Inside PH4NTXM: #31 Firewall Supervision A firewall can be correct at boot and different five minutes later. PH4NTXM's normal-mode firewall guard polls the active ruleset every two seconds and compares its fingerprint with the expected state. Source rules are integrity-checked and syntax-checked before application, including the required NFQUEUE arrangement and disabled bypass behavior. A detected mismatch removes readiness and activates emergency Lockdown before restoration. Readiness returns after successful verification. This is ongoing, periodic supervision of the expected policy, giving Boot Pilot and Health a current protection signal instead of a one-time startup assumption. #ph4ntxm #linux #debian #os #live #privacy #security #opsec #infosec #research #tech #technology
