Latest Patents

Numainville's latest patents focus on advanced methods for identity attack detection and blocking. The first patent, titled "Identity attack detection and blocking," describes embodiments that detect identity attacks by comparing the usage of compromised passphrases or weak credentials in failed sign-in attempts. By establishing a restriction threshold for weak credential failed sign-ins, the system can identify potential identity attacks, such as password spray attacks, more effectively than traditional methods. This innovative approach allows for quicker detection and the implementation of defenses, such as locking accounts or blocking IP addresses.

The second patent, "Identity spray attack detection with adaptive classification," utilizes a machine learning model to classify account access attempts as authorized or unauthorized. This model employs various features, including user agent reputation data and IP address reputation data, to enhance detection capabilities. The adaptability of the model allows it to retrain with updated data, making it more effective over time compared to rigid detection methods.
