NIST Misses 2024 Deadline to Clear NVD Backlog
NIST has failed to meet its self-imposed deadline of clearing the NVD's backlog by the end of the fiscal year. Meanwhile, CVE's awaiting analysis have increased by 33% since June.

Provides low-level interfaces and helper methods for tracing in Azure SDK
The @azure/core-tracing package provides a common interface for adding tracing to Azure SDKs. It allows developers to collect detailed information about operations performed by Azure SDKs, making it easier to diagnose issues and optimize performance. The package is built on OpenTelemetry, a set of APIs, libraries, agents, and instrumentation that provide observability for applications.
Creating and managing spans
This feature allows developers to create and manage spans, which represent individual operations. Spans can be nested to represent complex operations composed of multiple steps. The code sample demonstrates how to create a tracing client, start a new span, and then end the span.
const { createTracingClient } = require('@azure/core-tracing');
const tracingClient = createTracingClient({
namespace: 'Microsoft.Azure',
packageName: 'AzureExample',
packageVersion: '1.0.0'
});
// Start a new span
cost span = tracingClient.startSpan('myOperation');
// End the span
span.end();
Integrating with Azure SDKs
This feature demonstrates how to integrate the @azure/core-tracing package with other Azure SDKs, such as Azure Storage Blobs. By passing a tracing client to the SDK's client constructor, developers can automatically collect tracing information for operations performed by the SDK.
const { DefaultAzureCredential } = require('@azure/identity');
const { BlobServiceClient } = require('@azure/storage-blob');
const { createTracingClient } = require('@azure/core-tracing');
const tracingClient = createTracingClient({
namespace: 'Microsoft.Azure',
packageName: 'Azure.Storage.Blobs',
packageVersion: '12.0.0'
});
const blobServiceClient = new BlobServiceClient(
'https://<my-storage-account>.blob.core.windows.net/',
new DefaultAzureCredential(),
{
tracingOptions: { tracingClient }
}
);
Jaeger client is a distributed tracing system that can be used to monitor and troubleshoot transactions in complex distributed systems. While it provides similar functionality to @azure/core-tracing in terms of tracing operations, Jaeger is a standalone system with its own backend and UI for visualizing traces, making it more suited for end-to-end tracing across multiple services and platforms.
This is the core tracing library that provides low-level interfaces and helper methods for tracing in Azure SDK JavaScript libraries which work in the browser and Node.js.
