  • Worked with Line of Business to help them understand the remediation process which included written documentation
  • Remediated 10’s of thousands of vulnerabilities across all lines of business at FIS
  • Wrote scripts to automate vulnerability remediation for Linux and Unix servers in bash and korn shell
  • Worked with many application and OS groups to help them understand what fixes had to go into place to remediate their vulnerabilities
  • Careful planning to make sure that there were no outages when remediating vulnerabilities
  • Wrote 100’s of detailed plans (outlines/remediation documents) that contained all the steps to remediate operating system and application vulnerabilities
  • Continue to review and update all remediation documents every year to ensure process accuracy
  • Started to automate many of the vulnerability fixes through Hewlett Packard System Administration
  • Started to automate many of the vulnerability fixes through Bigfix, which is still the tool choice of today at FIS
  • Took the lead roles to implement the CIS hardening standards for Red Hat, CentOS and Oracle Enterprise Linux, all Linux OS versions
  • Scripted over 300 per OS level benchmarks that would include in all scripts, a check function, a fix function and a rollback function
  • These scripts are heavily used through the entire company to harden new and existing servers
  • Maintain 20+ scripts for the secure configuration management program
  • These scripts are vital to the success of FIS build and automation processes
  • Every server must be run through the Secure Configuration Management program and the scripts have to be 99% accurate to ensure that all newly built server are @98% or better before they are allowed on the production floor
  • Converted all of the Security Vulnerability Management scripts to the same type format as the CIS/SCM script, they too contain a check, fix and rollback
  • The rollback is absolutely required for every remediation script because it allows for any fix to be rolled back in case there is a reported issue/outage
  • Enforce Audit and PCI findings from Rapid7 Nexpose and Pentest
  • If and when an issue is discovered with any CIS/SCM or SVM script, the problem is immediately fixed, tested and sent out for use as soon as the testing is completed.
  • Most script issues are resolved and tested within a few hours
  • Started working with Bigfix to create relevance fixlets to deploy, install and configure software for many plication teams across FIS.
  • Moved over to start working with Bigfix as a master operator, 50% of my workday.
  • Acted as a team leader in group projects, delegating tasks and providing feedback.
  • Adaptable and proficient in learning new concepts quickly and efficiently.

  • Working as a team to get machines back online after a system crash due to a hardware failure or some type of system issues from the Operating System level
  • Setting up all system process under SMF, so that it becomes a standard startup under the system rather than an outside startup script that has to be maintain and designed, this helps move the processes to the SMF format from machine to machine much easier
  • Using Tivoli to push out data center changes and updates to all systems supported to make sure there is a GOLD standard across all servers
  • Enforce audit requirement and adhere to audit finding to get the system up to spec across the entire environment, make changes that exceed the audit finds and write script to validate their requirements and store off site for proof of all changes to satisfy audit
