    摘要： A method involves performing a mathematical estimation operation identifying a risk score threshold. The operation identifies the risk score threshold as a point on a curve rather than a value of a particular risk score. Such a curve approximates the distribution of risk score values output over a time interval and represents a function embodied by a plot of risk score percentile vs. risk score value. The risk engine, rather than selecting a particular risk score, selects a curve from a family of curves that is known to accurately represent such risk score distributions. For example, the risk engine may choose the curve that provides the best fit to the previous week's risk scores over the family of curves. The risk engine identifies the risk score threshold by finding a risk score value such that the function evaluated at that risk score value produces a specified risk score percentile.

    摘要： A technique shares smart television data among subscribing organizations to provide security. The technique involves collecting, by an electronic server apparatus, data elements from multiple smart television devices. The technique further involves performing, by the electronic server apparatus, a set of risk analysis operations to generate risk scores corresponding to the multiple smart television devices. Each risk score (e.g., a numerical value) indicates an amount of risk (e.g., a probability) that a respective smart television device is malicious. The technique further involves providing, by the electronic server apparatus, an ordered list of the multiple smart television devices, the ordered list ranking the multiple television devices based on the risk scores. Information from the ordered list is well suited for use by an anti-fraud service in which subscriber organizations are informed of the information and use the information to identify and stop fraudulent activity in the future.

    摘要： Techniques of risk-based authentication involve adjusting a risk engine used by a recipient entity based on feedback acquired from multiple entities. Along these lines, both a recipient risk engine and one or more donor risk engines perform risk-based authentication for which respective feedback is generated. The feedback indicates whether certain transaction requests predicted to be fraudulent are confirmed to be fraudulent. The recipient risk engine is then adjusted based on the feedback created for itself, the feedback created for any of the donor risk engines, or some combination thereof.

    摘要： An improved technique involves inputting data in postings from social media or news websites into a risk engine. A posting extraction device continually observes postings aggregated in social media and news websites, such as Twitter, Facebook, CNN, and the like. The posting extraction device parses postings that contain specified keywords such as “credit card,” “account number,” and the like. The posting extraction device also parses these postings for metadata such as user identifiers, times, and locations. The posting extraction device then stores the parsed information in a transaction database that is accessed by an adaptive authentication engine for risk score assignment.

    摘要： Techniques of operating intrusion detection systems provide a recommendation of an intrusion detection rule to an administrator of an intrusion detection system based on the experience of another administrator that has used the rule in another intrusion detection system. For example, suppose that electronic circuitry receives a numerical rating from a first intrusion detection system that indicates whether an intrusion detection rule was effective in identifying malicious activity when used in the first intrusion detection system. Based on the received rating and attributes of the first intrusion detection system, the electronic circuitry generates a predicted numerical rating that indicates whether the intrusion detection rule is likely to be effective in identifying malicious communications when used in a second intrusion detection system. If the predicted numerical rating is sufficiently high, then the electronic circuitry transmits a message to the second intrusion detection system recommending the intrusion detection rule for use in the second intrusion detection system.
