In light of the persistent threat of ransomware attacks, healthcare organizations need to take extra steps to ensure their systems are adequately backed up - and that those backups are protected, says Martin Littmann, CTO and CISO of Kelsey-Seybold Clinic in Houston.

Organizations need to fortify their business continuity plans - and that includes paying extra attention to backups so that compromised data can be fully recovered, Littmann says in an interview with Information Security Media Group.

Kelsey-Seybold Clinic has implemented "immutable snapshots and backups," he explains. "Data that's backed up in one array is replicated in another array and possibly to a tertiary array. On each of those arrays, we might use unique identities or dedicated services accounts to manage the access to those arrays."

This strategy amounts to "using an obfuscation approach in addition to the backup and recovery," says Littmann, who will be a featured speaker at ISMG's March 16 Virtual Cybersecurity Summit: Healthcare.

In this interview (see audio link below photo), Littmann also discusses:

  • Lessons learned from Kelsey-Seybold's experience dealing with a ransomware incident;
  • Data center business continuity security considerations;
  • The broadening cyberattack landscape during the COVID-19 pandemic.

Littmann is the CTO and CISO for Kelsey-Seybold Clinic, a large multispecialty clinic system serving the Houston area. He's responsible for IT architecture and strategy, infrastructure and network and information security. He has over 30 years of global business experience spanning healthcare, energy, manufacturing and consulting. He has served as the healthcare sector chief for the Houston InfraGard chapter, and he has served on numerous tech company customer advisory boards.
