Alvaka Networks provides patching assistance for those needing to secure their systems immediately from the threat of CVE-2020-1472 | Netlogon Elevation of Privilege Vulnerability (Zerologon).

CVE-2020-1472 | Netlogon Elevation of Privilege Vulnerability

Following Microsoft’s best practice recommendations, Alvaka Networks will:

  1. UPDATE your Domain Controllers with an update released August 11, 2020 or later.
  2. FIND which devices are making vulnerable connections by monitoring event logs.

  4. ENABLE enforcement mode to address CVE-2020-1472 in your environment.
