Content filtering refers to monitoring and controlling information exchanged over the internet, blocking access to content deemed inappropriate or harmful. Common targets for content filtering include websites undesirable for work environments (such as job portals or external social networking sites), harmful or inappropriate websites for minors (such as adult or dating sites), and ethically or legally objectionable sites (such as those offering illegal drug sales).
Two primary implementation methods for content filtering are:
Dynamic Content Filtering: Real-time monitoring of internet traffic data to detect and block specific keywords or content patterns dynamically.
URL Filtering: Restricting access according to pre-defined URL lists. URL filtering also has significant security benefits, as it enables blocking known phishing websites, thereby preventing phishing attacks. Additionally, by blocking access to "Command and Control (C&C)" servers utilized by malware, URL filtering provides robust defense against information leakage following malware infections.
