The Gartner report provides the following recommendations to CIO’s and organizations:

I&O leaders focused on securing data center infrastructure should

  • Ensure you are following backup vendor recommended best practices on securing your backup system and related infrastructure, and implement multifactor for console logins if possible.
  • Minimize backup system exposure by eliminating software or hardware components where the vendor no longer provides security updates.
  • Reduce the risk of losing backups during an attack by making use of immutable storage or an offline vault for at least one copy of your critical backup data.
  • Accelerate recovery from attacks by adding a dedicated tool for backup and recovery of Microsoft Active Directory.”
