Event-triggered reauthentication of at-risk and compromised systems and accounts
A system and method that detects and mitigates zero-day exploits and other vulnerabilities by analyzing event logs and external databases, forcing reauthentication of at-risk and comprised systems and accounts during an identified threat or potential security risk.
1. A system for event-triggered reauthentication, comprising:
a first computing system comprising a memory and a processor connected to a computer network
wherein the first computing system is configured to:
receive a plurality of system logs from a second computing system connected to the computer network;
generate a baseline usage profile of the second computing system based on the received system logs, wherein the baseline usage profile is updated based on receipt of the received system logs from the second computing system;
receive a request from the second computing system to authenticate access to a service;
in response to the received request to authenticate access to the service, determine, based on the baseline usage profile of the second computing system, whether to require additional verification from the second computing system;
retrieve a dataset of known exploit information from a plurality of databases;
identify a cybersecurity threat related to the second computing system by comparing the baseline usage profile and events within the system logs against the dataset of known exploit information; and
in response to identifying the cybersecurity threat, trigger a forced reauthentication to allow the second computing system to maintain continued access to the service.
2. The system of claim 1 , wherein the forced reauthentication is triggered regardless of the determination whether to require additional verification from the second computing system.
3. The system of claim 1 , wherein the first computing system is implemented as a cloud-based service that monitors a remote computing device using a software agent and enforces authentication over the computer network.
4. The system of claim 1 , wherein the first computing system is implemented as a server on an enterprise network that monitors all computing devices on the enterprise network and enforces authentication over the computer network.
5. The system of claim 1 , wherein the service is an operating system service.
6. The system of claim 1 , wherein the service is a cloud-based service.
7. The system of claim 1 , wherein the forced reauthentication uses two-factor authentication.
8. The system of claim 1 , wherein the forced reauthentication is selected from a plurality of verification methods, wherein:
each verification method is associated with a number of points;
the successful completion of a verification method awards the number of points associated with that verification method;
the total number of points available for successful completion of the plurality of verification methods is equal to or greater than the verification score; and
at least one of the verification methods is a non-automated verification method requiring a manual input.
9. A method for event-triggered reauthentication, comprising the steps of:
receiving a plurality of system logs from a computing system connected to a computer network;
generating a baseline usage profile of the computing system based on the received system logs, wherein the baseline usage profile is updated based on receipt of the received system logs from the computing system;
receiving a request from the computing system to authenticate access to a service;
in response to the received request to authenticate access to the service, determining, based on the baseline usage profile of the computing system, whether to require additional verification from the computing system;
retrieving a dataset of known exploit information from a plurality of databases;
identifying a cybersecurity threat related to the computing system by comparing the baseline usage profile and events within the system logs against the dataset of known exploit information; and
in response to identifying the cybersecurity threat, triggering a forced reauthentication to allow the computing system to maintain continued access to the service.
10. The method of claim 9 , wherein the forced reauthentication is triggered regardless of the determination whether to require additional verification from the second computing system.
11. The method of claim 9 , wherein the method is implemented as a cloud-based service that monitors a remote computing device using a software agent and enforces authentication over the computer network.
12. The method of claim 9 , wherein the method is implemented on a server on an enterprise network that monitors all computing devices on the enterprise network and enforces authentication over the computer network.
13. The method of claim 9 , wherein the service is an operating system service.
14. The method of claim 9 , wherein the service is a cloud-based service.
15. The method of claim 9 , wherein the forced reauthentication uses two-factor authentication.
16. The method of claim 9 , wherein the forced reauthentication is selected from a plurality of verification methods, wherein:
each verification method is associated with a number of points;
the successful completion of a verification method awards the number of points associated with that verification method;
the total number of points available for successful completion of the plurality of verification methods is equal to or greater than the verification score; and
at least one of the verification methods is a non-automated verification method requiring a manual input.
