Abstract: The present disclosure relates to methods and apparatus for flexible, security context management during AMF changes. One aspect of the disclosure is a mechanism for achieving backward security during AMF changes. Instead of passing the current NAS key to the target AMF, the source AMF derives a new NAS key, provides the new NAS key to the target AMF, and sends a key change indication to the UE, either directly or through some other network node. The UE can then derive the new NAS key from the old NAS key. In some embodiments, the AMF may provide a key generation parameter to the UE to use in deriving the new NAS key. In other embodiments, the target AMF may change one or more security algorithms.

Abstract: The present disclosure describes techniques that allow for a client-side application, located on a first client device, to generate a random encryption key and encrypt locally-stored application data with the random encryption key. The random encryption key is used in lieu of a password-derived encryption key. In order to ensure that the client-device application is unable to decrypt the locally-stored encrypted application data prior to authenticating with an external authentication source (i.e., SSO, IdP), the random encryption key is encrypted with a key-encrypting key derived using a pseudorandom function (PRF). By using a PRF, the first device is able to authenticate to the first server and derive a secure key as part of the authentication process. Accordingly, the present disclosure describes techniques for securing data on a client device when credentials are managed by an external authentication system.

Abstract: An analyzer module forms a hypothesis on what are a possible set of cyber threats that could include the identified abnormal behavior and/or suspicious activity with AI models trained with machine learning on possible cyber threats. The Analyzer analyzes a collection of system data, including metric data, to support or refute each of the possible cyber threat hypotheses that could include the identified abnormal behavior and/or suspicious activity data with the AI models. A formatting and ranking module outputs supported possible cyber threat hypotheses into a formalized report that is presented in 1) printable report, 2) presented digitally on a user interface, or 3) both.

Abstract: A method of granting or denying access to data is disclosed herein. A server requests behaviometric data from a device regarding a user thereof. If behaviometric data is provided, the server uses it to authenticate the user. If behaviometric data is not provided, the server requests device-identifying data from the device. If the device-identifying data matches data of a device from which a user previously consented to collection of behaviometric data, behaviometric data is collected. If not, a request for collection is made.

Abstract: A transparent proxy for malware detection includes a monitor module, a protocol determination module, a challenge generation module, a response determination module, and a data control module. The monitor module examines data originating from an application towards a remote server. The protocol determination module identifies the protocol type used for the data. The challenge generation module produces a challenge for the application based upon the protocol type, sends the challenge to the application, and maintains a state related to the data and the challenge. The response determination module makes a determination if an automatic non-interactive application response is received in response to the challenge from the application. The data control module allows the first data to continue to the remote server when the determination is valid. The data control module reports malware detection and blocks the data to continue to the remote server when the determination is invalid.

Abstract: Aspects of the disclosure relate to improving user responses to cyber security threats. A computing platform may generate a test communication to simulate a potential cyber threat activity. Then, the computing platform may send, via the communication interface, the test communication to a user device associated with a target user. Then, the computing platform may receive, via the communication interface and from the user device, a response to the test communication. Subsequently, the computing platform may determine, based on the response, a threat awareness level for the target user, where the threat awareness level is indicative of a susceptibility of the target user to the potential cyber threat activity. Then, the computing platform may send, to the target user and based on the threat awareness level, an alert notification to counter the cyber threat activity.

Abstract: Methods and systems are presented for detecting malicious webpages based on dynamically configuring a device to circumvent one or more evasion techniques implemented within the malicious webpages. When a known malicious webpage is obtained, programming code of the known malicious webpage is analyzed to determine one or more evasion techniques implemented within the known malicious webpage. The one or more evasion techniques may cause a webpage classification engine to falsely classify the known malicious webpage as a non-malicious webpage. A software update is generated based on one or more feature parameters extracted from the one or more evasion techniques. The software update is used to for modify the webpage classification engine such that the webpage classification engine would correctly classify the known malicious webpage.
