Auditing
Definition
The systematic recording and examination of activity across cloud infrastructure to ensure compliance, detect anomalies, and maintain accountability.
Use Cases
- Capital One: Tracking cloud configuration changes and user actions for security monitoring and compliance in a large AWS environment. — Capital One has publicly described using AWS-native logging and monitoring capabilities as part of its cloud security program. In practice, organizations like Capital One use AWS CloudTrail to record API activity across accounts, centralize logs, and support investigations into configuration changes and access events. (Improved traceability of administrative actions, faster incident investigation, and stronger evidence collection for regulated security and compliance processes.)
- Adobe: Maintaining visibility into administrative activity across large-scale cloud workloads to support governance and operational security. — Adobe has publicly discussed operating heavily in the cloud with strong observability and governance practices. In environments like this, audit logs are typically aggregated from native cloud services such as AWS CloudTrail, Azure Monitor Activity Log, or Google Cloud Audit Logs into centralized security and analytics platforms. (Better accountability across teams, quicker root-cause analysis for operational issues, and stronger support for internal controls and external audits.)
- Spotify: Monitoring infrastructure and access changes in Google Cloud to support reliability and security at scale. — Spotify has publicly shared its use of Google Cloud for parts of its platform. In a GCP environment, Google Cloud Audit Logs can be used to record administrative actions, policy changes, and service access events, then export them to SIEM or analytics tools for review. (Clear historical records of who changed what, improved troubleshooting, and stronger security oversight for cloud operations.)

Frequently Asked Questions
- What's the difference between Auditing and Monitoring?
- Auditing is about keeping a trustworthy record of actions that happened, such as who changed a firewall rule or deleted a storage bucket. Monitoring is about watching systems in near real time for health, performance, and alerts, such as CPU spikes or application errors. In simple terms, auditing helps answer 'who did what and when,' while monitoring helps answer 'what is happening right now.'
- When should I use Auditing?
- You should use auditing in every cloud environment, especially if you manage production systems, sensitive data, or multiple administrators. It is essential for compliance, security investigations, change tracking, and accountability. A good starting point is to enable native audit logging for all accounts and subscriptions, retain logs centrally, and protect them from tampering.
- How much does Auditing cost?
- Costs depend on the cloud provider, the types of logs collected, retention period, storage location, and whether logs are analyzed in a SIEM or logging platform. Some providers include basic control plane audit logs at no extra charge, while data access logs, long-term retention, cross-region delivery, and advanced analytics can increase costs. The biggest cost drivers are log volume, retention length, and downstream analysis.
