Ich habe an meinem Computer einen Portscan durchgeführt und folgendes Ergebnis erhalten:

Your system ports are now being scanned and the results will be returned shortly...
Results from quick scan at TCP/IP address: 212.241.78.22

Ideally your status should be "Blocked". This indicates that your ports are not only
closed, but they are completely hidden (stealthed) to attackers.

Results from scan of ICMP at TCP/IP address: 212.241.78.22

Protocol Type Status Additional Information
ICMP 8 BLOCKED 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.

You are not fully protected:
We have detected that some of our probes connected with your computer.

Mit den Ergebnissen dieses scans bin ich grundsätzlich zufrieden da der größte Teil geblockt ist was heißt, dass ich eine Firewall benützte die meinen Rechner nach aussen hin abschirmt und ich somit einigermaßen sicher im Internet unterwegs bin.

Die beiden closed sind nicht weiter schlimm da das erste bei www bedeutet dass der Port über den ich im internetsurfe, also internetexplorer, geöffnet ist- dies muss so sein wenn ich surfe. Der 2. closed bei IDENT ist auch nicht so schlimm da dies ein standartdienst auf unis system ist.
