Currently, the vro technology has been very well developed. So I have studied how to use the vro technology to prevent malicious cyberattacks. I would like to share with you here and hope it will be useful to you. In addition to ADSL dial-up Internet access, residential broadband Internet access is also a common Internet access method. If you use residential broadband Internet access, Do you think vro technology is just an Internet tool? Otherwise, yo

This article introduces how Iptables limits the number of connections of the same IP address in linux to prevent CC/DDOS attacks. This is only the most basic method. If the attack is real, we still need hardware compaction to prevent it. 1. Set the maximum number of connections to port 80 to 10, which can be customized. The Code is as follows: Copy c

Native JS achieves carousel effects + pre-school experience (to prevent flooding attacks), and js gets mad Plug-in! Plug-in! I heard someone ask for this plug-in every day. Of course, using a third-party plug-in can greatly improve development efficiency. But as a newbie, I still like to implement it myself, mainly because I have time! Today, I will share with you how to use native JS to implement image car

PHP-Prevent XSS (cross-site scripting attacks)

If the client is making a request to the server-side interface, if the request information is encrypted, it is intercepted by a third party to the request packet, although the third party cannot decrypt the obtained data, but can use the request package for repeated request operation. If the service side does not carry out anti-replay attacks, the parameter server pressure increases, the consequences of data disturbance. You can solve this problem by

This method is used to passively analyze the nginx diary to find the IP address with a large number of requests and seal it with iptables.

This article describes in detail how to intercept TCP to prevent DOS attacks on CISCO routers. I hope this article will help readers learn about CISCO routers. 1) define an acl to protect the machine: Access-list 101 per tcp any host 202.106.0.20 Because there is no need to match the source address, generally dos is accompanied by address spoofing, so the source here is all any. 2) Enable tcp intercept
