Puerto ICMP abierto

Ayuda Hacer una pregunta
Hola

He probado a hacerle un scan de puertos a mi máquina con el SP2 y me he
encontrado, con el ICMP abierto, cosa que antes no me pasaba con el SP1

He usado la página http://scan.sygate.com seccion quick scan

Po rlo que he visto en la configuracion del firewall de windows, eso se
refiere a solicitud de eco entrante que esta habilitada por defecto (no me
lo deja modificar).


Mi pregunta es si me debo preocupar por este tema



Service Ports Status Additional Information

ICMP 8 OPEN An ICMP ping request is usually used to test Internet
access. However, an attacker can use it to determine if your computer is
available and what OS you are running. This gives him valuable information
when he is determining what type of attack to use against you

Y estos son los resultados del stealth scan, que cuando tenía el SP1 daban
todos "blocked"


Debería de preocuparme?

Saludos y gracias
