Developer's Description
Firewall developers are responsible for designing and developing protective measures to keep IT infrastructure systems safe from external security breaches. They also manage the security infrastructure of IT systems.
Firewall developers’ duties include:
- Designing, implementing, and maintaining firewall policies
- Configuring and managing firewalls, intrusion detection/prevention systems, and web filtering proxies
- Monitoring network traffic and activity logs to identify potential security threats
- Installing hardware
- Setting up virtual private networks (VPNs)
Firewall developers should have advanced knowledge of computer security and networking. They should also be familiar with the underlying theories and be able to diagnose issues, build infrastructure, and work with related software.
