CEH- Do i need to remember the ports?

khurramkhan

hi
being in IT for a long time, everyone knows common ports. my question is about ports like 7777 for Tini. Do we need to remember all ports for trojans, backdoors, RATs etc?

regards

It's 125 questions and covers a lot of ground. You might get a question or 2 or 3 that relies on knowing a common port for a trojan, but knowing this stuff isn't pass/fail on its own. It's probably more important that you recognise common ports for services, the port ranges (registered, well-known, dynamic), since that's easier to learn and helps across a few areas.

The exam information isn't really, really, really detailed, but it does give you a better indication than many exams of how many questions on what to expect.
