I'd rather not do that. There are recipes that I keep for my customers. At least for now. And then at the end you evaluate the variable - or two separate variables in your case. Ahoj, Christian Good explanation. Ahoj, Christian -- Anyone who takes himself too seriously always runs the risk of looking ridiculous; anyone who can consistently laugh at himself does not.
I do not see any conceptual problem to use multiple variables to track violations. One for the final blocking action and one for the final log-only action. Best, Christian Christian, could you post an example of this? Hey Ed, The way I write the whitelisting rules I use in production is that I separate the rules from the action.
ModSecurity 2. This book teaches ModSecurity from the beginning to anyone with basic Linux skills. It starts by focusing on introducing ModSecurity, and explaining the concept of ModSecurity rules and how to write them. Later, it looks at the performance of ModSecurity and what sort of impact ModSecurity has on the speed of your web application.
This book is written for system administrators or anyone running an Apache web server who wants to learn how to secure that server.
It assumes that you are familiar with using the Linux shell and command-line tools, but does its best to explain everything so that those who are not Linux experts can make full use of ModSecurity Stored procedures are compiled T-SQL statements that reside on the database. Before starting the compilation process, make sure that you have all the dependencies in place.
We strongly recommend the utilization of the unit tests and regression tests. Details on distribution specific builds can be found in our Wiki: Compilation Recipes. All others dependencies are related to operators specified within SecRules or configuration directives and may not be required for compilation. A short list of such dependencies is as follows:. If those libraries are missing ModSecurity will be compiled without the support for the operator detectXSS and the configuration directive SecRemoteRules.
The library documentation is written within the code in Doxygen format. This will generate HTML formatted documentation including usage examples.
Inside the subfolder examples, there are simple examples on how to use the API. Below some are illustrated:. You are more than welcome to contribute to this project and look forward to growing the community around this new version of ModSecurity. Areas of interest include: New functionalities, fixes, bug report, support for beginning users, or anything that you are willing to help with.

Pull requests can include various commits, so provide one fix or one piece of functionality per commit. Please do not change anything outside the scope of your target work e. Provides explanative commit messages. Patch explanation is valuable during the review process. Check the list of items by performing a grep:. Along with the manual testing, we strongly recommend you to use the our regression tests and unit tests.
If you implement anything else, it is encouraged that you develop complimentary regression tests for it.
The regression test and unit test utilities are native and do not demand any external tool or script, although you need to fetch the test cases from other repositories, as they are shared with other versions of ModSecurity, those others repositories git submodules.
To fetch the submodules repository and run the utilities, follow the commands listed below:. Before start the debugging process, make sure of where your bug is. The problem could be on your connector or in libmodsecurity. Print Book Look Inside. The topics covered include: Installation and configuration of ModSecurity Logging of complete HTTP traffic Rule writing IP address, session, and user tracking Session management hardening Whitelisting, blacklisting, and IP reputation management Advanced blocking strategies Integration with other Apache modules Working with rule sets Virtual patching Performance considerations Content injection XML inspection Writing rules in Lua Extending ModSecurity in C The book is suitable for all reader levels: it contains step-by-step installation and configuration instructions for those just starting out, as well as detailed explanations of the internals and discussion of advanced techniques for seasoned users.
