What is Active Directory?
Active Directory (AD) is Microsoft's directory service for Windows networks. Domain controllers store users, computers and groups and provide sign-in through Kerberos, NTLM and LDAP. Group policy controls settings centrally and certificate services can be added.
Typical tasks
- Building and migrating domains and domain controllers.
- Cleaning up legacy items: old accounts, groups, policies.
- Protection against typical attacks such as Kerberoasting.
- Active Directory audit with a prioritised action list.
- Hybrid connection to Entra ID and Microsoft 365.
Benefits and limits
AD is proven, well understood and tightly integrated with Windows. It is also a preferred attack target: too many rights, legacy protocols and unmanaged service accounts are common weaknesses. For purely cloud-based environments Entra ID can be enough.
