How Can i make sure that all OWASP related vulnerabilities are being blocked by our ASM policy?

Hi Nuruddin, It all depends on how you implement your policy. F5 got covered all the OWASP vulnerabilities in the signatures but you might need to tune your policy in way the negative security approach. But i would say you need to be in the middle of positive and negative security model - an applied security model. Both model has got good and band but it depends your organisational standard etc.
