Authenticate Legitimate AI Agent Traffic with WAF
π This post introduces Web Bot Authentication (WBA) in AWS WAF Bot Control, a cryptographic, standards-based method for verifying automated agent identities using HTTP Message Signatures. It explains how asymmetric signatures and IETF drafts enable tamper-proof verification, the new WAF labels (verified, invalid, expired, unknown_bot, vendor, name, account), and how verified traffic is handled by default. The article also outlines deployment steps, supported rule group versions, monitoring guidance, and future registration APIs.
