Most people are worried about database security issues! Generally, the database suffix is complicated and the suffix is. ASP. But is it absolutely safe! The answer is yes. It will never be safe! Because once someone guesses your path, you can use the database to download this name!Someone uses it again #*. asp is used as the storage method of the database, because according to the encoding principle of IE,

problem. So what if we had the wretched input of JavaScript code?The effect is very obvious, for examplewatermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvawjletbuza==/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/southeast ">What about the other JavaScript code we're typing? For example, to obtain a client's cookie, etc... are capable of.Suppose you think these are too chicken, that assumes the direct input of an embedded JS outside the chain? Suppose there is some code in the ou

What is the vulnerable JavaScript libraryThe Fragile javascrpts LibraryI didn't get a detailed explanation on the Internet either.In my understanding this method is to replace the use of JS Library, or modify the relevant JSMedium prob

performance.So when using, if multiple threads are working on the same object, use a thread-safe vector, or use a more efficient ArrayList.Non-thread safe! = is not secureSomeone in the process of using an incorrect point of view: My program is multi-threaded, can not use ArrayList to use the vector, so it is safe.Non-thread-safe is not available in multithreaded environments. Notice what I've said above: multithreading operates on the same object. Note that it is the same object. A arraylist o

code block when asleep, at this time thread 2 executed, but thread 2 in the encounter synchronized , to determine the synchronization lock is not in, the synchronization lock thread 1 hands, Threads 2 can't get sync lock, no sync code block key, Can not go in synchronization execution, is blocked in the synchronization code block outside, only waiting for thread 1 to wake up the synchronization lock back to synchronized , at this time, thread 2 has the opportunity to get the key (= Lock) into t

This article mainly describes the common attack methods for PHP websites, including common SQL injection, cross-site attack types. Several important parameter settings of PHP are also introduced. The following series of articles will stand in the attacker's perspective, revealing PHP security issues for you, while providing a corresponding solution.The following are the main types of attacks for PHP website

(). Format (date); public static Date Parse (String strdate) throws ParseException { return GetDateFormat (). Parse (strdate); } }Description: Using threadlocal, the shared variable is also changed to exclusive, the thread exclusive can be compared to the method exclusive in the concurrency environment can reduce the cost of many objects created. This approach is generally recommended if performance requirements are high.4. Discard the JDK and use the time formatting classes from

authorization cookie in the POST request body or URL, the request must come from a trusted domain because the other domain cannot read the cookie from the trusting domain. Contrary to the usual trust idea, using post instead of the Get method does not provide effective protection. Because JavaScript can use forged post requests. Nonetheless, requests that cause "side effects" to security should always be sent using post. The Post method does not leav

Recently has been doing location configuration, encountered priority issues (if the improper configuration may exist security risks OH), the following is a personal learning experience. Location of one or more matches1. Equals matching character: =equals the equals sign, which can be summed up to two points:Exact matchRegular expressions are not supported2. Null matching characterAn empty match is characte

PHP gives developers a great deal of flexibility, but this also poses a potential risk to security issues, the recent need to summarize the past problems, here to lend a translation of an article at the same time with their own development of some feelings summed up. Brief introduction When developing an Internet service, you must always keep in mind the concept of secu
