Firewall Administration - Security Management

Firewall Administration - Security Management

Roles and Responsibilities:

• Firewall Management:

  Design, configure, implement, and maintain various firewall technologies (e.g., Palo Alto Networks, Cisco ASA/Firepower, Fortinet FortiGate, Check Point) across our network infrastructure.

• Security Policy Enforcement:

  Develop, implement, and manage firewall rules, security policies, VPNs (Site-to-Site, Remote Access), and NAT configurations to enforce security postures and access controls.

• Threat Prevention:

  Configure and optimize advanced security features on firewalls such as Intrusion Prevention Systems (IPS), URL filtering, application control, anti-malware, and deep packet inspection.

• Network Segmentation:

  Implement and maintain network segmentation strategies using firewalls to isolate critical systems and reduce the attack surface.

• Monitoring & Alerting:

  Proactively monitor firewall logs, security events, and performance metrics. Configure alerts and dashboards to detect and respond to potential security incidents.

• Troubleshooting:

  Perform in-depth troubleshooting and root cause analysis for complex network security issues, connectivity problems, and performance degradation related to firewalls.

• Vulnerability Management:

  Assist in identifying firewall vulnerabilities and implementing necessary patches, upgrades, or configuration changes to enhance security.

• Documentation:

  Create and maintain comprehensive documentation for firewall configurations, network security policies, diagrams, and operational procedures.

• Collaboration:

  Work closely with network engineers, security operations center (SOC) analysts, application teams, and other IT departments to ensure integrated and effective security solutions.

Preferred Candidate Profile:

• Firewall Expertise:

  Strong hands-on experience in the administration, configuration, and troubleshooting of enterprise-grade

  firewall platforms

  (e.g., Palo Alto Networks, Cisco, Fortinet, Check Point).

• Network Security Fundamentals:

  In-depth understanding of network security principles, protocols (TCP/IP, UDP, ICMP), routing, switching, and VPN technologies.

• Security Concepts:

  Solid knowledge of cybersecurity concepts, threat landscapes, common attack vectors, and defense mechanisms.

• Problem-Solving:

  Excellent analytical and problem-solving skills with a methodical approach to diagnosing and resolving complex security and network issues.

• Communication:

  Strong verbal and written communication skills to articulate technical concepts and security findings effectively.

• Certifications (Plus):

  Industry-recognized security certifications (e.g., Palo Alto PCNSA/PCNSE, Fortinet NSE, Cisco CCNA Security/CCNP Security, CompTIA Security+) are highly desirable.

• Education:

  Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or a related technical field.
