Filtering Definition: Filtering refers to the process of inspecting and controlling incoming and outgoing network traffic based on predetermined criteria to prevent unauthorized access or malicious activities.
Filtering, in the context of cybersecurity, refers to the process of allowing or blocking data packets based on specified criteria. This criterion can range from IP addresses, protocols, ports, or specific content. Filters are commonly applied at various network levels (e.g., routers, firewalls) to control the flow of data and prevent unauthorized access or malicious activities. Filtering helps organizations in enforcing security policies, minimizing the attack surface, and safeguarding their network infrastructure.
