Abstract

The invention discloses a security detection method and device for data files, relates to the technical field of network security, and is used for solving the problem that the existing data file security detection precision is relatively low. The main technical scheme of the invention is as follows: downloading requests of the data files are received; whether downloaded contents of the data files are data contents in a pre-set white list or not can be judged; data contents corresponding to multiple legal data files are stored in the pre-set white list; and, if not, alarm information is output. The security detection method and device disclosed by the invention are mainly used for detecting whether the downloaded data files are safe or not.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for security detection of data files. Background technique [0002] With the rapid development of network communication technology, network attack and defense will never end. The development of technology has made the form of network attacks constantly changing, and many new attack methods have been derived, and watering hole attacks are one of them. The so-called "watering hole attack" means that the hacker finds the weakness of the website frequently visited by the victim by analyzing the network activity pattern of the victim, first captures the website and implants the attack code, and waits for the victim to visit to carry out the attack. The attacker of the watering hole attack achieves his attack purpose by tampering with the data in the attacked website, such as modifying the data download address in the attacked website to a download address...
