Non-human identities (NHIs) arise from the increased utilization of automation and cloud services, making Active Directory service accounts critical points of vulnerability. Despite their significance, many organizations overlook the specific security needs of these accounts, which often have excessive permissions and inadequate monitoring measures. Given the rapid evolution of software interactions, IT and security teams must shift their focus to securing NHIs within their infrastructures to prevent possible breaches.
One common risk is the use of Kerberoastable accounts, which allow attackers to exploit the Kerberos protocol for harvesting password hashes. Such vulnerabilities can result in unauthorized access that remains unnoticed for extended periods due to the passive nature of these attacks. Additionally, unconstrained Kerberos delegation creates avenues for impersonation that compromise sensitive data and applications, necessitating stringent security measures in the management of service accounts.
To mitigate these risks, organizations are encouraged to conduct thorough reviews of their service account configurations, implement strong encryption protocols for service tickets, and prioritize regular access reviews to ensure that permission levels are appropriate. By taking these actions, companies can significantly decrease their exposure to attacks targeting their NHIs, ultimately strengthening their cybersecurity posture.
