Securing Service Accounts to Prevent Kerberoasting in Active Directory

As the cornerstone of enterprise IT ecosystems for identity and access management, Active Directory (AD) continues to serve as its pillar of support. It has been trusted to handle centralised authentication and authorisation processes for decades, enabling organisations to manage users, devices, applications, and services across a complex networked environment. 

The AD platform has long been in use and has played a critical role in the enterprise, yet its architecture and accumulated technical debt have made it a popular target for cyber adversaries, despite its widespread use and critical role. Threat actors have used various attack vectors to achieve their objectives, but Kerberoasting is one of the most commonly observed and effective techniques they employ. 

Kerberoasting is a sophisticated post-exploitation technique which allows cyber attackers to extract and crack service account credentials from Active Directory environments.
There are specific vulnerabilities in this vulnerability in the Kerberos authentication protocol. Kerberos is a trusted protocol that was created for the purpose of facilitating secure identity verification across potentially untrusted networks, such as the Internet. 

Kerberoasting is a play on words, which emphasises the way adversaries basically roast Kerberos service tickets in order to expose sensitive data.
