zt_int_006 — Front Door profile accepts TLS below 1.2¶
Summary
Severity: High · Pillar: Network · Chain role: AMPLIFIER
Description¶
Front Door profiles with minimumTlsVersion below 1.2 negotiate weak ciphers with older clients, giving MITM attackers downgrade-attack opportunity against every origin behind the profile. Front Door is a public-internet accelerator — the TLS floor must be 1.2.
