This article will share with you two practical functions of php for implementing the blacklist and whitelist, namely the security IP detection function and the function for obtaining the client IP address, I will not talk nonsense here. This is a php function used to check whether ip addresses are illegal. it is applicable to the development of white list and blacklist functions. it is mainly used in api source restrictions and access restrictions. The code is as follows: /*** Security IP detec

', lastactivity =' $ timestamp ', fid ='". ($ fid = ""? 0: 1). "', tid ='". ($ tid = ""? ). "'Where sid = '$ sid '");If ($ onlinehold $ user_lastactivity $ timestamp-$ user_lastactivity> $ onlinehold ){$ Db-> query ("UPDATE $ table_members SET lastvisit = lastactivity, lastactivity = $ timestamp WHERE uid = '$ discuz_uid'", 'unbuffered ');}} Else {$ Ips = explode ('.', $ onlineip ); $ Db-> query ("delete from $ table_sessions WHERE sid = '$ sid' OR

This is a detection of IP is illegal PHP function, to adapt to the whitelist, blacklist function development, the main scenario applied: API source restrictions, access restrictions and so on. Copy Code code as follows: /** * Secure IP detection, support IP segment detection * @param string $ip The IP to be detected * @param string|array $ips white list IP or blacklist IP * @return Boolean true is in whitelist or blacklist, otherwise

Status quo analysis: Zhao Ming: website O M Manager Two questions are raised in the video: 1. Use security protection solutions to prevent attacks. 2. When an attack occurs, the system can promptly trigger an alarm, block the attack, and record the hacker behavior characteristics. The current website topology is as follows: Through the video, Zhi Zhaoming's website was attacked by hackers and changed. In the current website topology, there is only one Server Load balancer, which may be replace

Zero-day attacks and distributed denial of service (DdoS) attacks brought by increasingly large botnets, many small and medium-sized enterprises that use traditional security equipment are exhausted, and the active defense technology can effectively solve the security problems brought about by these aspects. Intrusion detection and defense system (IDS/IPS) is an active defense technology that installs them in key locations of the network and detects a

This article has shared 2 PHP for the implementation of the black and white list of practical functions, respectively, the security IP detection function and get client IP function, the comments explained very clearly, here I do not much nonsense. This is a PHP function to detect whether the IP is illegal, adapt to the whitelist, blacklist feature development, the main scenario applies to: API source restrictions, access restrictions and so on. The code is as follows: /** * Security IP detectio

Now you can extend the Network Access ControlNAC measure tool to many Network security devices and Network management tools. Extending the NAC policy measures to these devices can enhance access control while still allowing users and host identities to be used as part of every security and management tool. Integrating user and host identifiers into security and management points means creating firewall facilities that can identify, using identity detection and blocking or intrusion prevention sy

FireWall for network security products) Firewalls were the first to adopt Internet security protection products. However, during the application process, it is found that firewall products based on network port protection and packet filtering protection technology cannot effectively intercept application security (inWeb Applications). However, the firewall product is still not out of the security market, on the contrary, because of its powerful data forwarding capabilities, attack defense capabi

LAN. Therefore, unauthorized wireless access devices can be called illegal wireless access devices. It is precisely because of the portability of these wireless access devices that allow them to quietly lurk around or inside the LAN deployed by the enterprise as a spy. You can obtain confidential information transmitted in a wireless LAN by listening to various information in radio waves sent from a wireless LAN. Alternatively, you can use a wireless LAN to intrude into an enterprise LAN to obt

pieces of data took 15 s out of 20 s during the xmlrpc call. In order to further improve the response speed, and the source code for encryption and decryption is the code implementation of c ++, I thought that using c ++ to implement a PHP extension may be better, so I started to implement the PHP extension of rc4.Preparations for compiling PHP Extension 1 using C ++ First, obtain the source code of the php version of the Bastion host on the development machine and decompress it. yangshuofei

need to determine whether the user has performed this operation.In fact, it is to judge whether the user refreshes. Of course, you can set a flag in JS to determine, but this requires every page to be written.I chose to judge on the server side, but there is a small problem.I checked whether the Source Page and target page that I clicked last time were the same as the next page. If they were the same, I thought they were refreshed.The Code is as follows: Code Code highlighting produced by Acti

LCD TV Panel Typeone of the LCD TV panels: tn+film Viewing angle expansion film (soft screen )　　This technology is still based on the traditional TN-mode liquid crystal, but only in the manufacturing process to add a film coating process. Tn+film wide-angle technology is the most important feature is the low price, technology access threshold, widely used. In general, the TN panel is an obvious advantage and disadvantage of the product, the price is cheap, the output gray class number is less,

Problem:Ip! is not available to clients when processing client requests using the thread poolReason:Since the Server_loop note loop only adds the connection word sock to the queue, there is no client IP, so each queue callback function can only get sock connection word, no client IPWorkaround:In the queue sock joins the IP also added to the IPs queue, the IPs queue length and queue, and the data stored in t

level so that the backlight is passed faster, which can shorten the display time greatly, and also because the highlight changes the liquid crystal molecule to match, so that the angle of view is wider. The increase in the angle of view can reach more than 160 degrees, the reaction time shortened to less than 20ms. PVA Type: Samsung introduced a type of panel, is a vertical image adjustment technology, the technology directly changes the structure of liquid crystal units, so that the display p
