SecurityMultiTool-masterPHP Security Library is a set of advanced security layers that are easy to use, well-structured, fast and designed specifically for PHP-like web applications. This intrusion detection system does not provide any mitigation and anti-virus mechanisms, nor does it filter malicious input content. Its function is simply to identify malicious activities carried out by attackers against the site and provide timely reminders in the way that everyone needs. With a set of proven and very strict filtering rules, the detection system will give an impact rating value to any attack activity, helping users more easily understand how to respond to current hacker attacks. There are many ways to respond, including simply sending log records to the development team via an emergency email, displaying a warning message about the attacker, or even immediately terminating the user's current session.
