Internal passwords reset for firewall and other features

I'm looking for how to change the internal passwords for firewall reset, antivirus page, etc under the detailred setting screen in Norton Security. Is there just ONE password?...or one for each screen as a tampering deterrent?.........I'm looking how to change passwords as the way is not clear. I've undergone numerous hacking issues and use different screens to monitor hacking attemps and submissions.---- I'm not really a techie...just a finance guy that's had to learn the hard way....trial and error!!!
