"A Firewall monitors incoming and outgoing network traffic and either allows or denies it, based on a set of preconfigured rules. When a Firewall is enabled, your system is much more secure than when it's disabled."
"Stealth Mode ensures that your Mac doesn't respond to either 'ping' requests or connection attempts, which can be a first step in an attempted break-in."
Firewalls are crucial for network security, monitoring traffic and enforcing rules. Macs often ship with the Firewall disabled, making them vulnerable. Stealth Mode enhances security by preventing responses to ping requests and connection attempts, which hackers use to probe networks. Enabling both features significantly increases protection against potential intrusions. Users should prioritize these settings to safeguard their devices, especially when connected to networks.
