iOS supporta un firewall integrato come fa macOS? Non vedo nulla al riguardo in Impostazioni.
La pagina 27 del White paper sulla sicurezza di iOS del settembre 2015 afferma che non esiste un firewall su iOS .
On other platforms, firewall software is needed to protect open communication ports against intrusion. Because iOS achieves a reduced attack surface by limiting listening ports and removing unnecessary network utilities such as telnet, shells, or a web server, no additional firewall software is needed on iOS devices.
