ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx that is developed by Trustwave's SpiderLabs. It has a robust event-based programming language which provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis.

    When it comes to your application: I don't know how tech-savvy you are, and I'm not sure if you're worried about someone breaking into your webapp, but you could look into setting up security extentions like snuffleupagus (PHP) and SpiderLab's ModSecurity WAF for Apache and nginx for which OWASP has a great, free ruleset

    I would recommend mod security which can be installed as a module for most web services like nginx and apache (and is open source). You can use the OWASP ruleset with some additional wordpress specific rulesets.
  • AWS SQL Injection (?)
    1 project | | 9 Mar 2021
    Looks like the webserver has a Web application firewall installed (WAF). My would guess this Has nothing to do with AWS database per se, the WAF is running on the server along Apache, as a module. Log entry was triggered because an SQL injection attempt was detected and stopped. As it looks now the website is potentially under attack.
  • XSS: What it is, how it works, and how to prevent it
    1 project | | 18 Jan 2021
    It may seem like overkill, but there are web application firewalls designed to specifically prevent common web attacks such as XSS and SQL Injection. Using a web application firewall (WAF) is not necessary for most applications, but for applications that require strong security, they can be a great resource. One such WAF is ModSecurity, which is available for Apache, Nginx, and IIS. Check out their wiki for more information.

    Interesting work, I was going to implement for but your idea seems quite useful. I would remove logrus, as logs should be created by the implementation, not the library (or at least that's what a think)

    You have a point there, maybe releasing a v1.0 is not that crazy at all, it's much easier to type import "" indeed
