The Carbon Black API Key Created or Retrieved detection rule identifies when a user creates a new API key or retrieves an existing key within the Carbon Black environment. This functionality is crucial for monitoring potentially malicious activities that could compromise API security. The rule leverages logs of the audit type from Carbon Black, specifically designed to capture events related to API key management. If a legitimate user, such as 'bob.ross@acme.com', retrieves or creates an API key, an event is logged with relevant details such as the time of the event, the IP address from where the action was taken, and descriptions of the actions performed. It has a medium severity and utilizes a deduplication period of 60 minutes to avoid repetitive alerts for similar events. This rule aids organizations in enforcing security policies around API usage and can help in detecting unauthorized or suspicious activities concerning API keys.
