Abstract: A method for securely sharing validation information of one or more data files stored on different cloud servers using distributed ledger technology includes requesting access to the data files and calculating a hash thereof. A structured Merkle tree is constructed using the hash and additional hashes of other data files for which a user has not granted access, but has used to construct a corresponding Merkle tree for which the user has committed a root value to a main blockchain. It is checked whether the root value of the Merkle tree is the same as the one the user has committed, and whether the hash of the data files is stored in a block of a satellite blockchain linked to the main blockchain and operated by a subset of nodes of the main blockchain that trust one another.

Abstract: A graphical user interface provides network security administrators a tool to quickly and easily create one or more courses of action for automatic response to a network threat. The courses of action are hardware and system agnostic, which allows a common response task to be implemented by an underlying response engine for any or multiple similar-function devices regardless of brand or version. The course of action builder allows the administrator to use a simple, graphic-based, business modeling concept to craft and design security response processes rather than having to hard code response routines specific to each piece of hardware on the network. The graphic interface model allows the user of the threat response software incorporating the course of action builder to easily understand the overall flow and paths the response may take, as well as understand the data requirements and dependencies that will be evaluated.

Abstract: A method for uniquely authenticating a device provides for receiving a scoping request, allocating a scope ID responsive to the request, and storing one or more device identification credentials in a database. Each device identification credential stored in the database includes the allocated scope ID and a device ID provided within the scoping request. The method further provides for receiving a registration request specifying a device identification credential and authenticating the specified device identification credential by confirming a match between the specified device identification credential and one of the device identification credentials stored in the database. The method further provides for provisioning the device with initial configuration information responsive to the authentication.

Abstract: A device such as a network-attachable data transfer device may be configured to operate in a cluster to coordinate the storage of data. A cluster manifest may include data and/or metadata related to devices of the cluster. In some cases, a cluster manifest may include, for each of one or more devices of a cluster: an encrypted payload; an identifier associated with the particular device; and an encrypted data entry. The encrypted payload may encode a cryptographic payload key used in part to perform storage operations. The encrypted data entry may include one or more encrypted partitions that are each decryptable by a different security module of the device. The decrypted partitions may be assembled to form a cryptographic key that may decrypt the encrypted payload. The cluster manifest may be provided to a locked device of a cluster as part of a process for unlocking the locked device.

Abstract: An execution of a data object is identified by a computing device. In response to identifying the execution of the data object, it is determined that the data object has requested a sensitive action of the computing device before interacting with a user of the computing device. In response to determining that the data object has requested the sensitive action, the data object is classified as a high-risk data object.

Abstract: The invention relates to a method and an apparatus for encrypted communication between a client and a server, wherein the communication comprises request messages, each with request elements, and response messages, each with response elements. Request elements and response elements can comprise data. It is an object of the invention to hamper or prevent unauthorized access to the data during communication and also during storage and processing on the server. In this case, it is assumed that the communication channel and also the server itself are not trustworthy and neither client nor server provide measures or are adaptable in order to counter said risks of unauthorized access, for example by means of cryptographic methods.

Abstract: An example method may include detecting, by an operating system component of a computing device, that a client requesting a network connection is operating in a non-persistent mode that prevents tracking of network locations accessed by the client; in response to the detecting, performing privacy enhancing operations before establishing the network connection for the client. The privacy enhancing operations include: broadcasting network messages to discover networks without using previously stored information related to the networks; receiving network identifying information from the networks; providing the network identifying information for the networks to the client; requesting the client to perform media access control (MAC) address randomization; receiving a random MAC address and authentication information for a connection to a network selected from the networks; and authenticating the client; and causing the network connection to be established upon a successful authentication of the client.

Abstract: A method and system for authenticating a device, board, assembly or system includes obtaining or processing test/scan information provided via extraction of ECID or other unique identifying information regarding a board. A re-authentication process is performed to verify that the board contains only legitimate ECID or other uniquely identified devices, via comparison of re-extracted codes of devices at known positions against a reference record, the reference record being established by an initial authentication process that utilizes information regarding authentic/unique ECID or other uniquely identified codes of devices delivered to populate the board to derive the reference record for the device.

Abstract: This disclosure relates to enhanced overlay network-based transport of traffic to and from customer branch office locations, facilitated through the use of the Internet-based overlay routing. A method of selecting an ingress edge region of the overlay network begins by mapping a service hostname to an IKEv2 destination of an outer IPsec tunnel associated with a first overlay network edge. An IKEv2 session is established from the first overlay network edge to the customer router. Upon tunnel establishment, a secondary lookup is performed to determine whether the first overlay network edge is an appropriate ingress region. Based on a response to the secondary lookup, a IKEv2 redirect is issued to a second overlay network edge. A new tunnel is then established from the second overlay network edge to the customer router. Thereafter, an additional lookup may also be performed to determine whether the second overlay network edge remains an appropriate ingress region.

Abstract: This invention discloses systems and methods for detecting vulnerabilities in IT assets by utilizing crowdsourcing techniques. A corpus containing vulnerability data of IT assets with known vulnerabilities is established. Vulnerability data in the corpus comprises security aspects or attributes related to the IT assets. The security aspects of an IT asset constitute its attack surface which is represented as a feature vector in a feature space. A determination is made as to how similar/close a target asset whose unknown vulnerabilities are to be detected, is to the rest of the IT assets in the corpus. This determination is made based on a measure of similarity/distance between the respective feature vectors in the feature space. Based on the review of similarity results by a community of researchers/experts, a determination of unknown vulnerabilities in the target system is made.
