Portscan:
Mit einem Portscan kann man feststellen, welche Ports an einem Computer (der ans Internet oder ein Netzwerk angeschlossen ist) "offen" sind.
Sonntag, 18.06.06 um 13:33 durchgeführt mit Hilfe der Sygate Website
[LINK]
Das Ergebnis:
die meisten Ports sind nicht nur "verperrt", sondern auch versteckt...
D.h. meine Firewall arbeitet sehr effizient.
Port 80 = Internet Port ist offen, sonst würde das surfen nicht einwandfrei funktionieren.
Port 113 = harmloser Port, der von einigen Firewalls nicht richtig konfiguriert wird.
Laut dieser Homepage
[LINK] besteht also keine Gefahr!

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.
