Probe-based risk analysis for multi-factor authentication
A system for probe-based risk analysis for multi-factor authentication having a multi-dimensional time series data server configured to monitor and record a network's traffic data and to serve the traffic data to other modules and a directed computational graph module configured to probe connection destinations for a response, analyze any received responses, and determine a verification score needed before granting access based at least in part on the analysis of the received responses. A plurality of verification methods build up a user's verification score to required level to gain access.
1. A system for probe-based risk analysis for multi-factor authentication, comprising:
a computing system comprising a memory, a processor, and a network interface; and
a directed computational graph subsystem comprising a plurality of programming instructions that, when operating on the processor, cause the computing system to:
receive network traffic data; and
upon identifying, from the received network traffic data, a connection attempt from a user device to an intended destination with unknown risk potential:
transmit a plurality of probe packets to the intended destination of the connection attempt;
receive a plurality of response packets from the intended destination of the connection attempt; and
determine a required verification score for granting access from the user device to the intended destination based at least in part on analysis of the received response packets and the plurality of probe packets that were transmitted.
2. The system of claim 1 , wherein a plurality of verification methods is used to build up a user's verification score to the required verification score in order for the user to gain access to the intended address.
3. The system of claim 1 , wherein the verification score is based at least in part on stored knowledge pertaining to the user.
4. The system of claim 3 , wherein the stored knowledge pertaining to the user comprises at least knowledge of user access privileges to resources on the local network.
5. The system of claim 2 , wherein at least a portion of the verification methods verifies visual media pertaining to the user.
6. The system of claim 2 , wherein at least a portion of the verification methods checks and verifies biometric features of the user.
7. The system of claim 2 , wherein at least a portion of the verification methods used are based on information obtained from untrusted parties.
8. The system of claim 2 , wherein at least a portion of the verification methods used are based on information pertaining to the user's device.
9. A method for probe-based risk analysis for multi-factor authentication, comprising the steps of:
using a directed computation graph subsystem of computing system comprising a memory, a processor, and a network interface:
receiving network traffic data; and
upon identifying, from the received network traffic data, a connection attempt from a user device to an intended destination with unknown risk potential:
transmitting a plurality of probe packets to the intended destination of the connection attempt;
receiving a plurality of response packets from the intended destination of the connection attempt; and
determining a required verification score for granting access from the user device to the intended destination based at least in part on analysis of the received response packets and the plurality of probe packets that were transmitted.
10. The method of claim 9 , further comprising the step of requiring the user to use a plurality of verification methods to earn enough verification score in order to gain access to the intended destination.
11. The method of claim 9 , wherein the verification score is based at least in part on stored knowledge pertaining to the user.
12. The method of claim 11 , wherein the stored knowledge of the user comprises at least knowledge of user access privileges to resources on the local network.
13. The method of claim 10 , wherein at least a portion of the verification methods verifies visual media pertaining to the user.
14. The method of claim 10 , wherein at least a portion of the verification methods checks and verifies biometric features of the user.
15. The method of claim 10 , wherein at least a portion of the verification methods used are based on information obtained from untrusted parties.
16. The method of claim 10 , wherein at least a portion of the verification methods used are based on information pertaining to the user's device.
