What is a Firewall?
A website firewall is a security system that monitors and controls incoming and outgoing network traffic to and from a website based on certain rules and criteria. Its purpose is to protect the website from various cyber threats, such as hacking attempts, malware, and DDoS attacks.
Why use a firewall?
A server firewall is used to enhance the security of a server by controlling incoming and outgoing network traffic based on predefined security rules. The primary reasons to use a server firewall are:
- Protect against external threats: A server firewall helps to block unauthorized access to the server, including hacking attempts and malware.
- Secure sensitive information: Servers often store sensitive data, and a firewall helps to prevent unauthorized access to that data.
- Compliance with security regulations: Some industries have strict security regulations that require the use of firewalls to protect sensitive data.
- Control network access: A firewall allows administrators to control which types of network traffic are allowed to enter or leave the server, helping to maintain network security.
