How does Zscaler disrupt command and control channels?

The correct choice describes how Zscaler uses Advanced Threat Protection (ATP) to disrupt command and control channels effectively. Command and control (C2) channels are often exploited by threat actors to maintain communication with compromised systems and to manage executed malware. By leveraging Advanced Threat Protection, Zscaler can detect and block these malicious communications, thereby preventing attackers from issuing commands to their malware or exfiltrating data.

Zscaler's ATP employs technologies such as machine learning, threat intelligence, and behavior analysis to identify suspicious patterns of activity indicative of C2 behavior. This proactive stance ensures that users are safeguarded from potential breaches, as communication pathways established by cybercriminals are intercepted and neutralized.

In contrast to the other options, increasing internet speed does not inherently provide any defense against C2 channels. Establishing new communication protocols would not address the existing threat landscape, and user training and awareness, while beneficial in promoting security hygiene, do not directly counteract the technical tactics used by adversaries to exploit command and control mechanisms.
