21 Detecting Rogue Systems Unprotected systems are often the weak spot of any security strategy, creating entry points through which viruses and other potentially harmful programs can access your network. Even in a managed network environment, some systems might not have an active McAfee Agent on them. These can be systems that frequently log on and off the network, including test servers, laptops, or wireless devices. Rogue System Detection provides real-time discovery of rogue systems through the use of a Rogue System Sensor installed throughout your network. The sensor listens to network broadcast messages and DHCP responses to detect systems connected to the network. When a sensor detects a system on the network, it sends a message to the ePolicy Orchestrator server. The server then checks whether the system has an active agent installed and managed. If the system is unknown to the McAfee ePO server, Rogue System Detection provides information to ePolicy Orchestrator to allow you to take remediation steps, which include alerting network and anti-virus administrators or automatically deploying an agent to the system. In addition to Rogue System Detection, other McAfee products, like McAfee Network Access Control, add detected systems control to ePolicy Orchestrator.

Detecting Rogue Systems
Unprotected systems are often the weak spot of any security strategy, creating entry points through
which viruses and other potentially harmful programs can access your network. Even in a managed
network environment, some systems might not have an active McAfee Agent on them. These can be
systems that frequently log on and off the network, including test servers, laptops, or wireless devices.
Rogue System Detection provides real-time discovery of rogue systems through the use of a Rogue
System Sensor installed throughout your network. The sensor listens to network broadcast messages
and DHCP responses to detect systems connected to the network.
When a sensor detects a system on the network, it sends a message to the ePolicy Orchestrator
server. The server then checks whether the system has an active agent installed and managed. If the
system is unknown to the McAfee ePO server, Rogue System Detection provides information to ePolicy
Orchestrator to allow you to take remediation steps, which include alerting network and anti-virus
administrators or automatically deploying an agent to the system.
In addition to Rogue System Detection, other McAfee products, like McAfee Network Access Control,
add detected systems control to ePolicy Orchestrator.

What are rogue systems
Rogue systems are systems that access your network, but are not managed by your McAfee ePO
server. Unprotected systems are often the weak spot of any security strategy, creating entry points
through which viruses and other potentially harmful programs can access your network. Even in a
managed network environment, some systems might not have an active McAfee Agent on them. These
can be systems that frequently log on and off the network, including test servers, laptops, or wireless
devices.
A rogue system is any device on your network with a network interface card (NIC). On systems with
multiple NICs, each resulting interface is identified as a separate system. When these interfaces are
detected, they appear as multiple rogue interfaces.
