This section explains Application Rules service offered as part of Live Security Threat Intelligence. Application Rules are rules that are specifically designed to block attacks on known application vulnerabilities (many of them with CVEs) and are automatically updated. Customers can protect their applications from such vulnerabilities by enabling this service on their Controllers.
These rules are different from NSX Advanced Load Balancer’s Core Rule Set (CRS), where rules are protecting against generic attack classes.
Protection for known vulnerabilties for over 5000 applications such as wordpress, drupal, apache, and many more.
