Firewalls: Essential Legal Insights and Definitions for Cybersecurity

Q: Do I need a firewall if I have antivirus software?

Yes, firewalls and antivirus software serve different purposes and should be used together for comprehensive protection.

Q: How often should I update my firewall?

It is recommended to update your firewall regularly, especially when new threats are identified or when your network configuration changes.

Definition & Meaning

A firewall is a security system that protects a computer network by monitoring and controlling incoming and outgoing traffic. It acts as a barrier between a trusted internal network and untrusted external networks, such as the Internet. Firewalls can be implemented as hardware devices, software applications, or a combination of both. Their primary purpose is to prevent unauthorized access and ensure that only legitimate traffic is allowed through.
