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

You can use the second url encoding. This is because it cannot appear, so it is also difficult to note busy here.However, substring ('R' from 1 for 1) can be us

Web applications generally use form-based authentication (as shown in Figure). The processing logic is to pass the user name and password submitted in the form to the background database for query, determine whether the authentication is successful Based on the query results. For web applications with LAMP architecture, PHP is used for processing logic, and MySQL is used for background databases. In this process, due to poor processing, many serious vulnerabilities may occur. Apart from weak pas

Example of modsecurity rule syntaxSecrule is a modsecurity the primary directive, which is used to create security rules. The basic syntax is as follows:Secrule VARIABLES OPERATOR [ACTIONS] VARIABLESRepresentative HTTP The identity item in the package that specifies the object that the security rule targets. Common variables include:ARGS(all request parameters),files(all file names), and so on. OPERATORrepresents an operator that is typically used to define the matching criteria for a sec

Label: # # # Phenomenon: When we injected, found that there are dogs, there is a waf, really my little heart is broken down!! However, many times still have to calm down to analyze the filter system exactly what parameters are filtered, how to bypass. Using the tamper in Sqlmap brings us a lot of anti-filtering script bypass. Hint "The entry has a dangerous character and has been intercepted" Tip "Please do not attempt to inject illegal characters in

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

I use the documentation comments of these 41 scripts to simply mark each of their functions, or as before, Google Translate and then manually polished. In fact, there are examples of document comments, look at a glance will probably know the effect,
