What is an SSID?
An SSID is the identifying name associated with a wireless network, broadcast by an access point to make the network available to authorized clients.
Each SSID represents a logical network and can be configured with its own authentication methods, firewall rules, and access policies. It is common for organizations to use multiple SSIDs to segment networks for staff, guests, IoT devices, or critical systems.
Technical Aspects:
- An SSID can be hidden to reduce exposure in public environments, but this should not be confused with real security.
- Multiple access points can share the same SSID to allow seamless client roaming in larger wireless networks.
- SSID configuration is typically managed through a centralized controller to ensure consistency and policy compliance.
Use Cases:
- Segregating networks for employees, guests, and devices
- Providing secure WiFi access in offices, campuses, and industrial sites
- Supporting redundancy and seamless mobility in enterprise environments
