The invention discloses a method for realizing that a network terminal can safely access a public network. The method comprises the following steps: a network access controller is connected in series between the network terminal and the public network; when a firewall strategy database is required to be configured, a user on a network terminal submits configuration request information; the network access control server generates a group of corresponding configuration command data packet which is transmitted to the network terminal according to the configuration request information; the group of configuration command data packet is captured by the network access control server which is connected in series on the link so as to analyze and execute the corresponding configuration command and complete the update to the configuration of firewall policy; and the user on the network terminal access the public network under the security protection of the firewall policy configured by the network access control server. The invention also discloses a system for realizing that the network terminal can safely access the public network and the network access control server. The method, the system and the network access control server not only can ensure that the network terminal can safely access the public network, but also can be convenient for a user to use.

The embodiment of the invention provides a hard-disk safety-access control method and a hard disk. According to the hard-disk safety-access control method, the hard disk comprises an IP (Internet Protocol) interface and a control panel, and the hard-disk safety-access control method comprises the following steps of receiving an access data packet of a user by the IP interface, and sending the access data packet to the control panel; unpacking the access data packet by the control panel to resolve an authentication data packet, wherein the authentication data packet comprises the access authority information of the user; detecting the access authority information of the user according to a stored safety strategy, and determining whether the access of the user is legal or not, wherein the corresponding relation of the access authority information of the user and the sector mark of each sector in the hard disk is recorded in the safety strategy; if the access of the user is legal, then carrying out safety verification on the access data packet of the user by using a safety algorithm; if the access data packet of the user passes the safety verification, then allowing the user to access the data in the corresponding sector in the hard disk according to the sector mark. The access safety for the hard disk is improved by the embodiment of the invention.

The invention aims at providing a power grid object access control device capable of realizing safety configuration and access of power grid model data. The device is characterized by including a layered division and security permission configuration module of the power grid model data and an access security control module; the layered division and security permission configuration module realizes layered division and security permission configuration of the power grid model data; and the access security control module realizes access security control of a power grid model. Through hierarchical organization of the power grid model according to region, sub regions, power stations and voltage levels, classification of other power grid objects such as devices, terminals and measurement devices and the like into corresponding hierarchies according to incidence relations, and combination of access permissions of system access users for the data and the hierarchical result, the device realizes access security control which is appropriate in granularity and enables security access of operation data of the whole power grid to be corresponding to a management system which is currently in effect.

The invention discloses a network terminal audio internal and external network intercommunication system and method. The network terminal audio internal and external network intercommunication systemcomprises an internal and external security gateway, wherein the internal and external network security gateway is composed of an internal and external network separated signaling gateway SGW and an internal and external network separated media gateway MGW; the SGW is divided into an external network signaling gateway SGW-A and an internal network signaling gateway SGW-B; the MGWs are respectivelydeployed in an external network and an internal network; the SGW-A and the SGW-B cooperate to realize SIP signaling interaction; the MGWs are divided into an external network media gateway MGW-A andan MGW-B internal network media gateway which are respectively deployed in the external network and the internal network; and the MGW-A and the MGW-B realize real-time media stream intercommunicationthrough an E1 board card. According to the network terminal audio internal and external network intercommunication system, the external security gateway and the internal security gateway are deployedin the information intranet and the information extranet, and the innovative application of the information security isolation device is matched, so that the security access of the existing network signaling stream and media stream of the mobile internet terminal society is realized.

The invention discloses a micro-isolation protection system and method adopting a zero-trust architecture, the system comprises a logic architecture and a physical architecture, the logic architecture comprises an execution layer, an collection layer, a persistence layer, a logic function layer and a display layer; the physical architecture comprises a strategy control center, a safety gateway and an Agent plug-in; according to the invention, based on full understanding of the cloud computing environment, under the idea of zero-trust safety, multiple safety technologies such as network micro-isolation, safety gateways and system environment perception are integrated, and the effects of south-north traffic safety admission, east-west traffic (adaptive management and control, and real-time network strategy association of the safety state of access equipment) are finally realized.
