The Cisco Adaptive Wireless Intrusion Prevention System (wIPS) solution adds the Enhanced Local Mode
(ELM) feature, allowing administrators to use their deployed access points (APs) to provide comprehensive
protection without the need for a separate overlay network (Figure 1). Prior to ELM and in the traditional
Adaptive wIPS deployment, dedicated monitor mode (MM) APs are required to provide PCI Compliance
needs or protection from unauthorized security access, penetration, and attacks (Figure 2). ELM effectively
provides a comparable offering that eases wireless security implementation while lowering CapEx and OpEx
costs. This document only focuses on ELM and does not modify any existing wIPS deployment benefits with
MM APs.
