They can reveal brute force attacks, credential stuffing, internal configuration drift, and usability problems. The post explains the risks of not monitoring these events, describes how to distinguish between attack patterns (brute force, credential stuffing, config errors, user mistakes), and provides a practical implementation guide: log failures with full context, centralize logs using tools like Elasticsearch or Splunk, build real-time dashboards, set anomaly alerts, and correlate auth failures with other system metrics. Compliance frameworks like SOC 2, HIPAA, and PCI DSS also require this monitoring. ## Full article daily.dev links to this article rather than hosting it.
