A blacklist-based access control method, system, terminal and storage medium

Abstract

The invention provides a blacklist-based access control method, system, terminal and storage medium, all of which include: when a user logs in, recording the user's IP, user name and password; judging whether the IP is currently prohibited from logging in: if not, then Verify whether the username and password match; if the verification does not match, count the total number of first, second and third failures; determine whether the total number of first, second and third failures reach their respective thresholds: if it is determined that the total number of first failures reaches It corresponds to the threshold and determines that at least one of the second and third total failures does not reach the corresponding threshold, then the user name is prohibited from logging in within t1; if it is determined that both the second and third total failures reach their corresponding thresholds, then determine Whether the IP is in the first-level blacklist: If it is determined that the IP is in the first-level blacklist, add the IP to the second-level blacklist; if it is determined that the IP is not in the first-level blacklist, add the IP to the first-level blacklist. The present invention is used to reduce the maintenance cost of the blacklist when performing access control.

Description

technical field [0001] The invention relates to the field of computers, in particular to a blacklist-based access control method, system, terminal and storage medium. Background technique [0002] More and more users are paying attention to access control. The access control strategy can well control the person, IP, time, etc. of the system being accessed, which can improve the security and availability of the system and reduce the risk of system being attacked. [0003] At present, most of the access control strategies used within the company use the blacklist method. However, at present, most blacklist systems need to be updated manually. This method requires high maintenance costs. As a result, when some users use the blacklist system for access control, such as business trips or network replacements, the blacklist needs to be updated. The maintenance cost of the blacklist is relatively high. [0004] Therefore, the present invention provides a blacklist-based access co...
