Redis requires much memory reserved memory for security issues, redis memory usage I have tried to limit the memory usage of apsaradb for redis by setting it. The result shows that it is not feasible. (Redis does not distinguish between cold and hot data and keeps cold data on the hard disk ). If you want to run redis normally, you need to know how much memory redis can occupy and how much memory it retain

Method One:COMODO The default update server has only one: http://download.comodo.com/my telecom network update speed is very slow;There is really no way to find a few update servers:http://eu1.download.comodo.com/http://eu2.download.comodo.com/http://eu3.download.comodo.com/Add these servers to (General settings, update-to-agent and host settings) add them to the line; the speed is OK, there is no problem of update failureMethod Two (method fast):There is another way is to download the offline u

$_server[' php_self ', some programmers tend to use the following method when submitting form data to the current page for processing:Assume that the page address is:http://www.5idev.com/php/index.phpTo access this page, get the form HTML code as follows:This code is correct, but when the access address becomes:Http://www.5idev.com/php/index.php/test/fooThe page executes properly and the form HTML code becomes:Obviously this code is not what we expected, and the attacker could arbitrarily add t

In JSP, we often use string Str=request.getparameter ("St"), this way to get the value, and then introduce the Var str=So write: String Str=request.getparameter ("St"); Request.setattribute ("str", str); When you accept Var str=${str}, you can avoid this security vulnerability.Security issues caused by nested JSP page values passed in JS code

Summary: The key judgment, compare as far as possible use = = = Type and value comparison of the identity comparison1.if ($var) $var follows the Boolean conversion.When converted to Boolean, the following values are considered FALSE : The Boolean value FALSE itself Integer value 0 (0) Floating-point value 0.0 (0) An empty string, and the string "0" An array that does not include any elements Objects that do not include any member variables (PHP 4.0 only applies)

Input string where all PHP considers int is cast, such as $a'asdfgh'；//字符串类型的aecho$a[2]； //根据php的offset 会输出'd'echo$a[x]； //根据php的预测，这里应该是int型，那么输入string，就会被intval成为0 也就是输出'a' If switch is the case of a numeric type, switch converts the arguments in it to the int type. As follows: $i ="2abc";switch ($i) {case0:case1:case2: echo"i is less than 3 but not negative"; break;case3: echo"i is 3";} Loosely-compared tables '). addclass (' pre-numbering ').

Accidental attention to database security issues, as follows One table ID field primary KEY self-increment If you want to delete a piece of data So "Delete from Test where id=". $_post[' ID '] The question is, is it possible that this is not safe? "Delete from Test where id=". $_post[' ID '] $_post[' id '] = 2 or 1=1 situation Will this happen, causing all of the deletions to occur? ------So

NotificationRecord{40dacad8 pkg=com.htc.android.psclient id=7f020010 tag=null pri=100} Then extract the package name. Here, the regular expression is used to extract the package name. If you want to know the regular expression, you can refer to my regular expression tutorial. Getting started with regular expressions (Java) The execution result here is (it seems that two notifications are prompted for one application) app:pkg=com.zdworks.android.toolboxapp:pkg=com.zdworks.android.toolboxapp:pkg=

In order to avoid repetitive execution of tasks in Java multithreaded execution, shared member variables can be processed through the Synchronized keyword, with the following code: //Multithreading task Method　　Private voidProcessmultitask (FinalListintThreadCount)throwsException {　　　　　Process Task List based on number of threads set　　　　 for(inti = 0; i ) {Taskthread thread=Newtaskthread (list); Thread.Start (); } }　　//Task Processing thread class classTaskthreadextendsThread {Private

As we all know, the traditional session data is stored in the file, so that, to a certain extent, reduce the speed.Before we implement the problem, the php.ini should be configured as follows:Session.save_handler = memcache //Specify to save data using memcachedSession.save_path = "tcp://127.0.0.1:11211" //connection to specify session dataSometimes you can also use Ini_set ("key", "key value") to set the php.ini operation configuration.When we want to take out, the key should be the session ID,

Before I wrote some of the Android phone root security issues (see the end of the article list), in fact, I was thinking of where to write, today to clean up the hard drive, found a year ago wrote a piece of code, so today we will discuss together.Note: This is not a technology to talk about NB, but someone who wants to understand the risks of Android knowing where we are.

The servlet itself does not have an issue with the so-called thread security, depending on how we use the servlet. With the Tomcat Web container example, the servlet is loaded with a single instance in the container, and since the container is definitely running in multi-threaded mode, if the servlet uses static variables or instance variables, then it is certainly thread insecure. In order to ensure thread safety in high concurrency, the first prere

We know that the development of networks is inseparable from the sharing of resources. In this case, we use the NFS protocol for sharing. Pay attention to the security issues of NFS servers. NFS is short for Network File System. It is an integral part of a distributed computing System. It can share and assemble remote File systems on Heterogeneous Networks. Developed by Sun, NFS has become a standard for fi

organizations as a new brand. If the supplier you are considering does not have relevant security qualifications or cannot provide adequate security protection, you should know that your documents cannot be secured. 3. Is the plug-in more secure than the execution program itself? Because the plug-in can obtain the trust and permissions of the execution program, you may think that the plug-in is not as expo

I believe you have heard more or less about various Web application security vulnerabilities, such as cross-site scripting (XSS), SQL injection, and upload vulnerabilities ...... Diverse. Here, I do not deny the naming and classification methods, nor comment on the rationality of the naming. What I want to tell you is that among the various security vulnerabilities, in fact, there are only a few

ASP. NET Forms verification is mainly used to prevent Forms from being cracked and endangering website security. Today, we will start with simple Forms and explain the consequences of the crisis. ASP. NET provides built-in login authentication, the most common is Forms authentication. There are many articles on how to configure and use this verification method. The following describes some of the security
