How does DNS filtering enhance security?

DNS filtering enhances security primarily by preventing access to malicious domains. When users attempt to visit a website, DNS filtering checks the requested domain against a database of known malicious sites. If the domain is flagged as harmful, the filtering process can block the resolution of that domain, thus thwarting potential threats such as malware downloads, phishing attempts, and other cyberattacks that often originate from these harmful sites.

This proactive approach not only helps in protecting users but also minimizes the risk of data breaches and the spread of malware within the network. By controlling which domains can be accessed, organizations can maintain a safer browsing environment for end-users and safeguard sensitive information.

In contrast, options related to speeding up internet connections or providing data storage solutions do not directly contribute to security. Organizing network traffic is more about managing the flow and prioritization of data rather than enhancing security through domain access controls. Thus, the emphasis on blocking access to malicious domains clearly defines the critical role of DNS filtering in a broader cybersecurity strategy.
