Network security protection method and device

Abstract

The invention discloses a network security protection method and device. the method comprises recording a web access log through a server, wherein the web access log comprises accessed network addresses of the server each time; obtaining the log content in the access log within preset period; calculating the access number corresponding to network addresses identical in at least part of fields in the log content and determining the network addresses with the access number larger than the reference number are incredible network addresses, wherein the reference number is the Nth value after sequencing the access number corresponding to the network addresses identical in at least part of identical fields, and N is a preset value; sealing the determined incredible network addresses. By means of the method and the device, the accessed network addresses which do not meet the specification are sealed automatically, and the stability and the safety of websites are guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a network security protection method and device. Background technique [0002] Computer network is the most important information facility in today's society. The development of network communication has greatly promoted the development of the whole society. Various industries use network for information communication to varying degrees. However, the current network communication based on the network address IP did not fully consider security factors at the beginning of the design, so network devices are often attacked from the network, and these attacks have caused great harm. Because the security factor was not fully considered at the beginning of the design of the IP network protocol, the network IP data packet itself has no credible identification, and it is easy to forge or tamper with the IP data packet to evade the network security defense device and achi...

However, the current network communication based on the network address IP did not fully consider security factors at the beginning of the design, so network devices are often attacked from the network, and these attacks have caused great harm

Because the security factor was not fully considered at the beginning of the design of the IP network protocol, the network IP data packet itself has no credible identification, and it is easy to escape the network security defense device by forging or tampering with the IP data packet, and then achieve the purpose of attack.
