Firewall is a concept of a security system that will helps computers to protect it with unauthorized access or any cyber-attack.
It averts malignant access from computers outside the network. A firewall also works when you want to limit access to outside users. A firewall mainly consists of hardware devices, software programs or a combination of both these. All the messages coming from a network or going to a network have to pass through this firewall. Firewalls are examined by security criteria and the messages which meet these criteria are passed through the network. If the message does not fulfill the criteria then the message is blocked and not sent to the network further. Firewalls can be installed like any software and can be later customized as per needs for getting control over features and security.
