Abstract: In one embodiment, a device obtains transaction data regarding a transaction attempted by a client of an online application to access confidential information within the online application. The transaction data is captured by instrumentation code inserted into the online application at runtime. The device permits, based on a policy, the transaction to complete within the online application. The device determines, based on the policy, a set of one or more client-side functions to disable during the transaction. The device instructs an agent executed by the client to disable the set of one or more client-side functions during the transaction.

Abstract: Techniques for initiator-based data-plane validation of segment routed, multiprotocol label switched (MPLS) networks are described herein. In examples, an initiating node may determine to validate data-plane connectivity associated with a network path of the MPLS network. The initiating node may store validation data in a local memory of the initiating node. In examples, the initiating node may send a probe message that includes a request for identification data associated with a terminating node. The terminating node may send a probe reply message that includes the identification data, as well as, in some examples, a code that instructs the initiating node to perform validation. In examples, the initiating node may use the validation data stored in memory to compare to the identification data received from the terminating node to validate data-plane connectivity. In some examples, the initiating node may indicate a positive or negative response after performing the validation.

Abstract: A method, computer system, and computer program product are provided for controlling data access and visibility using a context-based security policy. A request from an endpoint device to receive data is received at a server, wherein the request includes one or more contextual attributes of the endpoint device including an identity of a user of the endpoint device. The one or more contextual attributes are processed to determine that the endpoint device is authorized to receive the data. A security policy is determined for the data based on the one or more contextual attributes. The data is transmitted, including the security policy, to the endpoint device, wherein the endpoint devices enforces the security policy to selectively permit access to the data by preventing the endpoint device from displaying the data to an unauthorized individual.

Abstract: An electronic device of a content producer generates a chunk of data, associates a location-independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key. A user device may obtain the public key and use it to verify the chunk of data.

Abstract: Techniques and mechanisms for providing integrity verified paths using only integrity validated pods of nodes. A network service mesh (NSM) associated with a first pod may locally generate a nonce and provide the nonce to the first pod, where the request includes a request for an attestation token. Using the nonce, the first pod may generate the attestation token and reply back to the NSM. The NSM may generate a second request for an attestation token and forward it to a NSE pod, where the request includes a second locally generated nonce generated by the NSM. The NSE pod may generate the second attestation token using the second nonce and reply back to the NSM. The NSM may then have the attestation tokens verified or validated by a certificate authority (CA) server. The NSM may thus instantiate an integrity verified path between the first pod and the NSE pod.

Abstract: Aggregation of cross domain service level indications provide an estimate of available end to end error budget within a service chain of a network system. In some embodiments, service level indications are obtained from a plurality of sub-domains, and aggregated to determine an end to end reliability score. The end to end reliability score is then distributed one or more of the sub-domains. The sub-domains then consider whether to implement a change based on local service level indications as well as the end to end reliability score. In other embodiments, a sub-domain requests approval to implement a change from an error manager. The error manager consults the end to end reliability score to determine whether adequate margin exists in the service chain to allow the change to occur, while still meeting service level objectives of the service chain. The error manager conditionally approves the request based on the determination.

Abstract: In one embodiment, a device obtains data regarding a transaction attempted by a user account within an online application that is captured by instrumentation code that is inserted into the online application at runtime, wherein the user account has sufficient privileges within the online application to perform the transaction. The device makes an inference about the data regarding the transaction using a behavioral model. The device determines, based on the inference, a mitigation action for performance within the online application according to an enforcement policy. The device enforces the mitigation action within the online application.

Abstract: Methods and devices provide fault injection testing techniques in a production network environment without risking service outages for hosted computing services, by providing examples of a remote network controller configured to communicate with network devices of a network; a remote fault injection communication protocol configuring a remote network controller in communication with a network device to signal a failure injection; and a failure injection module configuring a network device to configure a network device processor to implement a failure injection signaled according to the remote failure injection communication protocol. The method includes a network controller transmitting a failure injection signal in a control plane packet over a network connection to a network device, and the network device creating a child process by executing, in a dedicated runtime environment, a copy of one or more processes impacted by a parsed failure type.

Abstract: Presented herein are methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within an IPv6 network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet (e.g., in the packet header) that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the IPv6 network are signaled to capture or further inspect the packet for capture.

Abstract: Techniques and mechanisms for providing continuous integrity validation-based control plane communication in a container-orchestration system, e.g., the Kubernetes platform. A worker node generates a nonce and forwards the nonce to a master node while requesting an attestation token. Using the nonce, the master node generates the attestation token and replies back to the worker node with the attestation token. The worker node validates the attestation token with a CA server to ensure that the master node is not compromised. The worker node sends its authentication credentials to the master node. The master node generates a nonce and forwards the nonce to the worker node while requesting an attestation token. Using the nonce, the worker node generates the attestation token and replies back to the master node with the attestation token. The master node validates the attestation token with the CA server to ensure that the worker node is not compromised.

Abstract: Techniques for utilizing a cloud service to compute an end-to-end SLA-aware path using dynamic software-defined cloud interconnect (SDCI) tunnels between a user device and an access point-of-presence (POP) node and inter-POP tunnels of the SDCI. The cloud service may include a performance aware path instantiation (PAPI) component including a POP database for storing performance metrics associated with the POPs of the SDCI, an enterprise policy database for storing user specific policies, and/or a path computation component. The path computation component may compute the path, based on the user specific policies, performance metrics associated with the POP nodes, and/or real-time contextual data associated with the user device and/or destination device. The path may include a first tunnel between the user device and the most optimal access POP node of the SDCI and a second tunnel between the access POP node, through the internal POP nodes, and to the destination device.

Abstract: Methods are provided in which a network device hosts distinct network access resources that are managed by different entities. The method includes obtaining a request for partitioning one or more network resources of an on-premise network device for connecting one or more endpoints to a first network managed by a first entity. The on-premise network device connects one or more endpoints to a second network managed by a different entity. The method further involves partitioning, based on the request, the one or more network resources and connecting the one or more endpoints to the first network using the one or more network resources. The one or more network resources are managed by the first entity while at least one other network resource of the on-premise network device is managed by the different entity and is associated with connecting the one or more endpoints to the second network.

Abstract: This disclosure describes using a dynamic proxy for securing communications between a source within a cloud environment and an application container. The techniques include intercepting traffic directed to an application container, analyzing the traffic and traffic patterns, and allowing or preventing the traffic from being delivered to the application container based on the analysis. A traffic analysis engine may determine whether the traffic is considered safe and is to be allowed to be delivered to the application container, or whether the traffic is considered unsafe and is to be prevented from being delivered to the application container, According to some configurations, the address(es) to the network interfaces (e.g., WIFI or Eth0) are abstracted to help ensure security of the application containers.
