Abstract

The embodiment of the invention discloses an APT attack analysis method and system and a server, and the method is used for solving the problem that in the prior art, correlation analysis is difficultto be carried out on a domain name resolution log and an APT attack event. The method comprises the steps of extracting to-be-analyzed log data from a log collection and storage server according to apreset data extraction condition; performing key field matching on each log in the to-be-analyzed log data, and determining a first target domain name generating an APT attack event and a first target IP address resolved by the first target domain name; and according to the first target domain name and the first target IP address, creating an interception list and sending the interception list toa domain name resolution server, so that the domain name resolution server determines whether to respond to a domain name resolution request initiated by a client according to the interception list.According to the technical scheme, correlation analysis between the domain name resolution log and the APT attack event is realized, so that log data for data backup plays a role in discovering APT attacks.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to an APT attack analysis method, system and server. Background technique [0002] In the prior art, the domain name resolution log is generally only used to back up and save the domain name data resolved by the DNS (DomainName System, Domain Name System) server, and there is no corresponding mechanism to compare each log data in the domain name resolution log with APT (AdvancedPersistentThreat, advanced Persistent Threat) events are analyzed. [0003] Therefore, in the process of DNS server processing the user's domain name resolution request, it is impossible to perform APT inspection and judgment on the domain name requested by the user and the IP (Internet Protocol, Internet Protocol) address corresponding to the domain name, and it is impossible to know the domain name accessed by the user, Whether the IP is safe, the threat cannot be discovered when the use...
