Vulnerability assessment is the process of identifying, quantifying, and prioritizing the cybersecurity vulnerabilities in a given IT system. Examples of such weaknesses are errors in application code, misconfigured network devices, and overly permissive access controls in a database. What is vulnerability assessment?

To further enrich log data for automated observability, it’s necessary to dynamically tie logs to distributed traces on the code level, user sessions in the app front-end, and the topology of your IT landscape. Collecting logs that aren’t relevant to their business case creates noise, overloads congested networks, and slows down teams.
