Introduction In today’s enterprise networks, a single SSID is rarely enough. Organizations often need multiple wireless networks (SSIDs) to segregate traffic and apply different security policies — for example, separating corporate devices, guests, IoT devices, and contractors. However, without a central policy engine, managing authentication, […]

Introduction Wireless networks today are the primary access method for employees, guests, and IoT devices — but without proper control, they’re a security nightmare. Users can connect from anywhere, rogue devices can piggyback on open Wi-Fi, and sensitive resources can be exposed in minutes.Wireless 802.1X […]
Introduction When deploying Cisco ISE in a real-world enterprise, authentication decisions often depend on multiple identity sources—like Active Directory (AD), internal ISE users, LDAP, or RADIUS token servers. But what happens when you need to query them in a specific order? That’s where Identity Source […]
