How are new websites handled in URL Filtering?

New websites are handled in URL Filtering by isolating them to categorize them as safe or harmful. This process is important for maintaining security and ensuring that users are protected from accessing inappropriate, malicious, or unsafe content. By isolating new websites, the system can analyze various factors including the website's reputation, content, and behavior before determining how it should be categorized.

This methodology is crucial because it prevents unverified websites from being immediately accessible, which could pose a risk to users and the organization's network. It balances the need for user access to new and potentially legitimate sites with the requirement to keep the network secure from harmful content.

In contrast, other options imply either a lack of security scrutiny or immediate assumption of safety, which can lead to vulnerabilities in a security-conscious environment. The isolating approach enables a more informed decision on whether a new website should be accessible or blocked, promoting a safer browsing experience.
