Jan 1, 2015 · A context firewall is a sophisticated cybersecurity measure that goes beyond traditional firewalls. While traditional firewalls focus on blocking specific network ports or IP addresses, context firewalls take into account the context and content of network traffic.

Mar 18, 2016 · The security context definition in the system configuration identifies the context name, configuration file URL, interfaces that a context can use, and other settings.

Sep 21, 2021 · Cisco ASA supports multiple firewall contexts, also called firewall multimode or multi-context mode. Multi-context mode divides a single ASA into multiple virtual devices, also known as security contexts.

In Cisco ASA, these virtual firewalls are known as security contexts. This chapter covers security contexts in detail. The configuration of a security context is broken down into seven steps: Enable multiple security contexts globally. Set up the system execution space. Specify a configuration URL. Allocate the interfaces.

Jan 15, 2025 · This article describes how to use the netsh advfirewall firewall context instead of the netsh firewall context to control Windows Firewall behavior.

Each standalone firewall acts and behaves as an independent entity with its own configuration, interfaces, security policies, routing table, and administrators. In Cisco ASA, these virtual firewalls are known as security contexts. This chapter covers security contexts in detail.

The most important firewall features can be considered context-dependent, varying greatly based on the specific security requirements and the network architecture of an organization.

Firewall contexts provide policy-based access control to and from address and port pairs, inside and outside the network. Firewall properties include the firewall name, an (optional) description, its partition, its type, and its parent device on the partition in which it resides.

Each security context defines a single virtual firewall, complete with its own configuration—and just as with physical devices, each security context must be correctly configured, or overall security can be compromised.

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.
