Designing and Implementing Security Solutions: Network Security Engineers design, implement, and maintain security solutions such as firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), virtual private networks (VPNs), and other security appliances to protect the organization’s network infrastructure.

Firewall Configuration and Management: They configure and manage firewall rules and policies to control incoming and outgoing network traffic, ensuring that only authorized traffic is allowed while blocking malicious or unauthorized access attempts.

Virtual Private Networks (VPNs): They set up and maintain VPNs to provide secure remote access to the organization’s network for employees working from remote locations. This involves configuring encryption protocols and authentication mechanisms to ensure secure communication over public networks.

Monitoring and Incident Response: They continuously monitor network traffic, security logs, and alerts to detect and respond to security incidents on time. This involves investigating security breaches, analyzing the root cause, and implementing measures to prevent future incidents.

Security Incident Analysis and Reporting: They analyze security incidents and breaches to determine the extent of the damage, assess the impact on the organization, and report findings to management, stakeholders, and regulatory authorities as required.
