Detecting and mitigating forged authentication object attacks in multi-cloud environments
A system for detecting and mitigating forged authentication object attacks in federated environments is provided, comprising an event inspector to monitor logs and detect vulnerable events, an authentication object inspector configured to observe a new authentication object generated by an identity provider, and intercept the new authentication object; and a hashing engine configured to calculate a cryptographic hash for the new authentication object, and store the cryptographic hash for the new authentication object in the SAML response; wherein subsequent access requests accompanied by authentication objects are validated by comparing hashes for each authentication object to previous generated hashes.
1. A system for detecting and mitigating forged authentication object attacks in federated environments, comprising:
an authentication object inspector comprising a first plurality of programming instructions stored in a memory of, and operating on a processor of, a computing device, wherein the first plurality of programmable instructions, when operating on the processor, cause the computing device to:
receive an authentication object known to be generated by an identity provider;
calculate a cryptographic hash of the authentication object using a hashing engine;
store the cryptographic hash in the authentication object;
forward the authentication object to the service provider; and
where the hash of the authentication object does not exist in the authentication object received by the service provider, generate a notification that the authentication object may be forged; and
an event inspector comprising a second plurality of programming instructions stored in the memory of, and operating on the processor of, the computing device, wherein the third plurality of programmable instructions, when operating on the processor, cause the computing device to:
monitor a plurality of service provider logs for a successful login event or a certificate export event;
identify one or more entities associated with the successful login event or a certificate export event;
search a plurality of security event logs from the one or more associated entities for corresponding events to determine if the successful login event is legitimate; and
trigger the execution of one or more commands as dictated in a plurality of predefined rules upon detection of an illegitimate login event or a certificate export event.
2. The system of claim 1 , wherein, upon detection of an invalid authentication object, an administrative user is notified, and provided with access data associated with the invalid authentication object.
3. The system of claim 2 , wherein at least a portion of the access data comprises resources accessed by the owner of the invalid authentication object.
4. The system of claim 2 , wherein at least a portion of the access data comprises blast radius data associated with the owner of the invalid authentication object.
5. A method for detecting and mitigating forged authentication object attacks in federated environments, comprising the steps of:
receiving an authentication object known to be generated by an identity provider;
calculating a cryptographic hash of the authentication object using a hashing engine;
storing the cryptographic hashes in the authentication object;
forwarding the authentication object to the service provider
where the hash of the authentication object does not exist in the authentication object received by the service provider, generating a notification that the authentication object may be forged;
monitoring a plurality of service provider logs for a successful login event or a certificate export event;
identifying one or more entities associated with the successful login event or a certificate export event;
searching a plurality of security event logs from the one or more associated entities for corresponding events to determine if the successful login event is legitimate; and
triggering the execution of one or more commands as dictated in a plurality of predefined rules upon detection of an illegitimate login event or a certificate export event.
6. The method of claim 1 , wherein, upon detection of an invalid authentication object, an administrative user is notified, and provided with access data associated with the invalid authentication object.
7. The method of claim 6 , wherein at least a portion of the access data comprises resources accessed by the owner of the invalid authentication object.
8. The method of claim 6 , wherein at least a portion of the access data comprises blast radius data associated with the owner of the invalid authentication object.
