Abstract: A cloud-based security solution that provides a robust and secure framework for managing and enforcing security policies related to various resources managed in the cloud is disclosed. The cloud-based security solution is implemented by a centralized application programming Interface (API) system and a security zone policy enforcement system in a cloud service provider infrastructure. The centralized API system receives an API request that identifies an operation to be performed on a resource in the CSPI. The system determines, from the API request, compartment information and context information associated with the resource. Responsive to determining the compartment information and the context information associated with the resource, the system determines that the resource resides in a compartment that is associated with a security zone. The system then processes the API request and transmits a result of processing of the API request to a user of the centralized API processing system.

Abstract: A Ransomware Activity Detection System (RADS) characterizes historic read/write IO activity on a storage volume, and also characterizes historic data characteristics of the storage volume, such as the percentage reducibility of the data held in the storage volume. The RADS monitors the storage volume to identify differences between current read/write IO activity and historic read/write IO activity, as well as difference between current data characteristics of the storage volume and historic data characteristics of the storage volume. When the RADS detects a significant difference in read/write IO activity on a storage volume, that is coupled with a significant changes to the data characteristics of the storage volume, the RADS protects the storage volume and generates an alert of the possible occurrence of a ransomware attack. Protection may occur prior in connection with any bulk read operation to proactively protect storage volumes against ransomware attacks.

Abstract: Examples herein describe a scalable tweak engine and prefetching tweak values. Regarding the scalable tweak engine, it can be designed to accommodate different bus widths of data. The scalable tweak engine described herein includes multiple tweak calculators that can be daisy chained together to output multiple tweak values every clock cycle. These tweak values can be sent to multiple encryption cores so that multiple data blocks can be encrypted in parallel. Regarding prefetching tweak values, previous encryption engines incur a delay as the tweak value (e.g., a metadata value) for a data block is calculated. In the embodiments herein, the encryption engine can include an independent metadata engine that determines the metadata value for a subsequent data block while the current data block is being encrypted.

Abstract: Methods, systems, and computer storage media provide a privacy compliance notification indicating a database's level of compliance with a privacy policy after restoring the database to the database's backup copy. The database is associated with a database management engine. The database supports privacy-based first-class data entities. The privacy-based first-class data entities are database entities having privacy system-level metadata properties associated with data operations in a database language syntax. The privacy compliance notification may be generated based on determining whether a privacy database operation associated with a database journal and a privacy journal has been executed on a database since the database was restored to a backup copy of the database.

Abstract: According to one embodiment, a memory system includes a nonvolatile memory and a controller.

Abstract: Managing a software multi-ownership account including operations of registering software, setting a usage authority, and transferring a usage authority. The operation of registering the software includes the operations of: receiving, by a reception unit of a management server, a software registration request from a software manufacturer server; checking whether an authentication unit of the management server is a pre-approved manufacturer; and generating a smart contract transaction using time information at which the authentication unit of the management server is requested to register the software and string information of a software name. An authority can be effectively transferred to use software between users to another person by using a sub-access token interworked to a system user account, and by additionally issuing a sub-access token for multiple access authorities for one piece of software, a user is able to have multiple access authorities, thereby broadening the scope of software utilization.

Abstract: Malicious website detection has been very crucial in timely manner to avoid phishing. User privacy also needs to be maintained at the same time. A system and method for classifying a website URL have been provided. The system is configured to achieve end-to-end privacy for machine learning based malicious URL detection. The system provides privacy preserving malicious URL detection models based on Fully Homomorphic Encryption (FHE) approach either using deep neural network (DNN), using logistic regression or using a hybrid approach of both. The system is utilizing a split architecture (client-server) where-in feature extraction is done by a client machine and classification is done by a server. The client machine encrypts the query using FHE and sends it to the server which hosts machine learning model. During this process, the server doesn't learn any information about the query.

Abstract: Devices and techniques are generally described for peer-based anomalous rights detection. In various examples, a rights vector may be determined for a first individual, the rights vector representing rights held by the first individual. A nearest neighbor algorithm may be used to determine a set of individuals having similar rights to the first individual.

Abstract: Some network architectures include perimeter or edge devices which perform network address translation or otherwise modify data in a network traffic packet header, such as the source address. The modification of the source address prevents downstream devices from knowing the true or original source address from which the traffic originated. To address this issue, perimeter devices can insert the original source address in an X-Forwarded-For field of the packet header. Firewalls and related security services can be programmed to record the original source address in the XFF field in addition to the other packet information and to consider the original source address during security analysis. Using the original source address in the XFF field, services can determine additional characteristics about the traffic, such as geographic origin or associated user accounts, and use these characteristics to identify applicable rules or policies.

Abstract: A communication device and method are provided for communicating data, such as a cryptographic key, wirelessly to another communication device. The communication device and the other device each include an oscillator circuit portion, an inverter, a non-inverting buffer, and a switch for switching between the inverter and non-inverting buffer. A circular loop is formed wirelessly between the oscillator circuit portions of both devices by placing both communication devices near each other. A control circuit in each device measures a parameter such as frequency or waveform pattern of the circulating signal to determine how to position the switches. The oscillator circuit portions may be portions of the same oscillator distributed between the devices, such as a delay line-controlled oscillator or a chaotic oscillator. Inverting and not inverting the circulated signal changes the parameter of the signal so that it is difficult for an eavesdropper to learn the communication.
