“Those who are not prepared to recover their AD quickly from a malware attack will have a very hard time recovering the rest of their business any quicker as so many applications and services still depend on a well-functioning Active Directory,” he noted. Grillenmeier was a Microsoft MVP for Directory Services for 12 years, and his recent appointment to the post of chief technologist at Semperis is an opportunity for him to concentrate on helping companies protect themselves and their AD environments and, in worst-case scenarios, to recover quickly from a disaster. Over the years, special work for the German government further helped me to understand the intricate details of Active Directory security as this often required a lockdown of AD way beyond your standard corporate configuration,” he shared. “It’s those disasters that helped me to further dig into the details of the technology and better understand its weaknesses.

And from an infrastructure resilience and stability point of view, this statement is correct. “Active Directory is considered commodity technology these days – after all, this technology should have matured after more than 20 years of being in use. This makes Active Directory a valuable target for attackers and spur organizations to improve its security.īut Guido Grillenmeier says that the technology has been dropped from the corporate agenda.
Active Directory (AD), a directory service developed by Microsoft for Windows domain networks, is most organizations’ primary store for employee authentication and identity management, and controls which assets / applications / systems a user has access to.
