This invention discloses one network safety pre-alarming method, which comprises the following steps: a, reading database and taking enough attack affair data; b, processing the polymer analysis on the attack time to get the attack frequency values sequence; c, judging the frequency value sequence circle, if yes, then continuing; if not then executing the sixth step; d, determining circle length; e, computing predict data relative position in the circle and executing eighth step; f, selecting prediction method according to attack frequency value sequence; g, determining prediction type according to the prediction method; h, predicting future time section attack times. The method in this invention can predict future attack situations for both short and long safety trend prediction.

The invention relates to a side channel attack defense method and device based on dynamic memory remapping and cache cleaning. The method comprises the steps of collecting information of virtual machines operating on a virtual machine monitor, wherein the information at least comprises physical pages occupied by each virtual machine and protection memory submitted by the virtual machines; monitoring side channel attacks currently generated based on caches in real time, thereby obtaining attack target information, wherein the attack target information at least comprises attacked target virtual machines, attack frequencies and attacked cache layers; and selecting defense operation, wherein according to the defense operation, cache cleaning operation or memory dynamic remapping operation is selected according to the attacked cache layers in the attack target information. According to the method and the device, the operation efficiency of the virtual machine monitor is taken into consideration; targeted defense is carried out; resource waste is avoided; the security of a cloud computing industry is ensured; the side channel attacks based on the caches can be sensed in real time; and the efficient defense is realized on the basis of not influencing resource sharing to the greatest extent.

The invention discloses a method for detecting a persistent attack of a cloud storage system, and relates to computer storage and information security. The provided method for detecting the persistent attack of the cloud storage system can realize an optimal equipment scanning time interval by adopting an intensive learning method without foreseeing a specific advanced persistent attack model, and can suppress the attack motive of an attacker, reduce the attack frequency and improve the data privacy of cloud storage. The provided method for detecting the persistent attack of the cloud storage system has the advantages that a defense system can design a detection scheme adaptive to a dynamic network and an attack mode according to the attack time interval and duration of an advanced persistent attack in cloud storage equipment and other similar information by intensive learning without knowing the specific advanced persistent attack model. The attack motive of an attacker can be suppressed, the attack frequency can be reduced, and the data privacy of cloud storage can be improved.

The invention discloses a network protection method, device and system. The method comprises that a network access request data packet with basic information needed by present network access is received from a terminal; whether the basic information satisfies a detection condition is determined; and if YES, data in the network access request data packet is confused to obtain a confused data packet, and the confused data packet is sent to a Web server. The method provided by the invention can be used to protect the data packet form the terminal actively, reduce the attacked frequency of the Web server, and ensure the security of user information.

The invention provides a traditional Chinese medicine composition for treating bronchial asthma in the remission stage. The traditional Chinese medicine composition comprises the following raw materials: radix astragali, ephedra, herba epimedii, fructus psoraleae, semen brassicae, gecko, folium eriobotryae, asarum, tangerine peel, ginseng leaf, fructus gleditsiae sinensis, liriope spicata, Chinese yam, fritillaria cirrhosa, cortex acanthopanacis, knoxia root, negundo chastetree leaf, astragalus complanatus, ganoderma lucidum, conyza blinii, magnolia officinalis, semen coicis, aster, glossy privet fruit, dendrobium nobile and pummelo peel. The traditional Chinese medicine composition provided by the invention has the advantages of being capable of obviously improving the clinical symptoms and signs of the asthma in the remission stage, reducing attack frequency, alleviating attack degree, prolonging attack interval and improving the lung function, thus the asthma is effectively controlled, the survival quality of patients is improved, and the advantages of the traditional Chinese medicine for diagnosing and treating the asthma based on syndrome differentiation are embodied; and compared with the western medicines, the traditional Chinese medicine composition has little toxic and side effects and is low in cost.
