This document provides information on Rogue Detection and Mitigation on Cisco Wireless Networks.for Mac. To manage the tool, it creates a management access point.Cisco Unified Network Architecture provides methods for rogue detection that enable a complete rogue identification and containment solution without the need for expensive and hard-to-justify overlay networks and tools. Therefore, an employee who brings his or her own Access Point (Cisco or Non Cisco) into a well-secured wireless or wired infrastructure and allows unauthorized users access to this otherwise secured network, can easily compromise a secure network.Rogue detection allows the network administrator to monitor and eliminate this security concern. Less thought is put into port security on wired networks, and wireless networks are an easy extension to wired networks. However, an unauthorized wireless network presents an additional layer of security concern. Manage network settingsWireless networks extend wired networks and increase worker productivity and access to information.However, there are certain scenarios in which rogue detection is not needed, for example, in Office Extend Access Point (OEAP) deployment, citywide, and outdoors. A rogue becomes dangerous in these scenarios:When setup to use the same Service Set Identifier (SSID) as your network (honeypot).When it is detected on the wired network.Setup by an outsider, most times, with malicious intent.The best practice is to use rogue detection to minimize security risks, for example, in a corporate environment. Rogue OverviewAny device that shares your spectrum and is not managed by you can be considered a rogue. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.
![]() Name Of Program That Manages Wireless Network Download The FreeThis includes rogue Access Points, wireless router, rogue clients, and rogue ad-hoc networks. Rogue classification rules also assist in the filtration of rogues into specific categories based on their characteristics.Mitigation - Switch port shutting, rogue location, and rogue containment are used in to track down its physical location and to nullify the threat of the rogue device.A rogue is essentially any device that shares your spectrum, but is not in your control. Finally, it is critical to evaluate (or avoid altogether) rogue auto-containment, as there are potential legal issues and liabilities if left to operate automatically.There are three main phases of rogue device management in the Cisco Unified Wireless Network (UWN) solution:Detection - Radio Resource Management (RRM) scanning is used to detect the presence of rogue devices.Classification - Rogue Location Discovery Protocol (RLDP), Rogue Detectors (Wave 1 APs only) and switch port tracing are used to identify if the rogue device is connected to the wired network. ![]() This limits the performance impact to a maximum of 1.5% and intelligence is built into the algorithm to suspend scanning when high-priority QoS frames, such as voice, need to be delivered.This graphic is a depiction of the off-channel scanning algorithm for a local mode AP in the 2.4GHz frequency band. Both the list of channels and scan interval can be adjusted in the RRM configuration. For other regulatory domains, such as ETSI, the AP will be off channel for a slightly higher percentage of time.

Monitor mode APs are also far superior at the detection of rogue clients as they have a more comprehensive view of the activity that occurs in each channel.This graphic is a depiction of the off-channel scanning algorithm for a monitor mode AP in the 2.4GHz frequency band. This allows a greater speed of detection and enables more time to be spent on each individual channel. Monitor Mode ScanningThis operation is performed by Monitor Mode and Adaptive wIPS monitor mode APs which utilizes 100% of the radio's time for scanning all channels in each respective frequency band. Each red square represents the time spent on the APs home channel, whereas each blue square represents time spent on adjacent channels for scanning purposes. When monitor mode APs are additionally configured with Adaptive wIPS, a broader range of over-the-air threats and attacks can be detected.Serves clients with time-slicing off-channel scanningIf probe response or beacons from a rogue device are heard by either local, flex-connect or monitor mode APs, then this information is communicated via CAPWAP to the Wireless LAN controller (WLC) for the process. A monitor mode AP can simultaneously be used for Adaptive wIPS, location (context-aware) services, and other monitor mode services.When monitor mode APs are deployed, the benefits are lower time-to-detection. A monitor mode AP spends all of its cycles on the scan of channels to look for rogues and over-the-air attacks. This becomes an exercise in probabilities. Consequently, rogue and attack detection times are longer (3 to 60 minutes) and a smaller range of over-the-air attacks can be detected than with a monitor mode AP.Furthermore, detection for bursty traffic, such as rogue clients, is much less deterministic because the AP has to be on the channel of the traffic at the same time the traffic is transmitted or received. As a result, it takes a local mode AP longer to cycle through all the channels, and it spends less time in the collection data on any particular channel so that client operations are not disrupted. Any detected rogue clients or APs are sent to the controller, which gathers this information:The rogue connected client(s) MAC addressThe Receiver Signal Strength Indicator (RSSI)Rogue SSID (if the rogue SSID is broadcasted)First and last time the rogue is reportedIn order to export rogue events to a third-party Network Management System (NMS) for archival, the WLC permits additional SNMP trap receivers to be added. Rogue DetailsA CAPWAP AP goes off-channel for 50ms in order to listen for rogue clients, monitor for noise, and channel interference. Rogue RecordsWhile the controller’s database of rogue devices contains only the current set of detected rogues, the PI also includes an event history and logs rogues that are no longer seen. These methods include mobility group updates, RF neighbor packets, and allowed list friendly APs via Prime Infrastructure (PI). After a user configurable timeout (1200 seconds default), a rogue in the _unclassified_category is aged out.Rogues in other states such as _Contained_and _Friendly_will persist so that the appropriate classification is applied to them if they reappear.There is a maximum database size for rogue records that is variable across controller platforms:3504 - Detection and containment of up to 600 Rogue APs and 1500 Rogue Clients Rogue Record TimeoutOnce a rogue AP has been added to the WLC's records, it will remain there until it is no longer seen. One caveat with the export of events via SNMP is that if multiple controllers detect the same rogue, duplicate events are seen by the NMS as correlation is only done at PI. 8540 - Detection and containment of up to 24000 Rogue APs and 32000 Rogue ClientsA rogue detector AP aims to correlate rogue information heard over the air with ARP information obtained from the wired network.
