ModSecurity is a supporting module inside Apache web server,
which scans the incoming HTTP requests against some common web application attacks, e.g. SQL injection, XSS attacks, etc.
Notes: although the network of Website Solution equips with Snort NIDS (Network Intrusion and Detection System) and ModSecurity web application firewall, which provide added layers of security,
However, these modules cannot provide defense against all kind of attacks. Customer shall not see them as 100% secure.
For enhanced security, customer shall regularly update his/her own website PHP/MySQL application (e.g. WordPress, Joomla, OpenCart, Magento, PrestaShop, etc) to minimize the security threats.
No computer system can provide absolute security under all conditions.
