Which aspect is specifically mentioned in CIP-004 for those with authorized access?

CIP-004 focuses on ensuring that individuals with authorized access to critical infrastructure systems are adequately trained and understand the importance of maintaining robust cybersecurity practices. The reinforcement of cybersecurity practices is essential as it helps mitigate risks associated with unauthorized access and enhances the overall security posture of the organization.

Continuous training and awareness programs for these individuals instill a culture of security, ensuring that they remain vigilant against evolving threats. By emphasizing cybersecurity practices, organizations can better safeguard their assets and sensitive information, ultimately supporting compliance with NERC's objectives in protecting the grid's reliability.

The other options do not align with the intent of CIP-004. Monitoring of performance, providing unlimited internet access, or exempting individuals from training requirements do not directly contribute to maintaining or fostering a secure environment for critical infrastructure.
