Design Security Systems: Firewall engineers review customer requirements for security systems and collaborate with other engineers and developers to decide on an overall technical approach. Once they reach agreement with the customer, they proceed with creating specific designs.
Troubleshoot Issues: Firewall engineers constantly monitor security devices and applications for performance problems, as well address tickets in queue, and provide troubleshooting support for customers. When issues arise, they must analyze the root cause and resolve them promptly or else escalate them to another department while updating customers all throughout.
Write Documentation: Aside from preparing status reports for customers, firewall engineers write extensive documentation on procedures, device statuses, firewall block lists, and other important technical areas. They also create diagrams of network topologies and record details of troubleshooting processes.
Ensure Compliance: Standards and policies are extremely important when it comes to network security, and firewall engineers should be aware of these, keeping abreast of changes and defining processes for compliance. In addition, they enforce quality control and ensure that all output meets project requirements.
