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 present invention discloses an intelligent anti-attack method for a passive optical network system. The method comprising the following steps: 1, detected the presence of attacks, attack source processing configuration when the action; 2, timed to detect whether the attack occurred, as well as attacks in which the level of behavior; If you jump to Step 3, if otherwise continue probing; 3, the source of the attack on the optical network unit for processing, after the completion of continued exploration. The present invention, when the attack occurred on the source of the attack and the attacker disappeared recovery operation when the business, automatic completion, without human interference, save manpower resources, cost savings, intelligent operation; can be applied to both EPONOLT equipment and GPONOLT equipment; detection when an attack occurs, deal directly attack the source, there is no defense to attack, attack prevention are generally passive defense, to restrict itself to prevent collapse, affecting their 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. ...
