How does switch helps fore net work security problems?

Switches enhance network security by segmenting traffic within a local area network (LAN) and reducing the likelihood of unauthorized access. They use MAC address tables to forward data only to the intended recipient, minimizing the risk of eavesdropping. Additionally, advanced switches can implement features like Virtual LANs (VLANs) and port security to further isolate sensitive data and control device access. This layered approach helps protect against various threats, including man-in-the-middle attacks and broadcast storms.
