What is CIS Control 11, And how do you implement this control?

CIS Control 11 Data Recovery- focuses on implementing secure data recovery practices to ensure the availability and integrity of critical data. It involves identifying critical data assets, establishing robust data recovery processes, regularly backing up data, encrypting backup data, and testing the effectiveness of data recovery procedures. Additionally, it emphasizes securing the storage of backup media and monitoring data recovery activities for anomalies or failures. By implementing these measures, organizations can effectively recover and restore critical data in the event of hardware failures, data corruption, or cyber incidents.

To implement CIS Control 11, the following steps can be taken:

Identify critical data:

Determine which data assets are critical for the organization's operations and prioritize them based on their importance.

Establish data recovery processes:

Develop and implement data recovery processes and procedures that address various scenarios such as hardware failure, data corruption, natural disasters, or cyber incidents.

Regularly back up data:

Implement a robust backup strategy to regularly back up critical data. This may involve using different backup mechanisms such as full backups, incremental backups, or differential backups.

Encrypt backup data:

Apply appropriate encryption measures to protect backup data from unauthorized access or tampering. Encryption should be used during transmission and storage of backup data.

Test data recovery procedures:

Regularly test the data recovery procedures to ensure they are effective and reliable. This includes conducting recovery tests, verifying the integrity of backed-up data, and assessing the recovery time objectives (RTO) and recovery point objectives (RPO).

Secure storage of backup media:

Safeguard the physical and logical security of backup media, whether they are tapes, disks, or cloud-based storage. Implement appropriate access controls and encryption to protect backup media from unauthorized access or theft.

Monitor data recovery processes:

Continuously monitor and review the effectiveness of data recovery processes. This includes logging and auditing backup and recovery activities, detecting any anomalies or failures, and promptly addressing any issues that arise.

By implementing these steps, organizations can enhance their data recovery capabilities and ensure the availability and integrity of critical data in case of incidents or disruptions.
