Discussion

Malicious code protection mechanisms include, but are not limited to, antivirus and malware detection software. To minimize potential negative impact to the organization that can be caused by malicious code, it is imperative that malicious code is identified and eradicated. This setting configures devices to allow or block connections to IP addresses, domains, or URLs in custom indicator lists.
