Job Description

The WAF engineer works as part of the cybersecurity team to manage and secure web-based applications hosted on-premises and in the cloud. In this role, the WAF engineer is responsible for designing secure WAF configurations that defend against threats and vulnerabilities without impeding the business. The WAF engineer executes controls adhering to policies, monitors against the threat landscape and recommends changes where necessary. Working as part of a team, the WAF engineer shares information and testing effectiveness of controls and collaborates to counter threats and vulnerabilities. The WAF engineer understands the applications in use, where weaknesses may exist and how WAF controls can help thwart vulnerabilities in dynamic and legacy applications. The role is responsible for WAFs maintained by Norfolk Southern (cloud or on-premises) and those managed in tandem with third-party service providers.

 

The WAF engineer is expected to have advanced-level knowledge of web application attacks and best practice controls in defense, including the OWASP Top Ten. The role performs constant testing to detect and verify controls, and ensures security risks to the business are identified, documented and escalated to security managers. The WAF engineer designs, tests, automates and deploys application controls across infrastructure according to security policies and procedures. The role performs ongoing assessments and has basic incident response (IR) skills and experience working with security operations and Network team. Technical and analytical skills are vital in the role, as is the ability to communicate effectively with technical and non-technical colleagues. This role involves understanding evolving adversary tactics. The ideal candidate is highly technical, but with some business acumen, having worked in security administration for several years.

  • Develop and implement workflows to update and maintain configurations across protected infrastructure.
  • Collaborate with incident responders and SOC team members to investigate suspicious activity (analysis and response may need to occur off-hours and on a scheduled rotation).
  • Partner with offensive security team members to test the efficacy of WAF configurations against adversary emulation and enhance team knowledge.
  • Regularly participate in adversary emulation tabletop exercises designed to identify gaps, improve skills, transfer knowledge and improve efficiency at reducing risk.
  • Automate where possible to deploy consistent configurations to WAFs.
  • Work with security team members to enforce thorough application inventory and management standards, as well as audit compliance for applications and services under corporate policies. 
  • Review reports from vulnerability and penetration tests, and results from tabletop exercises, to identify exposure and improve application security posture in tandem with application security engineers.
  • Liaison with threat hunting, infrastructure, information technology, vulnerability management, threat intelligence and software engineer team members.
  • Regularly report to security leadership on security posture supporting defined metrics and service levels.
  • Be professionally accountable for remaining educated on the threat landscape and mitigation techniques.
  • Openly support the organization, management and executive leadership team, even during times of adversity.
  • Perform other duties as assigned.
