Introduction: The Critical Role of Active Directory in Modern Enterprises
Active Directory (AD) is the backbone of most organizations’ networks, managing access and authentication for users, devices, and applications. Its central role makes it a prime target for cyber threats, necessitating robust security measures. However, traditional security solutions often fall short in addressing the complexities of modern hybrid environments.
The Active Directory Security Gap: A Pressing Concern
Despite its critical importance, Active Directory often suffers from significant security vulnerabilities. Common issues include:
- Shadow Admins: Unauthorized users with admin privileges hidden within nested groups.
- NTLMv1 Usage: Outdated and insecure authentication protocols.
- Stale User Accounts: Dormant accounts that can be exploited by attackers.
- Admins with SPN: Service Principal Names associated with admin accounts, vulnerable to Kerberoasting attacks.
- PrintNightmare Vulnerability: Exploits in the Windows Print Spooler service.
These vulnerabilities highlight the need for advanced solutions that go beyond traditional security measures.
SILVERFORT: Pioneering Unified Identity Protection
SILVERFORT stands out in the cybersecurity landscape with its innovative approach to identity protection. Unlike conventional solutions, SILVERFORT offers:
- Agentless and Proxyless Technology: This allows seamless integration without the need for modifications to endpoints or applications.
- Comprehensive Visibility: SILVERFORT provides a unified view of all users, resources, and authentication activities, enabling real-time threat detection and response.
- Enhanced MFA Capabilities: Extends multi-factor authentication (MFA) to resources that couldn’t be protected before, such as legacy applications and command-line tools.
Five Pillars of SILVERFORT’s AD Hygiene Enhancement
- Shadow Admin Detection and Mitigation:
- SILVERFORT identifies shadow admin accounts based on their privileges and permissions, even in complex environments.
- Example: At a Fortune 500 financial company, SILVERFORT detected 109 new shadow admins created by a single AD misconfiguration, significantly reducing attack exposure.
- NTLMv1 Usage Reduction:
- SILVERFORT monitors all authentications processed by Active Directory, identifying devices using NTLMv1 and sending alerts.
- Example: In a global manufacturer’s environment, SILVERFORT discovered that 5-8% of admin users still used NTLMv1, leading to a targeted reduction of this insecure protocol.
- Stale User Account Management:
- SILVERFORT automatically identifies stale users based on inactivity, helping organizations clean up their AD environment.
- Example: At a leading US retail company, SILVERFORT detected that 13% of user accounts were stale, enabling the company to disable/remove unused accounts and reduce costs.
- Admin with SPN Risk Mitigation:
- SILVERFORT detects admin accounts with SPNs, protecting them from Kerberoasting attacks through behavioral analytics and user profiling.
- Example: In a large healthcare provider’s AD environment, SILVERFORT discovered 8 admins with SPNs, reducing their attack surface exposure.
- PrintNightmare Vulnerability Protection:
- SILVERFORT analyzes authentication events and abnormal service behavior to detect and mitigate PrintNightmare vulnerabilities.
- Example: A large US school district detected and resolved PrintNightmare issues, reducing unnecessary authentications by about 70%.
Beyond Basic Hygiene: SILVERFORT’s Advanced Capabilities
SILVERFORT’s platform goes beyond basic AD hygiene by offering:
- Agentless and Proxyless MFA Implementation: SILVERFORT enforces MFA across all resources, including those previously unprotected.
- Comprehensive Service Account Protection: SILVERFORT provides visibility and monitoring of service accounts, preventing unauthorized usage.
- Real-time Identity Threat Detection and Response (ITDR): SILVERFORT detects and responds to identity threats in real-time, ensuring robust security across hybrid environments.
Case Studies: SILVERFORT in Action
SILVERFORT’s impact is evident in various real-world scenarios:
- Financial Sector: A Fortune 500 company reduced shadow admin accounts, enhancing security.
- Manufacturing: A global manufacturer minimized NTLMv1 usage, protecting admin credentials.
- Retail: A leading retailer cleaned up stale accounts, reducing costs and improving security.
- Healthcare: A healthcare provider mitigated Kerberoasting risks, securing admin accounts.
- Education: A school district addressed PrintNightmare vulnerabilities, enhancing overall security.
