Security in the SAN - Zoning Zoning separates a Fabric into multiple sub fabrics to control access to devices in the fabric. The sub fabrics can be organized geographically or logically. Zoning supports Security Policies, enables sharing of Physical Resources, segregates Users, and protects against malicious and accidental attacks and operating anomalies (i.e. idiot operators). Virtual Zoning (software zoning) - Sets up cooperation between initiators (servers) and the fabric Initiators follow device discovery protocol Name Space & Driver compliant architecture Fabric offers name server, and targets register or fabric discovers Management intervention defines zones Fabric name space "hides" devices outside of zone No routing enforcement in fabric Zones can overlap Based on port number or world-wide name Does not protect against malicious or accidental attack Hard Zoning (hardware zoning) - Hardware access control at port level Hardware enforced port-based routing Hardware enforced path selection Zones can not overlap Fabric enforces routing Rigid enforcement by hardware Protects against malicious and accidental attacks Prevents exploratory and denial of service attacks
