Abstract: According to an embodiment, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise determining that an endpoint device has requested to discover a location of a protected resource that is protected by a gateway, determining whether the endpoint device has provided a token that is valid, and permitting the endpoint device to discover the location of the protected resource based on determining that the endpoint device has provided the token that is valid. The token indicates that the endpoint device successfully completed a first multi-factor authentication procedure in connection with accessing an authentication enforcement resource.

Abstract: Techniques for improving options templates are described. The techniques may be performed at least in part by a network edge device and may include receiving, from a network collector device, a request for an options template download, the request indicating whether a full options template or partial options template are requested. Based at least in part on whether a full options template or a partial options template are requested, the method may also include, transmitting a response to the network collector device including a segment of the options template, wherein each segment includes a flag indicating whether the segment is a last segment of at least one more segment will follow. Finally, the method may include receiving from the collector device and in response to transmitting a segment having the flag indicating the segment is a last segment, an acknowledgement that the full options template has been received.

Abstract: The present disclosure provides systems, methods, and computer-readable media for implementing security polices at software call stack level. In one example, a method includes generating a call stack classification scheme for an application, detecting a call stack during deployment of the application; using the call stack classification scheme during runtime of the application, classifying the detected call stack as one of an authorized call stack or an unauthorized call stack to yield a classification; and applying a security policy based on the classification.

Abstract: Embodiments herein describe a pluggable module that includes a ROADM implemented in a photonic integrated circuit (PIC). By implementing the ROADM in a PIC, the ROADM can be placed on smaller, pluggable modules (e.g., a Small Form-factor Pluggable (SFP) which can be a hot-pluggable network interface module).

Abstract: The fiber array units (FAUs) described herein include an FAU substrate with a coupling surface, an array of V-grooves formed in a FAU substrate, and a plurality of optical channels individually disposed in a respective V-groove of the array of V-grooves. The array of V-grooves and the optical channels are configured to position the optical channels along a curve defined in the coupling surface such that the optical channels are aligned with waveguides in a warped photonic device.

Abstract: In one embodiment, a method includes receiving a request to establish a path for a data stream from the first network apparatus to a second network apparatus, where the request is associated with a requested bandwidth for the data stream, and where the first network apparatus and the second network apparatus are connected by a link aggregation group including a number of physical Ethernet links, accessing bandwidth information representing a number of remaining bandwidths of the respective multiple of physical Ethernet links, determining that the requested bandwidth is not satisfied by any of the number of remaining bandwidths of the number of physical Ethernet links, and sending a response rejecting the request to establish the path.

Abstract: In one embodiment, a device instruments an application to generate OpenTelemetry trace data during execution of the application. The device detects an occurrence of a security event during execution of the application. The device identifies a correlation between the security event and the OpenTelemetry trace data. The device provides an indication of the security event in conjunction with the OpenTelemetry trace data, based on the security event being correlated with the OpenTelemetry trace data.

Abstract: Systems and methods for providing adaptive probe responses may be provided. An Access Point (AP) may receive a new probe response configuration, and compare the new probe response configuration to an old probe response configuration. The AP may determine that AP is operating in an ignore, a duplicate, or a hybrid mode based on the comparison of the new probe response configuration to the old probe response configuration. The AP may determine one or more probe response structures using the new probe response configuration and/or the old probe response configuration based on the mode the AP is operating in. When the AP receives a probe request from a Station (STA), the AP may send one or more probe responses in the probe response structures based the mode the AP is operating in.
