To secure backups, I use offline or air-gapped storage, implement multi-factor authentication (MFA) for access, and regularly test and update backups to ensure their integrity and functionality. These practices reduce vulnerability to ransomware attacks.

Protect backups from ransomware by following the 3-2-1 rule, using immutable and encrypted backups, isolating storage, implementing strict access controls, regularly testing restores, and keeping systems updated.

We monitor and audit our backup systems and prepare a properly document clear backup policy.Implementing a regular update & test backup policy.

The above suggestions are good practice. We have a replica of daily back to an offsite location as well. Regularly monitoring and checking integrity of the data as well. Strict access control is must.

There's one other part that does not get enough attention, user traing is also important because a user can get a usb flash drive and innocently plug in to the pc to find what's inside the drive and thatha can compromise the data if the drive is compromised.

Offline or Air-Gapped Backups: Store backups offline or in a segregated, isolated network to prevent ransomware from accessing and encrypting them. Multi-Factor Authentication (MFA): Enforce MFA for accessing backup systems, adding an extra security layer and making it harder for attackers to breach your backup environment. Regular Testing and Updates: Continuously verify backups to ensure they are up-to-date and functional. Conduct periodic tests to confirm data restoration processes work smoothly.

1. Use Offline or Air-Gapped Backups: Store backups on devices that are not connected to the internet or your primary network to prevent ransomware from accessing them. 2. Implement Regular Backup Schedules: Automate and regularly update backups to ensure they are recent and comprehensive, reducing the risk of data loss. 3. Enable Encryption and Access Controls: Encrypt backup files and use strong access controls to limit who can view or modify them, adding an extra layer of security.

Protecting backups from ransomware threats is crucial to ensure business continuity and data integrity. Here's how you can safeguard your backups effectively: Segment Backup Networks Physically or logically isolate backup systems from the primary network to limit exposure to ransomware that spreads laterally. Use Immutable or WORM (Write Once, Read Many) Storage Ensure backups cannot be altered or deleted by ransomware by using immutable storage systems or WORM-enabled backup solutions. Three copies of your data: production data and two backups. Store the backups on two different media types (e.g., disk and tape). Keep one backup offsite and preferably offline (air-gapped) or in immutable storage.
