Blacklist-based access control method and system, terminal and storage medium

Abstract

The invention provides a blacklist-based access control method and system, a terminal and a storage medium, and the method comprises the steps: recording an IP, a user name and a password of a user when the user logs in; judging whether the IP is forbidden to log in or not at present; if not, verifying whether a user name and a password are matched or not; if not, counting the total number of first, second and third failures; judging whether the first total failure number, the second total failure number and the third total failure number reach respective corresponding threshold values or not;if judging that the first total failure number reaches the corresponding threshold value and judging that at least one of the second total failure number and the third total failure number does not reach the corresponding threshold value, prohibiting the user name from logging in within t1; if it is judged that the second failure total number and the third failure total number both reach the respective corresponding threshold values, judging whether the IP is in a first-level blacklist or not; if it is judged that the IP is in the first-level blacklist, adding the IP into a second-level blacklist; if it is judged that the IP is not in the first-level blacklist, adding the IP into the first-level blacklist. The method and the device are used for reducing the maintenance cost of the blacklist during 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...
