How should newly registered domains be handled in cybersecurity practices?

Newly registered domains often pose a heightened risk in cybersecurity because they can be associated with malicious activities such as phishing, scams, or command and control servers for malware. Cybercriminals frequently utilize these new domains to launch attacks since they are less likely to be blacklisted and can bypass security measures that are in place for established domains.

Treating newly registered domains as high-risk and potentially blocking access is a prudent approach. This allows organizations to mitigate the risk of falling victim to cyber threats that these domains could pose. It is essential to conduct further assessment and monitoring of these domains before granting them access to the network, as this helps in protecting sensitive information and maintaining the integrity of systems.

Other options do not align with best cybersecurity practices. Allowing unrestricted access to newly registered domains increases the likelihood of exposure to malicious content. Monitoring traffic only during working hours is insufficient, as threats can occur at any time, and automatic registration of domains as safe could lead to significant vulnerabilities by trusting potentially harmful entities without proper scrutiny.
