Active Directory Security
Directories, Hardened.
Access, Secured.
Active Directory environments face sophisticated attack vectors through credential theft, privilege escalation, and lateral movement techniques that exploit weak administrative models and inadequate security configurations.
At Cordant, we implement comprehensive Active Directory security through systematic vulnerability assessment, tiered administration deployment, and certificate services hardening that transforms directory infrastructure into resilient, secure identity foundations.
We eliminate Active Directory attack pathways whilst implementing defence-in-depth security controls that prevent credential compromise, restrict administrative access, and maintain regulatory compliance through proven security methodologies.
Our Active Directory security services encompass security assessment and hardening with vulnerability remediation, tiered admin model implementation for privilege segregation, and Active Directory Certificate Services hardening for PKI security.
Active Directory Security Assessment & Hardening
Execute comprehensive Active Directory security assessments that identify vulnerabilities and implement systematic hardening measures to protect against advanced persistent threats, credential theft, and privilege escalation attacks.
Our security assessment includes:
- Active Directory attack path analysis using BloodHound and custom assessment tools for privilege escalation identification
- Domain controller security hardening including secure baseline configuration, service hardening, and access control implementation
- Group Policy security configuration with administrative templates, security settings, and compliance policy enforcement
- Kerberos security implementation including armoring, constrained delegation, and authentication policy configuration
- LDAP security hardening with signing enforcement, SSL/TLS encryption, and secure authentication protocol implementation
- PowerShell security configuration with logging, execution policies, and administrative activity monitoring for threat detection
Tiered Admin Model Implementation
Implement comprehensive tiered administration models that segregate administrative privileges whilst preventing credential compromise and lateral movement through systematic privilege separation and access control frameworks.
Our tiered admin model covers:
- Administrative tier architecture design with Tier 0 (domain controllers), Tier 1 (servers), and Tier 2 (workstations) segregation
- Privileged Administrative Workstation (PAW) deployment with secure administrative environments and credential isolation
- Administrative account separation with dedicated administrative identities and restricted logon rights
- Jump server and bastion host implementation with secure administrative access and session recording capabilities
- Administrative forest deployment for high-security environments with trust relationship isolation and enhanced monitoring
- Credential Guard and Protected Users implementation with advanced authentication protection and credential theft prevention
Active Directory Certificate Services (ADCS) Hardening
Establish comprehensive ADCS security hardening that protects certificate authority infrastructure whilst implementing secure certificate issuance, template security, and PKI attack prevention across enterprise certificate services.
Our ADCS hardening includes:
- Certificate Authority security hardening including CA server protection, database security, and administrative access controls
- Certificate template security configuration with permission hardening, enrollment controls, and template vulnerability remediation
- Certificate enrollment security including authentication requirements, authorization controls, and certificate request validation
- CA database protection with backup encryption, access logging, and audit trail implementation for certificate lifecycle management
- Certificate revocation security including CRL protection, OCSP security, and certificate status validation hardening
- PKI attack prevention including ESC attack mitigation, certificate template abuse prevention, and certificate-based authentication security
