the complete GOT table needing to be measured according to the initial address and length of the GOT table, wherein the GOT table specifically comprises the GOT table of the processand the GOT table of a dynamic library on which the process depends; furthermore, carrying out the integrity measurement on each element in the determined GOT table, or carrying out the integrity measurement on the whole GOT table, so that the integrity measurement of the GOT table is realized, and the integrity measurement of the GOT table is added during the process of dynamically measuring thesoftware integrity.

Description

technical field [0001] The present application relates to the technical field of advanced persistent threat defense, in particular to a global offset table measurement method, a dynamic measurement method, and related devices and equipment. Background technique [0002] Advanced persistent threat (APT), also known as targeted threat attack, refers to the continuous and effective attack activities carried out by an organization against a specific target. At present, APT attacks are becoming more and more popular. Attackers can achieve the purpose of eavesdropping on privacy and illegally obtaining benefits by implanting malware or tampering with system software, which poses a great challenge to network security. [0003] At present, many institutions and enterprises mainly use software integrity protection technology to defend against APT attacks. Software integrity technology can protect the various stages of the entire software life cycle to achieve the purpose of defending...
