Web Application Firewall (WAF)
A Web Application Firewall is a security system that monitors, filters, and blocks incoming traffic based on predefined rules to protect web applications from various online threats. WAFs can identify and block common web application attacks, such as SQL injection and cross-site scripting (XSS), providing an additional layer of security for your website and its underlying applications.
Transport Layer Security Encryption:
Transport Layer Security (TLS) encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence
Config Server Firewall (or CSF)
Config Server Firewall (or CSF) is an advanced firewall for most Linux distributions and Linux based VPS. In addition to the basic functionality of a firewall – filtering packets – CSF includes other security features, such as login/intrusion/flood detections.
