Active Directory - Cyber Security Architect


  • Met with leadership and project managers on a regular basis to inform them of the status of the project and the state of the environment.
  • Built a team with engineers and analysts to design, build and implement new security solutions across the enterprise. Centrify Privileged Access Management (PAM) for restricting rights to just what is needed and the Privileged Access Services (PAS) portal for restricting access were deployed as part of this effort.
  • Deployed Okta Multi-Factor Authentication (MFA) to secure enterprise applications using two factor authentication globally.
  • Created documentation for the enterprise to describe the architecture and provide clarity on security. This included creating Standard Operating Procedures (SOPs) and Knowledge Items (KIs) for the operational support staff to better support the infrastructure with the new technologies involved.
  • Redesigned the Active Directory Disaster Recovery plan to integrate with the corporate plan. This included a new backup solution by Quest, Recovery Manager Active Directory DR edition to automate backup and recovery. Testing of the solution involved a full recovery in a lab.
  • Redesigned and rebuilt the internal PKI infrastructure using Microsoft Certificate Services to fall in line with industry standards and allow for Certificate Lifecycle Management.
  • Products from Quest were deployed to constrain support personnel to what was needed. GPOAdmin allowed better management of GPOs and version control. Active Roles allowed support personnel to manage Active Directory objects without excessive delegation. Change Auditor is used to provide an audit trail and alerting regarding changes within Active Directory in additional to compliance auditing.
  • Delivered training for teams across the enterprise on concepts and technologies to raise skill levels and bring awareness to the new technologies.


Identity and Security Engineer


  • Designed and implemented solutions to harden the Active Directory infrastructure. This involved developing scripts and software in Visual Studio to analyze the security. Solutions were developed that include using delegations within Active Directory, authentication silos and group policy.
  • Developed and automated monitoring of the global infrastructure providing a better visual picture of the security and stability leveraging the current SCOM infrastructure, building custom scripts and creating dashboards.
  • Acted as lead engineer on migration to Service Now from the previous service desk system. Developed security solutions for best deployment of the system globally.
  • Worked with the global security team to integrate the various identity platforms security monitoring into the SIEM solutions using multiple solutions including Microsoft Advanced Threat Analytics (ATA) and Tenable.
  • Streamlined redundant processes and procedures to eliminate waste and improve efficiency.
  • Designed and delivered software based on Microsoft Just Enough Access (JEA) to allow delegation of tasks to tier 1 and 2 global teams in a secure manner leading to shorter incident resolution times and shifting the tasks to junior level teams.
  • Drove all phases of the enterprise identity and access management disaster recovery project to successful completion, including application availability initiatives (e.g. failover-clustering, Data Protection Manager, VMware) and the implementation of single site fail-over and recovery options.
  • Mentored multiple global teams on best practices, in depth troubleshooting and information security aspects. Delivered training for .Net (PowerShell).


Security Analyst


  • Maintained an Active Directory infrastructure consisting of multiple locations, 200K+ users and 300K+ servers/workstations.
  • Devised analytical processes to identify access within the infrastructure. Large data set analysis was used to find edge/node relationships such as group and user object nesting across multiple Active Directory forest/domains.
  • Implemented Microsoft Advanced Threat Analytics (ATA) to provide insight into the security of the infrastructure.
  • Created in depth monitoring of Active Directory performance and security using System Center Operations Manager (SCOM) and Audit Collection Services (ACS).
  • Deployed Active Directory Federated Services (ADFS) and Active Directory Lightweight Directory Services (ADLDS).
  • Identified control gaps from audits and developed mitigation plans for gap closure.
  • Consulted with various projects on issues ranging from Active Directory integration to identity management.
  • Deployed smart cards integrate with Active Directory to allow secure logon capability for all support personnel with access to sensitive assets.
  • Provided analysis of various projects for their security posture. The results were communicated with leadership along with mitigation plans.
  • Deployed Vintella Authentication Services to allow integration of UNIX/Linux server with Active Directory.
  • Conducted, in association with Microsoft, infrastructure health checks to determine areas of improvement and executed the recommendations of the findings.
  • Developed .Net code to solve in house written application issues.
  • Created troubleshooting tools in .Net to automate processes and simplify addressing issues in the infrastructure.
