Benchmark: 10.5 Interview system administrators and examine system configurations and permissions to verify that audit trails are secured so that they cannot be altered
Description
Often a malicious individual who has entered the network will attempt to edit the audit logs in order to hide their activity. Without adequate protection of audit logs, their completeness, accuracy, and integrity cannot be guaranteed, and the audit logs can be rendered useless as an investigation tool after a compromise. This control checks secure audit trails so they cannot be altered.
Usage
Install the mod:
mkdir dashboardscd dashboardspowerpipe mod initpowerpipe mod install github.com/turbot/steampipe-mod-aws-complianceStart the Powerpipe server:
steampipe service startpowerpipe serverOpen http://localhost:9033 in your browser and select 10.5 Interview system administrators and examine system configurations and permissions to verify that audit trails are secured so that they cannot be altered.
Run this benchmark in your terminal:
powerpipe benchmark run aws_compliance.benchmark.pci_dss_v321_requirement_10_5Snapshot and share results via Turbot Pipes:
powerpipe benchmark run aws_compliance.benchmark.pci_dss_v321_requirement_10_5 --shareBenchmarks
- 10.5.2 Current audit trail files are protected from unauthorized modifications via access control mechanisms, physical segregation, and/or network segregation
- 10.5.3 Current audit trail files are promptly backed up to a centralized log server or media that is difficult to alter
- 10.5.4 Logs for external-facing technologies (for example, wireless, firewalls, DNS, mail) are written onto a secure, centralized, internal log server or media
- 10.5.5 Examine system settings, monitored files, and results from monitoring activities to verify the use of file-integrity monitoring or change-detection software on logs
