Managing PKI effectively requires continuous monitoring for expired or compromised certificates and ensuring that automated processes support lifecycle management. Candidates are expected to demonstrate practical knowledge of certificate deployment, validation, and revocation processes while integrating these mechanisms into broader security frameworks.

Endpoint security management is another central theme of the HPE6-A84 exam. Professionals must be able to profile devices, assess risks, classify endpoints, and apply dynamic access controls based on compliance status and risk scores. Effective endpoint management helps organizations detect non-compliant devices, remediate security gaps, and enforce policies that prevent unauthorized access. Automation plays a critical role in responding to threats, minimizing human error, and ensuring timely remediation. Candidates must understand how to monitor endpoint behavior continuously and adjust policies dynamically to maintain optimal security while accommodating legitimate network activity.

Threat detection and response are essential for proactive security management. Candidates must be capable of analyzing logs, correlating alerts, and identifying anomalies across both wired and wireless networks. Advanced analytics and automated workflows allow professionals to prioritize risks, remediate threats, and refine detection methods continuously. Proactive threat management minimizes the likelihood of breaches and strengthens the network's overall resilience. Candidates must understand both signature-based and anomaly-based detection strategies, as well as how to design response workflows that minimize disruption while addressing incidents effectively.

Role-based access control is another key skill area, enabling organizations to enforce consistent security policies. Candidates must design RBAC frameworks that assign privileges based on user roles, device types, and compliance levels. This includes integrating RBAC with Aruba ClearPass, dynamically adjusting access based on context, and ensuring sensitive resources are protected. RBAC helps organizations maintain a principle of least privilege, reducing exposure to threats while allowing users to perform their tasks efficiently.

Dynamic segmentation and policy enforcement further enhance enterprise security. Candidates are expected to implement policies that automatically assign users and devices to appropriate security zones based on compliance, role, and risk. Dynamic segmentation simplifies management, improves security, and prevents lateral movement of threats. It is especially effective in environments with mixed wired, wireless, and remote users, ensuring that access is tailored to each device's risk profile.

The use of analytics and continuous improvement is vital for maintaining a proactive security posture. Candidates must leverage tools like the Network Analytics Engine to monitor network activity, detect anomalies, and refine security policies. Analytics allow organizations to anticipate risks, optimize resource allocation, and continuously improve defensive measures. Security management is an iterative process, and candidates must be able to evaluate trends, adjust thresholds, and respond to emerging threats with agility.

Incident response and remediation workflows are critical for minimizing the impact of security events. Professionals must design workflows to isolate compromised devices, remediate vulnerabilities, and coordinate responses across multiple security systems. This includes defining notification protocols, automating corrective actions, and ensuring minimal disruption to business operations. Effective incident response planning reduces recovery time and ensures that security measures remain robust even under pressure.

Securing wide area networks and remote access points is another integral aspect of the HPE6-A84 exam.
