Abstract

The embodiment of the present invention discloses a method and system for increasing the complexity of user passwords under the operating system. The method includes creating a user password dictionary file for the operating system, adding the dictionary file to the configuration file of the password management system, and adding the password The basis of library execution inspection is switched to the dictionary file; check whether the dictionary file is switched successfully, and restrict the password operation behavior of the root user after the switch is successful, and when modifying and setting passwords, the passwords of all users are checked in the dictionary. The present invention creates a user password dictionary file and uses the dictionary file as a basis for checking passwords to limit the password operation authority of the root user. Passwords will be forced to check the dictionary, and all password words added to the dictionary by the password administrator will be restricted from use, improving the security performance of the operating system.

Description

technical field [0001] The invention relates to the technical field of operating system security, in particular to a method and system for increasing the complexity of user passwords under an operating system. Background technique [0002] At present, manufacturers in the field of key application mainframes each have their own operating systems running on minicomputers. These key application hosts are widely used, including banking, telecommunications, transportation, energy and other fields. Key application hosts often play a key role in application scenarios. In addition to eliminating the possibility of device failure, it is very important to strengthen the security of the host and prevent hacking. [0003] Improving the complexity requirements of host operating system user passwords to avoid being violently stolen or cracked by criminals is one of the important links in host system security reinforcement. If the external network layer and firewall are breached, and the...
