Infrastructure Security Design

What you'll be doing:

Working under direct supervision, you will apply your developing expertise in network security, infrastructure technologies, and security controls to support the design, implementation, and maintenance of secure infrastructure solutions. You will contribute to infrastructure security projects, perform security configurations, and develop your skills across network security technologies while receiving regular guidance from senior team members.

• Assist in implementing network security controls including firewalls, IPS/IDS, and proxies under supervision
• Configure basic network security policies and access control lists following approved designs
• Support network segmentation implementations and VLAN configurations
• Assist with VPN setup and secure remote access solution deployments
• Document network security configurations and changes accurately
• Perform routine security device maintenance and updates under guidance

• Support deployment and configuration of security technologies including SIEM, EDR, and endpoint protection
• Assist in integrating security tools with existing infrastructure under supervision
• Configure security monitoring rules and alerts based on approved templates
• Support security technology testing and validation activities
• Maintain security tool inventories and configuration documentation
• Troubleshoot basic security technology issues with senior guidance

• Apply security hardening standards to servers, workstations, and network devices under supervision
