password in any position above, then, I believe that the security of the password will greatly improve a few levels. Moreover, do similar registration page or other such pages, the use of regular to verify, can effectively control, users fill in the password not too simple, such as can not be pure numbers, can not have special symbols, etc., or require a mix of numbers and English text composition.The above is only a few small methods, of course, if

1. SQL injection file write (user authentication required)Workaround: Through the establishment of a filter method, all user input information to clean up filtering. Filtering the dangerous characters contained by user input can prevent malicious users from causing the application to perform unplanned tasks, such as starting arbitrary SQL queries, embedding JavaScript code that will be executed on the client, running various operating system commands, and so on.It is recommended to filter out al

SPRINGMVC's controller is singleton (non-thread safe), which is probably the difference between him and struts2.Original Address: thread security issues with spring concurrent access Like struts, Spring's controller defaults to Singleton, which means that every request comes in and the system is processed with the original instance, which results in two outcomes: one is that we don't have to create a contr

pointer (address), at which point the *p will cause unpredictable conditions. 3.Handling Uninitialized pointersThere are three ways to handle uninitialized pointers:A, Initialize pointers with NULL int *p = NULL;if (NULL = = p){}B, Use the assert function ASSERT (NULL! = p);C, with third-party toolsSecond, misuse of pointersMany security issues focus on buffer overflow, overwrite memory outside the bound

Now general security sites do not remember the password function, because remember the password has a security flaw.Regardless of the network interception problem, if the login page remember the password, the second login, directly into the developer mode to change the type of text to see the password.Processing method:1, the autocomplete= "off" attribute is added.2, the page uses the HTTPS protocol, becaus

When everyone is emphasizing how good html5 is, and all are focusing on html5/css3, html5 is also exposed to several possible security issues, this is a series of complications behind html5's excellent standards, but it does not affect the impact of html5 standards on the future. We only need to know and prevent them.The following content does not use any special sequence. We will introduce five methods tha

Struts2 It is a multi-instance, for each request will generate 1 instances, spring by default is single-instance (below for struts and spring integration of two ways to introduce the two struts2 and spring integration method)One: For the integration of no spring plug-in (Struts2-spring-plugin-xxx.jar), you need to add the business logic controller class to the spring action Bean with scope= "prototype".Two : for the integration of

is also a bright spot, support JSR303, processing AJAX Requests is more convenient, just a note @responsebody, and then directly return the response text.Summarize:This also shows that SPRINGMVC and Servlets are thread-safe methods, so the private or public variables declared in the class method are not thread-safe, and struts2 is indeed thread-safe.Part IV: What about the struts2+spring to manage injection? Struts2 It is a multi-instance, for each request will generate 1 instances, spring by d

, the security issues of Ethernet switches have been paid more and more attention. At present, we need to deal with the following aspects: (1) broadcast storm attacks Assume that an extremely malicious user can send large-volume broadcast data, multicast data, or the target MAC address is a random unicast data. When the switch receives the data, it will be forwarded in broadcast mode. If the switch does not

$ _ SERVER variable and PHP use $ _ SERVER ['php _ SELF '] to obtain the current page address and its security issues. _ serverphp_selfPHP $ _ SERVER ['php _ SELF '] $ _ SERVER ['php _ SELF '] indicates the address of the current PHP file relative to the website root directory, which is related to document root. Suppose we have the following URL. The results of $ _ SERVER ['php _ SELF '] are: http://www.5id
