![]() If your domain is based on a Server 2012 R2 domain functional level, you can implement domain controller-side protections for protected users. These are not available if you have a server domain infrastructure based on Server 2012 R2. ![]() Finally, Kerberos clients successfully authenticating with the PKInit Freshness Extension will get the fresh public key identity SID. This configuration is also known as "smart card required for interactive logon." Domain Controllers can support allowing network NTLM when a user is restricted to specific domain-joined devices. Server 2016 Domain functional level allows domain controllers that can support automatic rolling of the NTLM and other password-based secrets on a user account configured to require PKI authentication. For example, with Server 2016, Privileged access management (PAM) using Microsoft Identity Manager (MIM) are available with Server 2016 forest functional levels. The larger the firms, the more likely you merely connected the multiple systems by whatever means possible.īut neglecting to take time to review the existing infrastructure, folding in what worked and throwing out what didn't, introduced complexity, insecure permissions, and typically a lack of understanding of network infrastructure.Ĭertain security features are only available with certain domain and forest functional levels. ![]() But in doing so, we made choices that not only added complexity but increased weaknesses in our networks.Ĭase in point was the long-standing tradition of setting up domain trust - migrating or joining the existing domain was just not done rather, a domain trust and possibly multiple forests were set up and you went on with your business. It was standard procedure to disable workstation firewalls, enable server message block (SMB v1) protocols and in general do everything the C-suite wanted. In the past, security decisions were rarely included in the planning when it came to combining networks after companies merged - just getting the two systems up and running and talking to each other came first and foremost. ![]()
