In a Next-Generation Firewall (NGAF) like Sangfor's, both Local Access Control List (ACL) and Application Control serve as mechanisms to control and manage network traffic, but they function in different ways. Local ACL and Application Control are both used to control network traffic, but they operate at different layers of the OSI model and focus on different aspects of the traffic. Local ACL primarily deals with IP-related information, while Application Control examines application-level content and behavior. Both features can be used together to provide a more comprehensive and secure network environment.


1. Local ACL (Access Control List):
An ACL is a set of rules that define how traffic is allowed or denied based on specific criteria, such as source and destination IP addresses, ports, and protocols. A Local ACL is configured directly on the NGAF device, and it operates at the network layer (Layer 3) of the OSI model. It primarily focuses on controlling traffic based on IP-related information.

Key features of Local ACL:

* Filters traffic based on IP addresses, ports, and protocols.
* Can be used to allow or deny specific traffic.
* Operates at Layer 3 (Network Layer) of the OSI model.
* Can be static (manually configured) or dynamic (based on user-defined policies).

2. Application Control:
Application Control is a more advanced feature that focuses on controlling traffic based on the applications running on the network. It goes beyond the IP-related information and examines the content and behavior of the applications. Application Control operates at the application layer (Layer 7) of the OSI model, allowing for more granular control over network traffic.

Key features of Application Control:

* Filters traffic based on the applications running on the network.
* Can be used to allow, block, or control specific applications.
* Operates at Layer 7 (Application Layer) of the OSI model.
* Offers deep packet inspection (DPI) to identify and classify applications.
* Can be used to enforce usage policies, monitor application performance, and prevent potential security threats.
