W—Write access. The data can be changed.
X—Execute. The data can be executed; for example, a directory can be viewed or program executed.
D—Delete. The data can be deleted.

Q26. Define the terms NetRanger Sensor and Director and their uses?
NetRanger Sensor—High speed device that analyzes the content of data being transported across a network and determines whether that traffic is authorized or unauthorized. Unauthorized traffic includes ping requests from intruders. Traffic that is detected from unauthorized sources is sent directly to the NetRanger Director, and the intruder is removed from the network (optional and set by network administrator).NetRanger Director—Provides real-time response to intruders in the network by blocking access to the network and terminating any active data sessions.
Q27. What LAN interfaces can be supported on a NetRanger Sensor?
Q28. What are the six phases completed by Cisco NetSonar?
Phase I—NetSonar sends out ICMP echo requests (ping) to query hosts.
Phase II—All live hosts are collected and stored on particular port numbers.Phase III—NetSonar identifies the hardware devices that might be vulnerable, such as routers, switches, firewalls, printers, desktops, and hosts that responded to ping requests. Operating systems and network services are documented and labeled as potential vulnerabilities.Phase IV—Vulnerabilities are confirmed. This phase is intrusive.
Phase V—The data is charted for presentation. The data can also be charted graphically as line or 3D bar graphs.
Phase VI—The data is reported in a number of different formats, including a summary report, a short and detailed report, or a full technical report.
Q29. What is the meaning of the term Security Wheel?
Answer: Cisco defines a Security Wheel concept that outlines the critical steps to ensuring that data and networks are secured correctly. The Security Wheel revolves around a strong, well-defined corporate policy. The Security Wheel consists of the following:
Secure—After defining a strong corporate policy, you should secure your network by deploying the products necessary in the appropriate places to achieve your corporate security policy.
Monitor and respond—Continuously monitor using NetRanger tools at strategic points in the network to discover new vulnerabilities.
Test—On a regular and formal basis, test all network components.
Manage and improve—Analyze all the reports and metrics supplied by NetSonar, and cycle through the Security Wheel by going through all these steps continuously.
