Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Intrusion prevention system is as a kind of security protection system that effectively prevents attack, by technology such as traffic characteristic analysis and the detections of depth data bag, intrusion behaviors such as virus, attack, spam are detected and tackle, implement the security strategy of deep layer defence.Intrusion prevention system passes through the network data of a network port reception of equipment from external system; data are detected; after confirming wherein not comprise abnormal movement or suspicious content; by another network port data are sent in the built-in system again; if find that attack is then blocked immediately, therefore can guarantee to enter network by network boundary from the attack data of outside.Intrusion prevention system tends to provide initiatively protection, can tackle activity of invading and aggressive network traffics in advance, avoids it to cause damage, rather than just gives the alarm after malicious traffic stream transmits or arrives simply.The processing data packets engine of intrusion prevention system is specialized custom integrated circuit, can carry out byte-by-byte inspection to the content of the packet of data link layer to the application layer.Intrusion prevention system has a plurality of advantages, as embedded operation, in-depth analysis and control ability, high-quality characteristic storehouse and disposal ability efficiently, the aforementioned capabilities characteristics make intrusion prevention system can realize when carrying out network safety prevention the real-time inspection of network data and effective prevention of attack.
Security strategy is the core of intrusion prevention system, intrusion prevention system is realized effective and in good time protection by disposing rational security strategy, but the security strategy of intrusion prevention system of the prior art is user's manual configuration, the safe class of the security strategy of system is changeless within a certain period of time, there are a lot of drawbacks in the fixing intrusion prevention system of this safe class, user's particular demands can't be satisfied, the ability of equipment and system can not be given full play to.The present invention is directed to the defective that exists in the existing intrusion prevention system, for intrusion prevention system provides a kind of dynamic adjusting method of security strategy, to realize according to the dynamic adjustment of particular case to security strategy in the intrusion prevention system.
Fig. 1 is the flow chart of the dynamic adjusting method embodiment of security strategy of the present invention, and as shown in Figure 1, the dynamic adjusting method of a kind of security strategy provided by the invention specifically comprises the steps:
Because the user uses the frequency difference of network in each period, and use also difference of type of service that network carried out, must make the network state difference of different times, for example central processing unit (CentralProcessing Unit; Hereinafter to be referred as: the types of service that utilization rate CPU), memory usage, link bandwidth and user use etc. are all inequality at each time point.Because the security strategy of intrusion prevention system of the prior art is changeless after user's manual configuration is finished, promptly irrelevant with the situation of change of network state, the situation that security strategy and network state are not complementary will inevitably appear, cause or the safe class of security strategy higher and can not satisfy the situation of network state, perhaps long-term idle situation appears in the low Internet resources that make of safe class.Therefore, the present invention detects and obtains testing result to the network state in each period, adjusts current security strategy according to testing result.Wherein, the information of detection includes but not limited to following several information: network link flow, equipment actual treatment ability and type of service.The network link flow can comprise network link peak flow and network link flow average, promptly the network link flow in a certain period is added up completely, actual conditions with reflection current network link flow, when the network link flow-rate ratio is less or bigger, can adjust security strategy, fully and reasonably to utilize Internet resources.Equipment actual treatment ability can comprise CPU usage and memory usage, overall capacity level to equipment detects, with the current overall operating position of reflection equipment, lower or when higher when equipment actual treatment ability, can realize best equipment service efficiency by adjusting security strategy.Type of service is the type of the presently used main business of user, as mail service, audio frequency and video business or the like, different service types is all inequality to the requirement of the internet security and the network bandwidth etc., judges whether this business is higher to delay requirement, and is perhaps stronger etc. to the requirement of fail safe.For example, when using mail service, this business is had relatively high expectations to fail safe, and promptly the user would rather sacrifice bandwidth requirement and also will guarantee internet security; And when using audio frequency and video professional, this business is higher to delay requirement, and promptly the user wishes that current network bandwidth is enough wide, with the smoothness of the audio frequency and video that guarantee to be play.
After detecting and getting access to current each status detection result, according to this testing result current security strategy is adjusted, promptly, adjust current security strategy according to the type of service of the network link peak flow, network link flow average, CPU usage, memory usage and the current use that get access to.Before the adjustment of carrying out security strategy, need carry out comprehensive analysis and judgement to each information that gets access to, to coordinate current network state, finish reasonable adjustment to security strategy.If the current network link flow is less, equipment actual treatment ability is higher, and the delay requirement of main business then can be adjusted the security strategy of intrusion prevention system when low, to improve the safe class of security strategy, realize protection than high safety grade to network.If the current network link flow is bigger, equipment actual treatment ability is lower, and the delay requirement of main business then can adjust the security strategy of intrusion prevention system when higher, to reduce the safe class of security strategy, improves the treatment effeciency of equipment.In addition, also have other multiple situation, for example the current network link flow is less, and professional delay requirement then needs the overall condition of current state is carried out analysis-by-synthesis when higher, and current security strategy is adjusted and how to be adjusted to decision whether again.
The dynamic adjusting method of a kind of security strategy provided by the invention, according to detected network link flow, equipment actual treatment ability and type of service current security strategy is adjusted, realized the dynamic adjustment of the security strategy of intrusion prevention system has been reached the dynamic equilibrium of treatment effeciency and security protection.
Particularly, above-mentioned steps 101 can be specially: according to default sense cycle, periodically detect any one and combination thereof in network link flow, equipment actual treatment ability and the type of service.During equipment operation, with certain sense cycle current state is detected, this sense cycle is provided with according to the situation of network self for the user, if the variation of network state is more frequent, short sense cycle then is set, otherwise long sense cycle is set.According to the sense cycle that has been provided with, current state is monitored, promptly the type of service of the network link peak flow in the sense cycle, network link flow average, CPU usage, memory usage and use is monitored.According to the monitored results that current state is monitored, obtain each state information in this sense cycle.
Above-mentioned steps 102 can be specially: according to described testing result, on the basis of basic security strategy, adjust the enhancing security strategy in the current security strategy in keeping current security strategy.In embodiments of the present invention, the security strategy in the intrusion prevention system comprises the basic security strategy and strengthens security strategy.Wherein, under any circumstance all dispose the basic security strategy, and can dynamically adjust strengthening security strategy according to testing result, on the basis that is implemented in the basic function of safety protection that guarantees intrusion prevention system, adjust security strategy according to the actual conditions of network.
Further, before step 101, also comprise the steps:
At first, the basic security strategy is set.The user is provided with the basic security strategy of intrusion prevention system according to the situation of network self, the basic security strategy can be for the safe class of system the combination of one or more minimum security strategies.Preserve all security strategies of corresponding device in intrusion prevention system, basic security strategy one or more security strategies for selecting from all security strategies, remaining security strategy are then for strengthening security strategy.In the present embodiment, in order to guarantee the safety of network, under any circumstance, intrusion prevention system all disposes this basic security strategy.
Secondly, according to the protective capacities and the resource occupation information that strengthen security strategy, the safe class that strengthens security strategy is divided.Intrusion prevention system is decided by the security strategy that wherein is provided with the protective capacities of network, the different protective capacities of the corresponding intrusion prevention system of different security strategies, and different security strategy is distinguished by the safe class of security strategy.The user is according to the self networks characteristics, formulate all security strategies in the intrusion prevention system, in the present embodiment, the user is according to the protective capacities and the resource occupation information of security strategy, the safe class that strengthens security strategy is divided, promptly the safe class of the security strategy except the basic security strategy in the intrusion prevention system is divided, that is to say, according to the situation of the protective capacities of each security strategy and resource occupation etc., all are strengthened security strategies carry out the ordering of safe class.In the present embodiment, when dividing the safe class of security strategy, except considering its protective capacities, also consider this security strategy of configuration situations such as resource occupation afterwards, because when carrying out the adjustment of security strategy, the resource that the security strategy that certain protective capacities is very strong may take is bigger, then select the cost performance of this security strategy of increase just not high, therefore need comprehensive its resource occupation information to come the safe class of each security strategy is divided so that in follow-up security strategy adjustment process to the adjustment of security strategy.
When carrying out the initial configuration of the network equipment, utilize said process just can finish to all configurations of the safe class of security strategy in the intrusion prevention system.In addition, when finding the new attack behavior is arranged, intrusion prevention system can be created a new filter, promptly create new security strategy, when new security strategy was created, intrusion prevention system need upgrade current security strategy, to comprise new strategy.Therefore, when the security strategy in the renewal intrusion prevention system, also need new security strategy is carried out the division of safe class, division methods and said method are similar.
