Honeytokens and detection

I've been playing with the concept of Honeytokens, thinking of ways that they could apply to intrusion detection. Based on recent events, had some ideas. There have been reports of databases broken into, with thousands of social security numbers or millions of credit cards stolen. One of the problems is in some of these cases, it was not known for days, weeks, or even months that the data had been compromised. I was thinking that Honeytokes could be used for detecting when such data was compromised/stolen. Inside each database Honeytoken numbers are inserted. These tokens are known to have no value, no one should be using them. Detection mechanisms such as IDS signatures are then created to look for and detect these tokens being access or used. If these tokens are seen, this means someone has captured the database, or looking where they shouldn't be. For example, create bogus social security numbers and store them in your SSN database. If the honeytoken SSN's hit your network, someone may have just grabbed your database. For a CC database, insert honeytoken CC's and monitor for those to hit your wire. Once again, if you see someone retrieving these numbers, someone is most likely being naughty. The advantage with this detection method is its both very simple and should dramatically reduce false positives. What would be even better is if the IRS or some credit card companies could post or distribute such honeytoken numbers, so we within the security community are certain we are not implanting valid numbers. Either way, a thought to consider :) -- Lance Spitzner http://www.tracking-hackers.com
