WAF Web Application FirewallThe Web application firewall is a product that is specifically designed to protect Web applications by executing a series of security policies for Http/https.Unlike traditional firewalls, WAF works at the application layer, so there is a natural technical advantage to Web application protection. Based on a deep understanding of the business and logic of Web applications,

Now, the market exists a large number of true and false Web application firewall products, the user's understanding of it is not clear enough, coupled with the industry's lack of Web application firewall measurement standards, Web application Firewall evaluation of the good or bad becomes very difficult. In fact, to choose a good Web application firewall is not difficult, the following aspects can be examined: 1. Attack interception capability The primary function of

When we get the target server, we usually use artifact Mimkaz to fetch the clear-text password of the target server, but if the target server is configured Waf,mimikaz cannot crawl, it is possible to download the DMP file with account password to local to use Mimikaz crawl.Realize the same system environment as the target machine. Then use the following command to download the DMP file;Procdump.exe-accepteula-ma Lsass.exe%computername%_lsass.dmpThis p

Common URL encodings include UTF (% xx) and hexadecimal encoding (% xx). Most IDS and WAF can be identified and decoded before regular matching. However, in addition to the two types of encoding, the IIS web server also supports another non-standard encoding, namely, % u Encoding (% uxxxx ). For more information, see the original document. I have to say that some technologies will not be old. The key is that you do not care. That is to say, the reques

Introduction:First of all, we should all know the function and principle of WAF, the market is basically using Nginx+lua to do, here is no exception. But slightly different, the logic is not in Lua.Instead of using Elasticsearch for analysis, LUA only uses the analyzed IP address to block, greatly reducing the direct interruption caused by false positives and other failures.The architecture diagram is as follows:You can get the following useful data:1
