Duration 4 Days – 28 hrs.
Overview
The Network Security Operations and Firewall Policy Review Training Course is a comprehensive hands-on program designed for network administrators, security engineers, SOC personnel, and IT professionals responsible for securing enterprise networks. The course provides participants with the knowledge and practical skills required to effectively operate, monitor, manage, and optimize network security infrastructure while implementing firewall policy governance based on industry best practices.
Participants will learn modern network security architecture, firewall technologies, policy lifecycle management, rule optimization, access control strategies, network segmentation, threat detection, logging and monitoring, VPN security, intrusion prevention, and firewall auditing techniques. The training emphasizes operational excellence, risk reduction, compliance, and practical firewall policy review methodologies applicable across major firewall platforms such as Palo Alto Networks, Fortinet, Cisco ASA/Firepower, Check Point, Sophos, Juniper, and similar enterprise solutions.
Hands-on labs, real-world scenarios, policy analysis workshops, and security review exercises ensure participants can immediately apply the concepts within their production environments.
