Simple security question

[Collins Richey]

Simple security question.  I don't do anything special for security, but I got curious enough to issue `lsof -i` just for grins.


COMMAND  PID USER   FD   TYPE DEVICE SIZE NODE NAME
lpd      997   lp    6u  IPv4   2805       TCP *:printer (LISTEN)
wdm     1146 root    4u  IPv4   3243       UDP *:xdmcp 
wdm     1146 root    5u  IPv4   3244       TCP *:32768 (LISTEN)
X       1149 root    1u  IPv4   3249       TCP *:6000 (LISTEN)
wdm     1150 root    5u  IPv4   3244       TCP *:32768 (LISTEN)

Given the few ports that are actually listening, do I have much to worry about?
