Mar 2016 - nowStarted working with the “High Value Asset Operations” team (HVAOps). This team owns the “Hardware Security Module” (HSM) infrastructure and manages the PKI governance for the company. Here is a list of the duties I have performed in this role:- Update and improve auditable procedure documentation. Most noticeable changes were a reduction to the number of signatures required without compromising integrity and the number of steps to follow allowing for a better flow in the process.- Electronic lock management for our secure area. This would involve the creation of new key fobs and performing periodically pin changes to them.- HSM operational duties like firmware upgrades, initialization and decommissions.- Biannual inventory of assets and quarterly security access audits.- Developed a monitor for CRL (Certificate Revocation List) expirations using C#, Service Fabric, Azure RBAC and Azure Storage. - Developed a diagnostic page for PKI tools that would validate that all components and permissions are present for the tool to function correctly. Built using C#.- Execute “Business Continuity Disaster Recovery” scenarios and work with auditors to maintain our Web Trust compliance.- Performed “User acceptance testing” on PKI tools. Also, create detailed bugs to be fixed by software engineers. - Performed certificate approvals during the fulfillment process.- I have also participated in “Capture the flag (CTF)” events where we try to hack a sandbox website by exploiting multiple functionalities on the website. This included SQL injections, altering cookies, manipulating sessions and others. Show less Role change within the “CodeSign” team. I also started working directly with the codesigning of software to be released on Apple platforms. Here is a list of the duties I have performed in this role:- Full stack software engineering using PHP and C#.- Led project to add a load balancer (HLB) to the Apple Sign system. This involved setting up meetings with the network team, gathering and analyzing network information of the current infrastructure, performing tests for the applied changes, creating a user guide (WIKI), and validating that the HLB would not affect the service.- Adapted the service to Apples ongoing changes like enabling file “hardening” so that they could be notarized by Apple to be released to the market, and upgrading MacOS support with every new release.- Move away from legacy encryption certificates for decrypting credentials by integrating Azure Key Vault to our “CodeSign” service. This eliminates the risk of incidents and toil of manual processes for the team and puts the service closer to being fully unattended when it comes to operational duties.- Improve the Azure file transfer process by moving away from native PHP and replacing it with the AZCopy application. Through testing, I was able to see a vast improvement compared with the current process we had being using. It showed that the transfer process, while encountering connectivity issues, can perform 90% better. Show less Started working with the “CodeSign” team where I maintained and supported our main service. Code signing is an essential part of Microsoft’s digital release platform. During this time, I learned this process and provided solutions that maintained and improved its thruput results. Here is a list of the duties I have performed in this role:- SSL certificate renewals with website binding in IIS.- Windows Service deployments and VM patching.- Customer support through a “Direct Response Individual” (DRI) rotation with a ticketed system.- Process automation, reports and alerting using PowerShell and SQL stored procedures.- Find and create bugs to be fixed by the software engineers.- GTM (Global Traffic Manager) configuration for load balancing network traffic.- Successfully completed the “Thales nCSE Certification” course for HSM management.- Integrated the ticket system to the team’s custom alerts. This was completed using PowerShell, consuming the ticket system’s API.- Created troubleshooting guides to complex processes that will prevent the risk of mistakes for DRIs and new employees.- Led daily standup meetings with the team.
