is only an aid
The desire for automation adds many new features to popular vulnerability scanners, such as the Acunetix Web vulnerability scanner (which is good at cracking passwords in Web applications) and Metasploit Pro (which can be used to obtain command prompts and create Backdoor programs ).
But even these tools cannot completely automate the process. For example, using Metasploit Pro, IT must first run a vulnerability scanner (such as Nexpose or Nes
Bugscan (bugscan.net) is a scanning platform for B/S segments recently developed by a Chinese god. You only need to set up a python environment locally to scan your website in an all-round way, the new scanner also provides plug-in APIs to allow users to write plug-ins themselves and share the plug-ins with users. Small make up local test, scanning speed and results are very powerful, especially the crawler is very in place.The original text is as follows:There are a wide variety of scanning sof

2. determine all possible input methods
There are many user input methods for Web applications, some of which are obvious, such as HTML forms. In addition, attackers can interact with Web applications through hidden HTML form input, HTTP header, cookies, and even invisible backend AJAX requests. In general, all http get and POST requests should be user input. To find out all possibl
specifications can always be reflected in Tomcat. Because of the advanced Tomcat technology, stable performance, and free of charge, Tomcat is favored by Java enthusiasts and recognized by some software developers. It has become a popular Web application server.
7.2common software for Web Server Vulnerability attacks
(1) The Metasploit framework is an open-source platform for development, testing, and startup of attack code. We can use it to develop attack code or use the provided code to lau
scans, including Nessus and OpenVAS, although they have some limitations compared with paid tools.Another important part of threat detection security analysis is log management. Our idea is to store all system log information in a centralized security location for future use. When an attacker intrude into the system, he or she usually deletes the Intrusion Evidence by editing or deleting the system logs. Transferring these logs to the central reposit
for a specific vulnerability. Call the service detection plug-in to check services with different TCP/IP ports on the target host, save the results in the information library, call the corresponding plug-in program, and send the constructed data to the remote host, the detection results are also stored in the information library to provide the required information for other script operations, which improves the detection efficiency. For example, in an FTP service attack, you can first view the
