FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Windows and macOS have built-in firewalls – software designed to create a barrier between your information and the outside world. Firewalls prevent unauthorized access to your business network and alert you to any intrusion attempts.

Detailed explanation-2: -A network firewall is a security device that monitors all incoming and outgoing traffic on a private network. Network firewalls work like device-specific firewalls, but they protect an entire network by blocking unauthorized access, which protects all the devices connected to that network.

Detailed explanation-3: -A firewall is software or firmware that prevents unauthorized access to a network. It inspects incoming and outgoing traffic using a set of rules to identify and block threats.

Detailed explanation-4: -A firewall may be secure, but if it’s protecting an application or operating system with vulnerabilities, a hacker can easily bypass it. There are countless examples of software vulnerabilities that hackers can exploit to bypass the firewall.

Detailed explanation-5: -The security systems will allow or block data packets based on existing security rules. Firewalls build checkpoints that filter web traffic. These systems let you review and act upon rogue network traffic before the attacked network experiences any adverse effects.
