Cisco Firewalls ASA

Cisco Firewalls ASA or Series Adaptive Security Appliances, or simply Cisco ASA, is Cisco’s line of network security devices introduced in May 2005.

Cisco Firewalls ASA has become one of the most widely used firewall/VPN solutions for small to medium businesses. Early reviews indicated the Cisco GUI tools for managing the device were lacking.

A security flaw was identified when users customized the Clientless SSL VPN option of their ASA but was rectified in 2015. Another flaw in a WebVPN feature was fixed in 2018.

What are the Cisco Firewalls ASA and How Does It Work?

Cisco Firewalls ASA are Adaptive Security Appliances, or ASA, a piece of cybersecurity hardware sold by Cisco. ASAs are multi-purpose security devices. They boast firewall, antivirus, intrusion protection, and VPN capabilities.

How Cisco Firewalls ASA Secure a Network?

A Cisco Adaptive Security Appliance’s (ASA) default behavior is to prevent all external traffic from entering a network. Rogue actors can’t perform mischief if they never get in from the outside in the first place. But Cisco has also built ASAs to have highly intelligent and robust capabilities that can recognize permissible traffic of many different types.

In the world of cybersecurity, there are many types of protection. Different hardware and software solutions offer unique protections. A Cisco Adaptive Security Appliance, or ASA, is especially powerful because it bundles many features and capabilities into one network security device.

To understand what an ASA does on a network, let’s picture one. Imagine a network and give it an “inside” zone and a “demilitarized zone” (DMZ) of several servers that touch the internet, then put an ASA in between the network and the Internet – protecting the entire network.

We all know that the outside world is a dangerous place. And so the ASA, by default, says that any traffic trying to come in from the outside, whether that’s a user, a server, or a system, is going to be denied at the connection to the ASA. When a network has an ASA protecting it, outside traffic gets stopped before it can even make its way to any device on the network.

The only way to keep a network absolutely safe is to allow absolutely no connection to the Internet. But you can imagine why that’s usually not very useful. Using the internet isn’t optional for most companies — and that means users can leave the internal networks for the outside world and receive replies. It also means allowing valid requests from the internet to reach web servers.

An ASA’s default behavior may be to allow no packets through to either the inside zone or the DMZ, but it has a host of bells and whistles that make safe, valid interaction with the internet possible.
