Honey pot and Evil Twin. Good stuff Tor,
But again they seem to mention those 2 in the same sentences. In your article they mention honeypots but sometimes it is written honey pot, so perhaps you didn´t search for that one. here is something from your link: "Cisco couples these advanced detection and classification techniques with an extensive attack, vulnerability, and performance detection library. Examples of event classes detected include: rogue access points/clients, ad hoc connections, hacker access points such as honeypots and evil twins, network reconnaissance, authentication and encryption cracking, man-in-the-middle attacks such as address/identity spoofing and replay attacks, protocol attacks, denial-of-service (DoS) attacks, over-the-air and network security vulnerabilities, and performance issues such as co-channel interference and coverage holes." Does someone care to explain the difference ? I am begining to think that there is no major difference between the two. But the conversation is good. Makes you remember this forever :) So I stick with using both in OEQ format. That cant hurt. regards. Kristjan From: Tor A. L.

OEQ Answers (second) I will go for Evil Twin as Kelvin advocates for. Rouges offering same SSID is performing an "Impersonation and Spoofing Attack" and if we take a look on Cisco WIPS "Impersonation and Spofing Detection" is described as "Analyzes traffic behavior, performs pattern matching and authentication methods to detect tools and techniques such as MAC/IP spoofing, fake access points, evil-twin access points, Dynamic Host Configuration Protocol (DHCP) spoiling, and other methods, providing an alert of potential data theft or unauthorized network access". Herein is, in fact, mentioned the Evil Twin whereas there is nothing about "Honeypot AP". http://www.cisco.com/en/US/prod/collateral/wireless/ps9733/ps9817/data_sheet_c78-501388.html As a side note I would like to mention that, in the CCNP Wireless Course IAUWS, the definition of Evil Twin actually is stated as Rouge advertising "our" SSID. Tor On 17/10/2010, at 17.19, Kelvin Dam wrote: Im may very well be way off here, but Im not convinced that the definition of "honeypot" you posted is correct. I believe that a Evil Twin is an AccessPoint, broadcasting the same SSID as a corporation for instance, trying to lure users to use it. A HoneyPot is more or less the same, but doesnt have to be the same SSID, and also used by admins to lure attackers into a confined subnet to be monitored. Im basing my assumptions on these : Evil Twin The attacker uses a bogus base station<http://en.wikipedia.org/wiki/Base_station> that someone connects to using Wi-Fi<http://en.wikipedia.org/wiki/Wi-Fi> wireless technology. By imitating the name of another, legitimate wireless provider, they can fool people into trusting the internet services that they are providing. When the users log into bank or e-mail<http://en.wikipedia.org/wiki/E-mail> accounts, the phishers have access to the entire transaction, since it is sent through their equipment. Unwitting web<http://en.wikipedia.org/wiki/World_Wide_Web> users are invited to log into the attacker's server<http://en.wikipedia.org/wiki/Server_(computing)> with bogus login prompts, tempting them to give away sensitive information such as usernames<http://en.wikipedia.org/wiki/Username> and passwords<http://en.wikipedia.org/wiki/Password>. Often users are unaware they have been duped until well after the incident has occurred. Users think they have logged on to a wireless hotspot connection when in fact they have been tricked into connecting to the attacker's base station. The hacker jams the connection to the legitimate base station by sending a stronger signal within proximity to the wireless client - thereby turning itself into an 'evil twin.' A rogue Wi-Fi connection can be set up on a laptop with a bit of simple programming and wireless card that acts as an access point. The access points are hard to trace, since they can suddenly be shut off, and are easy to build. A hacker can make their own wireless networks that appear to be legitimate by simply giving their access point a similar name to the Wi-Fi network on the premises. Since the hacker may be physically closer to the victim than the real access point, their signal will be stronger, potentially drawing more victims. The hacker's computer can be configured to pass the person through to the legitimate access point while monitoring the traffic of the victim, or it can simply say the system is temporarily unavailable after obtaining a user id and password.[3]<http://en.wikipedia.org/wiki/Evil_twin_(wireless_networks)#cite_note-2> HoneyPots A honeypot is valuable as a surveillance and early-warning tool. While it is often a computer, a honeypot can take other forms, such as files or data records, or even unused IP address<http://en.wikipedia.org/wiki/IP_address> space. A honeypot that masquerades as an open proxy<http://en.wikipedia.org/wiki/Open_proxy> to monitor and record those using the system is a sugarcane. Honeypots should have no production value, and hence should not see any legitimate traffic or activity. Whatever they capture is therefore malicious or unauthorized. One practical application of this is a honeypot that thwarts spam<http://en.wikipedia.org/wiki/Spam_(electronic)> by masquerading as a type of system abused by spammers. These honeypots categorize trapped material 100% accurately: it is all illicit. Honeypots can carry risks to a network, and must be handled with care. If they are not properly walled off, an attacker can use them to break into a system. Victim hosts<http://en.wikipedia.org/wiki/Host_(network)> are an active network counter-intrusion tool. These computers run special software, designed to appear to an intruder as being important and worth looking into. In reality, these programs are dummies, and their patterns are constructed specifically to foster interest in attackers. The software installed on, and run by, victim hosts is dual purpose. First, these dummy programs keep a network intruder occupied looking for valuable information where none exists, effectively convincing him or her to isolate themselves in what is truly an unimportant part of the network. This decoy strategy is designed to keep an intruder from getting bored and heading into truly security-critical systems. The second part of the victim host strategy is intelligence gathering. Once an intruder has broken into the victim host, the machine or a network administrator can examine the intrusion methods used by the intruder. This intelligence can be used to build specific countermeasures to intrusion techniques, making truly important systems on the network less vulnerable to intrusion. Any takers on this? :) Kelvin 2010/10/15 Kristján Ólafur Eðvarðsson <[email protected]<mailto:[email protected]>> Hi Kelvin, That OEQ was rather good. I gave it some thought and scrolled through the help of my WCS server. Which in fact is very good and explains a lot of things. It is a rouge AP so It cant be a friendly based on that fact. Malicious is the same thing basically as a rouge. So they are probably looking for a classification of that rouge. I first read through the classifications of rouges and didn't see a clear answer to that questions but for everyone I like to share this info. "Rogue Access Point Classification Types Rogue access points classification types include: Malicious-Detected but untrusted or unknown access points with a malicious intent within the system. They also refer to access points that fit the user-defined malicious rules or have been manually moved from the friendly access point classification. See "Malicious Rogue APs" for more information. Friendly-Known, acknowledged, or trusted access points. They also refer to access points that fit the user-defined friendly rogue access point rules. Friendly rogue access points cannot be contained. See "Friendly Rogue APs" for more information. For more information on configuring friendly access point rules, see "Configuring Friendly AP Controller Templates". Unclassified-Rogue access point that are not classified as either malicious or friendly. These access points can be contained and can be moved manually to the friendly rogue access point list. See for more information. See "Unclassified Rogue APs" for more information." However when I was reading this I just remembered that I have sometimes got this warning in WCS in real setups. "With Honey pot AP detected" And this seems to best answer to this question. Do you guys agree ? "Honey Pot AP Detected Alarm Description and Possible Causes The addition of WLANs in the corporate environment introduces a whole new class of threats for network security. RF signals that penetrate walls and extend beyond intended boundaries can expose the network to unauthorized users. A rogue access point can put the entire corporate network at risk for outside penetration and attack. Not to understate the threat of the rogue access point, there are many other wireless security risks and intrusions such as mis-configured access points, unconfigured access points, and DoS (denial-of-service) attacks. One of the most effective attacks facing enterprise networks implementing wireless is the use of a "honey pot" access point. An intruder uses tools such as NetStumbler, Wellenreiter, and MiniStumbler to discover the SSID of the corporate access point. Then the intruder sets up an access point outside the building premises or, if possible, within the premises and broadcasts the discovered corporate SSID. An unsuspecting client then connects to this "honey pot" access point with a higher signal strength. When associated, the intruder performs attacks against the client station because traffic is diverted through the "honey pot" access point. wIPS Solution When a "honey pot" access point is identified and reported by the Cisco Adaptive Wireless IPS, the WLAN administrator may use the integrated over-the-air physical location capabilities, or trace device on the wired network using rogue location discovery protocol (RLDP) or switchport tracing to find the rogue device.
