Abstract

The invention provides a method and device for detecting abnormal login through stack backtracking, and the method comprises the steps: S1, carrying out the backtracking of stack information corresponding to a thread of a login behavior when the login behavior of a user is monitored, and obtaining an API call sequence; s2, comparing the obtained API calling sequence with a pre-collected white list of the API calling sequence; and S3, if the comparison result is inconsistent, detecting an abnormal login behavior. The scheme of the invention has the characteristics of high detection rate, low false alarm rate, real-time performance and the like.

Description

technical field [0001] The invention relates to the field of computer information security, in particular to a method and device for detecting abnormal login through stack backtracking. Background technique [0002] Abnormal login behavior detection is an important part of asset risk management for administrators. Abnormal logins include abnormal logins from unused addresses, logins using illegal authentication information, and attempted blasting. Currently, the methods for detecting abnormal logins on hosts mainly include the following: detection mechanism. [0003] Judgment based on simple rules: Analyze login behavior by recording account login history information, and set login detection frequency rules, so as to establish a whitelist database based on common IP addresses. Login behaviors that are not in the whitelist database are defined as abnormal logins. This detection mechanism has obvious omissions and false positives. [0004] Judgment based on manual rule match...
