Introduction Welcome to Day 112 of the Cisco ISE Mastery Training, where we step into one of the most advanced integrations in the modern Zero-Trust ecosystem — FMC (Firepower Management Center) Automation via pxGrid. In today’s cyber battlefield, time is your greatest enemy. A malware-infected […]
Introduction In modern enterprise security, the days of static firewalls and isolated NAC enforcement are long gone. Today’s threats are adaptive, user devices are mobile, and applications live everywhere — from on-premises data centers to SaaS platforms. This demands dynamic, context-aware enforcement, where security decisions […]
Introduction “Today we wire real-time threat response: when FMC/FTD, Secure Endpoint (AMP), or Stealthwatch flags a compromised host, ISE auto-quarantines it over the network. We’ll use pxGrid for secure event and identity exchange, and ANC for enforcement (dACL / SGT / VLAN). You’ll leave with […]
Introduction Cisco Identity Services Engine (ISE) and Firepower Management Center (FMC) form a powerful threat-centric NAC ecosystem when integrated via pxGrid. But here’s the reality: In production, engineers often struggle with cert trust failures, pxGrid client not connecting, SGT not being seen in FMC, or […]
Introduction In Cisco ISE Device Administration (TACACS+), the Shell Profile is the authority that decides what execution context the admin receives at login—their privilege level, role(s), and any vendor-specific attributes the device needs to correctly shape the session. If Command Sets are your surgical “allow/deny” […]
Introduction An ISE upgrade touches every control path—RADIUS/EAP, pxGrid, portals, TACACS+, ERS/Sponsor, logging—and any mistake can drop authentications, cut integrations, or corrupt data. This workbook is a hands-on run book to execute upgrades with zero/near-zero downtime, using both GUI Split Upgrade and CLI Full/One-shot methods, […]
Introduction When an ISE node (PSN, MnT, PAN) fails, is end-of-life, or needs a hardware refresh, you must replace it without breaking 802.1X, posture, guest/BYOD portals, or pxGrid. This Article teaches you the repeatable, zero/near-zero downtime workflows to drain, remove, rebuild, rejoin, re-certify, re-sync, and […]
Introduction Policy Sets are the traffic control tower of Cisco ISE. They decide how to authenticate and what to authorize for each session—wired, wireless, VPN, or device admin. “Advanced” means you’ll leverage compound conditions, policy inheritance, result elements (dACL, VLAN, SGT, URL-redirect), profiling & posture, […]
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 Cisco TrustSec (CTS) is a next-generation access control framework that goes beyond traditional IP-based segmentation. Instead of relying on static VLANs and ACLs, it leverages Security Group Tags (SGTs) to dynamically classify traffic, enforce policies consistently across the enterprise, and scale security for modern […]
