Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The invention provides a network security control method. refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the network security control method of the present invention. In this embodiment, the network security control method includes:

[0040] Step S10 , after successful networking, back up the IP address of the reference DNS resolution server, and judge in real time whether the IP address of the DNS resolution server in the system DNS configuration information has been tampered with.

[0041] Whether the IP address of the DNS resolution server in the real-time judgment system DNS configuration information has been tampered with in this step S10 is specifically: whether the IP address of the DNS resolution server in the system DNS configuration information is consistent with the I...

Abstract

The invention discloses a network security control method comprising the following steps: making a backup of an IP address of a benchmark DNS (domain name system) resolution server after successful networking, and judging whether an IP address of a DNS resolution server in system DNS configuration information is tampered in real time; terminating the execution of network service operations when the IP address is tampered; updating the IP address of the DNS resolution server in the system DNS configuration information to the IP address of the benchmark DNS resolution server; and continuously executing the network service operations. The invention also discloses a network security control device. By adopting the network security control method and device disclosed by the invention, the occurrence of a phenomenon that user information is leaked because the IP address of the DNS resolution server in the system DNS configuration information is tampered can be effectively prevented, and the internet access security of users can be guaranteed.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a network security control method and device. Background technique [0002] When a user uses a smart terminal such as a wireless CPE (Custmer Premise Equipment, which is a wireless terminal access device that receives wifi signals) to access the Internet to perform network business operations, the web page accessed through the domain name is often not the expected page. Because the IP address of the DNS resolution server in the DNS (Domain Name System, Domain Name System) configuration information of smart terminal devices such as the CPE is illegally tampered with by hackers, if the user does not find out and still enters relevant information at this time, the hacker can obtain the relevant information entered by the user. Information, that is, user information is at risk of being leaked, and network business operations have serious security risks. Contents of the inv...
