The proposed ModSec-Learn model uses the Core Rule Set (CRS) as input features to tune the contribution of each rule to predictions, adapting the severity level to web applications. This approach achieves a better trade-off between detection and false positive rates compared to traditional heuristic-based methods. The model can also reduce the number of relevant CRS rules by up to 30% using sparse regularization. By leveraging machine learning, ModSec-Learn overcomes limitations in detecting web attacks based solely on heuristics.

A new approach for protecting websites from malicious attacks is being proposed. Normally, protection systems use a set of predefined rules to detect and block harmful requests. However, these rules are not tailored to the specific website being protected. The new system uses machine learning to learn which rules are most important for each website. This results in better detection and fewer false alarms. The team also found that they could reduce the number of rules used by up to 30% without affecting performance.
