T1562.008	Disable Cloud Logs

An adversary may disable cloud logging capabilities and integrations to limit what data is collected on their activities and avoid detection.

Cloud environments allow for collection and analysis of audit and application logs that provide insight into what activities a user does within the environment. If an attacker has sufficient permissions, they can disable logging to avoid detection of their activities. For example, in AWS an adversary may disable CloudWatch/CloudTrail integrations prior to conducting further malicious activity.^[1]

ID: T1562.008

Sub-technique of: T1562

Tactic: Defense Evasion

Platforms: AWS, Azure, GCP

Permissions Required: User

Data Sources: AWS CloudTrail logs, Azure activity logs, GCP audit logs

Mitigations

Mitigation	Description
User Account Management	Configure default account policy to enable logging. Manage policies to ensure only necessary users have permissions to make changes to logging policies.

Detection

Monitor logs for API calls to disable logging. In AWS, monitor for: StopLogging and DeleteTrail.^[2] In GCP, monitor for: google.logging.v2.ConfigServiceV2.UpdateSink.^[3] In Azure, monitor for az monitor diagnostic-settings delete.^[4] Additionally, a sudden loss of a log source may indicate that it has been disabled.
