Firewalls and Network Security

A firewall is a network security device that monitors packets of incoming and outgoing network traffic for malicious content. After evaluating each packet, it scores it, and based on algorithms, the packet is either blocked or allowed past the firewall. Firewalls area critical line of defense for your network and many times, it’s the first line of defense for your servers. All Firewalls should have their software upgraded every six months with the latest virus signatures and operating system updated. Your Firewall is like a Windows Pc, it needs periodic updates to provide proper security services. Firewalls are normally a hardware device. They also can be delivered as an application, however, there are drawbacks to a pure software-based Firewall.
