CCNP Security 300-715 Passing Score

The pxGrid persona provides the context-sharing framework required for Cisco ISE to exchange security information with other Cisco and supported third-party platforms. Through pxGrid, integrated products can publish or subscribe to contextual data such as user identities, endpoint details, session information, security group tags, and applicable security policies. This enables firewalls, threat-detection systems, management platforms, and other security tools to make access-control or investigation decisions using identity and TrustSec context obtained from ISE. SXP is a protocol for propagating IP-to-SGT mappings between TrustSec-capable or TrustSec-aware devices; it is not an ISE node persona and does not provide general policy-object sharing. The Policy Service persona evaluates authentication and authorization requests. Identity Mapping is a contextual function rather than the integration persona required to provide scalable, bidirectional information sharing with multiple security products.
