Miksi F-Securen palomuuri blocks.logissa on suuri määrä porttitarkistuksen estosuodatinmerkintöjä?

Issue:

Tämä artikkeli koskee seuraavia F-Secure-tuotteita: F-Secure Client Security 14.x / 15.x, , F-Secure Server Security 14.x, / 15.x ja Elements Endpoint Protection -tuotteet

Näen palomuuri blocks.logissa paljon seuraavia merkintöjä:


[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.

Yhteysparametrit vaihtelevat paikallisten/etäporttien ja IP-osoitteiden mukaan. Pitääkö minun muuttaa palomuuri , jotta nämä hieronnat katoavat?

Resolution:

Nämä lokimerkinnät liittyvät Windowsin lisäsuojauksella varustetun palomuurin Stealth mode -mekanismiin. Se on sisäänrakennettu toiminto, joka poistaa äänettömästi lähtevät ICMP:n tavoittamattomat viestit ja TCP-nollausviestit porttitarkistuksen estämiseksi. Tämä toiminto reagoi, kun portissa ei ole prosessin kuuntelua, johon saapuva pyyntö/liikenne kohdistuu.

Lisätietoja tästä toiminnosta on tässä Microsoft Technet -artikkelissa .
