From a security standpoint, TCP and UDP ports on your system are divided into several groups
according to their probability of being used by an attacker. Attempts to access ports that are
assigned to vulnerable services like DCOM or RPC should be seen as serious indications that you
are being maliciously probed.

Vulnerable ports are divided in two groups: System and Trojan. System ports are vulnerable
because they are often open for everyday system services. Trojan ports are those known to be
exploited by Trojan horses.

We recommend paying special attention to the following ports:

* System: 0, 21-23, 25, 79, 80, 110, 113, 119, 135, 137, 139, 143, 389, 443, 445, 1002,
1024-1030, 1720, 1900, 5000, 8080

* Trojan: 21, 23, 25, 80, 113, 137, 139, 555, 666, 1001, 1025, 1026, 1028, 1243, 2000,
5000, 6667, 6670, 6711, 6776, 6969, 7000, 8080, 12345, 12346, 21554, 22222, 27374, 29559,
31337, 31338
