Embodiment Construction
[0042] The embodiment of the present invention provides a collaborative defense patch protection method, which uses a code review mechanism to find program loopholes and generate patch programs, ensuring the security of instant patches after replacement. Use the method of program dynamic injection to solve the problem of patch installation without recompilation. At the same time, the cooperative algorithm is used to protect the hosts in the same network, which can realize the coordinated defense of the network system.
[0043] The specific implementation manners of a collaborative defense patch protection method, device, and storage device provided in the embodiments of the present invention will be described below with reference to the drawings in the description.

The invention provides a collaborative defense patch protection method, a collaborative defense patch protection device and storage equipment, which are used for solving the problems that the existingpatch technology is narrow in application range and cannot realize network collaborative defense, and comprise the following steps of: searching a program bug through a code auditing method and extracting a bug feature vector; proposing a modification code based on the program bug, and generating a patch module program; a preloading technology is used for improving the loading priority of the patch module program; monitoring a kernel and an application process in a program running process, extracting a to-be-detected feature vector, and comparing the to-be-detected feature vector with the vulnerability feature vector to judge whether the to-be-detected feature vector is a dangerous process or not; extracting configuration files of the hosts judged to be dangerous processes to form configuration feature vectors, scanning other hosts in the network, determining other hosts containing the same dangerous process in the network, performing patch module program background sharing, and dynamically loading patch module programs.
Description
technical field [0001] The present invention relates to the technical field of network security, in particular to a collaborative defense patch protection method, device and storage device. Background technique [0002] Computers usually use program patches during security protection. At present, technologies such as virtual patches are generally used for protection, and the methods adopted are mainly rule set processing and protection item scanning. The general patch processing method can only target specific types of vulnerabilities. Some patches can only be intercepted against vulnerability attacks. Official patches need to be restarted and installed according to the specified steps, which has certain operational complexity. It can defend against specific hosts that have been patched, but cannot achieve network coordinated defense. Contents of the invention [0003] Embodiments of the present invention provide a cooperative defense patch protection method, device and ...
