For a NERC CIP-regulated entity, clean data onboarding is not just good hygiene. It is evidence. The same discipline that gives you accurate parsing and right-sized volume also produces the log retention, security-event capture, and change records that an audit asks for. Do it well once and you stop treating compliance as a separate project bolted on after the fact.
Here is how the onboarding workflow lines up with the CIP standards, control by control.
Every new source should carry a BES impact rating (High, Medium, or Low) and an asset type: BCA, PCA, EACMS, PACS, or EAP. Flag whether the source is or contains BES Cyber System Information. This classification drives everything downstream, from who gets access to how long you retain the data.
Confirm need-to-know access to both the data and the onboarding tooling, and apply least privilege on the target index (CIP-004). Keep the data path inside the authorized Electronic Security Perimeter, and confirm your forwarder or Cribl routing does not egress BCSI to an unapproved destination (CIP-005 and CIP-011). This is the step teams most often skip when a source is added under time pressure.
CIP-007 R4 is where onboarding and compliance meet most directly. Confirm the source captures the required security events: successful and failed authentication, account management, object access, detected malicious code, and access attempts at Electronic Access Points (R4.1). Set index retention with frozenTimePeriodInSecs so event logs are held for at least 90 consecutive calendar days (R4.3). Fire real-time alerts on detected security events, and monitor for logging and ingest failures so a data gap does not go unnoticed (R4.2). And schedule review of a summary or sample of logged events at intervals no greater than 15 days (R4.4).
Open a documented change and capture the current baseline before you modify anything. Build and test the source type in a dev or non-production index before promoting to production. Keep your props.conf, inputs.conf, and onboarding scripts under version control, which gives you the who-changed-what-and-when trail that CIP-010 expects. Retain evidence that 90 days were held historically, separate from the live logs.
None of this works if the data does not parse cleanly, so source typing still comes first. See The Great Eight for the props.conf settings that get event breaking and timestamps right, and Data onboarding without the rework for the full workflow. For the broader threat picture driving these mandates, our take on OT security and NERC CIP is still worth a read.
