What role do switches and access points play in network security?

Switches and access points are critical components in a network that contribute significantly to its security. Their primary function is to connect devices within a local area network (LAN), allowing communication between them. However, their role extends beyond simple connectivity; they help to implement various security measures to safeguard the network.

For switches, they operate at the data link layer, managing traffic within the network. When properly configured, switches can segment network traffic, which minimizes the chances of unauthorized access and helps contain potential threats. For instance, features such as Virtual LANs (VLANs) can be used to separate different types of traffic, providing an additional layer of security against intrusions.

Access points, on the other hand, serve as the gateway for wireless devices to connect to the network. They typically employ security protocols such as WPA3 to encrypt wireless traffic, ensuring that any data transmitted over the air is protected from eavesdropping. Furthermore, modern access points may implement additional security measures like device authentication, which helps to ensure that only authorized devices can connect to the network.

In summary, the primary role of switches and access points in network security is to connect devices securely by implementing various security measures to protect the data transmitted across the network and to control access based on
