Interfering SSIDs: Devices in ad-hoc mode can connect to a client AP and create a gateway for wireless hackers.

An AP spoof means that someone is deliberately impersonating your network and should be treated with the highest level of severity. Denial of Service DoS attacks are attempts to prevent clients from associating to the legitimate AP by sending an excessive number of broadcast messages to clients. DoS attacks could be from malicious clients, APs, or even another WIPS system in the area that considers the corporate network a threat and is attempting to remediate. Clients or APs that are sending an excessive number of packets to your AP. Packets are monitored and classified based on multiple categories including beacon, authentication and association frames.

An excessive number of any category of packets seen within a short time interval will be marked in Air Marshal as a packet flood. Access points feature the ability to contain rogue access points that can put your network at risk. This Knowledge Base article covers the following:.

Rogue Classification

When a rogue access point is contained, clients will be unable to connect to the rogue AP. Additionally, any currently associated clients will lose their connection to the rogue AP. The deauthentication packets force any clients that are connected to the rogue access point to disconnect. If a client attempts to connect to the rogue network, they will be immediately forced off by the Air Marshal. Dual-radio Meraki APs will run wireless scans opportunistically while also serving clients; this means they will scan the channel on which they are serving clients.

Dual-radio APs can be set into a dedicated Air Marshal mode where it will scan using both the 2. These APs do not require any dedicated Air Marshal configuration and will scan and remediate against threats in real-time.

Wildcard MAC address filtering can it be done?

For dual-radio Meraki access points: This Air Marshal AP will now be a dedicated sensor performing scans of the surrounding environments for threats, the results of which will be displayed on the WIPS page in real-time. A note on hybrid vs. APs with two radios running in client-serving mode will only scan the airspace opportunistically; this means they will scan the client-serving channel in real-time, and will scan across all channels either once a day or when no clients are being served. Most WLAN vendors recommend having dedicated scanning sensors with no clients being served in security conscious environments, to ensure real-time security alerting and protection.

Administrators may specify whether or not they wish for clients to be able to connect to rogue SSIDs. In some environments, this provides the necessary level of flexibility for proper workplace operations. This provides greatest level of security for the wireless network. Email and syslog alerts will also be generated if SSIDs matching the rules in the blacklist table are seen.

Lastly, administrators may configures rules to alert when SSIDs matching a rule are seen. Follow the steps below to manually apply a security policy to an SSID. Select edit and specify if you'd like to whitelist, contain, alert, or uncontain, as shown in Figure F. Upon evaluating the threat, you may wish to either blacklist or whitelist the SSID. This is a rogue wireless network that your Cisco Meraki AP is currently containing. Whenever a client attempts to connect to the rogue wireless network, they will be forced off via the deauthentication process described earlier.

This is a rogue wireless network that can not be completely contained because some of the rogue APs may be on a different channel. This can occur when a non-Air Marshal AP notices the rogue on a different channel during a channel scan. The AP can not fully contain the rogue wireless network because of the channel difference.

Deploying more APs with dedicated third Air Marshal scanning radios can help mitigate these issues. Whitelisted networks will not be contained in any way. This is a wireless network that was noticed during a scan, but has not been determined to be a threat to your network. When a wireless access point of any brand generates a beacon packet, it uses a BSSID, which is virtual physical address.

These can usually be ignored during common network operation, and are unlikely to result in noticeable RF interference. The criteria for a match are as follows:. This comparison is done with an Xor of the MAC address in binary notation. This example was detected by Air Marshal:. When the MAC addresses are written out in binary, you can see that very few of the bits are different. When performing an Xor, you see that only 3 significant bits in the calculation are different between the two MAC addresses. With the ability to locate Rogue SSIDs, administrators are better equipped to prevent unauthorized access points from operating on their local network.

After detection, an administrator is able to take action, either containing the SSID using Air Marshal, or using the gathered information to find the offending device and remove it from the network. Air Marshal is a WIPS platform which comes equipped with security alerting and threat remediation mechanisms. This includes the following:.

Air Marshal does this by generating a large number of Sampling of sites is not allowed. A WIPS is recommended for large organizations since it is not possible to manually scan or conduct a walk-around wireless security audit of all sites on a quarterly basis. Prepare an incident response plan to monitor and respond to alerts from the WIPS. Enable automatic containment mechanism on WIPS to block rogues and unauthorized wireless connections.

An example of a complete security methodology is as follows:. An Air Marshal AP has a wider effective radius than a regular AP, as it can detect and contain rogues at a lower bitrate than what is required for sustained client connectivity.

The coverage radius of an Air Marshal AP for sensing and remediating against rogue access points is approximately twice as large as the coverage area for serving clients; therefore, the total coverage area for WIPS scanning is approximately 4 times as large as the area for serving clients. A best-in-class WIPS platform should be capable of delivering intuitive reporting and monitoring, along with a robust suite of tools allowing for automatic alerts and security enforncement.
