  • 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.
  • Network Performance Monitoring: Use tools to monitor network performance, diagnose network issues, and ensure high network uptime.
  • Connectivity & Redundancy: Implement redundant network configurations, including link aggregation, failover strategies, and network resilience techniques for mission-critical applications.
  • Cloud Networking: Experience with cloud-based network configurations (AWS, Azure, GCP) and integrating them with on-premise network infrastructure.
  • IP Subnetting & VLAN Configuration: Manage and optimize IP address management (IPAM), subnets, VLANs, and ensure proper segmentation within the network infrastructure.

L3 Firewall Expertise:

  • L3 Firewall Configuration: Configure and manage advanced L3 (Layer 3) firewall policies, including routing and security settings, on multiple firewall platforms.
  • Traffic Control & Filtering: Implement and troubleshoot traffic filtering rules for IP traffic, subnets, and protocols, ensuring proper segmentation and control between networks.
  • Advanced Routing & Firewall Integration: Configure firewall policies based on routing protocols (such as BGP, OSPF, etc.) and integrate firewalls with routing protocols for optimized traffic management and security.
  • Firewall Troubleshooting & Optimization: Analyze complex firewall configurations, identify issues, and optimize firewall performance by adjusting rules, policies, and routing settings.
  • Security Policy Management: Create, review, and update security policies for L3 firewall implementations, ensuring compliance with security best practices and organizational requirements.
