Port Security Insights

What is Port Security?

Port Security is a security feature on network switches that limits the number of MAC addresses allowed to connect to a specific port. It is commonly used to prevent unauthorized devices from accessing the network by learning and allowing only specific MAC addresses, discarding traffic from unknown MAC addresses, and potentially disabling the port upon violation.
