Network device telnet weak password detection method and device

Abstract

The invention provides a network device telnet weak password detection method and device. A plurality of weak password dictionaries are preset, and each weak password dictionary is configured according to different types of network devices. The method comprises the steps: performing the password matching testing of each network device with a telnet port, wherein each password matching testing operation comprises the steps: selecting a weak password dictionary corresponding to the type of the network device, and adopting the weak password login information of the selected weak password dictionary for login matching. If the login is successful, the network device has a weak password, and the weak password login information includes a weak password, or a username and a weak password. The detection method greatly improves the efficiency of detecting weak passwords of the intranet devices of an enterprise, and reduces the risk that an attacker remotely logs into the intranet of the enterprise to implement the attack.

Description

technical field [0001] The invention relates to computer and network technologies, in particular to a method and device for detecting weak telnet passwords of network equipment. Background technique [0002] With the continuous development of computer and network technology, the enterprise intranet has also been popularized, and various electronic devices in the enterprise have gradually become network-connected devices, and telnet is the standard protocol and main method of Internet remote login service. Network devices have the ability to work with remote hosts. [0003] At present, in enterprises, especially large enterprises, there are a large number of network devices that can provide telnet services, and if these devices have weak passwords for telnet login, there will be great security risks. However, it is very time-consuming and inefficient to detect whether there are weak passwords in the telnet login of the internal network devices of the enterprise one by one. ...
