Taking first steps in the security world.
I know that a 'firewall' is nothing but a configuration file for iptables, but that's about it.
I need recommendations for literature or other sources of reliable knowledge that start off with answers to questions such as: 'What is a port?'
Any time and trouble appreciated.
Religion is regarded by the common people as true,
by the wise as false,
and by the rulers as useful.
— Lucius Annæus Seneca.
Terrorism, the new religion.
