Threat findings are generated by\n[threat detectors](/security-command-center/docs/concepts-security-sources#threats) when they detect\na potential threat in your cloud resources. For a full list of available threat findings, see [Threat findings index](/security-command-center/docs/threat-findings-index).\n\nOverview\n\nOne of the binaries or configuration files in the `pam.d` directory\nwas modified. Pluggable authentication modules (PAM) are widely used for\nauthentication in Linux. Attackers might modify the binaries or configuration\nfiles to establish persistent access.\n\nThis is a file monitoring detector and it\nhas [specific GKE version requirements](/security-command-center/docs/how-to-use-container-threat-detection#gke-version).\n\nThis detector is disabled by default. For instructions on how to enable it,\nsee [Testing\nContainer Threat Detection](/security-command-center/docs/how-to-test-container-threat-detection).\n\nDetection service\n\n[Container Threat Detection](/security-command-center/docs/concepts-container-threat-detection-overview)\n\nHow to respond\n\nTo respond to this finding, do the following:\n\nReview finding details\n\n1. Open the `Collection: Pam.d Modification` finding as directed in\n [Reviewing findings](/security-command-center/docs/how-to-investigate-threats#reviewing_findings).\n Review the details in the **Summary** and **JSON** tabs.\n\n2. Identify other findings that occurred at a similar time for this resource.\n Related findings might indicate that this activity was malicious, instead of\n a failure to follow best practices.\n\n3. Review the settings of the affected resource.\n\n4. Check the logs for the affected resource.\n\nResearch attack and response methods\n\nReview the MITRE ATT\\&CK framework entry for this finding type:\n[Collection](https://attack.mitre.org/tactics/TA0009/).\n\nWhat's next\n\n- Learn [how to work with threat\n findings in Security Command Center](/security-command-center/docs/how-to-investigate-threats).\n- Refer to the [Threat findings index](/security-command-center/docs/threat-findings-index).\n- Learn how to [review a\n finding](/security-command-center/docs/how-to-investigate-threats#reviewing_findings) through the Google Cloud console.\n- Learn about the [services that\n generate threat findings](/security-command-center/docs/concepts-security-sources#threats)."]]
