Scalp: web log file analyzer to detect attacks

September 29, 2008

The tool Scalp written by Romain Gaucher detects attacks onto web applications by analyzing the Apache log files. This python script uses regular expressions from the PHP-IDS-Project to match attacks against PHP web applications. It is able to detect Cross-Site-Scripting (XSS), Cross-Site Request Forgery(CSRF) and SQL-Injection attacks, but as Apache does not save the variables from POST requests it is only possible to detect GET request attacks. Take a look at this example HTML protocol of the script. The program has no problem with some hundred Megabyte big apache log files, but you can also select a specific time period or kind of attacks. To use the analyzer you need to download the python script an the search pattern file.
