static page after the activity ends, Inform the routing server that it is not routed to this server (this is worth discussing ). M/n * (1 + 0.1) people who come in from all product servers will be forwarded to one payment server. when the payment process starts, the number of people will be small, locking is simple. Solution 3: Use the Memcache lock to implement a single server. Product_key is the key of the ticket Product_lock_key is the ticket lock key. When product_key exists in memcached,

recovering normal data to ensure reliable transmission of data information. The main protocol used in this protocol layer is TCP. This protocol can be used to create end-to-end one-sentence communication. However, the data information in the transport layer mainly depends on the effective Services provided by the network layer, which is greatly affected by the network layer.(5) Security Analysis of application layer protocols. The application layer contains a program for users to directly inter

filtering, because the method of filtering keywords has many vulnerabilities. Attackers can construct the following attack code: here, the keyword is blank, and the Tab key is precisely split, the above code becomes invalid again, so you may consider filtering tabs and spaces to prevent such cross-site attacks.4. Complete prevention of cross-site HTML attributesEven if the program designer thoroughly filters out a variety of dangerous characters, it

Comments: Video card mining virtual currency bitcoin is far more efficient than CPU. If you are a 3D game player and just hit the bitcoin mining Trojan, you will find it very choppy during the game. Here we will share with you a simple prevention method for bitcoin mining Trojan. Now the price of Bitcoin has risen very high, so there are hackers dedicated to create mining Trojans to induce netizens, so as to control the graphics card on the computer

Prevention of CSRF for Web Security Cross Site Request Forgery (Cross-Site Request Forgery) is a type of network attack, the attack can send a request in the name of the victim to the attacked site without the victim's knowledge, so that the operation under the permission protection is performed without authorization, it is harmful. Php csrf Guard function csrfguard_generate_token($unique_form_name){if (function_exists("hash_algos") and in_array("sha5

is, each operator in their own export router to authenticate the source IP address, if in their own routing table does not have to the packet source IP routing, the package is discarded. This approach can prevent hackers from using bogus source IPs for DDoS attacks. But again, this will reduce the efficiency of the router, which is the backbone operators are very concerned about the problem, so this practice is really difficult to adopt.The research on the principle and coping method of DDoS ha

XSS vulnerability attack and prevention methodsXSS is also called the CSS Tutorial (cross site script), Cross-site scripting attacks. It means that a malicious attacker inserts malicious HTML code into a Web page, and when the user browses to the page, the HTML code embedded inside the Web is executed to achieve the special purpose of maliciously attacking the user. SOURCE page put a label, in the background page_load inside write This.textlabel.text

HTTP attack and PHP security configuration prevention 1. What is security? The so-called security means to protect web applications and webpages from hacker attacks. Some hackers intrude into others' computers purely for fun, but more hackers are struggling to steal confidential files from others' computers, or even paralyze the entire computer to achieve his goal. There are a lot of software on the Internet that can be used by hackers. most of these

-free pool before creating an object inside a function. The first sentence of the function creates an auto-free pool that, when created, is appended to the release pool stack _releasepoolstack. And because another normal object is created with another autorelease () function, this function adds the newly created object to the auto-release pool (the newest one) we just created.When the scope ends, the destructor for the object is called, and the scope of the newly added auto-free pool is ended, s

the intranet, such as 10.0.0.0, 192.168.0.0, and 172.16.0.0, which are not fixed IP addresses for a network segment, but are reserved regional IP addresses within the Internet and should be filtered out. This approach does not filter the access of internal employees, but it will also reduce the number of fake internal IP filters that are forged during the attack, which can mitigate DDoS attacks.(8) Limit syn/icmp traffic (keep it up for a long time)The user should configure SYN/ICMP maximum tra

SQL injection usually occurs because the syntax is not rigorous, the problem occurs on the SQL statement, and the decisive is quote ('). As follows:$sql = "delete from table where id ='$id'" ;The normal commit is to delete a piece of data, if the ID is submitted (1 ' or 1 #), then the SQL statement becomesdelete from table where id = '1'or 1 #';In this way, the entire table will be deleted, resulting in irreversible results.Since the problem appears on the quote, just escape it (\ ') P

Flash playback software. The core of file bundling is to bind a normal file with a Trojan file. When bundling, the file icon will be modified to prevent such files from being opened to control the computer or spread viruses. 3. Application Software vulnerability Exploitation Technology The trojan program created by exploiting application software vulnerabilities is difficult to identify and has the highest risk.

, so they can defend against the crazy attacks of hackers. Some new network users do not have to worry, because many network security solutions and various firewalls have been launched on the market. I believe that in the near future, the Network must be a secure information transmission media. In particular, network security education should be put at the top of the entire security system at all times, and efforts should be made to improve the security awareness and basic

Thoughts and conclusions on XSS prevention I recently read some web security-related articles, most of which have systematic and complete solutions. However, XSS (Cross-site scripting) attack-related information is messy, even the XSS attacks where HTML object escaping can solve are unclear. After turning over a bunch of materials, I thought I 'd better record some of my thoughts on it. Note that there are different ways to avoid XSS:Text section of t
