Name:Cisco Isovalent - Late Process Execution id:7f4b9b8e-5d6a-4a21-9e3f-0f1e8f2d1c3a version:5 date:None author:Bhavin Patel, Splunk status:production type:Anomaly Description:Detects process executions that occur well after a container has initialized, which can indicate
suspicious activity (e.g., interactive shells, injected binaries, or post-compromise tooling).
The analytic compares the process start time to the container start time and flags processes
launched more than 5 minutes (300 seconds) after initialization.
Data_source:
how_to_implement:The detection is based on process execution data generated by Cisco Isovalent Runtime Security. Ensure that Isovalent Runtime Security is deployed and configured in your Kubernetes environment to emit process_exec events. Configure the Cisco Security Cloud TA to collect these logs via HTTP Event Collector (HEC) and normalize them into the Splunk Common Information Model. This integration ensures that all relevant pod, container, and process activity is captured for monitoring and detection of suspicious behavior. known_false_positives:This activity may be triggered by legitimate administrative scripts, container images, or third-party operators that use cron for scheduled tasks, so please investigate the alert in context to rule out benign operations.
