Problems solved by technology

Increased user operation complexity
[0006] The second is that when the OLT is suppressing, the users connected to the ONU may still continue to attack, which is relatively passive
Can not achieve the effect of directly limiting the attack source
And the normal business of OLT is affected

Embodiment Construction

[0042] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, the present invention discloses an intelligent anti-attack method for a passive optical network system. The method includes three modules: an intelligent anti-attack configuration module, an attack detection module, and an attack source processing module.

[0044] The main function of the intelligent anti-attack configuration module is to configure the action to deal with the source of the attack when the existence of an attack is detected. Actions include limiting the port speed of the attack source, closing the port, taking the ONU offline and setting the time for prohibiting re-online. Intelligent anti-attack divides the degree of attack into two levels: mild and severe, and different actions can be configured for different levels. The different levels of attack defense actions can make the attack defense m...

Abstract

The invention discloses an intelligent anti-attack method for a passive optical network system. The method includes the following steps: 1. When an attack is detected, the action for processing the source of the attack is configured; The level of the behavior; if yes, jump to step 3; otherwise, continue detection; 3. Process the optical network unit of the attack source, and continue detection after completion. The operation of the attack source when an attack occurs and the business recovery when the attack disappears can be completed automatically without manual interference, saving human resources, saving costs, and realizing intelligent operation; it can be applied to EPON OLT equipment and GPON OLT equipment at the same time ; When an attack is detected, the source of the attack is directly processed. Currently, there is no anti-attack, and the general anti-attack is a passive defense, which restricts itself to prevent crashes and affect its normal business.

Description

technical field [0001] The invention relates to a system attack defense method, in particular to an intelligent attack defense method for a passive optical network system. Background technique [0002] Currently, Passive Optical Network (PON) technology has been widely used as a mainstream access technology. Whether it is a broadband passive optical network (GPON, Gigabit-Capable PON) or an Ethernet passive optical network (EPON), it has achieved optical front-end access, which greatly improves the user's bandwidth usage level. Vulnerable to various attacks. If the system crashes due to an attack, the business of a large number of users will be affected. The current GPON standard also has certain requirements for the security of optical line terminal (OLT) equipment. The standard requires that devices should have certain security and attack prevention capabilities. [0003] However, the current implementation generally restricts the message processing of the OLT itself. ...
