[ASM ]about Configure Attack Signatures

Probably those Attack Signatures set contain Attacks which are not specific to one type of Platform, OS or application.

Perhaps a better approach is to look what Attacksignatures these sets contain. Go to: Application security >> Attack Signatures : Policy Attack Signatures Filter on Systems Assigned Systems General Database / System Independant / Various systems

I would suggest to enable the default assigned Attack Signature Sets and add all sets relevant to your servers.
