Varför finns det en stor mängd portavsökningsfilterposter i F-Secure- brandvägg blocks.log?

Issue:

Den här artikeln gäller följande F-Secure-produkter: F-Secure Client Security 14.x / 15.x, , F-Secure Server Security 14.x, / 15.x och Elements Endpoint Protection-produkter

Jag ser många av följande poster i brandvägg blocks.log:


[xxxx.xxxx]  I: Type: FWPM_NET_EVENT_TYPE_CLASSIFY_DROP. Dropped by filter: Port Scanning Prevention Filter, This filter prevents port scanning. This many times means there are no listeners. If debugging ensure your scenario has one.

Anslutningsparametrarna varierar, med olika lokala/fjärrportar och IP-adresser. Behöver jag ändra mina brandvägg för att dessa massage ska försvinna?

Resolution:

Dessa loggposter är kopplade till Stealth- lägesmekanismen i Windows-brandväggen med avancerad säkerhet. Det är en inbyggd funktionalitet som tyst släpper utgående ICMP-meddelanden som inte går att nå och TCP-återställningsmeddelanden för att förhindra portskanning. Denna funktion reagerar när det inte finns någon process som lyssnar på porten, som riktas mot den inkommande begäran/trafiken.

Du kan läsa den här Microsoft Technet- artikeln för mer information om den här funktionen.
