Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
To be described in detail to the embodiment of the present invention below convenient for understanding the present embodiment.
Embodiment one:
Fig. 1 is the weak passwurd detection method flow chart based on industrial control system that the embodiment of the present invention one provides.
Referring to Fig.1, it is applied to industrial control system, method includes the following steps:
Step S1, obtains priority query, and priority query includes the port multiple Internet protocol IP and each port pair IP
The weak passwurd scan script answered and weak passwurd library corresponding with each weak passwurd scan script；
Specifically, the weak passwurd scan script different according to different IP port definitions, the port IP and weak passwurd scan foot
It is the relationship of key and value between this, wherein key is keyword, and value is weight, then, the port IP is keyword,
Weak passwurd scan script is weight.Each port IP corresponds to weak passwurd scan script, and each weak passwurd scan script is corresponding
Weak passwurd library is stored in priority query.It, can be according to weight when being scanned to the weak mouth library in priority query
Size order is scanned.
Step S2 is scanned from message queue to the port IP；
Here, include the different ports IP in message queue, the different ports IP can be scanned simultaneously, work as scanning
When to one of port IP, weak passwurd is determined whether there is according to the corresponding relationship in priority query.
Step S3 searches the corresponding weak passwurd scan script in the port IP according to the port IP from priority query；
Step S4 searches the corresponding weak passwurd library of weak passwurd scan script according to weak passwurd scan script；
Step S5 judges in weak passwurd library with the presence or absence of weak passwurd；If it does not exist, then executing step S6；If it does,
Then follow the steps S7；
The port step S6, IP is in a safe condition；
Step S7 obtains the log-on message in the weak passwurd library of modification.
Here, weak passwurd is usually the password being easy by others guesses or the tool of being cracked cracks, such as " 123 ", " abc "
Etc. simple digitals or letter combination.
Specifically, after scanning starts, thread constantly extracts the end IP that port scanner scans from message queue
Mouthful, the corresponding weak passwurd scan script in the port IP is searched from priority query according to corresponding relationship, foot is scanned according to weak passwurd
The corresponding weak passwurd library of this lookup, traverses the combined information that all username and passwords are constituted from weak passwurd library, and judgement is
No there are weak passwurds, if there is no weak passwurd, then illustrate that the port IP is in a safe condition, are not cracked；If there is
Weak passwurd, then corresponding username and password can log in industrial control system, can show the prompt of modification username and password at this time
Information, to modify to username and password.Meanwhile weight of the username and password in priority query is increased,
By constantly scanning, it will priority scan is to common weak passwurd, so as to improve scanning speed.Wherein, port scanner packet
It includes but is not limited to masscan.
Further, message queue obtains in the following manner:
Each port IP is scanned, the port IP being connected to；
The open port IP is obtained from the port IP of connection；
Message queue is constituted according to the open port IP.
Specifically, it when scanning beginning, first has to judge whether the port IP can be connected to, i.e., whether the port IP survives, such as
The survival of the port fruit IP, then illustrate that the port IP can connect communication, that is, is in connected state；Then judge connection the port IP in which
A little ports are to obtain the open port IP in open state, the open port IP is stored in message queue.It is offseting
When the port IP in breath queue is scanned, it is scanned according to the principle of first in first out.
Further, after step S7, this method is further comprising the steps of:
Step S11 obtains the matching times of the log-on message in weak passwurd library；
Step S12 updates weak passwurd scan script according to the corresponding weak passwurd scan script in weak passwurd library and matching times
Corresponding weight.
Specifically, when determining in weak passwurd library there are when weak passwurd, the log-on message in weak passwurd library is modified, wherein step on
Record the combination that information is username and password.When initial, the weight of the corresponding weak passwurd scan script in weak passwurd library is 0, weak mouth
The matching times for enabling log-on message in library are also 0.When being searched whether from weak passwurd library there are when weak passwurd, weak passwurd at this time
As log-on message.If being repeatedly matched to the log-on message, according to the corresponding weak passwurd scan script in weak passwurd library and
With number, the corresponding weight of weak passwurd scan script is updated.For example, when initial, weight 0, when log-on message is matched to once
When, weight becomes 0+1；When log-on message is matched to twice, weight 1+2.
Further, step S2 includes:
The port IP that port scanner scans is extracted from message queue by thread.
The embodiment of the invention provides the weak passwurd detection methods based on industrial control system, are applied to industrial control system, comprising: obtain
Priority query is taken, priority query includes the port multiple Internet protocol IP, weak passwurd corresponding with each port IP scanning foot
Sheet and weak passwurd library corresponding with each weak passwurd scan script；It scans from message queue to the port IP；According to the port IP from
The corresponding weak passwurd scan script in the port IP is searched in priority query；Weak passwurd, which is searched, according to weak passwurd scan script scans foot
This corresponding weak passwurd library；Judge in weak passwurd library with the presence or absence of weak passwurd；If it does not exist, then the port IP is in safe shape
State；If it is present obtaining the log-on message in the weak passwurd library of modification, the weak passwurd suitable for industrial control system can be passed through
Whether scan method detection industrial control system is attacked, and can be scanned simultaneously for various protocols, improve industrial control system
Safety.
