Can you keep Linux-based ransomware from attacking your servers?

David Geer | Dec. 7, 2015
Patching pressures don't make Linux ransomware any easier to take.

Additional security practices including running certain apps in containers to isolate them from the rest of your systems, says Ben Johnson, chief security strategist, Bit9+Carbon Black. “An app or web server in one container can’t leave it to attack an app in a different container. Even if an attack landed in one container, it wouldn’t get back out to attack something else,” says Johnson.

There are well-known forms of controls that help, too. “Use whitelisting to approve apps that can run on your web server and block everything else,” says Johnson. Hardening systems including closing unused ports goes hand in hand with application blocking.

Good general IT hygiene is the best measure. “It would get rid of 90-percent of attack problems,” says Johnson.
