Firewalls can be divided into several different security levels. In Linux, because there are many different firewall software options, the security can be low and high, and the most complex software can provide almost no penetration protection capabilities. However, the Linux core itself has a simple mechanism called "Disguise". Apart from the most specialized hacker attacks, it can withstand the vast majority of attacks.
