In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on configurable security rules. [ 1 ] [ 2 ] A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet , [ 3 ] or between several VLAN s.
Context-based access control (CBAC) is a feature of firewall software, which intelligently filters TCP and UDP packets based on application layer protocol session information. It can be used for intranets, extranets and internets. [1]
A firewall is a system or group of systems (router, proxy, or gateway) that implements a set of security rules to enforce access control between two networks to protect the "inside" network from the "outside" network. They filter all traffic regardless of its origin—the Internet or the internal network.
The following are examples of commonly-deployed middleboxes: Firewalls filter traffic based on a set of predefined security rules defined by a network administrator. IP firewalls reject packets "based purely on fields in the IP and transport headers (e.g., disallow incoming traffic to certain port numbers, disallow any traffic to certain subnets etc.)" [1] Other types of firewalls may use more ...

The concept of ABAC can be applied at any level of the technology stack and an enterprise infrastructure. For example, ABAC can be used at the firewall, server, application, database, and data layer. The use of attributes bring additional context to evaluate the legitimacy of any request for access and inform the decision to grant or deny access.
An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from. The two primary categories of application firewalls are network-based and host-based.
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1]
