User authenticationblocks out unauthorized access to the wired and wireless resources. Trafficencryption goes hand-in-hand with user authentication during which theencryption secrets are exchanged between AP and authorized users. Trafficencryption prevents intruders from eavesdropping into the wireless traffic.Cisco wIPS validates your WLAN security deployment by monitoring on theauthentication transactions and traffic encryption methods against thespecified security deployment policy, which Cisco wIPS learns from the policyconfiguration. For example, the Cisco wIPS generates the Device unprotected by PEAP alarm if the 802.1x EAPtype-PEAP is theenterprise standardized authentication protocol. Common security violations inthis category (authentication and encryption) include mis-configurations,out-of-date software/firmware, and suboptimal choice of corporate securitypolicy. Cisco wIPS alerts the administrator on these issues and providescounter measures.
Statistics show thatmore than 50 percent of WLANs do not implement any encryption method. Even withthe potential vulnerability of static WEP, it is still safer than no encryptionat all. If you decide to use static WEP, there are ways to keep it as secure asWEP can provide. Cisco wIPS assists you in accomplishing this goal bymonitoring on static WEP usage and identifying security holes such as crackableWEP key usage, shared-key authentication, and detecting devices that do not useWEP.
Cisco wIPS alerts theadministrator on any AP operating without any WLAN layer 2 data encryptionmechanisms such as WEP, TKIP, or AES. VPN technologiesat layer three and above are the most commonly used alternative to the WLANlayer 2 data encryption mechanisms . If neither of the encryption mechanismsare used, data exchanged between an AP and its client stations is subject toeavesdropping by intruders. For an AP that is operating without any sort ofencryption mechanism, there can be unauthorized clients without encryption keysthat can associate with the AP and obtain access to the enterprise wirednetwork. This puts at risk not only the user data privacy but also exposes thecorporate wired network access. This alarm may be turned off for the enterpriseguest WLAN network or for hot spot deployments where encryption is notrequired. You can turn on the Publicly Secure Packet Forwarding (PSPF-term generally usedby Cisco Aironet access points. Other vendors may call this differently) alarmto protect your wireless network operating without any encryption. PSPF is afeature implemented on the WLAN Access Points to block wireless clients fromcommunicating with other wireless clients. PSPF protects public networks byprohibiting wireless traffic between wireless clients.

VPN technologies at layerthree and above are the most commonly used alternative to the WLAN layer 2 dataencryption mechanisms . If neither of the encryption mechanism is used, dataexchanged between an AP and its client stations is subject to eavesdropping byintruders. Clients with WEP disabled put at risk their file system that maycontain confidential corporate information from wireless intruders. Theseclients can then act as an entry point for the intruders into the corporatenetwork. This alarm may be turned off for the enterprise guest WLAN network orfor hot spot deployments where encryption is generally not required.

WLAN devices usingstatic WEP key for encryption are vulnerable to WEP key cracking attack. TheWEP secret key that has been cracked by any intruder results in no encryptionprotection, thus leading to compromised data privacy. The WEP key which is in64-bit or 128-bit (few vendors also offer 152-bit encryption) consists of thesecret key specified by the user concatenated with the 24-bit IV(Initialization Vector). The IV that is determined by the transmitting stationcan be reused frequently or in consecutive frames, thus increasing thepossibility of the secret key to be recovered by wireless intruders. Byexcluding certain IV values that would create \"weak keys,\" the weakness of WEPis avoided.
Cisco wIPS alerts onweak WEP implementations and recommends a device firmware upgrade if availablefrom the device vendor to correct the IV usage problem. Ideally, enterpriseWLAN networks can protect against WEP vulnerability by using the Temporal KeyIntegrity Protocol (TKIP) encryption mechanism, which is supported by mostenterprise level wireless equipment. TKIP enabled devices are not subject toany WEP key attacks.
802.11 OpenAuthentication (as opposed to Shared-key authentication) is widely used todayin conjunction with a higher level authentication protocol such as 802.1x tosecure a WLAN. In some deployments, Shared-key Authentication is used insteadof Open Authentication where a static WEP key is used to challenge clientstations attempting to associate with the AP. Open Authentication on the otherhand accepts associations from any client and there is no verification of theidentity of the client. Shared-key authentication appears to be more secure buthas been proven to be vulnerable to WEP key cracking by wireless intrudersbecause the challenge text and response are both clear and unencrypted.
Cisco wIPS detectsthe use of Shared Key Authentication and advises alternatives. Many enterprisestoday deploy 802.11 WLANs using Open Authentication instead of Shared KeyAuthentication with a higher level authentication mechanism provided by 802.1xand EAP methods such as LEAP, PEAP and TLS .

Ideally, enterpriseWLAN networks can protect against WEP vulnerability by using the Temporal KeyIntegrity Protocol (TKIP) encryption mechanism, which is now supported by mostenterprise level wireless equipment. TKIP enabled devices are not subject toany such WEP key attacks.
802.1x has aframework allowing a system to use per-session encryption keys to defendagainst the weakness inherited from the global static WEP key mechanism. 802.1xprovide per-session encryption keys and also facilitates the session keyrotation mechanism there by ensuring that the encryption keys are updatedperiodically. This enhances security by eliminating the use of staticencryption keys and preventing attacks that require the collection of largeamounts of data encrypted with a single static key. For multicast and broadcastpackets, where there are multiple recipients, per-session encryption key cannotbe applied. In order to secure multicast and broadcast communication, a sharedencryption key and re-key mechanism has to be implemented. It has been foundthat very few wireless devices implement the multicast and broadcast encryptionkey mechanism correctly. In reality, multicast and broadcast packets are notencrypted. To make matters more complicated, enterprise grade APs with multipleSSIDs are frequently deployed with 802.1x security for one SSID (corporateWLAN) and no encryption for another SSID (guest WLAN). This deployment scenariois usually coupled with the VLAN configuration so that client devices using theguest SSID can only access the Internet but not the corporate wired network. AnAP supporting multiple SSIDs transmits broadcast and multicast frames thusmaking the encryption option selection (802.1x or no encryption) , animplementation challenge.
A cracked WEP secretkey results in no encryption protection so, data privacy will have to becompromised. Dynamic encryption key or key rotation mechanisms such as TemporalKey Integrity Protocol (TKIP) resolves such vulnerabilities by periodicallychanging the encryption key even within a single session. Managing key rotationfor multicast and broadcast traffic is challenging technically because multipledevices have to update to the new key synchronously. Vendors' implementationsof multicast or broadcast key rotation varies from null to complete. When themulticast and broadcast key is not rotated or rotated infrequently, it is asweak as static WEP, which is subject to key recovery attacks. By continuouslymonitoring on the WLAN 802.1x authentication and encryption transactions, CiscowIPS can detect an AP configured without encryption key rotation or configuredwith a long key rotation timeout. It is important for WLAN 802.1xconfigurations to include a reasonable encryption rekey timeout . A staledencryption key makes your encryption static and as vulnerable as static WEP keyencryption. A rekey mechanism should be applied to unicast, multicast, andbroadcast data streams. TKIP enabled devices implement a WEP key hashingalgorithm and typically rotate keys on their unicast data streams but notalways on the multicast or broadcast data streams. 153554b96e
