Now that there are many PHP development frameworks that provide filtering for XSS attacks, here's

This article mainly introduces how to use SCE in AngularJS to prevent XSS attacks and prevent cross-site scripting vulnerabilities by reasonably transcoding to HTML, for more information about the XSS (Cross-Site Scripting) solutions and how to use the SCE ($ sceProvider) and sanitize service features in AngularJS to correctly process XSS, see this article.

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. To actively limit the number of ip connections, refer to using nginx to limit the number of IP connections to prevent CC attacks. #! /Bin/bash# Created by http://www.onovps.com www.2cto.comNum = 100 # Upper LimitCd/home/wwwlogsFor I in 'Tail access. log-n 1000 | awk '{p

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
