Embodiment Construction

[0014] based on the following figure 1 and figure 2 , specifically explain the preferred embodiment of the present invention.

[0015] The invention provides a management method of a kernel firewall. When a service request initiated by a client to a server is rejected by the server's kernel firewall, the client connects to a private connection port of the server, and initiates a firewall modification request to the server through the private connection port. Request the kernel firewall to accept the client request sent by the client. After the server receives the firewall modification request from the legal client, it parses and executes the firewall modification request, and modifies the kernel firewall so that the business request sent by the legitimate client can pass through the server. kernel firewall and get a response from the server.

[0016] The port number of the private connection port is self-defined instead of using a known port number, so as to ensure the priv...

Abstract

A core firewall management method comprises the following steps: when a client side sends a business request to a server and rejected by a core firewall of the server, a valid client side is allowed to connect with a private connection port of the server, and the client side initiates a firewall modification request to the server through the private connection port, and asks the core firewall to accept the client side request sent by the client side; the server receives the firewall modification request from the valid client side, analyzes and executes the firewall modification request so as to modify the core firewall; the business request sent by the valid client side passes the core firewall of the server, and the client side receives a response from the server. The core firewall management method allows the valid client side to obtain connection authority from the server, thus reducing work load of an administrator.

Description

technical field [0001] The invention relates to a management method of a kernel firewall. Background technique [0002] Iptables is a kernel-based firewall that is very powerful and controls the flow of packets by providing the firewall with instructions on what to do with packets from a certain source, to a certain destination, or with a specific protocol type. filter. If a rule in the server's kernel firewall is not set, the client cannot access the system server. For example, if port 21 on the system server is not opened, the client cannot access the system's ftp service. The administrator needs to log in to the system server, and set this rule in the kernel firewall so that the client can have access to the server. This kind of operation increases the workload of the administrator, and it is also a troublesome process for the login and access of some legitimate clients. Contents of the invention [0003] The invention provides a management method of the kernel firew...
