Question
Which Cisco firewall solution supports configuration via Cisco Policy Language?
A. NGFW
B. CBAC
C. IPS
D. ZFW
Answer
D. ZFW
Explanation
Cisco’s Zone-Based Firewall (ZFW) is the firewall solution that supports configuration via the Cisco Policy Language (CPL).
ZFW is a Cisco IOS software feature that provides a stateful approach to firewall policy enforcement. Unlike traditional interface-based firewalls, ZFW introduces the concept of security zones, which are logical groupings of interfaces with similar functions or features. Interfaces within a given zone can communicate freely, while traffic between different zones is subjected to policy restrictions.
One of the key advantages of ZFW is its use of CPL for configuration. CPL is a high-level, descriptive language that allows administrators to define security policies in a more intuitive and reusable manner compared to traditional access control lists (ACLs). CPL policies are mapped to security zones, enabling a hierarchical and modular approach to policy management.
In contrast, other Cisco firewall solutions mentioned have the following characteristics:
- NGFW (Next-Generation Firewall): Refers to a broad category of firewalls that offer advanced features beyond basic packet filtering, such as application awareness, intrusion prevention, and cloud-delivered threat intelligence. While some NGFW solutions may use CPL-like languages, it is not a defining characteristic of NGFW.
- CBAC (Context-Based Access Control): A legacy Cisco IOS firewall feature that provides stateful inspection capabilities. CBAC does not use CPL for configuration.
- IPS (Intrusion Prevention System): A security device or software that monitors network traffic for malicious activities and can take preventive actions. IPS is often integrated with firewalls but is not a firewall solution itself and does not use CPL.
Therefore, among the given options, only ZFW (Zone-Based Firewall) supports configuration through the Cisco Policy Language.
