What is the function of Stealth Mode in a Mac system?

Stealth Mode is a feature in macOS that enhances a system's security posture by preventing it from responding to incoming probing requests from external sources. When Stealth Mode is enabled, the Mac will not respond to unsolicited connection attempts, which helps to minimize the risk of being detected by potential attackers trying to scan the network for accessible devices. This feature effectively makes the Mac less visible on the network, thereby reducing the chances of unauthorized access.

By blocking responses to these probing attempts, Stealth Mode helps protect the Mac from various types of network attacks, including port scanning and other reconnaissance efforts that could reveal vulnerabilities. It’s an essential component of a broader security strategy, designed to safeguard the machine from unauthorized access and potential threats.
