Responsibility

Correct stakeholder

Responsible for supporting, troubleshooting, and monitoring the wired/wireless infrastructure

Network Operations

Responsible for investigating IDS/IPS incidents and managing firewalls

Security Operations

Responsible for establishing security policy and selecting security controls for the infrastructure

CISO

Responsible for authoring the low-level design, and creating the configuration to meet the technical requirements

Network Design/Architecture

Clearly defined stakeholder responsibilities are essential for network projects involving multiple technical disciplines and organizational teams.

Network Operations maintains the availability and performance of the deployed infrastructure. Its responsibilities include monitoring switches and access points, investigating connectivity problems, managing incidents, and performing routine operational maintenance.

Security Operations focuses on the operational defense of the environment. This team investigates intrusion detection and prevention events, reviews security alerts, manages firewall operations, and responds to suspected security incidents.

The Chief Information Security Officer (CISO) provides strategic security leadership. Responsibilities include defining security policies, establishing risk-management priorities, selecting appropriate security controls, and ensuring that network security aligns with business and compliance requirements.

Network Design/Architecture is responsible for translating requirements into technical solutions. This includes developing logical and physical designs, defining switching and routing architecture, specifying configuration requirements, and producing technical implementation documentation.

Although these responsibilities can overlap, separating policy ownership from implementation and operational monitoring establishes clear accountability.

For an HPE Aruba Networking deployment, the architecture team may define ClearPass-based security and AOS-CX switching requirements, while operations teams maintain the resulting infrastructure.

The project governance model should document these responsibilities before detailed design and implementation begin.
