Introduction In enterprise networks, downtime is unacceptable. Whether you are protecting a hospital’s patient data, a bank’s financial records, or a defense network’s classified systems, Cisco ISE (Identity Services Engine) must be available 24×7 with zero disruption. A single node failure in an ISE cluster […]
Introduction Security Group Tags (SGTs) are the identity currency of Cisco TrustSec. Instead of binding policy to IPs/VLANs, ISE assigns an SGT (e.g., HR=10, Finance=20, Guest=30) to users/devices at authentication time. These tags travel (inline) or are distributed (via SXP) so switches, WLCs, and firewalls […]

Introduction Wireless NAC (Network Access Control) is one of the most critical security use-cases in enterprise networks. While wired NAC ensures endpoints connected via switches are authenticated and authorized, wireless NAC validation ensures every mobile, IoT, and BYOD device connecting through Wi-Fi is properly authenticated […]

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 […]
