Firewalls

A firewall is a security device — computer hardware or software — that can help protect your network by filtering traffic and blocking outsiders from gaining unauthorized access to the private data on your computer. Not only does a firewall block unwanted traffic, it can also help block malicious software from infecting your computer.  What is Firewalls in information security? A firewall can be represented as a specific type of network security device or a software program that monitors and filters incoming and outgoing network traffic based on a represented group of security rules.  Firewalls can either be software or hardware, though it’s best to have both. A software firewall is a program installed on each computer and regulates traffic through port numbers and applications, while a physical firewall is a piece of equipment installed between your network and gateway.  A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.  Firewalls Firewalls Firewalls Firewalls Firewalls Firewalls Firewalls Firewalls
