Roles & Responsibilities

Palo Alto Administration:

• Firewall Management : Configure, maintain, and troubleshoot Palo Alto firewalls to ensure optimal performance and security.
• Policy Management : Create, implement, and update security policies (NAT, security rules, application control, URL filtering, etc.) to meet organizational security standards.
• Traffic Analysis : Monitor network traffic and security logs for unusual activity and ensure appropriate filtering of traffic.
• VPN Configuration : Set up, maintain, and troubleshoot VPN solutions, including GlobalProtect and site-to-site VPNs.
• Updates & Patches : Manage and apply firewall firmware and software updates/patches to mitigate vulnerabilities.
• High Availability (HA) & Redundancy : Configure and maintain Palo Alto HA clusters to ensure continuous network security service availability.
• Logging & Reporting : Configure logging and reporting on Palo Alto firewalls, ensuring all security events are captured and integrated into SIEM solutions.

SIEM Analysis and Management (FortiSIEM):

• FortiSIEM Administration : Configure, manage, and optimize FortiSIEM for log collection, analysis, and correlation from various security devices, including firewalls, intrusion detection/prevention systems (IDS/IPS), and servers.
• Incident Detection & Response : Analyze FortiSIEM alerts for signs of security incidents, identify threats, and take proactive or reactive actions to mitigate risks.
• Log Aggregation & Analysis : Configure log sources and fine-tune alert thresholds to ensure relevant and actionable security data is captured.
• SIEM Optimization & Tuning : Tune SIEM rule sets, reports, and dashboards to minimize false positives and improve detection accuracy.
• Compliance & Reporting : Generate compliance reports and security metrics using FortiSIEM , aligning with regulatory requirements such as GDPR, PCI-DSS, HIPAA, and others.

DDoS Protection Management (Radware/Imperva):

• DDoS Protection Configuration : Administer and configure DDoS mitigation solutions using Radware and Imperva to protect against volumetric, application-layer, and infrastructure-layer DDoS attacks.
• Traffic Monitoring & Analysis : Continuously monitor network traffic for signs of potential DDoS attacks, leveraging Radware and Imperva to detect and mitigate abnormal traffic patterns.
• Incident Response & Mitigation : Respond to DDoS incidents in real-time, leveraging automated protection mechanisms in Radware and Imperva to minimize service disruption.
• Performance Tuning : Ensure DDoS protection solutions are optimized to balance security and network performance, making necessary adjustments as attack patterns evolve.
• Reporting & Documentation : Generate and review attack reports, documenting incident timelines, mitigation actions, and lessons learned. Ensure reports are accessible for future analysis and compliance purposes.

Network Infrastructure & Routing (BGP & Network Skills):

• Network Design & Optimization : Design, configure, and maintain network infrastructure to ensure high availability, scalability, and security.
• BGP Configuration & Management : Administer and configure BGP routing for multi-site or multi-cloud environments, ensuring optimal route selection, failover, and network redundancy.
• Routing Protocols : Configure and troubleshoot routing protocols such as BGP , OSPF , EIGRP , and Static Routes to ensure optimal network performance.
