Description: A zonal firewall is a network security device that applies security policies to specific zones within a network infrastructure. Unlike traditional firewalls that protect the entire network, zonal firewalls allow for segmenting the network into different areas or ‘zones’, each with its own access rules and policies. This provides more granular control over network traffic, enabling organizations to define what type of traffic is allowed or denied in each zone. Zones can be based on various criteria, such as the function of systems, the sensitivity of data, or the trust level of users. This segmentation enhances security by limiting lateral movement of threats within the network and facilitates compliance with security regulations and standards. Zonal firewalls are essential in environments handling sensitive data or requiring a high level of security, such as financial institutions, healthcare organizations, and technology companies. Additionally, their integration with security orchestration and automation systems allows for quicker and more efficient responses to security incidents, improving the overall security posture of the organization.
