State-Backed Hackers Targeting All Exchange Servers

The vulnerability results from the Exchange Server failing to properly create unique cryptographic keys at the time of installation.

Make “Identity Utopia” a Reality in Active Directory

When making a decision to move production workloads to the cloud, one of the first things that is considered is cost. However, there are frequently many hidden costs that are not factored into the cloud decision until they appear in the real world.

What new burdens are placed on the IT team if end users, now managing identities in two places, constantly require assistance to access their work? What costs are associated with securely authenticating end users to the workload?
