Data Recovery Policy Template for CIS Control 11
In the cybersecurity triad – Confidentiality, Integrity, and Availability (CIA) – the availability of data is, in some cases, more critical than its confidentiality. Enterprises need many types of data to make business decisions, and when that data is not available or is untrusted, then it could impact the enterprise. An easy example is whether information to a transportation enterprise. When attackers compromise assets, they make changes to configurations, add accounts, and often add software or scripts. These changes are not always easy to identify, as attackers might have corrupted or replaced trusted applications with malicious versions, or the changes might appear to be standard-looking account names. Configuration changes can include adding or changing registry entries, opening ports, turning off security services, deleting logs, or other malicious actions that make a system insecure. These actions do not have to be malicious; human error can cause each of these as well. Therefore, it is important to have an ability to have recent backups or mirrors to recover enterprise assets and data back to a known trusted state.
This policy template is meant to supplement the CIS Controls v8. The policy statements included within this document can be used by all CIS Implementation Groups (IGs) but are specifically geared toward Safeguards in Implementation Group 1 (IG1).
