Dump On-Premise Microsoft Active Directory
Companies with both an on-premises version of Active Directory as well as Azure Active Directory are living in the worst of all possible worlds since they’re having to defend against cloud threats, on-premise threats, as well as the mechanisms that Active Directory uses to stay in sync across cloud and on premises, which were exploited by the SolarWinds hacker, according to Proofpoint’s Ryan Kalember.
Kalember, who is Proofpoint’s executive vice president of cybersecurity strategy, urged organizations to fully migrate to Azure Active Directory or Okta Universal Directory to eliminate both on-premise threats as well as hybrid threats like delegated admin abuse, which Kalember said is a vulnerable configuration that Microsoft had been aware of for years and didn’t actually fix.
Companies that get their directory fully in the cloud go from dealing with three different categories of very complicated to model risk to just one, Kalember said. Companies often have many applications that have always talked to the on-premise domain controller, and following Microsoft or Okta’s protocols to move that user identity and authentication to the cloud can be time-consuming, but he said it’s worth it.
