I should note that there is no location information embedded into these packets.

Most Android and iPhone devices send out this request every 40 to 60 seconds, which makes using these to track the movement of people specifically useful. This packet is sent out by smartphones, laptops, and other devices that are not currently connected to a WiFi network. The most interesting WiFi packet to us in this case is the Probe Request Frame. If you do this, you can see that in an area with moderate WiFi usage or number of access points, there are dozens of WiFi packets visible to you every second. Something like this: $ iwconfig wlan0 mode monitorĪfter this, I used the command line version of wireshark, tshark, to capture WiFi packets and output them.
I have a desktop linux machine that is very close to the outside wall, so I started by putting my WiFi chip into monitor mode. If shopping malls can do it, so can anyone. My immediate next thought was capturing people's WiFi MAC addresses. What else could we do to link the person to the crime? But beyond that I started to think how easy it migtht be to refute video evidence, especially at night with a low quality camera. The obvious first thought was to set up a camera. After the third time I thought it might be worth investing some energy into catching them. MAC addresses are unique per device so they will give you a reliable audit trail as to what is happening on your network.In the past month or two, someone has spray painted the brick wall outside my apartment building with graffiti three separate times, after being painted over each time. Most networks use DHCP servers so you cannot rely on tracking activity based on IP addresses only.
The MAC address variable is an important one when it comes to tracking devices on your network. They could also drill down to URI level when they need to investigate an incident. WIth a solution including an HTTP decoder, they can capture and analyze wire data off a SPAN or mirror port to track proxy or non-proxy traffic by IP or MAC address. And, because most of the users are just passing through-thousands of wireless users every hour-the only way to uniquely identify each user or device is by MAC address. Their basic requirement and use case is tracking web activity, keeping a historical record of it for a period of one year. Out-of-band network forensics for troubleshooting or identifying odd network traffic.Ĭonsider this example: The end user is a large airport in Europe.Employees streaming movies is a frequent cause. Find out why your internet connection is slow.Finding the source of Bittorrent use would be a common requirement on open networks. Maintain logs so that you can respond to third-party requests.Track it down to specific users, IP addresses, or MAC addresses Root out the source of ransomware and other security threats.You only see the big picture when you have all of these variables in front of you. Relevant information includes things like MAC address, source IP, destination IP, time, website, URI, and username. The trick is to pull the relevant information and discard the rest so you don’t end up storing massive packet captures. You can enable packet capturing with SPAN/mirror ports, packet brokers, TAPs, or by using promiscuous mode on virtual platforms. One of the best data sources for web tracking is packet capture. The main reason for this is that it does not look at HTTP headers where a lot of the important information is stored. However, as with server logs, NetFlow isn’t a web usage tracker. The idea is that you get flow records from the edge of your network so you can see what IP address is connecting to what. Some vendors are pitching flow type tools to address the problem. They are meant to provide server administrators with data about the behavior of the server, not what users are doing on the internet. Server log files do not always have the answer, either. These systems were designed to block or control access and reporting was just added on at a later date. While some firewalls and proxy servers include reporting capabilities, most are not up to the job. As internet usage constantly grows, malicious, phishing, scamming, and fraudulent sites are also evolving.

One of the main drivers for this is the need to keep the network secure. For many years, IT managers have tried to get some sort of visibility at the network edge so that they can see what is happening. Last updated at Fri, 15:52:44 GMT Associating internet activity with MAC addresses
