Question on Ports to know

republic001

Hello All,

First off, I just want to say how awesome this site is!!! The notes for Security have really helped in my studies!!!

My question is on the quiz for the port numbers, is that all the port numbers we need to know? I don't have any trouble learning them since I just passed my Network exam and the majority of the port numbers are the same. I just want to know so I will be prepared. The ones listed were SNMP, Kerberos, DNS, TFTP, NNTP SSH PPTP HTTP Telnet, IMAP, POP3 ICQ/Yahoo Messanger, L2TP, RADIUS, HTTPS, FTP, SMTP, SNMP traps, LDAP, AND TACACS.

btw thought this was funny, using Symbex study book and the cd included on it had a trojan horse on it. Thank goodness my pc tools picked it up.

I'd go through the list up to 1024 and make note of all the ones that seem important. You obviously don't need to know all of those, but a decent number of them should jump out at you as being important from your studies. It looks like you're missing IPSec from that list, just at first glance.
