A Firewall is a network security device that monitors incoming and outgoing network traffic. A Firewall enforces an organization’s security policy by filtering network traffic. At its most basic a Firewall is essentially the boundary or barrier between two networks to identify threats in incoming traffic and blocks specific traffic, once flagged by a defined set of security rules, while allowing non-threatening traffic through.
Firewalls have existed since the late 80’s and started as “packet filters,” which were networks set up to examine packets transferred between computers. They’ve come a long way since then, but the basic principle behind why they’re so important remains: You’re setting up your network with rules for users and protecting your network from threats.
A Firewall is a necessary part of daily computing and takes the guesswork out of your hands and entrusts it to your network security device. Firewalls, and especially Next Generation Firewalls, focus on blocking malware and application-layer attacks, along with an integrated intrusion prevention system (IPS), these Next Generation Firewalls are able to react quickly and seamlessly to detect and react to outside attacks across the whole network. They can set policies to better defend your network and carry out quick assessments to detect invasive or suspicious activity, like malware, and shut it down.
Every network needs malware defense, and advanced malware defense involves many layers of safeguards, including continuous network scans. There are many types of malware that a Firewall can protect against, including:
Every system needs protection and there is no better way to have a broad spectrum of protection, and peace of mind, knowing that the computer system you use is completely protected from any and all types of malware and threats.
