What is firewall?

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. Firewalls can be hardware-based, software-based, or a combination of both.

Key Functions of a Firewall:

1. Traffic Filtering: It analyzes data packets and determines whether to allow or block them based on security rules.
2. Access Control: Firewalls can restrict access to certain network resources based on user permissions.
3. Threat Detection: They help identify and prevent unauthorized access attempts or malicious activities.
4. Logging and Reporting: Firewalls can log network activity for monitoring and auditing purposes.

Overall, firewalls are essential for protecting networks from cyber threats and ensuring secure communication.
